I absolutely love chocolate and peanut butter.

Most of the dessert recipes on this blog involve those two ingredients and today I’m adding another one.

This recipe is a little different though, because it only makes one serving.

This Peanut Butter Chocolate Mug Cake is perfect for when you have a craving for something sweet but don’t trust yourself around an entire cake or whole batch of cookies.

Easy dessert recipe. Flourless peanut butter chocolate mug cake.

I started by combing peanut butter, brown sugar, salt, baking powder, vanilla, milk and an egg in a large coffee mug.

I stirred the ingredients until the mixture had a nice creamy consistency with no lumps.

Then I placed the chocolate chips on the top and microwaved it on high for one minute. 

I chose to make a flourless cake because I wanted it to be moist and gooey.

The result is a moist peanut butter cake filled with delicious melted chocolate.

Eat it while it’s warm to enjoy all it’s ooey gooeyness!
