4 Ingredient Flourless Chocolate Peanut Butter Mug Cake
This easy mug cake is just four ingredients. It’s soft and fluffy like a traditional cake even though it doesn’t have any flour or baking powder!
Last year I shared my 3 Ingredient Flourless Peanut Butter Mug Cake recipe. I’ve received so much positive feedback that always put a smile on my face. Sometimes, people share other things they add to it and it’s always fun to hear the variations. Several people mentioned adding chocolate chips, which gave me the idea to try doing a chocolate version.
With just four ingredients, you can have a chocolate peanut buttery treat in just minutes. I also drizzled my with some chocolate fudge to dress up the cake a little.
4 Ingredient Chocolate Peanut Butter Mug Cake
- 3 tbsp creamy peanut butter (I recommend sticking to a regular processed peanut butter rather than using natural and/or unsweetened)
- 1 large egg
- 1/2 tbsp unsweetened dutch processed cocoa powder
- 2 tbsp granulated white sugar
Add all ingredients into an oversized, microwave-safe mug (the one in the photo is a 10 oz mug). Using a mini whisk, mix batter until it is smooth and egg is fully whisked in. I highly recommend using a whisk so that you can easily beat the egg fully into the batter. Microwave for about 1 minute. Let cake cool a few minutes before eating. The cake itself is not overly sweet so if you prefer something sweeter, I recommend you drizzle some chocolate sauce on top before eating.
