Prep Time 15 minutes
Cook Time 35 minutes
Servings 20 servings
For the cake
- 3 cups cake flour not all-purpose, sifted and measured correctly
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/4 teaspoon ground cinnamon
- 3/4 cup butter at room temperature
- 1 cup granulated sugar
- 1 cup brown sugar packed
- 3 large eggs at room temperature
- 2 teaspoons pure vanilla extract
- 1 cup sour cream or Greek yogurt
- 1/2 cup whole milk
- 1 and ½ cups banana mashed, very ripe (about 3 bananas)
- 1 cup toffee chopped (Heath toffee bits or chopped Heath bars)
For the frosting
- 1 cup butter
- 8 cups powdered sugar sifted
- 1 teaspoon real vanilla extract
- 4 tablespoons heavy cream or whole milk
For the cake
Preheat the oven to 350 degrees.
Grease and flour three 8-inch cake pans.
In the bowl of your mixer, beat the butter until smooth. Add in the granulated and brown sugar and beat on low until combined, then on medium until smooth. This should take about 1 to 1 ½ minutes.
Add in the eggs, one at a time and mixing until just combined after each addition.
In a separate bowl, mix together the flour, baking powder, baking soda, salt, and cinnamon. Stir to combine.
In another bowl, mix together the sour cream, whole milk, mashed bananas, and vanilla extract. Whisk well.
Add your dry ingredients and your liquid ingredients alternately to the egg and sugar mixture. Beginning and ending with the flour mixture. Mix until just combined. Don't over mix.
Fold in a cup of chopped toffee. Reserve 2-3 tablespoons for the top of cake if desired.
Spoon evenly into prepared pans.
Bake at 350°F for approximately 30-35 minutes. Start checking at 25 minutes.
Remove from oven and set on racks to cool for 10 minutes. Turn out the cakes onto racks after 10 minutes to cool completely. Ice with browned butter toffee buttercream.
For the frosting
Melt butter in a saucepan on medium to low heat Whisk constantly. When it turns light brown remove the pan from the heat. Cool.
Add powdered sugar to the bowl of an electric mixer. Add heavy cream, vanilla, and browned butter to the powdered sugar.
Beat until smooth. Add more cream if frosting is too thick (or more powdered sugar if it's too thin.)
Wait until the cake is completely cool before frosting. For a more professional cake, remove the domes from the tops of the cake layers with a cake leveler or large serrated knife. Place one layer of cake on a serving plate. Spread about 1 cup of the frosting on top in an even layer. Repeat with the next layer of cake and frosting, then top the cake with the final layer of cake (if you have 3 layers). Frost the outside of the cake. An offset spatula makes it really easy to get an even layer.
Store in an airtight container on the countertop for 3 to 4 days. Or, in an airtight container in the refrigerator for 6 to 7 days.
