Ingredients for This Protein Mug Cake Recipe

One of the reasons I love this protein mug cake recipe is how simple it is. You don’t need fancy equipment or complicated steps—just a mug, a spoon, and a microwave. Here’s what I use every time:

  • 1 scoop protein powder (about 1/4 cup) – the star of this recipe and your main protein source.
  • 1 tbsp unsweetened cocoa powder – adds rich chocolate flavor without the extra sugar.
  • 1/4 cup milk of choice – adjust as needed depending on the type of protein powder you use.
  • Optional toppings: 1 tsp peanut butter, fresh berries, or a few chocolate chips for extra indulgence.

Step-by-Step Preparation

Follow these easy steps, and you’ll have a warm, soft, and fluffy protein mug cake recipe ready in no time:

  1. Mix the dry ingredients. Combine protein powder and cocoa powder in a small bowl until well blended.
  2. Add milk. Pour in your milk of choice and stir until a smooth batter forms. The consistency should be thick but pourable.
  3. Pour into a mug. Lightly grease an 8-oz mug or ramekin, then transfer the batter inside.
  4. Microwave. Cook on high for 45–60 seconds. For a gooey cake, stop at 45 seconds; for a firmer texture, go closer to 60 seconds.
  5. Cool slightly. Let it rest for 1–2 minutes before topping with peanut butter, berries, or chocolate chips.
  6. Serve warm. Grab a spoon and enjoy your freshly made protein mug cake recipe straight from the mug.

 Pro Tip: If you’re using a plant-based protein, you may need to add a spoon of mashed banana or yogurt to keep the mug cake soft and moist.

This easy protein mug cake recipe is proof that healthy eating doesn’t need to be complicated—you can fuel your body and satisfy your cravings in under 5 minutes.
