# Step-by-Step Directions:
01 -
Preheat oven to 175 °C. Grease and flour two 23 cm round cake pans or line them with parchment paper for easy release.
02 -
Toast chopped walnuts in a dry skillet over medium heat for 3-4 minutes until fragrant, stirring constantly. Allow to cool.
03 -
In a medium bowl, whisk together flour, baking powder, baking soda, and salt to ensure even distribution of leavening agents.
04 -
In a large bowl or stand mixer, beat softened butter and granulated sugar until pale and fluffy, about 3-4 minutes. Add eggs one at a time, then mix in vanilla extract.
05 -
Stir mashed bananas and buttermilk into the butter mixture until just combined, preserving moisture and flavor.
06 -
Alternately fold dry mixture and any remaining wet ingredients into batter, beginning and ending with dry ingredients. Gently fold in toasted walnuts without over-mixing to maintain a light crumb.
07 -
Divide batter evenly between prepared pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean with a few moist crumbs. Cool in pans for 10 minutes, then invert onto a rack to cool completely.
08 -
Toss sliced bananas with lemon juice and optional brown sugar; set aside. Chill mixing bowl and beaters for 10 minutes, then whip heavy cream, powdered sugar, and vanilla until stiff peaks form.
09 -
Place one cake layer on stand or plate. Spread a generous layer of whipped cream, then evenly add banana slices. Place second cake layer on top and cover entire cake with remaining whipped cream.
10 -
Decorate with additional walnuts, banana slices, chocolate shavings, or caramel drizzle as desired. Chill assembled cake for at least 1 hour to set layers before slicing and serving.
# Helpful Notes:
01 -
Use overripe bananas to maximize natural sweetness and moisture. Allow cake layers to cool completely before frosting to prevent melting and preserve presentation.
02 -
Chilling the assembled cake helps layers to set and provides clean slices.
03 -
For a dairy-free version, replace butter with dairy-free alternatives, buttermilk with plant-based milk plus lemon juice, and heavy cream with chilled coconut cream.
