This peanut butter cookie mug cake is all things delicious.

While I wouldn’t stretch and call this healthy, it is gluten free, dairy free, and refined sugar free.

In my book that makes for a much healthier indulgence than something packed full of super processed ingredients with excessive sugar.

After the huge hit that was my Gluten Free Chocolate Mug Cake, I wanted to play around some and create more mug cakes!

Mug cakes are so fun to make and only take around 5 minutes.

First, melt peanut butter in a large microwave safe mug for 30 seconds.

This will make it easier to mix with the other ingredients.

Add the applesauce, maple syrup, oat flour, coconut flour, rolled oats, baking powder, egg, vanilla, salt, and almond milk to the mug.

Stir well with a fork until totally combined.

Microwave for 2 – 4 minutes, in 30 second increments, until the top is no longer squishy.

The cook time will vary based on the size of your mug, as this is one big peanut butter cookie cake!

It’s so big in fact that I always split it with my husband and it is still a generous portion.

This recipe is made using healthier ingredients, but it’s definitely an indulgence.

I love serving mine drizzled with chocolate sauce and topped with a scoop of ice cream.

If you want to keep it dairy free, simply use your favorite dairy free chocolate sauce and ice cream!

I love dessert, so if I’m going to treat myself, I use healthier substitutions.

This dessert is so rich and decadent and worth every single bite.

It took me 3 tries to get this recipe just right.

The first time it was a bit too dry, but the flavor was still awesome and we ate it with ice cream.

The second time it was not quite cake-y enough.

The third time I finally got it right! This cake tastes like a rich peanut butter cookie.

I have made it many times since then and it comes out delicious every time!

Not only is it delicious, but it’s also gluten free, dairy free, and refined sugar free!

The last time we ate this, I drizzled some dairy free chocolate syrup on top and enjoyed it with almond milk vanilla ice cream.

It was insanely good, like eating a healthy reese’s cake almost.

    This is my second time making this amazing mug cake. I now wish I had never tried it because it is so dang delicious! After many recipe fails via Pinterest, I am happy to have one that actually works.

  2. Hi,

    Do you think I could substitute the egg with a vegan egg ( 1 T ground flaxseed, 3T water). This sounds amazing!!!

    1. Hi Heidi,

      I’ve used vegan eggs before and they usually turn out good. While I haven’t tried it myself, I think it would work. Let me know if you try it!

  3. This sounds so yummy! Is there anyway of making this cake flourless?? (Like, could I make this cake just using oats?)
