Got ripe bananas? Try something other than banana bread: a super moist, tender banana coffee cake with a sweet cinnamon streusel filling. Easy to make from scratch and even better than the bakery—perfect for breakfast or an afternoon treat with hot coffee.
I always buy a bunch of bananas each week, and inevitably a few start to brown. Instead of worrying about them, I see opportunities for delicious banana recipes—muffins, pies, smoothies, donut holes, pancakes, or the classic banana bread. This week I wanted a change from the usual loaf and went for a coffee cake that’s soft, crumbly, and filled with cinnamon streusel.
Who doesn’t love a sweet, crumbly coffee cake with a hidden layer of cinnamon streusel between pillowy-soft banana layers? It’s cozy, comforting, and perfect for slow mornings shared with family or friends.
Let’s gather the ingredients and bake one together.
There are so many warm memories tied to coffee cake: sitting around a table with a hot cup of coffee, enjoying conversation while the cake fills the house with a sweet cinnamon aroma. That slow, relaxed morning feeling with a good meal is hard to beat.
Ready to make your own Banana Coffee Cake?
• Preheat oven to 350°F (175°C). Lightly grease an 8×8 inch pan.
• In a large bowl, whisk together flour, granulated sugar, brown sugar, baking powder, baking soda, and salt. Set aside.
• In a medium bowl, mash the bananas. Add sour cream, oil, egg, and vanilla; mix until combined. Stir the wet mixture into the dry ingredients until just combined.
• For the streusel: in a small bowl, combine flour, brown sugar, cinnamon, and melted butter until crumbly. Spread half the batter evenly into the prepared pan, sprinkle with half the streusel, pour the remaining batter over the streusel, and top with the remaining streusel.
• Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean.
• For the glaze: whisk powdered sugar, heavy cream, and vanilla until smooth. Drizzle over the warm cake, slice, and serve.
