Ingredients and substitutions

Banana. We just need half a banana for this recipe. The riper the banana, the better! Once you mash it, it’ll end up being about 2 tablespoons of mashed banana.

Egg. Just one! I haven’t tested this recipe with an egg replacer so if you do any experimenting with an egg-free option, let me know how it goes!

Coconut Sugar. I’ve tried this with a sticky sweetener (agave nectar) and have found granular sweetener works best. My favorite is coconut sugar, but another granular sweetener should probably work.

Almond Flour. I always go with blanched almond flour and haven’t tested it with other flours so let me know in the comments if you do any experimenting!

Baking Powder. For some fluff!

Chocolate Chips. You can really customize whatever you want to fold into this mug cake. Walnuts or peanut butter chips would be delish!

How to make this 3-Minute Cake:

It’s so simple and you make it all in your mug! Mash the banana in your mug. Use a small whisk to whisk in the egg and coconut sugar.

Then, add the almond flour and baking powder. Whisk again until combined.

Fold in the chocolate chips, sprinkle some more on top and then microwave. I microwaved mine for 1 minute and 30 seconds. This made for a light and fluffy yet moist and tender mug cake.

Recipe Success Tips

Mix well: Thoroughly mix all the ingredients to ensure that the batter is well combined and free of clumps.
Microwave for the right time: Keep an eye on it and stop the microwave when the cake has risen and is set in the middle. Overcooking can lead to a dry, tough cake.
Experiment with flavors: Feel free to add different flavors to your mug cake such as cocoa powder, spices, or even a teaspoon of instant coffee. Get creative and have fun with it!
