Ingredients

Scale

Cake

  • 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

  • 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

  • 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 rising and flavor balance.
  3. Cream Butter and Sugar: In another bowl, beat softened butter with granulated sugar until light and fluffy, about 4 minutes, which creates a tender crumb in the cake.
  4. Add Eggs: Incorporate the eggs one at a time, mixing well after each addition to achieve a smooth, uniform batter.
  5. Add Buttermilk and Vanilla: Pour in buttermilk and vanilla extract, mixing until just combined for moisture and a subtle tang.
  6. Combine Wet and Dry Ingredients: Gradually fold the dry flour mixture into the wet ingredients carefully to avoid overmixing, which helps maintain cake tenderness.
  7. Add Toffee and Pecans: Gently fold in crushed toffee pieces and chopped pecans if using, providing signature crunch and nuttiness.
  8. Bake Cake: Divide the batter evenly between prepared cake pans and bake for 30-35 minutes or until a toothpick inserted comes out clean, signaling doneness.
  9. Cool Cake: Let the cakes cool in the pans for 10 minutes before transferring to wire racks to cool completely, preventing sogginess.
  10. Make Frosting: Cream softened butter with powdered sugar, caramel sauce, vanilla extract, and heavy cream until fluffy and smooth for a decadent finish.
  11. Assemble Cake: Spread the creamy caramel frosting between the cool cake layers to build the cake.
  12. Finish and Serve: Frost the entire cake with remaining frosting, decorate if desired, then slice and serve to enjoy the rich caramel-toffee delight.

Notes

  • Use room temperature butter and eggs for better mixing and texture.
  • Ensure the cakes are completely cool before frosting to prevent melting.
  • Crushed toffee bars can be substituted with your favorite toffee candy.
  • Chopped pecans are optional but add a nice crunch and flavor dimension.
  • Store leftovers in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
