Ingredients
  

  • 1 scoop about 1/4 cup protein powder
  • 1 tbsp unsweetened cocoa powder
  • ¼ cup milk of choice adjust as needed
  • Optional toppings: 1 tsp peanut butter fresh berries, or chocolate chips

Instructions
 

  • In a small bowl, mix protein powder and cocoa powder until combined.
  • Add milk and stir to form a smooth, thick but pourable batter.
  • Lightly grease an 8oz mug or ramekin and pour in the batter.
  • Microwave for 45–60 seconds, depending on desired texture.
  • 45 seconds = gooier cake
  • 60 seconds = firmer cake
  • Let cool slightly before adding optional toppings like peanut butter or fruit.
  • Serve warm and enjoy your protein-packed dessert!

Notes

  • Protein powder: Whey protein gives the fluffiest results. Plant-based powders may need extra moisture (e.g., mashed banana or yogurt).
  • Customization: Try adding a dash of cinnamon, vanilla extract, or dark chocolate chips.
  • Allergy adjustments: Use dairy-free milk for a vegan-friendly option. Avoid peanut butter if nut allergies are present—swap for sunflower seed butter.
  • Serving tip: Best eaten warm, directly from the mug.
