Ingredients Equipment Method Notes

Ingredients
  

  • 1 scoop chocolate protein powder (whey or plant-based)
  • 1 tbsp cocoa powder
  • 2 tbsp almond flour (or oat flour)
  • 0.5 tsp baking powder
  • 1 tbsp maple syrup (or honey)
  • 0.25 cup almond milk (or any milk)
  • 1 tbsp peanut butter or almond butter (optional, for center)
  • 1 pinch salt

Equipment

  • microwave-safe mug
  • whisk or fork
  • microwave
  • spoon

Method
 

  1. In a microwave-safe mug, whisk together the dry ingredients: protein powder, cocoa powder, almond flour, baking powder, and salt.
  2. Add almond milk and maple syrup. Stir until smooth.
  3. If using nut butter, drop it into the center of the batter — don’t mix.
  4. Microwave on high for 60–75 seconds. The top should look set but still soft.
  5. Let it cool for 1–2 minutes. Dig in with a spoon or top with Greek yogurt, berries, or a few dark chocolate chips.

Notes

Optional toppings: Greek yogurt, berries, or dark chocolate chips. For a richer flavor, add a splash of vanilla extract. If using unflavored protein powder, increase cocoa by 1 tsp and sweetener slightly. For gooey texture, reduce cook time by 10 seconds.
