How to Make the Recipe

Step 1

Preheat your oven to 350°F and prepare your cake pans by greasing and flouring them or lining with parchment paper.

Step 2

In a large bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

Step 3

In a separate mixing bowl, cream the softened butter with granulated and brown sugar until light and fluffy.

Step 4

Beat in the eggs one at a time, followed by the vanilla extract.

Step 5

Add mashed bananas and mix until fully incorporated.

Step 6

Alternate adding the dry ingredients and buttermilk into the banana mixture, beginning and ending with the dry ingredients. Mix just until combined.

Step 7

Fold in the chopped pecans.

Step 8

Divide the batter evenly into your prepared pans and bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.

Step 9

Cool the cakes in the pans for 10 minutes, then transfer to wire racks to cool completely.

Step 10

While the cakes are cooling, make the caramel frosting by melting butter in a saucepan, then stirring in brown sugar and cream. Bring to a gentle boil, then remove from heat and let cool slightly.

Step 11

Beat the caramel mixture with sifted powdered sugar and vanilla until smooth and spreadable.

Step 12

Frost the cooled cake and garnish with chopped pecans.

Tips for Making the Recipe

Use overripe bananas for the sweetest and most flavorful results.
Don’t overmix the batter to avoid a dense texture.
Toast the pecans for extra depth of flavor.
Allow the caramel frosting to cool slightly before beating in powdered sugar to avoid melting.
Level your cake layers before frosting for a professional finish.

How to Serve

Serve this cake at room temperature to enjoy its full flavor and texture. It pairs beautifully with a cup of coffee, espresso, or even a scoop of vanilla bean ice cream. For special occasions, decorate with whole pecans or a drizzle of caramel sauce over each slice.

Make Ahead and Storage

Storing Leftovers

Wrap the cake in plastic wrap or store in an airtight container. It will keep well at room temperature for up to 2 days or in the refrigerator for 5 days.

Freezing

Wrap unfrosted cake layers tightly in plastic wrap and foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before frosting and serving.

Reheating

Let refrigerated slices come to room temperature for best texture. The cake does not require reheating, but a quick microwave burst (10–15 seconds) can enhance the caramel flavor slightly.

FAQs

1. Can I make this cake without nuts?

Yes, simply omit the pecans for a nut-free version without altering the rest of the recipe.

2. How ripe should the bananas be?

Very ripe bananas with lots of brown spots are ideal—they’re sweeter and mash more easily.

3. Can I use store-bought caramel for the frosting?

You can, but the homemade caramel frosting adds a unique depth and richness that store-bought can’t match.

4. Is buttermilk necessary?

Yes, it helps create a moist texture and reacts with baking soda for leavening. If needed, you can use a buttermilk substitute.

5. Can this be made into cupcakes?

Absolutely—adjust baking time to around 18–22 minutes and test with a toothpick.

6. How do I keep the frosting from becoming grainy?

Ensure the brown sugar fully dissolves in the butter and cream mixture before beating in powdered sugar.

7. What size cake pans should I use?

Two 9-inch round pans work well. You can also bake in a 9×13-inch pan for a single-layer version.

8. Can I add spices like cinnamon?

Yes, 1–2 teaspoons of ground cinnamon or a pinch of nutmeg adds great warmth to the cake.

9. How do I prevent the layers from sticking?

Grease and flour your pans thoroughly or use parchment paper rounds to ensure easy release.

10. Is this cake overly sweet?

Despite the frosting and banana, the sweetness is well-balanced, especially with the nuttiness from the pecans.
