3 Ingredient Flourless Peanut Butter Mug Cake

This easy flourless peanut butter mug cake is only three ingredients.

Just like how easy this mug cake is, I’m going to keep this post simple and sweet.

I’m quite tired. In the past 2 weeks, I’ve traveled out of town three times. And while I’m grateful for all the experiences, I’m also exhausted. I’m looking forward to being in my own home for an extended period of time and going back to my normal routine and back to my regular blogging schedule.

But even in my exhausted state, I can make this five minute mug cake. And you can too.

I recently started playing around with making videos. It’s definitely a learning experience so I know this isn’t my best work, but here’s a quick little video showing me making this recipe (on another occasion, so it’s not the same cake as in the photos).

I actually already have a flourless peanut butter mug cake recipe I really love. But I was playing around in the kitchen the other day and discovered I could create one with just three ingredients.

This cake is peanut buttery, but also light and fluffy. You won’t believe it’s flourless. If you have peanut butter, eggs, and sugar, I urge you to try it now.
