Cut the banana and put it on a plate.
Use a fork to smash the banana into small pieces.
First, mix the dry ingredients: the granulated sugar, cocoa powder, and baking powder in the mixing bowl with the smashed banana. Mix well to ensure even distribution. Then, add the white yogurt, vegetable oil, and vanilla extract to the bowl. Stir until the batter is smooth and well combined.
Gently fold in the blueberries, raspberries, and chopped almonds into the batter. Mix lightly to ensure they are evenly distributed. Add 4-5 slices of banana to the mixture for an extra banana flavor. Refrigerate the mug cake for at least 1-2 hours to allow it to set. Once set, you can enjoy it straight from the mug or tip it out onto a plate if you prefer
