Banana Cinnamon Crumb Cake

Banana Cinnamon Crumb Cake

This crumb cake is super moist and comes together pretty quickly! I whipped it up yesterday before heading home to see my family.

It’s an ideal option for breakfast or a snack in the afternoon. Takes around 40-45 minutes to bake, and it’s best when it’s enjoyed warm. Here’s the full recipe🩵


  • 4 ripe bananas, mashed
  • 2 cups flour
  • 3 teaspoons baking powder
  • 1 1/2 teaspoons ground cinnamon
  • 1/2 teaspoon salt
  • 1 stick unsalted butter
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 1/2 teaspoons vanilla @singingdogvanilla
  • 1 cup milk (whole milk works great)


  • 2/3 cup flour
  • 2/3 cup brown sugar
  • 1/3 cup sugar
  • 1 1/2 teaspoons cinnamon
  • 6 tablespoons unsalted butter, softened


  • 1/2 cup powdered sugar
  • 2-3 tablespoons milk


  1. Preheat the oven to 350° F. Grease the sides of a 9×9 baking dish. Place parchment paper on the bottom and grease it as well.
  2. Mash the 4 bananas in a medium bowl and set aside.
  3. Combine the dry ingredients in one bowl and set them aside.
  4. Use a stand mixer or a hand-held mixer to beat the butter for a couple of minutes until it’s fluffy. Add sugar and continue to beat until combined. Then, add the eggs and vanilla extract. Mix in the mashed bananas.
  5. Gradually add the dry ingredients and milk alternately, a little at a time, until it’s fully combined.
  6. Make the crumb by combining all the ingredients and fork in the softened butter. Pour half the batter into the dish and add a layer of crumb. Then, add the rest of the batter and smooth it out with a spatula. Sprinkle the remaining crumb on top.
  7. Bake for 40-45 minutes until it’s golden brown and a toothpick comes out clean. Let it cool for 10-15 minutes.
  8. Mix the icing ingredients in a small bowl. Drizzle it over the cake, slice, and enjoy!
