Ingredients:
- 2 ½ cups (300g) all-purpose flour, plus more for dusting
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup (2 sticks / 226g) unsalted butter, browned and cooled slightly
- 1 ¾ cups (350g) granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup (240ml) buttermilk
- 1 cup (2 sticks / 226g) unsalted butter
- 1 cup (200g) packed light brown sugar
- ½ cup (120ml) heavy cream
- ¼ teaspoon salt
- 3-4 cups (360-480g) powdered sugar, sifted
Instructions:
- Preheat oven to 350°F (175°C). Grease and flour two 9-inch cake pans. Line the bottoms with parchment paper rounds.
- Melt butter in a saucepan over medium heat. Cook until golden brown and nutty-smelling. Let cool slightly.
- Whisk together flour, baking powder, baking soda, and salt in a bowl.
- In a stand mixer, cream together browned butter and granulated 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 buttermilk, beginning and ending with the dry ingredients. Mix until just combined. Do not overmix.
- Divide batter evenly between prepared pans. Bake for 30-35 minutes, or until a cake tester inserted into the center comes out clean.
- Let cakes cool in pans for 10 minutes before inverting onto a wire rack to cool completely.
- In a saucepan, melt butter over medium heat. Add brown sugar, heavy cream, and salt. Bring to a simmer, stirring constantly, until sugar is dissolved.
- Continue to simmer, without stirring, for 2 minutes.
- Remove from heat and let cool slightly (about 5-10 minutes).
- Gradually whisk in sifted powdered sugar until smooth and creamy. Add more or less powdered sugar to reach desired consistency.
- Place one cake layer on a serving plate. Spread with a generous layer of caramel icing. Top with the second cake layer and spread with remaining icing.
- Let the icing set slightly before slicing and serving.
