Method

  1. Gather all ingredients and a microwave‑safe mug or small bowl.

  2. Peel the banana and slice it into chunks for easier blending.

  3. Place the banana, cocoa powder, egg, and baking powder into a blender.

  4. Blend on high speed until the mixture is completely smooth, about 20‑30 seconds.

    Kitchen notes · Added by ReelsMeals: The batter is smooth with no visible banana pieces.

  5. If you like extra texture, stir a handful of chocolate chips into the batter with a spoon.

  6. Lightly grease the microwave‑safe container with a tiny amount of oil or butter to prevent sticking.

  7. Pour the batter into the prepared container, smoothing the top with the back of a spoon.

  8. Microwave on high (approximately 900 W) for 2 minutes. Do not open the microwave during cooking.

    Kitchen notes · Added by ReelsMeals: The brownie sets around the edges while a few moist crumbs may cling to a tester.

  9. Check for doneness by inserting a toothpick; it should come out with a few moist crumbs, not wet batter. If needed, microwave in 15‑second bursts.

  10. Allow the brownie to rest for 1‑2 minutes; it will continue to set as it cools.

    Kitchen notes · Added by ReelsMeals: Resting lets the brownie continue to set.

  11. Optionally, dust with a pinch of powdered sugar or drizzle with a quick chocolate sauce before serving.
