Step 1

Preheat oven to 350 degrees F. Spray a 9x13 or 8x11 glass pan with nonstick spray.

Step 2

In a large bowl, combine the eggs, sugar, melted butter, buttermilk and vanilla. Stir until combined. Add in bananas.

Step 3

Combine dry ingredients in a separate bowl. Mix 1/3 of the dry ingredients into the wet ingredients, stirring just until combined. Repeat until ingredients are completely mixed. (Note: quick breads/ cakes like this do better if mixed by hand! Don't over mix and it's okay if there are a few lumps!)

Step 4

Pour batter in the prepared pan.

Step 5

To prepare the crumb topping, combine all ingredients except butter. Cut butter into small pieces and add to the mixture. Using a pastry cutter (or 2 forks) blend the ingredients until crumbly. Pour over top of batter in the pan.

Step 6

Bake for 35-40 minutes. Let cool and drizzle with glaze.

Step 7

Whisk together the glaze ingredients until smooth and drizzle over cake as desired.
