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

Preheat Oven: Set your oven to 350°F (175°C) to prepare for baking the cake until golden and cooked through.
Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, baking soda, and salt to evenly distribute leavening agents and seasoning.
Cream Butter and Sugar: In a separate bowl, beat the softened butter and granulated sugar until light and fluffy, which incorporates air for a tender crumb.
Add Eggs: Incorporate the eggs one at a time, mixing well after each to create a smooth, cohesive batter.
Add Wet Ingredients: Pour in the buttermilk and vanilla extract and blend until just combined, ensuring the batter is creamy but not overworked.
Combine Wet and Dry: Gradually fold the dry flour mixture into the wet ingredients gently to keep the batter light and tender.
Mix in Crunch Elements: Carefully fold in the crushed toffee and, if using, chopped pecans to infuse crunch throughout the batter.
Bake: Divide the batter evenly between prepared cake pans and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
Cool Cakes: Let the cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely before frosting.
Prepare Frosting: Beat the softened butter with powdered sugar, caramel sauce, vanilla extract, and heavy cream until the frosting is fluffy and smooth.
Assemble Cake: Spread the caramel frosting between cake layers and cover the top and sides generously, allowing it to drip artistically down the edges.

Notes

For a nut-free version, omit the chopped pecans.
To make caramel sauce, heat granulated sugar over medium heat until melted and golden, then stir in butter, cream, and a pinch of salt until smooth and cool before using.
The cake layers can be baked a day ahead and stored wrapped tightly to be frosted the next day.
Ensure the butter is softened, not melted, for both cake batter and frosting to achieve proper texture.
Use high-quality toffee bars for best flavor and crunch in the cake.
