Ingredients:
- 2 1/2 cups (300g) all-purpose flour, plus more for dusting pans
- 1 teaspoon (5g) baking powder
- 1/2 teaspoon (2.5g) baking soda
- 1/2 teaspoon (2.5g) salt
- 1 cup (227g) unsalted butter, softened
- 1 3/4 cups (350g) granulated sugar
- 2 large eggs
- 1 teaspoon (5ml) vanilla extract
- 1 cup (240ml) buttermilk, room temperature
- 1 cup (227g) unsalted butter
- 2 cups (400g) granulated sugar
- 1 cup (240ml) heavy cream
- 1/2 teaspoon (2.5ml) vanilla extract
- 1/4 teaspoon (1.25g) salt
Instructions:
- Preheat oven to 350°F (175°C). Grease and flour cake pans, then line the bottoms with parchment paper rounds.
- In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
- In a large bowl, cream together butter and sugar until light and fluffy.
- Beat in eggs one at a time, then stir in vanilla extract.
- Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined. Do not overmix.
- Divide the batter evenly among the prepared cake pans. Bake for 30-35 minutes, or until a cake tester inserted into the center comes out clean.
- Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
- In a heavy-bottomed saucepan, melt butter over medium heat. Add sugar and cook, stirring constantly, until sugar is melted and a deep amber color. Watch closely to prevent burning!
- Slowly pour in heavy cream, stirring constantly. The mixture will bubble vigorously. Continue to cook, stirring, until the caramel is smooth and thickened, about 2-3 minutes.
- Remove from heat and stir in vanilla and salt. Let cool slightly until spreadable.
- Place one cake layer on a serving plate or cake stand. Spread with a generous layer of caramel frosting. Repeat with remaining cake layers and frosting.
- Frost the top and sides of the cake with the remaining frosting. Swirl attractively.
