his banana bread coffee cake is absolutely incredible! if you want a coffee cake that has a strong banana bread flavor, this is for you! My favorite part about this cake is the texture. The actual cake is very soft and moist with a great banana flavor. Then, topping adds a great crunch. The texture is just perfect.
Recipe note- This used to be a bundt pan recipe but I updated the recipe, so it is easier to make.

Tips for making the cake

Here are my tips, so yours turns out like this recipe!

  • Tip 1: Make sure not to compact your flour when scooping. I recommend using a spoon to scoop the flour into your measuring cup as pressing it into the flour and scooping against the side of the container can compact the flour and dry out your cake.
  • Tip 2: Make the crumble topping and cinnamon filling first, before making the banana batter.
  • Tip 3: For assembling, spread half of the banana cake batter and the cinnamon filling on top. Add the rest of the banana cake batter. Add it in dollops evenly on top of the filling and use an offset icing spatula to spread to more easily. Then, add the crumble on top.
  • Tip 4: The vanilla icing adds extra sweetness to the cake. It also helps to soften the texture of the crumble.

Instructions

    1/2 cup Brown sugar, 1/4 cup White granulated sugar, 1 1/2 tsp Ground cinnamon, 1/4 tsp Salt, 1 cup All-purpose flour, 9 TBSP Unsalted butter

    1/2 cup Brown sugar, 1 1/2 tsp Ground cinnamon, 1/2 tsp Unsweetened cocoa powder

Banana Bread

  • Preheat the oven to 350°F. Spray a 9X9-inch square pan with baking nonstick spray. Line the bottom and sides with parchment paper and spray again.
  • In a large bowl, mix the melted butter (make sure it is cooled to room temperature), brown sugar, sugar, vanilla, eggs, sour cream, and mashed bananas (mash these well before adding to the bowl). Use a whisk to mix until combined and smooth.
    1/2 cup Unsalted butter, 1/2 cup Brown sugar, 1/4 cup White granulated sugar, 2 Large eggs, 1/4 cup Sour cream, 1 tsp Pure vanilla extract, 3 Medium over ripe bananas

    2 cups All-purpose flour, 1/4 tsp Baking soda, 1/2 tsp Salt, 1 tsp Baking powder
  • Pour half of the banana batter into the pan and smooth using a rubber spatula. Sprinkle the cinnamon filling evenly on top of the batter. Spread the rest of the banana batter on top of the filling.
  • Pull the cinnamon topping out of the fridge and use your hands to break up the big clumps before sprinkles on evenly on top of the batter.
  • Bake for 41-26 minutes until a toothpick inserted comes out clean.
  • Let the cake sit on the hot pan for 10 minutes. Transfer the cake to a cooling rack by holding on to the parchment paper on the sides to lift it out of the pan.

  • Mix in a small bowl, mix the powdered sugar, vanilla, and milk. Add a little bit of milk at a time and mix until it is pourable.
    1 cup Powdered sugar, 1 tsp Pure vanilla extract, 2 TBSP Milk
  • Pour the glaze on top of the cooled cake.

Notes
