Equipment
Ingredients
Cake
- 5 tbsp unsalted butter, melted
- ⅓ cup light or dark brown sugar, lightly packed
- 2 large eggs
- 1 tsp vanilla extract
- 1 cup mashed bananas, from 2-3 very ripe bananas
- 1 ⅓ cups all-purpose flour, fluffed, spooned and leveled
- 1 ½ tsp baking powder
- ¼ tsp baking soda
- ¼ tsp coarse Kosher salt (if using table salt, use half the amount)
- ½ tsp ground cinnamon
- ¼ tsp ground nutmeg
Topping
- 1 ½ cups all-purpose flour, fluffed, spooned and leveled

- ⅓ cup light or dark brown sugar, lightly packed
- ½ tsp ground cinnamon
- ¼ tsp ground nutmeg
- ¼ tsp coarse Kosher salt (if using table salt, use half the amount)

Instructions
Cake
- Preheat the oven to 350 F, and position a rack in the center of the oven. Spray a 9×9 inch baking pan with non-stick spray, or coat the pan with butter and flour to keep the cake from sticking.
- In a large mixing bowl, whisk together the melted butter, brown sugar, eggs, vanilla and mashed bananas.
- Separately, sift together the flour, baking powder, baking soda, salt, cinnamon and nutmeg. Add the dry ingredients to the wet, and stir together with a spatula, just until moistened. The batter will be thick.
- Spread the cake batter evenly into the prepared pan.
Topping
- In a bowl, combine the flour, sugar, brown sugar, cinnamon, nutmeg and salt. Drizzle with the melted butter and toss together with a fork until moistened and crumbly. Sprinkle over the cake batter.
- Bake the cake on the center oven rack for about 25-30 minutes, until a toothpick or cake tester inserted in the center comes out clean.
- Cool for 10-15 minutes, and serve warm.
Notes
- Leftover coffee cake should be stored in an airtight container for up to 5 days.
- Make this cake ahead by baking it the night before! Warm up pieces by microwaving for 15-20 seconds on 50% power for a just-baked texture.
