Ingredients You’ll Need
- Cake Mix: Pick your favorite brand for this cake mix mug cake. I will mention that we did not test this with gluten free options or keto, so I cannot be sure if those will work well.
- Water: Water is essential in cake mixes as it hydrates the dry ingredients, activates gluten and leavening agents for structure and rise, and helps achieve the right batter consistency. We did test this with milk but it didn’t produce the same light and moist texture.
- Oil: Add testing this mug cake with both oil and butter to our list. We tried them both and were shocked when oil won out in the blind taste test. The cakes made with oil were lighter and had a more enjoyable texture.
- Sprinkles: When it comes to sprinkles, I recommend using Jimmies. They are the longer colorful variety vs the small bead type. They won’t bleed the color out into the cake.
How To Make A Cake Mix Mug Cake
Ready to get rolling? Here’s the broken down step by step to make your first mug cake!
- Prepare the Mug: Lightly spray the inside of a microwave safe 12-ounce mug with baking spray to prevent sticking.
- Mix Ingredients: Pour the cake mix, water, and oil into the mug. Use a fork to stir everything together until well combined. Add the sprinkles and give just a light mix.
- Microwave the Cake: Cook in the microwave for about 1 minute and 15 seconds. Check if the cake is done—it should look set and dry on top. Note: Cooking time can vary based on your microwave’s power, so it might need slightly less or more time.
- Cool and Enjoy: After microwaving, let the cake stand in the mug for one minute to cool slightly. Then it’s ready to enjoy!

Expert Recipe Tips
Mug cakes are so simple to make but there are a few tips to make these turn out perfect every single time!
- Use Fresh Ingredients: Ensure your baking powder is fresh for the cake to rise properly.
- Mix Thoroughly: Whisk the ingredients well to avoid any lumps and ensure a smooth batter.
- Microwave Power: Cooking times may vary depending on your microwave’s wattage. Start with 1 minute and check, adding 10-15 seconds if needed.
- Watch Closely: Keep an eye on the cake as it cooks to prevent overbaking, which can lead to a dry texture.
- Rest After Cooking: Let the cake sit for a minute or two after microwaving to finish cooking and set properly.
Recipe FAQs
Yes, you can use any flavor of cake mix. Just follow the same basic proportions and instructions.
Insert a toothpick into the center of the cake. If it comes out clean or with a few moist crumbs, the cake is done. The top should also be firm to the touch.
Overcooking can cause dryness. Adjust the microwave time and try reducing it by 10-15 seconds if the cake is too dry.
Mug cakes are best enjoyed fresh, but you can cover and refrigerate leftovers for up to 1 day. Reheat gently in the microwave before eating.
A 12 to 15-ounce microwave-safe mug is ideal. It allows enough space for the cake to rise without spilling over.
