Butter your favorite mug and pour the mixture. Place it in your microwave for 2-4 minutes (depending on the power of your microwave) or until your skewer comes out pretty clean. Mine took 3 minutes to be perfectly cooked.

When it’s ready, it should come out of your mug quickly. You can serve it directly from your cup, but I prefer to put mine on a plate and serve it with some dark chocolate, cinnamon and sometimes topped with coconut oil or peanut butter.

As you can see the consistency, it’s similar to the real chocolate brownie. Trust me, you’ll feel like eating the real thing. This is one of the recipes that I’m making almost every day. Sometimes I don’t even add sweetener because I like the bitter taste too. I love that the coconut flour absorbs the liquids well and it won’t be wet and eggy.

Imagine eating this keto mug cake with fresh whipped cream on top or with vanilla keto ice cream. Sounds divine? Make it now and serve it with a delicious keto coffee.
