This Protein Mug Cake is a quick, easy, and delicious single-serving dessert packed with protein. Perfect for a healthy snack or a guilt-free treat, it combines protein powder, almond flour, and cocoa powder into a fluffy cake ready in just minutes using the microwave.

Ingredients

Dry Ingredients

  • 1 scoop protein powder (chocolate or vanilla)
  • 1 tbsp almond flour (or oat/all-purpose flour)
  • 1 tbsp cocoa powder
  • ½ tsp baking powder

Wet Ingredients

  • ½ cup almond milk (or milk of choice)
  • Optional: 1 tbsp Greek yogurt for extra fluffiness

Toppings (Optional)

  • Peanut butter
  • Greek yogurt
  • Berries

Instructions

  1. Grab a Big Mug: Choose a microwave-safe mug with at least 12 oz capacity to ensure the cake can rise without spilling over.
  2. Mix Dry Ingredients: Add the protein powder, almond flour, cocoa powder, and baking powder into the mug. Stir thoroughly to combine all dry ingredients evenly.
  3. Add Liquid: Pour in the almond milk and, if using, the Greek yogurt. Stir well until the batter is smooth and free of lumps.
  4. Microwave Magic: Microwave on high power for 60 seconds. Check the top – if it’s not set, continue microwaving in 10-second increments until the cake is just firm to the touch.
  5. Rest & Serve: Allow the mug cake to rest for 1–2 minutes in the microwave or on a heat-safe surface. Then add your choice of toppings such as peanut butter, Greek yogurt, or fresh berries and enjoy immediately.

Notes

  • Use a microwave-safe mug of sufficient size to prevent overflow during cooking.
  • Protein powder flavor choice can be adjusted based on preference (chocolate or vanilla works best).
  • Substitute almond flour with oat flour or all-purpose flour if needed, though texture may vary slightly.
  • Adding Greek yogurt enhances moisture and fluffiness but is optional.
  • Cooking times may vary depending on microwave wattage; watch the cake carefully to avoid overcooking.
  • For a vegan option, use plant-based protein powder and yogurt alternatives.
