Caramel Coffee Banana Cake

I’m repurposing last week’s banana cake recipe. The previous cake was baked in three tall 6-inch round cake pans. This adjusted recipe makes two 8-inch cake round layers.

The only different between last week’s banana cake recipe and this coffee banana cake is the addition of dark chocolate chunks!

The chocolate really adds another dimension. It takes it from a simple banana cake to a decadent dessert.

Assemble and Decorate Layer Cake

Caramel Coffee Banana Cake
  1. Soak bottom cake layer with a coffee liqueur mixture. Spread a generous layer of salted caramel on top.
  2. Fill cake. There are numerous ways to do this. The easiest and cleanest way to fill a cake is with a piping bag. Simply pipe a spiral of buttercream over the cake layer. Using this method, you can achieve a nice even layer of buttercream without use of a cake turntable or an offset spatula.
  3. Stack top cake layer and coat assemble cake with a thin layer of buttercream to seal in any cake crumbs (known as the crumb coat). Place in the fridge to harden for 15 minutes. Once chilled, coat cake with a second thicker layer of buttercream. Then, return to refrigerator until you ready to decorate and serve.
  4. Decorate the cake! Drizzle the assembled banana cake with caramel sauce. Gather an assortment of chocolate goodies. Some options photographed in the image above include: chocolate covered espresso beans, chocolate covered coffee beans, cacao nibs, and chopped dark chocolate. To highlight the banana cake, garnish the cake with freeze dried banana slices or banana chips.

Cake Decor Options

Decorate the caramel banana cake as minimal or as over the top as you’d like! Choose to keep it simple like the image on the left, or add all the toppings like image on the right.

Or, skip the caramel drizzle and chocolate garnishes. Decorate using a piping bag as shown in this classic chocolate cake or apple cider layer cake.

And, if you prefer less frosting, try the naked cake look like this coconut cake.

Make Ahead Option

Pressed for time? This layered caramel banana cake can be made over the course of several days. The banana cake can be baked several weeks in advance!

  • Banana Cake: Make and bake banana cake as directed in recipe card. Cool cakes to room temperature. Individually wrap each cake layer tightly with plastic wrap. For extra protection, place wrapped cake in a freezer zip-top bag. Defrost in the fridge overnight, or defrost at room temperature for a few hours.
  • Coffee Buttercream: Swiss buttercream freezes well! Make the buttercream according to recipe instructions. Chill in the fridge until cold (about 2 hours). Then, transfer to an airtight container and keep in the freezer for up to two weeks. Defrost overnight in the fridge, or defrost at room temperature for several hours. Once softened, give the buttercream a good beating or whisking until smooth and fluffy.

Slicing and Serving Cake

Layer cakes are much easier to slice when cold. This will also result in clean slices.

Slice the caramel banana cake while it is cold. Then, allow cake slices to sit at room temperature for about 20 minutes to soften. Longer is even better!

This two layered 8-inch round cake serves 14 when slices into standard cake wedges.

Cake Storage and Leftovers

Fully assembled, frosted cake may be stored in the fridge for up to 48 hours before serving.

Once sliced, store partial cake or cake slices in an airtight container for up to three days. It is important to use an airtight container because the cake and buttercream will absorb the aroma and flavors inside your fridge.

Coffee Swiss Buttercream:

Once all the butter is incorporated, add coffee concentrate mixture. Increase speed to medium-high and continue to beat until buttercream is light and fluffy
