Why You’ll Love This Coffee Cake

Uses Up ALL Those Leftover Bananas. Brown, mushy, over-ripe bananas are great for baking, and for a delicious twist on a classic loaf of moist banana bread, this banana bread coffee cake has all the flavor you love, but with a buttery crumb topping.

Easy to Make. This is one of those recipes that’s perfectly uncomplicated, requiring nothing more than just whisking together wet and dry ingredients. It bakes up in about a half hour, and is ready to eat right away!

Delicious Warm or Cold. You can enjoy this coffee cake warm from the oven, or at room temperature. It’s even great days later!

See the recipe card at the end of the post for the full ingredients list and instructions.

Ingredients

Cake

For the liquid ingredients, you’ll need melted butter, dark brown sugar, eggs, vanilla extract and very ripe mashed bananas. Then for the dry ingredients, all-purpose flour, baking powder, baking soda, coarse Kosher salt, cinnamon and nutmeg.

Topping

A good crumble topping starts with all-purpose flour and sugar (I use both white and brown), cinnamon and nutmeg for spice, coarse Kosher salt to balance the sweetness, and melted butter to bind it all together.

Instructions

Cake

  • Preheat the oven to 350 F, and spray a 9×9 inch baking pan with non-stick spray.
  • In a large mixing bowl, whisk together the melted butter, brown sugar, eggs, vanilla and mashed bananas.
  • Separately, sift together the flour, baking powder, baking soda, salt, cinnamon and nutmeg. Add the dry ingredients to the wet, and stir together with a spatula, just until moistened. The batter will be thick.
  • Spread the cake batter evenly into the prepared pan.

Topping

  • In a bowl, combine the flour, sugar, brown sugar, cinnamon, nutmeg and salt. Drizzle with the melted butter and toss together with a fork until moistened and crumbly. Sprinkle over the cake batter.
  • Bake the cake on the center oven rack for about 30 minutes, until a toothpick or cake tester inserted in the center comes out clean.
  • Cool for 10-15 minutes, and serve warm.

Frequently Asked Questions

How long does the cake stay fresh?

Store leftover coffee cake in an airtight container, and it will still taste great for up to 4-5 days.

Will this recipe work with bananas that have been frozen and thawed?

Very ripe bananas that are soft and have a few brown spots have the best, sweetest flavor for baking. When I have too many bananas that are getting too ripe, I will often peel them, and wrap them individually in plastic wrap to use later in smoothies. You can let them thaw, mash them, and use them for baking, and they work great.

Can I make the coffee cake in advance?

You can absolutely bake this the night before to serve in the morning, and it will be fantastic. Warm up individual pieces by microwaving them for 15-20 seconds on 50% power for a just-baked texture.

Can this recipe be doubled?

Yes, you can double the recipe and bake it in a 9×13 pan. Check the center for doneness after 30 minutes of baking.
