Equipment

  • Microwave-safe mug
  • Small mixing bowl
  • Spoon or fork
  • Measuring spoons

Ingredients
  

  • 1 small apple (Granny Smith, Honeycrisp, or Fuji), diced
  • ½ tsp cinnamon
  • 1 tsp sweetener (honey, maple syrup, or stevia)
  • 1 tsp lemon juice (optional, for brightness)
  • 2 tbsp rolled oats (gluten-free if needed)
  • 1 tbsp protein powder (whey, plant-based, or casein)
  • 1 tsp butter or coconut oil
  • Pinch of salt
  • Optional toppings: Greek yogurt, nuts, caramel drizzle

Instructions
 

  • Prepare apples: Dice apple into small cubes. Toss with cinnamon, sweetener, and lemon juice. Place in microwave-safe mug.
  • Mix topping: In a small bowl, combine oats, protein powder, butter/oil, and salt. Mix until crumbly.
  • Layer: Spoon topping evenly over apples in the mug.
  • Microwave: Cook on high for 2–3 minutes until apples are tender and topping is bubbly.
  • Cool slightly: Let sit for 2 minutes before eating to allow flavors to meld.
  • Serve: Enjoy warm, topped with Greek yogurt, nuts, or caramel drizzle if desired.

Notes

  • Apple choice: Granny Smith adds tartness; Honeycrisp or Fuji bring sweetness.
  • Protein tip: Balance powder with moisture (butter, oil, or yogurt) to avoid dryness.
  • Variations: Add peanut butter for richness, chocolate protein powder for indulgence, or almond flour for gluten-free adaptation.
  • Storage: Best enjoyed fresh, but can refrigerate for up to 2 days. Reheat gently in microwave with splash of milk to restore texture.
  • Serving suggestion: Pair with Greek yogurt for extra protein or a scoop of ice cream for indulgence.
