Ingredients Method

Ingredients
  

  • 1 scoop (25–30 g) vanilla or cinnamon protein powder (whey or a whey/casein blend works best; plant-based also works with tweaks)
  • 2 tablespoons almond flour (adds moisture and structure while keeping carbs low)
  • 1 tablespoon coconut flour (for fluff and fiber; can sub with more almond flour, see notes)
  • 1/2 teaspoon ground cinnamon (or 3/4 teaspoon if you love it)
  • 1/2 teaspoon baking powder
  • Pinch of salt
  • 1 large egg
  • 2 tablespoons plain Greek yogurt (or dairy-free yogurt)
  • 2–3 tablespoons unsweetened almond milk (or milk of choice)
  • 1–2 teaspoons granular or liquid low-carb sweetener (erythritol, allulose, stevia blend; adjust to taste)
  • 1/2 teaspoon vanilla extract
  • Optional toppings: a sprinkle of cinnamon, a drizzle of sugar-free maple syrup, a dollop of Greek yogurt, or a quick cream cheese “frosting” (see Variations)

Method
 

  1. Choose the right mug: Use a large microwave-safe mug (at least 12 ounces). The batter will rise as it cooks.
  2. Mix dry ingredients: In the mug, whisk protein powder, almond flour, coconut flour, cinnamon, baking powder, and a pinch of salt. Break up any clumps for a smooth batter.
  3. Add wet ingredients: Crack in the egg. Add Greek yogurt, almond milk, sweetener, and vanilla. Stir until fully combined. The batter should be thick but spoonable. If it’s too thick, add 1 teaspoon of milk at a time.
  4. Taste and adjust: If you prefer sweeter, add a bit more sweetener. If you love spice, add a pinch more cinnamon.
  5. Microwave in bursts: Microwave on high for 40–50 seconds. Check the center, then continue in 10–15 second bursts until the top is set but still slightly springy. Total time is usually 60–90 seconds, depending on your microwave.
  6. Rest briefly: Let the cake sit for 1 minute. It finishes steaming and becomes more tender.
  7. Top it: Add a sprinkle of cinnamon, a drizzle of sugar-free syrup, or a spoon of Greek yogurt. Enjoy warm.
