Ingredients You’ll Need
So I have you hooked and you’re ready to know the ingredients, right? Here is what you will need to get started:
- 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.

- Prepare the Mug: Lightly spray the inside of a microwave safe 12-ounce mug with baking spray to prevent sticking.

Helpful FAQs
A 12 to 15-ounce microwave-safe mug is ideal. It allows enough space for the cake to rise without spilling over.
A rubbery texture often results from overcooking. Try reducing the microwave time by 10-20 seconds, or check your microwave’s wattage and adjust accordingly.
I don’t recommend baking this recipe. If you’re looking for a baked cake I suggest following the instructions on the back of the box for a full cake and freezing slices for later.
The top should look set and dry. If it’s still gooey, microwave it in 10-second bursts until it’s done. Be careful not to overcook, as the cake continues to cook slightly from residual heat after it’s removed from the microwave.
