Preheat oven to 350 degrees
Mix dry ingredients (protein powder, almond flour, cacao and baking powder) together in a bowl
Whisk wet ingredients (unsweetened almond milk, egg, and maple syrup) in a separate bowl. Add wet ingredients to dry and whisk until well blended.
Pour batter into a ramekin greased with a bit of avocado oil and top with chopped dark chocolate.
Bake in the oven for 15-20 minutes.
Remove and enjoy straight from the ramekin when cool.
If your protein powder is unsweetened, you may need to add some additional sweetener. For a softer, more creamy cake, bake for 15 minutes. For a firmer cake, bake for 20 minutes.
