Ingredients You’ll Need
This is what I call a life-changing dessert—quick, easy, and made with pantry staples. If you’ve got a sweet tooth (same), you need to try this vanilla cake in the microwave. Here’s a fast breakdown of the ingredients:
- Flour: All-purpose or self-rising. If using self-rising, adjust baking powder.
- Sugar: Granulated is best for texture, but feel free to experiment with brown or powdered sugar.
- Baking Powder: Check that expiration date! Old leavening = flat cake.
- Milk: Use 2% or higher for the best texture. Non-dairy options work, but results vary.
- Butter: Butter gives the best flavor and fluffiness. You can sub with oil or applesauce—but why would you?
- Vanilla: Go with pure vanilla for flavor. You can mix in a little almond extract or use vanilla bean paste for a boost.
Simple, fast, and dangerously delicious.
Jesseca’s Recipe Review
This vanilla mug cake is my go-to when I need dessert now and don’t want to share. It’s soft, sweet, and hits that cake craving in under five minutes—no mixer, no mess, no judgment. I’ve tested a ton of mug cakes over the years, and this one’s the perfect balance of fluffy and moist with just the right vanilla flavor.
Tip from Jesseca:
Don’t overcook it! Start with one minute and add a few seconds if needed. The cake keeps cooking after the microwave stops, so slightly underdone is actually perfect.
Substitutions and Variations
This is such a forgiving cake recipe. We’ve made it about a dozen times and tried a few substitutions. Here are some ideas that might work for you!
- Lower the amount of sugar from two tablespoons to one for a less sweet cake.
- Substitute nut milk or soy milk for a dairy free mug cake.
- You can also substitute the butter for a flavorless oil like coconut oil, avocado oil, or applesauce.
- This is a great recipe for a small mug. For larger mugs, or for sharing, you can easily double this recipe.
- Don’t forget to try other flavors like my Snickerdoodle Mug Cake or my son’s favorite Cinnamon Roll Mug Cake!
How to Make A Vanilla Mug Cake
Not to brag, but this is easily the best mug cake. As far as single-serving desserts go – it’s quick, easy, and so incredibly moist and fluffy! Be sure to look at the comments for some great suggestions.
- Prep Your Mug: Use a microwave-safe mug big enough for the batter to rise. Grease lightly if you want, but it’s optional.
- Mix Dry Ingredients: Add flour, sugar, and baking powder to the mug and whisk to combine.
- Add Wet Ingredients: Stir in milk, melted butter (or oil), and vanilla until smooth. Fold in sprinkles if using.
- Microwave: Cook on high for 1–2 minutes, checking doneness with a toothpick. Add more time in short bursts if needed.
- Serve & Enjoy: Let it cool for a minute, then top with whipped cream, ice cream, or sprinkles if you’re feeling fancy. Dig in!
Storage and Make-Ahead Instructions
Mug cakes are best enjoyed fresh, but if you’ve got leftovers (rare, but it happens), let the cake cool completely and cover the mug with plastic wrap or transfer the cake to an airtight container. It’ll keep in the fridge for up to 2 days.
To reheat: Pop it in the microwave for about 15–20 seconds until warm.
Make-ahead tip: Want to speed things up even more? Mix the dry ingredients in a small airtight container or jar for a DIY mug cake mix. When the craving hits, just add the wet ingredients and microwave!
Recipe FAQs
Baking powder is what helps the cake rise and stay fluffy. If you skip it, the cake will be dense. No baking powder? Try 1/8 tsp baking soda plus a few drops of vinegar or lemon juice as a backup.
Yes! Use the same amount of neutral oil (like canola or vegetable). The flavor will be slightly different, but the texture still works.
Your mug was probably too small. Make sure it holds at least 12 oz and only fill it about halfway with batter to give it room to rise.
Mug cakes are best fresh, but you can mix the dry ingredients in advance and store them in a jar. Just add wet ingredients and microwave when ready.
