Ingredients
Quantities are shown as originally provided.
- 1/4 cup Mashed Banana (equivalent 1 small banana)
- 3 tablespoons Unsweetened Almond Milk (or any dairy-free milk )
- 3 tablespoons Homemade Oat Flour
- 2 tablespoons Vanilla Protein Powder
- 1-2 tablespoons Crystal Sweetener of Choice (I used sugar-free erythritol or coconut sugar)
- 1/2 teaspoon Baking Powder
- 2 teaspoons Dairy-Free Dark Chocolate Chips (optional)
Instructions
- 1
In a microwave-safe coffee mug (minimum size 1 cup/250ml) stir together mashed banana and almond milk.

Whisk together the dry ingredients: oat flour, protein powder, sweetener, and baking powder. Set aside.
- 3

Sprinkle a few extra chocolate chips on top if desired.
- 5
Microwave on high power (800W) for about 90 seconds or stop the microwave 10 seconds after you see the cake rising to its maximum height. Remove from the microwave carefully, it is hot! Check the texture. It should be moist and soft and the top should deflate. If it is not cooked to your liking after that time, return to the microwave and cook again by 10-second bursts until done - no more than 90 seconds in total. Note that the longer you microwave the mug cake, the denser it will be.
