Ingredients
  

  • Protein powder: Whey or a whey-casein blend works best; vanilla or unflavored.
  • Almond flour: Finely ground, blanched for best texture.
  • Coconut flour (optional): A small amount adds structure.
  • Baking powder: For lift.
  • Sweetener: Granulated erythritol, allulose, or a stevia blend.
  • Salt: Just a pinch.
  • Egg white: From a fresh egg or carton.
  • Plain Greek yogurt: 2% or nonfat.
  • Unsweetened almond milk: Or another low-carb milk.
  • Vanilla extract: For flavor.
  • Sugar-free chocolate chips: Or 85–90% dark chocolate chopped finely.
  • Optional add-ins: Cinnamon, espresso powder, or a pinch of xanthan gum for extra structure.

Method
 

  1. Choose the right mug. Pick a microwave-safe mug that holds at least 12 ounces. A wider mug helps the cake cook evenly.
  2. Mix the dry ingredients. In the mug, whisk 1 scoop (about 30 g) protein powder, 2 tablespoons almond flour, 1 teaspoon coconut flour (optional), 1/2 teaspoon baking powder, 1–2 tablespoons sweetener (to taste), and a pinch of salt.
  3. Blend the wet ingredients. Add 2 tablespoons plain Greek yogurt, 2 tablespoons egg white, 2 tablespoons unsweetened almond milk, and 1/2 teaspoon vanilla extract. Stir until smooth. The batter should be thick but scoopable—like brownie batter. If it’s dry, add 1 teaspoon more milk at a time.
  4. Fold in chocolate chips. Stir in 1–1.5 tablespoons sugar-free chocolate chips. Reserve a few to sprinkle on top for a melty finish.
  5. Microwave carefully. Microwave on medium-high (about 70–80% power) for 45–60 seconds. Check the center; it should be mostly set with a soft, slightly glossy top. If needed, continue in 10–15 second bursts. Avoid overcooking—protein cakes can turn rubbery fast.
  6. Rest briefly. Let the cake sit for 30–60 seconds. This helps it finish cooking and keeps it moist.
  7. Top and enjoy. Add a few extra chips, a drizzle of almond butter, or a spoon of Greek yogurt. Eat warm for the best texture.