It was likely overcooked. Start with 1 minute and add time in small bursts—microwaves vary a lot in power.
It’s better to make two individual cakes. Doubling in one mug can lead to uneven cooking and overflowing batter.

Easy Vanilla Mug Cake Recipe
Ingredients
- 4 tablespoons all-purpose flour
- 2 tablespoons granulated sugar
- 1/2 teaspoon baking powder
- 1/4 cup milk
- 1½ tablespoons butter (melted, or oil)
- 1/2 teaspoon vanilla extract
- 1 tablespoon sprinkles (optional)
Instructions
- You can lightly grease the inside of the mug with a bit of butter or oil to prevent sticking, but it's not necessary.
- In the mug, whisk together the all-purpose flour, granulated sugar, and baking powder until well combined. This will ensure that your mug cake rises properly and has a nice texture.
- Pour in the milk, melted butter or oil, and vanilla extract into the mug with the dry ingredients. Stir everything together until you have a smooth batter. If you're adding sprinkles, gently fold them into the batter now.
- Place the mug in the microwave and cook on high for about 1 to 2 minutes, depending on the wattage of your microwave. Start with 1 minute and check the cake's doneness by inserting a toothpick into the center. If it comes out clean, your mug cake is ready. If not, continue microwaving in 15 to 30-second intervals until done. Remember, cooking time will vary depending on your microwave wattage.
- Carefully remove the mug from the microwave (it will be hot!) and let it cool for a minute or two. You can enjoy the mug cake directly from the mug or transfer it to a plate. If desired, you can add a dollop of whipped cream, a scoop of vanilla ice cream, or extra sprinkles on top for decoration.
- Grab a spoon and dig into your warm and delicious vanilla mug cake! Enjoy it as a quick and satisfying dessert anytime you need a sweet treat fix.

Notes
- This recipe will not require a large mug, however if you decide to double the recipe keep a close eye as it will rise over the top of your glass.
- Swap the sprinkles for chocolate chips for a fun twist.
- Serve topped with fresh berries and whipped cream (my favorite) for a quick treat.
- This recipe is not oven safe. Please do not try to bake this recipe.
- If your cake does not rise, be sure to check the expiration date of the baking powder and make sure it hasn’t passed.

very flavourful & easy, but after tries mine still come out slightly custardy, what can I possibly be doing wrong?
I did 1 minute, next a 1 min 20 sec, next 1 min 40 sec, still custardy.
really great flavor, minimal time & husband likes so it’s a win-win.
when I get it figured out I will next try the cinnamon roll cake!!
Thank you so much for the kind words, Laura! It sounds like you’re almost there! If it’s coming out custardy, it might be the power of your microwave. Every microwave is a little different, so you might need to cook it in small increments (like 10-15 seconds) until it’s fully set. Also, make sure you’re not overmixing the batter—it can affect the texture. I’m so glad you’re enjoying the flavor, and I can’t wait for you to try the cinnamon roll cake next! Let me know if that one’s a hit too!
Very yummy! I made this because I saw my mom making herself a red velvet version and it looked yummy. I will admit I was a little concerned after mixing everything together because it looked more liquid than I thought it was supposed to, (given I don’t know much, I don’t bake) but I decide to leave it alone and trust the recipe and was very happy. My cake turned out beautifully and delicious. 100% gonna make again. Thank you for a wonderful recipe
I’m so glad you liked it, Kari!
Thank you for this recipe. I made this and it turned out great. For a different flavour, I took a heaped teaspoon of peanut butter and dotted bits of it into the batter. It turned out fabulous. I will make this again.
What a great mix-in idea! I’ll have to give it a try
That was way too much milk!
batter was way too wet. I followed directions exactly and I’m sure this has worked out for you but I would use 2-3 tbsp of milk if using this recipe.
