Protein Banana Mug Cake (Print Version)

Protein-packed banana mug cake ready in five minutes—ideal for quick breakfasts or snacks.

# What You’ll Need:

→ Wet Ingredients

01 - 1 medium ripe banana, mashed
02 - 1 large egg

→ Dry Ingredients

03 - 1 scoop (about 30 g) vanilla or unflavored protein powder
04 - 1/4 tsp baking powder (optional, for fluffiness)

→ Optional Additions

05 - 1/2 tsp cinnamon
06 - 1 tsp honey or maple syrup (for extra sweetness)
07 - 1 tbsp chopped nuts or chocolate chips

# How to Make It:

01 - In a large microwave-safe mug, mash the banana with a fork until smooth.
02 - Crack in the egg and whisk together until fully combined.
03 - Add the protein powder and baking powder (and any optional additions). Mix until smooth and no lumps remain.
04 - Microwave on high for 1 minute 30 seconds to 2 minutes, or until the cake has set and risen.
05 - Let cool for 1 minute before eating. Enjoy directly from the mug.

# Additional Tips::

01 -
  • You can make it faster than your coffee brews and no one has to know it’s secretly packed with protein.
  • It uses up spotty bananas and gives you an excuse to eat cake for breakfast guilt-free.
02 -
  • Filling the mug more than half full is risky—I learned the hard way with a lava-like overflow all over the microwave tray.
  • A little splash of milk makes the cake softer and less rubbery, especially if using whey protein powder.
03 -
  • If your mug cake came out dry, try covering the mug loosely with a saucer when microwaving to trap in steam.
  • A dash of cinnamon delivers more than flavor—it also masks any strong protein powder aftertaste.
