Ingredients

To make this Creamy Banana Crumble Cake, gather the following:

• 3 ½ cups all-purpose flour
• 2 teaspoons baking powder
• ½ teaspoon baking soda
• 1 teaspoon salt
• 1 ½ cups unsalted butter, softened
• 2 cups granulated sugar
• 4 large eggs
• 1 ½ cups mashed ripe bananas
• 2 teaspoons vanilla extract
• 1 ¼ cups buttermilk

For the Frosting

• 1 ½ cups unsalted butter, softened
• 5 cups powdered sugar
• 2 teaspoons vanilla extract
• 4 tablespoons heavy cream

For the Crumble Topping

• ¾ cup all-purpose flour
• ½ cup light brown sugar
• ½ cup granulated sugar
• 1 teaspoon cinnamon
• ½ cup unsalted butter, melted

Garnish

You can adapt the recipe for dietary needs: use a dairy-free milk plus lemon juice in place of buttermilk, or substitute a 1:1 gluten-free flour blend if needed. Keep in mind substitutions may change texture slightly.

Instructions

1. Preheat the oven to 350°F (175°C). Grease and line four 8-inch round cake pans with parchment paper.
2. Mix dry ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. Cream butter and sugar: In a large bowl, beat the softened butter and granulated sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the mashed bananas and vanilla.
4. Combine batter: Add the dry ingredients to the wet mixture in three additions, alternating with the buttermilk. Begin and end with the dry ingredients, mixing just until combined to avoid overworking the batter.
5. Bake: Divide the batter evenly among the four prepared pans. Bake 22–25 minutes, or until a toothpick inserted into the center comes out clean.
6. Cool: Let the layers cool in the pans for 10 minutes, then transfer to wire racks to cool completely before assembling.
7. Make the frosting: Beat softened butter until creamy. Gradually add powdered sugar, then vanilla and heavy cream, beating until light and fluffy.
8. Prepare the crumble: In a bowl, combine flour, brown sugar, granulated sugar, and cinnamon. Pour melted butter over the mixture and stir until crumbly.
9. Assemble: Place the first cake layer on a board or plate, spread a generous layer of frosting, and repeat with remaining layers. Frost the top and sides of the stacked cake.
10. Finish: Sprinkle the crumble generously over the top of the frosted cake and add banana slices for garnish.

Notes & Tips

• Use very ripe bananas: Bananas with brown spots are sweeter and more flavorful—ideal for this cake.
• Avoid overmixing: Stir the batter just until the ingredients are combined to keep the cake tender.
• Even layers: For consistent baking, weigh the batter and distribute equally among pans.
• Freeze ahead: Cake layers freeze well when wrapped tightly; thaw before frosting.
• Watch the crumble: If the crumble browns too quickly, cover loosely with foil while baking the cake layers or toast the crumble separately and apply after frosting.

Cooking Tips

• Use an electric mixer to whip the frosting for a light, smooth texture and to avoid lumps.
• For very even layers, use a kitchen scale to portion the batter for each pan.
• If frosting softens during assembly, chill the cake briefly between layers to firm up the frosting for neater stacking.

Serving Suggestions

Serve slices at room temperature with a hot cup of coffee or tea to balance sweetness. For a special treat, pair with a scoop of vanilla ice cream or a light drizzle of caramel sauce. The cake also pairs nicely with tropical flavors—think coconut-based sides or drinks—to highlight the banana notes.

Frequently Asked Questions (FAQs)

• Can I make this gluten-free? Yes—use a trusted 1:1 gluten-free flour blend. Texture may vary slightly.
• Don’t have buttermilk? Combine 1 tablespoon lemon juice or vinegar with 1 ¼ cups milk and let it sit for 5 minutes to curdle; use as a substitute.