Hi J, I just had my teenager test this out with the amounts called for and then I made one with less milk. The one with less milk was definitely dry after cooking while the one with the amounts called for in the recipe turned out light and perfect. I’m sorry you didn’t see the same results.
interesting substitutions! First I was too lazy to get the flour off the top shelf of the cupboard so I used whole wheat flower that was reachable. I used a little extra flour and baking powder. Then I knew I only had non fat milk but what I didn’t realize is that it had gone bad. My only alternative was chocolate almond milk! So I added a little extra butter to help and put some chocolate chips on top. It worked! Texture was a little off from the whole wheat flour but tasted great! will have to try again with proper ingredients ha!
I love that you weren’t afraid to experiment with ingredients, Linda! I’ll have to try the chocolate almond milk!
This didn’t take long to throw together in the mug. I made mine without sprinkles and it was delicious! I will definitely make this again.
So glad you liked it, Tiffany!
This is excellent cake! I used coconut oil because I have lots on hand, and heated it with the milk for 30 seconds so the cold milk didn’t harden it. I mixed the dry ingredients (I used coconut sugar) in a measuring cup and added them and the vanilla to the oil and milk and stirred them with a whisk. I microwaved the batter for 90 seconds, and it was perfect! It was a nice fluffy cake with lots of flavor and went beautifully with a glass of milk. I’ll make this again. Next time I’ll try stirring with a spoon to see if it affects the fluffiness that might have been due to mixing with a whisk, and tap the container on the counter to remove the air bubbles to see the difference in density. Thank you for this easy, quick, very enjoyable recipe!
It was basically all milk and it exploded everywhere in the microwave. Do you not test your recipes? There’s way too much milk for it to form a batter like it showed in the video.
Sorry it didn’t work out for you, Nick. Seems like there was an error in measuring when you were creating the batter. I’d love to help troubleshoot. Definitely have made this dozens of times with no issues, along with other users based on the ratings.
It’s such a simple and delicious recipe, I didn’t take more than 10 minutes making it!
Thanks for taking the time to leave a review, Reyna!
Did not work well I had to add lots of flour to get the right consistency and it needed salt
Hi Josie, I’d love to help figure this out. I’ve made this recipe over a dozen times and haven’t had any issues.
I was craving something sweet kinda late at night and didn’t have any desserts on hand. Made this super fast literally took 5 minutes! it was so good and i did substitute butter for oil and the consistency was perfect to me, nice and gooey, but i like that. Definitely will make this again!
good and yummy! as a child this is a really good recipe because i don’t have to use the oven. it’s very moist and yummy. It took longer than 5 minutes but that’s okay because i wasn’t expecting it to. For me it looks like mashed potato’s and has the texture of scrambled eggs. overall i give this a 4/5 and i would recommend this to people!
This came out perfect! Best mug cake recipe I’ve tried!
Thanks, Taylor!
I made this for my mom tonight. She was wanting something sweet and “bread like” but didn’t want a whole cake. So I gave this a go and it was a hit! She loved it! My dad and I also enjoyed a few bites. He and I are looking forward to trying the Chocolate and the cinnamon recipes!
This was my first time making a mug cake recipe. I chose this one because of the high number of positive reviews. It is as easy as it looks and the result was delicious. I recommend trying this one out.
Hi Andrea! Thank you so much for giving this recipe a try. I’m glad it worked out to give your mom that sweet fix!
Finally!! This is by far the best mug recipe I have found. Thank you!
This comment made my day! Thank you, Hope!
Genuinely the best mug cake i’ve ever had. Consistently too! I don’t use sprinkles because I’m not a sprinkles person, but I add cinnamon sugar and some homemade whip cream on top and its so good. 100% recommend.
Thank you, K! This is one of my personal favorites. I have a few other flavors you might like to try out. I’ve created 11 mug cake recipes so far, but more are on the way! My personal favorite is this one and the lemon cake.
I couldn’t find the amount of each ingredient?
