Banana Bread Crumb Cake

I was planning to make banana bread but then told my husband about this cake. He did not hesitate before casting his vote. 😉 It was incredibly moist and delicious- and easy to make. I loved the crumb layer inside the cake.

This recipe was adapted from cookiesandcups.com. I weighed the ingredients, used unsalted butter, incorporated whole wheat pastry flour and cinnamon, omitted the glaze, and modified the baking time for a convection oven. We ate it for breakfast and dessert!

Yield: one 9×13-inch cake

For the Cake:

• 120 g (1 cup) all-purpose flour
• 120 g (1 cup) whole wheat pastry flour
• 3 tsp baking powder
• 1 tsp Morton kosher salt
• 1/2 tsp ground cinnamon
• 3 ripe medium-sized bananas, mashed
• 8 T (1 stick, 1/2 cup) unsalted butter, room temperature
• 400 g (2 cups) granulated sugar
• 2 large eggs
• 1 tsp pure vanilla extract
• 1 cup milk (I used 2%)

For the Crumb Filling & Crumb Topping:

• 16 T (2 sticks, 1 cup) cold unsalted butter, cubed
• 432 g (2 cups) light brown sugar
• 120 g (1 cup) all-purpose flour
• 120 g (1 cup) whole wheat pastry flour
• pinch coarse salt

1. Preheat oven to 350°F. (I set my oven to true convection.)
2. Coat a 9×13 metal baking dish with baking spray, line with parchment paper (overhang on long sides), lightly coat with baking spray; set aside.
3. Make the Cake Batter: In a medium bowl whisk together flour, baking powder, salt, and cinnamon. Set aside.
4. In a large bowl stir together the mashed bananas, butter, sugar, eggs and vanilla until mixed well.
5. Add in the flour mixture and milk in alternating portions and stir until combined. Set batter aside while you make your crumb mixture.
6. Make the Crumb Filling & Crumb Topping: In a large bowl combine the cold, cubed butter, light brown sugar, and flours using a pastry blender or fork until a coarse crumb forms.
7. To Assemble: Pour 1/2 of the batter into the prepared pan. Top with 1/3 of the crumb mixture. Cover the filling with the remaining batter and then top with remaining crumb mixture.
8. Bake for 40 minutes on convection or up to 50-55 minutes in a conventional oven, or until the center is set and a toothpick comes out clean.
9. Serve warm or at room temperature. Store leftovers tightly wrapped at room temperature.
