Instructions

Banana Cake

Preheat oven to 350°F. Spray a 10 cup bundt pan with a baking non-stick spray. Spray well.
In a mixing bowl, sift the flour, baking powder, baking soda, salt, cinnamon, and nutmeg. Set aside. Mash the bananas on a plate using a potato masher or a fork.
Using a mixer, beat the butter and sugar on medium-high for 3 minutes. Add in vanilla, mashed bananas, and sour cream. Mix until combined. Scrape the bowl. Add in eggs one a time. Mix on low. Scrape the bowl.
Slowly add in dry ingredients. Scrape the bowl and mix on low for 10 seconds. Mix the cinnamon filling into a small bowl. Mix the brown sugar, flour and cinnamon well.
Pour half the batter into the pan. Top the batter with the cinnamon filling. Use all of it. Top with the rest of the batter.
Bake for 45-55 minutes. About half way through, top the cake with foil to avoid over baking on top. The cake is done baking when a toothpick inserted comes out clean.
Let the cake sit in the pan for 10 minutes before transferring to a cooling rack. Let the cake cool completely.

Crumb Topping

Preheat oven to 350°F. Spray a cookie sheet with non-stick spray. In a mixing bowl, mix the brown sugar, sugar, cinnamon, salt, and flour. Melt the butter in the microwave. Pour the butter into the dry ingredients. Use a fork to mix until large chunks remain.
Bake for 6 minutes. Let it cool completely. It will appear melty, but use a rubber spatula to stir the crumbles.

Glaze

Mix sifted powdered sugar, vanilla, and milk. Whisk until it is a pourable texture. Pour glaze on top of the cake. Top with crumble.

Notes

Flour- Spoon and level the flour or use a kitchen scale. Compacted flour can dry out the cake.

High altitude baking- Add an extra 2 tablespoon of flour.
