Ingredients

Scale
  • 2 1/4 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1 cup (2 sticks) unsalted butter, softened
  • 1 3/4 cups granulated sugar
  • 4 large eggs
  • 1 tablespoon vanilla extract
  • 1 cup whole milk
  • For the Caramel Sauce: 1 cup granulated sugar
  • 1/2 cup heavy cream, warmed
  • 4 tablespoons unsalted butter, cut into pieces
  • 1/4 teaspoon salt
  • For the Toffee Crunch: 1/2 cup granulated sugar
  • 2 tablespoons water
  • 1/4 cup chopped pecans or almonds
  • 1/4 cup heavy cream, chilled
  • 1/2 cup powdered sugar (for frosting, if making)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans.
  2. Whisk together the flour, baking powder, and salt in a medium bowl. Set aside.
  3. In a large bowl, beat the softened butter and granulated sugar with an electric mixer until light and fluffy.
  4. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  5. Gradually add the dry ingredients alternately with the milk, beginning and ending with the dry ingredients. Mix until just combined. Do not overmix.
  6. Divide the batter evenly between the prepared pans. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
  7. Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
  8. Make the Caramel Sauce: Combine 1 cup sugar in a heavy-bottomed saucepan over medium heat. Cook without stirring until the sugar dissolves and turns a deep amber color.
  9. Remove the pan from the heat. Carefully whisk in the warm heavy cream (it will bubble vigorously). Whisk in the butter pieces and salt until smooth. Let cool slightly.
  10. Make the Toffee Crunch: Line a baking sheet with parchment paper. Combine 1/2 cup sugar and water in a small saucepan over medium heat. Cook until the sugar dissolves and turns amber.
  11. Stir in the chopped nuts. Pour the mixture onto the prepared baking sheet. Let cool completely until hard.
  12. Once cool, break the toffee into small, irregular pieces. Gently fold the broken toffee pieces into a simple buttercream or whipped cream frosting, if using.
  13. Assemble the cake: Place one cooled cake layer on a serving plate. Drizzle generously with caramel sauce. Top with the toffee crunch frosting (or plain frosting mixed with crunch). Place the second layer on top.
  14. Frost the top and sides of the cake with remaining frosting, if desired. Drizzle the top heavily with the remaining caramel sauce and sprinkle with extra toffee pieces for garnish.

Notes

  • For a moister cake, you can substitute buttermilk for the whole milk.
  • If you prefer a simpler crunch, use store-bought toffee bits instead of making your own.
  • The caramel sauce thickens as it cools; warm it slightly before drizzling for a better flow.
