banana coffee cake
- 1 1/4 c all purpose flour (150g)
- 1 c cake flour (120g) sub with all purpose
- 1 tsp baking soda
- 1/2 tsp baking powder
- 1/4 tsp salt
- 1 1/4 c mashed banana ~3 medium bananas
- 1/2 c brown sugar (110g)
- 1/2 c sugar (110g)
- 1/2 c unsalted butter, melted
- 2 large eggs, room temperature
- 1/2 c whole milk greek yogurt, room temperature
- 1 1/2 tsp vanilla
- 1/3 c brown sugar (67g)
- 1 tbsp ground cinnamon
- 1 tsp cocao powder, optional for color
- 1/2 c brown sugar (110g)
- 1/2 c flour (60g)
- 2 tsp ground cinnamon
- 4 tbsp unsalted butter, evenly cubed into small pieces
- 1 c powdered sugar
- 1-2 tbsp water or milk
- 1 tsp vanilla extract
Preheat oven to 350 F, line bottom of a springform pan with parchment paper. Lightly grease pan with butter. I use a pastry brush dipped in some of the melted butter. To make the streusel, combine dry ingredients together. Using a pastry cutter, work the butter into the dry mixture until its the consistency of finer sand. Once the mixture resembles wet sand, you can use your hands to work some of the pieces into slighly larger chunks of "wet sand." Place streusel topping into the fridge to chill until the cake is ready to be topped. To make the filling, whisk together the brown sugar, cinnamon and cocoa powder until very well combined.
In a stand mixer with whisk attachment (or by hand), beat butter and sugar until smooth and well combined. Add eggs, beating well after each one until well combined. Add mashed bananas and vanilla extract, beating until well combined.
In this order (dry ingredients, yogurt, dry, yogurt, dry), add dry ingredients to the wet alternating with the yogurt. Slowly beat each time until JUST combined. A few flour streaks is okay!
Pour 1/2 of the banana cake batter into the prepared pan. Scatter most (3/4) of the cinnamon filling over the batter. Using a knife, create swirls. Pour remaining batter on top. Scatter any remaining cinnamon over the top and repeat swirls. Top with the streusel.
Bake at 350F for 45 minutes. Check the topping. If its browning too quickly, top with a foil tent. Return to the oven for 10-15 minutes, checking for doneness every 5 minutes (55-65 minutes total). The top will be a deep golden brown and edges will pull slightly from the sides of the pan. When a toothpick inserted into the center comes out clean or with very few moist crumbs, its done. Cool in pan for 20 minutes. Gently remove from the spring form pan. Cool an addtional 30-45 minutes to room temperature. If topping with glaze, combine all glaze ingredients in a bowl until smooth and well combined. Pour over the cooled coffee cake. Allow 30 minutes for the glaze to set. Slice and enjoy with a cup of coffee!
