This brown butter banana snack cake is soft, rich, and deeply flavorful—thanks to the magic of caramelized bananas and nutty brown butter. It’s the kind of cozy, crowd-pleasing treat that’s equally perfect for breakfast, dessert, or an afternoon pick-me-up.
½ cup unsalted butter
1 cup mashed ripe bananas (about 2–3 bananas)
½ cup brown sugar
¼ cup white sugar
2 eggs
½ cup Greek yogurt or sour cream
1½ cups all-purpose flour
1 tsp baking soda
½ tsp cinnamon
¼ tsp salt
Optional: chopped walnuts, mini chocolate chips, or a dusting of powdered sugar
Preheat oven to 350°F (175°C). Grease or line an 8×8-inch pan.
In a saucepan, melt butter over medium heat, stirring until it foams and turns golden brown with a nutty aroma. Remove from heat and let cool slightly.
In a bowl, whisk together brown butter, mashed bananas, sugars, eggs, and yogurt until smooth.
Stir in flour, baking soda, cinnamon, and salt until just combined.
Fold in mix-ins if using. Pour batter into prepared pan.
Bake for 30–35 minutes or until a toothpick comes out clean. Cool before slicing.
