Add the almond flour, cocoa powder, erythritol, and baking powder to a large bowl. Optionally, adjust the sweetener according to your taste. Mix well.
Step 2
Add the peanut butter and almond milk to a microwave-safe bowl. Microwave for 30 seconds. Remove from the microwave and mix well to combine the butter into the milk.
Step 3
Pour the peanut mixture into the bowl of dry ingredients, along with the vanilla extract. Stir well to combine. You should get a smooth cake batter. Stir in the chocolate chips.
Step 4
Grease four microwave-safe mugs or ramekins with coconut oil. Divide the batter evenly between the prepared mugs, and optionally, sprinkle each with some more chocolate chips. Microwave for 2 minutes or until set on top but still soft and gooey in the center.
Step 5
Remove from the oven and cool for a while. Optionally, serve with some vegan whipped cream or unsweetened chocolate sauce. Enjoy!
