Banana bread in a mug? How easy is that? I love banana bread!!! The smell of it baking in the oven instantly makes me think of my sweet mama. This single-serving recipe is great for when you don’t want to commit to baking an entire loaf of banana bread and helps you portion control. To keep the texture moist, this recipe calls for a ripe banana instead of added oil or sugar. The almond flour acts as a base and creates that craveable, bread-like texture.
