This homestyle cake is a family recipe made of two soft banana layers loaded with black walnuts. Old fashioned caramel frosting makes it a true southern favorite.
Here it is, my favorite homestyle cake – my mother’s recipe. The last time I had a large family dinner (remember those?) I made a different black walnut cake from a fancy cookbook, and from the author’s confidence and praise of her own cake, I felt so sure it would be just as good as this one. It was not.
I often spring new recipes on my family, and some are better than others, but this time I was embarrassed. The cake looked beautiful on the outside but it was a huge disappointment flavor-wise and dry. Sooo dry. I already had the best black walnut cake recipe from my mom, and I should have just made it instead.
Black walnuts are harvested as a fall crop, but as a southerner I can tell you they are never out of season in our kitchens. They have bold, earthy flavor and one whiff of their robust fragrance brings to mind all the special confections my family makes with them. (Aunt Pammy’s peanut butter fudge and Aunt Grace’s Easter fondants, to name two.)
Thankfully, black walnuts are available for purchase online year-round, so they can remain on our tables in spring and summer months. I’ve had Easter on the brain lately, and I think this cake would be so delicious and special as the last course, but it is also so appropriate for a Thanksgiving dessert.
The caramel frosting is easy enough to whip together, but it is prone to set up quickly. I found myself intermittently whipping more heavy cream into it so it could be spreadable on the cake. The good news is, you don’t have to worry about getting the frosting perfectly even because it will be completely covered with more black walnuts.
There is one addition to this recipe from me, and that is a few swirls of cream cheese frosting on the top edge of the cake. This makes it look pretty, and it’s really delicious, too!
I suppose the “Tennessee” part of this recipe could refer to the black walnuts, or maybe the old fashioned caramel frosting – which is truly something that all southern, church-going, potluck-attending grannies have made to cover a special cake. I can only tell you for sure that as a born-and-raised Tennessean, this cake is the real deal.
The interior of this cake is so soft and tender that I’m pressed to find the right words to describe it. I’d almost call it damp, which may be a questionable description for food, but it is indeed super-moist and so flavorful with the addition of four overripe bananas.
(Thanks for the recipe, mom!)
Mom’s Tennessee Banana Black Walnut Cake
- 8-inch cake pans
- 2 cups all purpose flour
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 2 teaspoons cinnamon
- 3/4 cup unsalted butter softened
- 1 1/2 cups granulated sugar
- 2 eggs well beaten
- 4 whole bananas overripe
- 1/2 cup buttermilk
- 1 teaspoon vanilla extract
- 1 cup black walnuts chopped
- 1/2 cup unsalted butter
- 1 cup light brown sugar
- 1/3 cup heavy cream plus more if needed
- 1 tablespoon vanilla extract
- 4 cups confectioners' sugar
- 1 1/2 cups black walnuts finely chopped
Cream Cheese Frosting
- 1/2 cup unsalted butter softened
- 1 oz. cream cheese softened
- 2 to 2 1/2 cups confectioners' sugar
- 3-4 tablespoons milk or cream to thin
- 1 tablespoon black walnuts finely chopped
For the cake layers
- Preheat oven to 350°F. Spray two 8- or 9-inch cake pans withflour-based cooking spray (or grease and flour) and set aside.
- In a medium bowl, sift together flour, baking soda, salt and cinnamon in a separate bowl. In the bowl of an electric mixer, cream the butter and sugar thoroughly. Blend in bananas, eggs and vanilla. Add the flour mixture alternately with buttermilk until well incorporated, then fold in walnuts. Divide the batter evenly between the prepared pans and bake for 35 minutes for8-inch pans, or 30 minutes for 9-inch pans, or until a toothpick inserted into the center of a cake comes out clean. Cool in pans on a cooling rack for 10minutes, then turn out of pans to cool completely.
For the caramel frosting
- Melt the butter in a saucepan over medium heat on thestovetop. Add brown sugar and heavy cream, stirring until sugar is dissolved,about 5 minutes. Remove from heat and add vanilla extract. Transfer the mixtureto the bowl of an electric mixer while still warm and melted. Beat onmedium-low speed while adding powdered sugar a little a time; mix until smoothand thick. Add additional heavy cream a tablespoon at a time until the frostingis of easy spreading consistency. This frosting firms quickly, almost to afudge-like state, so work quickly to frost the cake.
- Place a small amount of frosting on the center of a cakeplate to keep the cake from shifting. Place one layer on the cake plate, andapply a layer of frosting. Top with the other cake layer, and frost the outsideand top of the stacked layers. If the frosting begins to set up, add more heavycream and re-whip to soften. Immediately press chopped black walnuts onto thetop and sides of the cake, before frosting sets up.
For the cream cheese frosting
- Combine the butter and cream cheese in a large bowl and whip until fluffy with an electric hand mixer. Add confectioners’ sugar a little ata time until a thick, fluffy frosting forms; add milk or cream to thin as needed. Transfer the frosting to a piping bag with a large closed star piping tip. Pipe swirls of cream cheese frosting on the top edge of the cake. Garnish with black walnuts.
Hi, I tried to make it, I was so impressed with the description, when I started to read the directions the eggs and the sugar were not among the ingredients! I really you would revise it and add them so we can enjoy it too!
Thank you so much for letting me know. When we changed to a new printable recipe format some things were left off or got jumbled around. I’m so sorry. It’s fixed now. Please let me know if you need anything further.
