Espresso Banana and Butterscotch Layer Cake

This Espresso Banana-Scotch Layer Cake pairs the deep, bittersweet notes of espresso with a creamy banana-Scotch Swiss meringue buttercream for a unique and memorable dessert.

Layers of tender espresso cake are filled with banana-Scotch buttercream and finished with crisp dried banana chips for texture and visual appeal.

One of my favorite baking rules is simple and true: If ingredients grow together, they often taste great together. Bananas and coffee thrive in the same climates, and that natural connection inspired this cake. The result is surprising, sophisticated, and utterly delicious.

The espresso flavor in the cake complements the sweet, caramel-like banana-Scotch filling. Crisp dried banana chips on top add a crunchy contrast to the silky Swiss meringue buttercream. This cake works well for celebrations or whenever you want a dessert that balances bold coffee flavors with a soft, tropical sweetness.

About this recipe

• Bake this recipe in three 8″ pans or four 6″ pans, depending on how tall you want the final cake.
• The cake calls for espresso powder. If you don’t have espresso powder, dissolve 3 tablespoons of instant coffee in 1/4 cup of the milk and add it to the wet ingredients. Be sure the coffee is fully dissolved.
• You can use any buttercream you prefer (Swiss meringue, Italian, or a classic American buttercream), but Swiss meringue gives a silky, less sweet finish that pairs beautifully with banana-Scotch.
• Before filling and frosting, taste the buttercream and adjust the banana-Scotch amount if you want a stronger banana flavor.

Happy baking!

Ingredients

Espresso Cake

• 6 large egg whites, room temperature (240 g / 8.5 oz)
• 2/3 cup whole milk
• 3 tablespoons espresso powder (or 3 tbsp instant coffee dissolved in 1/4 cup milk)
• 2 teaspoons vanilla extract
• 3 cups cake flour (336 g / 12 oz)
• 1 1/2 cups sugar (300 g / 10.5 oz)
• 4 teaspoons baking powder
• 1 teaspoon salt
• 2 sticks unsalted butter, softened and cut into 12 pieces (226 g / 8 oz)

Banana-Scotch Swiss Meringue Buttercream

• 6 large egg whites (200 g / 7 oz)
• 1 1/4 cups sugar (250 g / 9 oz)
• 1/4 teaspoon cream of tartar
• 4 sticks unsalted butter, softened (450 g / 16 oz)
• 2 teaspoons vanilla extract
• 1/8 teaspoon sea salt
• 1/2 cup prepared Banana-Scotch (see linked recipe)
• 1 cup dried bananas for decoration (optional)

Coffee Syrup for Soaking

• 1 cup strong hot coffee
• 1 cup sugar

Instructions

Cake

1. Preheat the oven to 350°F (175°C). Line three 8″ pans or four 6″ pans with parchment and grease the sides.
2. Whisk together the milk, egg whites and vanilla extract; set aside.
3. In the bowl of a standing mixer, combine the cake flour, espresso powder, sugar, salt and baking powder using the paddle attachment on low just to mix.
4. Raise the mixer to medium and add the butter, one piece at a time, until the mixture becomes moist and crumbly.
5. Add half a cup of the liquid mixture to the bowl. Once incorporated, let the mixer run about 1 minute.
6. Add the remaining liquid and mix briefly, just until combined.
7. Divide the batter evenly between the prepared pans and bake on the middle rack for 18–20 minutes, or until a toothpick inserted in the center comes out clean.

Swiss Meringue Buttercream

1. Combine egg whites, cream of tartar and sugar in a mixing bowl. Place the bowl over a pan with simmering water (bain-marie), whisking constantly.
2. Heat and whisk until the mixture thickens and registers about 150°F (or feels too hot to touch).
3. Transfer the bowl to the stand mixer and whip on high with the whisk attachment until the meringue is glossy, cool and forms very stiff peaks.
4. With the mixer on high, add the softened butter in small pieces, then add vanilla extract and salt.
5. Continue mixing until the buttercream is smooth, airy and light. If it looks separated at first, keep mixing; it will come together.
6. Stir in the banana-Scotch until evenly incorporated. Taste and adjust the banana-Scotch amount to intensify the banana flavor if desired.

Soaking Syrup

1. Combine the strong hot coffee and sugar in a small saucepan and boil briefly until the sugar dissolves.
2. Remove from the heat and let cool slightly before using to soak the cake layers.

To Assemble

1. Place one cake layer on a serving plate. Brush with about 1/3 cup of the coffee syrup to lightly soak the layer.
2. Spread roughly 1/3 of the banana-Scotch buttercream over the soaked layer. Repeat with the second layer and remaining syrup and buttercream.
3. Use the remaining buttercream to frost the outside of the cake. Garnish with dried banana chips or fresh banana slices just before serving.

Tips and Serving Suggestions

Check the buttercream flavor before filling so you can adjust the banana intensity. If you prefer a stronger coffee presence, increase the espresso powder slightly or brush more coffee syrup into the cake layers. For a lighter finish, choose a Swiss meringue buttercream; for a richer, denser frosting, an Italian buttercream also works well.

To store, keep the cake covered in the refrigerator and bring slices to room temperature for the best texture and flavor before serving. This cake makes an elegant centerpiece and pairs beautifully with a strong cup of coffee or a simple espresso shot.
