In a small microwave-safe ramekin, combine the protein powder, cocoa powder, baking powder, and sweetener.

Add the almond milk and applesauce to the dry ingredients and stir until a smooth batter is formed.

Gently press the dark chocolate square into the center of the batter until it is fully submerged.

Microwave on high for 50 seconds or until the sides are firm but the center remains slightly soft to the touch.

Remove from the microwave and let sit for 60 seconds to allow the residual heat to finish the internal cooking process.
