How to make keto mug brownie?

A mug brownie is a fudgy brownie baked in your microwave. If you don’t have a microwave you can always bake this recipe at 180C (370F) for 10-15 minutes in an oven-safe ramekin. The ingredients you need to make this keto mug brownie are the basics keto ingredients listed below:

  • Coconut flour – yes, you need a tiny bit of coconut flour, 2 teaspoons (not tablespoons!) It is a very high-fiber flour and this amount is enough to create a fudgy brownie batter.
  • Unsweetened cocoa powder
  • Erythritol – or a sugar-free sweetener of your choice, use our sweetener converter to chose.
  • Melted coconut oil
  • Unsweetened coconut milk or almond milk

How to serve this keto brownie in a mug?

A mug brownie is piping hot after 60 seconds baking in the microwave. That’s why it’s very important to first let it cool down for 1 or 2 minutes, in the mug. This cooling time will also enhance the fudgy texture of the brownie and create the particular brownie ‘crust’ that we all love in a brownie. You should then eat the brownie in the mug, don’t transfer onto a plate or it would be very messy. Then you can add some toppings. The best keto brownie toppings to serve with this mug brownie are:

  • Unsweetened whipped cream – you can use coconut cream if dairy-free or vegan.
  • Sugar-free chocolate chips – add few more sugar-free chocolate chips on the hot brownie, they will melt and add a touch of sweetness!
  • Sugar-free vanilla ice cream – a scoop of keto ice cream will be delicious on top of this.

  • In a small bowl or directly in your mug add all the ingredients except the chocolate chips - if used. 
  • Combine with a fork or a small whisk until the batter is consistent and shiny.
  • Sprinkle extra chocolate chips on top if you like. I used stevia-sweetened dark chocolate chips.
  • Microwave on high 900W, for 60 seconds for a fudgy brownie or 70-80 seconds for a less fudgy texture.
  • Cool down for 1 minute before eating. This will allow the brownie to cool down a bit and the texture to be perfectly fudgy.
  • Serve with few extra sugar-free chocolate chips or unsweetened whipped cream.
