- 1 cup granulated sugar
- 1/2 cup brown sugar
- 2 eggs + 2 egg whites, room temp
- 2 tsp vanilla extract
- 1 1/4 cup whole fat buttermilk, room temp
- 2 1/2 cups cake flour
- 2 1/2 tsp baking powder
- 1/2 tsp baking soda
- 1 tsp kosher salt
For the salted caramel buttercream:
- 2 cups unsalted butter, chilled
- 4 cups powdered sugar, sifted
- 1 cup salted caramel (see recipe below)
- 1 tsp kosher salt
- 2 tbsp heavy cream
For the salted vanilla bean caramel:
- 2 cups granulated sugar
- 1/2 cups water
- 2 tsp corn syrup
- 1 tsp vanilla bean paste
- 1 tsp kosher salt
- 1 cup heavy cream
- 1/2 cup unsalted butter, cubed
Instructions
- Make your salted vanilla bean caramel. Add sugar, corn syrup, and water to a medium saucepan and heat on medium, whisking until the mixture begins to boil. Stop whisking immediately when this happens and wait, watching the bubbling sugar mixture, until it turns amber. Slowly add heavy cream and vanilla bean paste, whisking until smooth. Turn off the heat and add butter, whisking until melted. Add salt and whisk until combined. Transfer your caramel to a heatproof container and allow to cool to room temperature, covered. Store in fridge if needed. Allow to come to room temperature before using.
- Brown your butter by melting in a saucepan over medium heat, and allowing the butter to cook until it foams and begins to form brown speckles. At this point, immediately remove from heat and pour into a heatproof container. Allow to cool on the counter or in the fridge until it re-solidifies.
- Preheat your oven to 325 degrees F. Prepare 2 8-inch round cake pans with parchment and/or butter and flour.
- Make your cake batter. Cream solidified, room temp browned butter with the granulated sugar and brown sugar in the bowl of a stand mixer fitted with the paddle attachment. Add eggs one at a time, add vanilla, and mix on medium-high for 5 minutes until lightened in color and fluffy. In a separate medium bowl, whisk together dry ingredients (cake flour, baking soda, baking powder, salt). Reduce the mixer speed to low and alternate adding dry ingredient mix and streaming in buttermilk slowly, starting and ending with the dry mix (dry, buttermilk, dry, buttermilk, dry). Stop mixing as soon as the last flour streaks disappear. Divide batter evenly into your two cake pans.
- Bake cake layers for 35-40 minutes at 325 degrees, until the top is browned and a toothpick inserted comes out clean. Allow cakes cool on a wire rack and to come to room temperature completely before using.
- Make your salted caramel buttercream. In a mixing bowl fitted with the paddle attachment, cream cold butter for about 5 minutes until fluffy. Reducing mixer speed to low, add sifted powdered sugar 1/2 cup at a time until completely incorporated. Increase mixer speed to medium and add salted caramel and salt. Increase mixer speed to medium-high and whip buttercream until completely smooth, fluffy, and lightened in color, 3-5 minutes. Use immediately or store in fridge until later.
- Assemble your cake. Place the first cake layer on a cake round and pipe a thick circle of buttercream around the edge of the cake. Fill the piped edge with salted caramel. Place the second cake layer on top. Using your salted caramel buttercream, spread a thin layer of frosting all around the cake and smooth it out with a bench scraper and spatula. Place entire cake in the freezer for 30 minutes. Remove cake from freezer and frost with another layer of buttercream. Decorate with piping and salted caramel swoops and drips as desired. Serve at room temperature.
- Cake can sit at room temperature for several hours, then should be stored in the fridge in a cake box or covered container. Allow to come to room temp before serving.
