Servings 1 servings

Ingredients
  

  • 1 small egg (or 3 tablespoons liquid egg whites)
  • 2 tablespoons unsweetened applesauce
  • 1 tablespoon milk (dairy or almond/oat milk)
  • 1 tablespoon maple syrup (or honey, or sugar substitute to taste)
  • 1/2 teaspoon vanilla extract
  • 2 tablespoons almond flour
  • 2 tablespoons oat flour (use certified gluten-free; or blitz oats in a blender)
  • 1 scoop (about 20–30 g) vanilla or unflavored whey or plant protein
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon baking powder (gluten free)
  • Pinch of salt
  • 2 tablespoons finely diced apple (peeled if you like)
  • 1 teaspoon butter or coconut oil (melted; optional but recommended for moisture)
  • Optional toppings: extra cinnamon, a drizzle of maple, Greek yogurt, or a few chopped nuts

Instructions
 

  • Prep your mug: Use a large microwave-safe mug and lightly grease it to prevent sticking.
  • Whisk wet ingredients: Add egg, applesauce, milk, maple syrup, vanilla, and melted butter/oil. Whisk with a fork until smooth.
  • Add dry ingredients: Stir in almond flour, oat flour, protein powder, cinnamon, baking powder, and salt. Mix until just combined.
  • Fold in apple: Gently stir in the diced apple so it’s evenly distributed.
  • Microwave: Cook on high for 60–90 seconds. Start checking at 60 seconds. The top should look set but still moist. Avoid overcooking.
  • Rest: Let it stand for 30–60 seconds to finish steaming and become fluffy.
  • Top and enjoy: Add a sprinkle of cinnamon, a spoon of Greek yogurt, or a drizzle of maple. Serve warm.
