Ingredients
  

Banana Cake

  • 1.5 cups all-purpose flour
  • 0.75 teaspoon baking soda
  • 0.5 teaspoon salt
  • 6 tablespoon unsalted butter, melted
  • 0.5 cups granulated sugar
  • 0.5 cups light brown sugar, packed
  • 0.33 cups sour cream, room temp
  • 1 large egg, room temp
  • 2 teaspoons vanilla extract
  • 0.75 cups mashed ripe bananas (about 2 medium bananas)

Cinnamon Sugar

  • 3 tablespoon light brown sugar
  • 1.5 teaspoons cinnamon

Crumble

  • 1 cup + 2 tbsp all-purpose flour
  • 1 teaspoon cinnamon
  • 0.33 cups granulated sugar
  • 0.33 cups light brown sugar, packed
  • 0.5 cups unsalted butter, melted

Icing

  • 0.5 cups powdered sugar
  • 1 tablespoon milk

Instructions
 

Preparation

  • Preheat your oven to 325F and grease and line an 8×8 baking pan, allowing the paper to hang over the sides for easy removal.
  • Start by making the crumble – Combine the flour, cinnamon, and sugars in a bowl. Then mix in the melted butter. The mixture should resemble wet sand. Place the bowl in the refrigerator to chill while the rest of the cake is made.
  • For the banana cake, whisk together the flour, baking soda, and salt in a medium bowl. Set aside.
  • In a large mixing bowl, whisk together the sugars and butter.
  • Once fully combined, whisk in the sour cream, egg, vanilla, and mashed banana.
  • Gently mix in the dry ingredients using a rubber spatula.
  • Spread half of the batter into the pan. Combine the cinnamon sugar mixture and sprinkle an even layer on top.
  • Cover with the remaining batter and gently spread it even.
  • Remove the crumble from the refrigerator. It should now be cold and firm. Crumble it on top in an even layer.
  • Bake for 40-45 minutes or until a toothpick in the center comes out clean with a few moist crumbs.
  • Allow the cake to cool for about 30-40 minutes.
  • While it cools, whisk together the powdered sugar and milk to make the icing. It should make a glue-like consistency. If it’s too thick, add ½ tablespoon of milk at a time until it turns smooth.
  • Drizzle the icing on top of the slightly warm cake and enjoy!

Notes

For a special touch, top with homemade salted caramel.
