Peanut Butter Banana Mug Cake: Stir in 1 tablespoon of peanut butter into the batter for a creamy, nutty flavor. You can also add a spoonful on top once the cake is cooked for a richer taste.
Nutty Banana Mug Cake: Stir in 1 tablespoon of chopped nuts like walnuts or almonds for added crunch and texture. This pairs wonderfully with the soft, moist cake.
Caramel Banana Mug Cake: Drizzle a little caramel sauce over the top of the cooked mug cake. You can even mix a teaspoon of caramel into the batter for a sweet, gooey interior.
