Instructions
- Step 1: Preheat your oven to 350°F (175°C) to prepare for baking your cake to golden perfection.
- Step 2: In a bowl, whisk together the flour, baking powder, baking soda, and salt until well combined.
- Step 3: In a separate bowl, beat the softened butter and granulated sugar together until light and fluffy, about 4 minutes.
- Step 4: Add the eggs one at a time, mixing well after each addition to achieve a smooth batter.
- Step 5: Stir in the buttermilk and vanilla extract until just combined and the batter is creamy.
- Step 6: Gradually fold in the dry flour mixture, being careful not to overmix for a tender cake texture.
- Step 7: Gently fold in the crushed toffee pieces and, if using, chopped pecans for added crunch.
- Step 8: Divide the batter evenly into prepared cake pans and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Step 9: Let the cakes cool in their pans for 10 minutes, then transfer them to wire racks to cool completely.
- Step 10: To make the caramel sauce, heat granulated sugar in a saucepan over medium heat, stirring constantly until it melts into a golden brown liquid.
- Step 11: Carefully add the cubed butter and stir until melted and incorporated, then slowly stir in the heavy cream and salt. Remove from heat and let cool.
- Step 12: For the frosting, beat the softened butter until smooth, then gradually add powdered sugar, caramel sauce, vanilla extract, and heavy cream. Continue beating until light and fluffy.
- Step 13: Spread the caramel frosting between the layers and over the top and sides of the cooled cake for a luscious finish.
Tips & Variations
- For extra flavor, toast the pecans before adding them to enhance their nuttiness.
- You can substitute crushed toffee with chopped caramel candies for a different texture.
- If you prefer a less sweet frosting, reduce the powdered sugar slightly or add a pinch of salt to balance flavors.
- Use store-bought caramel sauce to save time without compromising taste.
Storage
Store the cake covered in the refrigerator for up to 4 days to keep the frosting fresh. Let the cake come to room temperature before serving for the best texture and flavor. You can also freeze the cake layers (unfrosted) for up to 2 months and thaw before frosting.
How to Serve
Serve this delicious recipe with your favorite sides.
FAQs
Can I make this cake dairy-free?
Yes, substitute butter with a dairy-free alternative and use a plant-based milk mixed with lemon juice or vinegar instead of buttermilk. Choose dairy-free caramel sauce and cream substitutes for the frosting.
How do I prevent the toffee from sinking to the bottom?
Gently toss the crushed toffee pieces in a small amount of flour before folding them into the batter. This helps them stay suspended throughout the cake while baking.
