Ingredients

Scale
  • ½ cup vanilla protein powder (whey or plant-based)

  • ¼ cup Greek yogurt or blended cottage cheese

  • ¼ cup self-rising flour or oat flour

  • 1 tbsp zero-calorie sweetener or coconut sugar (optional)

  • ½ tsp cinnamon

  • Pinch of salt

For the coating:

  • 1 tbsp melted coconut oil or almond milk

  • 2 tbsp sweetener + 1 tsp cinnamon

Instructions

  1. Mix the dough: Combine protein powder, yogurt, and flour in a bowl. Stir until a thick, slightly sticky dough forms.

  2. Shape: Roll the dough into 1-inch balls. If dry, add 1 teaspoon almond milk to adjust texture.

  3. Preheat air fryer: Set to 350°F (175°C) and lightly spray the basket.

  4. Air fry: Cook for 7–8 minutes, shaking halfway through, until golden and puffed.

  5. Coat: While still warm, brush with melted coconut oil or almond milk, then roll in the cinnamon-sweetener mix.

  6. Serve: Enjoy warm for the perfect mix of crisp outside and soft, cake-like inside.

Notes

  • Store leftovers in an airtight container for up to 5 days or freeze for 1 month.

  • Reheat for 20 seconds in the microwave or 2 minutes in the air fryer.

  • For extra flavor, mix in mini dark chocolate chips or drizzle with a light Greek yogurt glaze.

  • Use oat flour for extra fiber or almond flour for a low-carb version.
