Ingredients
  

  • 1 scoop (about 25–30 g) chocolate or vanilla whey or plant-based protein powder
  • 2 tablespoons almond flour (or coconut flour; see notes)
  • 1 tablespoon unsweetened cocoa powder (omit if using vanilla protein and want a non-chocolate cake)
  • 1/2 teaspoon baking powder
  • 1–2 tablespoons granulated zero-calorie sweetener (like erythritol, allulose, or a blend), to taste
  • 1 large egg (room temperature if possible)
  • 2–3 tablespoons unsweetened almond milk (or water; start with 2 and add more if needed)
  • 1 teaspoon neutral oil or melted butter (adds moisture)
  • 1/2 teaspoon vanilla extract (optional if using vanilla protein)
  • Pinch of salt
  • Optional mix-ins: 1 tablespoon no-sugar-added chocolate chips, a few berries, or a teaspoon of peanut butter

Method
 

  1. Choose the right mug: Use a microwave-safe mug that holds at least 12 ounces. This gives the cake room to rise without spilling.
  2. Mix dry ingredients: In the mug, whisk protein powder, almond flour, cocoa powder, baking powder, sweetener, and salt until no clumps remain.
  3. Add wet ingredients: Crack in the egg, pour in 2 tablespoons almond milk, add oil and vanilla. Stir well until a smooth batter forms. If it’s very thick, add the extra tablespoon of milk. The batter should be like thick pancake batter.
  4. Customize: Fold in chocolate chips, berries, or a small dollop of nut butter if using. Keep mix-ins to 1–2 tablespoons total so the cake stays fluffy.
  5. Microwave: Cook on high for 45–60 seconds, then check. If the center is still glossy or jiggly, continue in 10–15 second bursts. Total time is usually 60–90 seconds depending on your microwave.
  6. Rest and enjoy: Let the mug cake sit for 1 minute. This helps it set and keeps it moist. Top with a spoon of Greek yogurt, a few berries, or a sprinkle of cocoa if you like.
