Ingredients

Scale
  • 45 g (3 tablespoons) Greek yogurt, nonfat or full-fat
  • 30 g (1/3 cup) oat flour
  • 15 g (2 tablespoons) unsweetened cocoa powder
  • 1 tablespoon granular sweetener, such as erythritol or coconut sugar
  • 1/3 teaspoon baking powder
  • 1/4 teaspoon instant coffee or espresso powder (optional)
  • 30 ml (2 tablespoons) milk of choice
  • 1 pinch salt
  • 1–2 teaspoons chocolate chips, or to taste

Instructions

  1. Prepare the mug: Choose a microwave-safe mug with a capacity of at least 8–10 ounces to allow room for the brownie to rise.
  2. Mix the wet base: Add the Greek yogurt, granular sweetener, cocoa powder, optional coffee powder, and salt directly to the mug. Stir until smooth and creamy.
  3. Add the dry ingredients: Sift in the oat flour and baking powder. Pour in the milk and mix thoroughly until a smooth, thick batter forms without dry flour clumps.
  4. Add the chocolate chips: Sprinkle the chocolate chips over the batter and gently press a few into the surface for extra gooey chocolate pockets.
  5. Microwave the brownie: Cook on high power for 60–90 seconds, checking at the 60-second mark. Cooking time will vary depending on your microwave.
  6. Let it rest: Carefully remove the hot mug from the microwave and allow the brownie to rest for 1–2 minutes. The center will continue to set while remaining soft and fudgy.
  7. Serve and enjoy: Eat warm straight from the mug. Add fresh raspberries, a spoonful of almond butter, or a scoop of vanilla ice cream if desired.

Notes

  • Avoid overcooking: Start with 60 seconds in the microwave and add 10–15-second intervals as needed. The brownie should remain slightly moist in the center.
  • Make homemade oat flour: Blend rolled oats until finely ground if you don’t have oat flour.
  • Adjust the sweetness: Add more or less sweetener according to your taste and the sweetness of your chocolate chips.
  • Use your favorite yogurt: Nonfat Greek yogurt keeps the recipe lighter, while full-fat yogurt adds extra richness.
  • Try different toppings: Fresh berries, sliced banana, almond butter, chopped nuts, or vanilla yogurt make delicious additions.
  • Sweetener substitution: Replace the granular sweetener with 1 tablespoon of maple syrup, honey, or agave. Reduce the milk slightly if the batter becomes too thin.
  • Storage: This mug brownie tastes best freshly prepared. If necessary, cover and refrigerate leftovers for up to 1 day, then reheat briefly. The texture may become firmer.
  • Dietary options: Use dairy-free yogurt and plant-based milk for a dairy-free version. Choose certified gluten-free oat flour if gluten avoidance is necessary.
  • Microwave safety: Use only a microwave-safe mug and handle it carefully after cooking, as the mug and brownie can become very hot.
