Instructions

Step 1: Preheat your oven to 350°F (175°C) so it’s ready to bake your cake to golden perfection.

Step 2: In a bowl, whisk together 2 1/2 cups flour, 1 tsp baking powder, 1/2 tsp baking soda, and 1/2 tsp salt until well combined.

Step 3: In another bowl, beat 1 cup softened butter and 1 1/2 cups granulated sugar together until light and fluffy, about 4 minutes.

Step 4: Incorporate 4 large eggs, one at a time, mixing well after each addition for a smooth batter.

Step 5: Pour in 1 cup buttermilk and 1 tsp vanilla extract, mixing until just combined and the batter is luxurious and creamy.

Step 6: Gradually fold the flour mixture into the wet ingredients, being careful not to overmix for a tender cake.

Step 7: Gently mix in 1 cup crushed toffee pieces and optional 1/4 cup chopped pecans for a delightful crunch.

Step 8: Divide the batter into prepared cake pans and bake for 30-35 minutes or until a toothpick comes out clean.

Step 9: Allow the cakes to cool completely in the pans for 10 minutes, then transfer to wire racks to cool fully.

Step 10: To make the caramel sauce, melt 1 cup granulated sugar in a saucepan over medium heat until golden and smooth. Carefully stir in 6 tbsp cubed butter until melted, then slowly add 1/2 cup heavy cream and a pinch of salt. Stir until fully combined and set aside to cool.

Step 11: For the frosting, cream 1 1/2 cups softened butter with 4 cups powdered sugar, 1/4 cup of the prepared caramel sauce, 1 tsp vanilla extract, and 2 tbsp heavy cream until fluffy and smooth.

Step 12: Spread the creamy caramel frosting between the cooled cake layers and then cover the top and sides evenly. Sprinkle extra crushed toffee pieces on top for an added crunch.

Step 13: Chill the cake in the refrigerator for at least 30 minutes before serving to set the frosting and enhance the flavors.

Tips & Variations

Use room temperature ingredients to ensure a smooth batter and even baking.

Substitute pecans with walnuts or skip nuts altogether if preferred.

For a stronger caramel flavor, drizzle additional homemade caramel sauce over the frosted cake before serving.

If you don’t have buttermilk, mix 1 tbsp lemon juice or vinegar into 1 cup milk and let it sit for 5 minutes before using.

Storage

Store the cake covered in the refrigerator for up to 4 days. Bring to room temperature before serving for the best texture and flavor. Leftover cake can also be wrapped tightly and frozen for up to 2 months; thaw overnight in the refrigerator before enjoying. Reheat slices gently in the microwave if desired.

FAQs

Can I make this cake gluten-free?

You can substitute the all-purpose flour with a gluten-free baking blend, but be mindful that the texture may vary slightly. Ensure your toffee pieces and caramel sauce are gluten-free as well.

How do I prevent the frosting from being too sweet?

Balance the sweetness by using salted butter in the frosting or slightly reducing the powdered sugar. Adding a pinch of salt to the frosting can also help mellow out the sweetness.