Hi there. The ingredients are located in the recipe card at the bottom of the post.
I made this exactly as indicated. Only difference ( I didn’t have milk) so I used 1/4 cup of vanilla latte protein shake. I cooked in my microwave for 2 min exactly.
While that was cooking I mixed up some swerve powder sugar a small tab of butter and used more of the vanilla latte shake to whip up a frosting!!! It was absolutely delicious! Definitely took care of that late night sweet tooth without all the sweetness! Great recipe… now to experiment and explore the chocolate mix. ♥️
It turned out tasty, wasn’t the sweetest though. Didn’t look anything like the picture.
I made this and this could also be my fault but it came out like a bread instead any tips?
Hi Lexxi. I have a few things that could have gone wrong… Did you check the expiration date for the baking powder? If the leavening agent is expired it can cause the cake not to rise. The other thing that could have gone wrong is cooking for too long. Do you know what wattage your microwave is?
Absolutely delicious!! 😋🍰 I’ve tried so many different cake in a mug recipes and none of them tasted good. But this recipe, Omg, is freaking amazing! 😫❤️❤️❤️❤️Love eating it warm 🤤
Hi Ruby! I’m SO glad you love this recipe. It’s one of my favorite ways to sneak in a sweet treat
great recipe, easy, fast, yum
Glad you liked it!
Great recipe, 10/10 recommend! Super quick and easy, great for when you want something sweet after roasting to death in a school building for 7 hours! So easy, even an accident-prone high schooler can make it without issue! Thanks for the recipe, have a great day!
I’m SO glad you liked this recipe! My junior high kid loves it too and makes it regularly. Thank you for commenting!
It was so gross and oily
Hi Talia, I’ve made this recipe over 20 times and have never encountered that problem. Did you make substitutions? There’s no reason for this to be oily. It doesn’t call for oil?
Please add the amount of each ingredient, I tried it and my cake exploded.
You can find the measurements of each ingredient in the recipe card. If you’d looking for metric, it has those conversions as well. Simply click “metric” above the recipe ingredients.
Thank you, I tried it again, tastes really good! 😁
I’m so glad this worked out!
I’m not sure why, but mine turned out bitter with a weird texture. Could it have been because I used almond milk maybe? All other vanilla mug cake recipes also turn out like this.
Hi Lilli. I have almond milk in my fridge and went ahead and tested this theory. You’re correct. It did have a bitter finish. I did some digging and found that if a recipe involves baking soda or baking powder, almond milk produces a less satisfying rise and there’s a bitter aftertaste. It’s best to use a soy milk, or coconut milk if you are allergic to soy, for a less bitter and fluffier cake.
really easy to make and tasted great.
Thank you for the kind words, Maurina. This is a go-to for us when we need something sweet fast. I’m so glad you enjoyed it as well.
Tasty
Could you put cocoa in it for a chocolate cake?
Hi Carolyn, here is a chocolate mug cake recipe https://onesweetappetite.com/easy-chocolate-mug-cake/
I was craving dessert and gave this sprinkles mug cake a try for the first time. So delicious! So easy and perfect portion to fulfill my sweet tooth. The cake is delicious on its own but I topped it with frosting and more sprinkles. Will be keeping this recipe for many nights to come.
Hi Sarah! I’m glad you liked this as much as I do. It’s one of our favorites for when we need a sweet fix.
Hi
Cake was delicious but i have several different sizes of mugs
How big of mug approximately can i use
Also, how do i know when the cake is ready?
Do I test it like a regular cake — I know the cake continues to cook in the mug after removing it from the microwave
Thank you
Hi Meg, for this recipe I recommend using a 12oz mug or larger. As far as testing, you can do the classic cake test by poking with a toothpick right in the center. You will also be able to see the center start to fluff and look less wet. I hope this helps!
thanks so much for this freak’n mug cake amazing
I so tell every one of you to make this mug cake mmm
thanks so much Jes
