Banana Coffee Cake

Ingredients

• 2 cups all-purpose flour
• 1 cup light brown sugar (packed)
• 1/2 cup granulated sugar
• 1 1/2 teaspoons baking powder
• 13 tablespoons salted butter (chilled & cubed)
• 1 teaspoon ground cinnamon
• 2 large eggs
• 2 large overripe bananas ((mashed, about 1 cup))
• 2/3 cup powdered sugar
• 1 tablespoon milk
• 1/4 teaspoon vanilla extract

Instructions

1. 1

   Preheat the oven to 375℉ Line a 9x9-inch square pan with parchment paper or spray with nonstick cooking spray. Set aside.

2. 2

   In a large mixing bowl, whisk together the flour, light brown sugar, granulated sugar, and baking powder until combined.

3. 3

   Add in the chilled cubed butter and use a fork or pastry cutter, or your clean hands, to blend the butter into the mixture until it's a coarse crumbs mixture with chunks of butter throughout.

4. 4

   Measure out 1¼ cups of the crumb topping mixture and place it into a smaller separate bowl. Whisk the ground cinnamon into it. Cover the bowl with plastic wrap or a lid and set it in the freezer for now.

5. 5

   To the remaining crumb mixture in the large mixing bowl, add in the eggs and mashed bananas and mix together with a rubber spatula until combined.*It will look really dry at first, but as you gently mix it together it will form a thicker and creamy batter that is still slightly lumpy.

6. 6

   Spread half of the banana batter into the prepared baking dish and spread it out into an even layer.

7. 7

   Remove the crumb mixture from the freezer and evenly sprinkle 1/2 cup of it over the banana batter layer inside the baking pan. Place the remaining crumb mixture back into the freezer (you will use the rest of it later).

8. 8

   Carefully dollop spoonfuls of the remaining banana batter over top the cinnamon crumb layer. Use a plastic spoon or spatula to carefully spread it out evenly.

9. 9

   Bake for 13 minutes and then carefully sprinkle the remaining crumb mixture (from the freezer) over top, and continue cooking for an additional 15-20 minutes.*You may need to cover the cake loosely with a piece of foil to avoid it getting too browned. A toothpick inserted into the center of the cake should come out clean or with moist crumbs, and the top and sides of the coffee cake should be a golden brown.

10. 10

    Remove the banana coffee cake from the oven and allow it to cool, inside the pan at room temperature, for 1 hour before glazing it.

11. 11

    To Make The Glaze : Add all the glaze ingredients into a small bowl and whisk together until it's a pourable glaze consistency. Use a fork or spoon to drizzle the glaze over top the cooled cake.
