Step-by-Step Instructions
Step 1: Prepare Your Baking Pans
Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans and line them with parchment paper. Pro tip: A light dusting of flour will ensure nothing sticks to the pan, giving you perfect cake layers.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, salt, and cocoa powder (if making the Chocolate Caramel variation). Whisking ensures even distribution of leavening agents for a perfectly textured Crunch Cake.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the butter and sugar until light and fluffy, about 3-4 minutes. This step incorporates air into the batter, creating a tender crumb that’s essential for our Caramel Crunch masterpiece.
Step 4: Add Eggs and Vanilla
Add eggs one at a time, mixing well after each addition. Stir in the vanilla extract. Don’t rush this step – proper incorporation now means a better texture later.
Step 5: Alternate Wet and Dry Ingredients
Gradually add the dry ingredients to the butter mixture, alternating with buttermilk. Begin and end with the dry ingredients, mixing just until combined. Overmixing at this stage can make your Decadent Dessert tough rather than tender.
Step 6: Bake the Cake
Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean with a few moist crumbs.
Step 7: Cool and Assemble
Allow cakes to cool in pans for 10 minutes, then transfer to wire racks to cool completely. Once cooled, place one layer on your serving plate and spread with caramel sauce, then sprinkle generously with toffee bits.
Step 8: Frost and Decorate
Whip the cream cheese, powdered sugar, and remaining caramel sauce until smooth. Fold in whipped heavy cream for a lighter texture. Frost the cake and decorate with additional toffee bits for that signature Caramel Toffee crunch.

Common Mistakes to Avoid

- Overmixing the batter (leads to a dense cake)

- Opening the oven door too early (causes cake to sink in the middle)
