Ingredients

Scale

Cake Ingredients

  • 2 1/2 cups all-purpose flour
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1 cup unsalted butter, softened
  • 1 1/2 cups granulated sugar
  • 4 large eggs
  • 1 cup buttermilk
  • 1 tsp vanilla extract
  • 1 cup crushed toffee pieces (e.g., Heath bars)
  • 1/4 cup chopped pecans (optional)

Frosting Ingredients

  • 1 1/2 cups unsalted butter, softened
  • 4 cups powdered sugar
  • 1/4 cup caramel sauce
  • 1 tsp vanilla extract
  • 2 tbsp heavy cream

Caramel Sauce Ingredients

  • 1 cup granulated sugar
  • 6 tbsp unsalted butter, cubed
  • 1/2 cup heavy cream
  • 1 pinch salt

Instructions

  1. Preheat oven: Preheat your oven to 350°F (175°C) so it’s ready to bake your cake to golden perfection.
  2. Mix dry ingredients: In a bowl, whisk together the flour, baking powder, baking soda, and salt until well combined to ensure even distribution of leavening agents.
  3. Cream butter and sugar: In another bowl, beat the softened butter and granulated sugar together until light and fluffy, about 4 minutes, which helps create a tender crumb.
  4. Add eggs: Incorporate eggs one at a time, mixing well after each addition to create a smooth, cohesive batter.
  5. Add buttermilk and vanilla: Pour in the buttermilk and vanilla extract, mixing until just combined to maintain cake tenderness and moisture.
  6. Combine batter and dry ingredients: Gradually fold the dry ingredients into the wet, being careful not to overmix to keep the cake tender.
  7. Add toffee and pecans: Gently fold in crushed toffee pieces and optional pecans, providing signature crunch and flavor.
  8. Bake the cake: Divide the batter evenly into prepared cake pans and bake for 30-35 minutes or until a toothpick inserted comes out clean, indicating doneness.
  9. Cool the cakes: Allow the cakes to cool in the pans for 10 minutes before transferring to wire racks to cool completely, which prevents the frosting from melting.
  10. Prepare frosting: Cream softened butter with powdered sugar, caramel sauce, vanilla extract, and heavy cream until fluffy to create a luscious caramel buttercream.
  11. Frost the cake: Spread the caramel frosting between cake layers and over the top, allowing it to cascade down the sides for a beautiful finish.

Notes

  • Be careful not to overmix the batter to maintain a tender crumb.
  • Allow cakes to cool completely before frosting to prevent melting.
  • For added flavor, try substituting pecans with walnuts or almonds.
  • Store leftover cake in an airtight container at room temperature for up to 2 days or refrigerated for up to 5 days.
  • If desired, warm caramel sauce slightly before mixing into frosting for easier blending.
