How to Make Caramel Toffee Crunch Cake
1: Preheat and Prepare
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans and line the bottoms with parchment paper.
2: Make the Cake Batter
- In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- In another bowl, beat the softened butter and sugar until light and fluffy (about 3-4 minutes).
- Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- Gradually add the dry ingredients and buttermilk, starting and ending with the dry mixture. Mix until just combined.
3: Bake the Cakes
- Divide the batter evenly between the prepared pans. Smooth the tops with a spatula. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Cool the cakes in the pans for 10 minutes, then transfer to a wire rack to cool completely.
4: Make the Caramel Sauce
- Heat the granulated sugar in a saucepan over medium heat, stirring constantly until melted and amber-colored.
- Stir in the cubed butter until fully melted.
- Slowly pour in the heavy cream while continuing to stir. Add a pinch of salt and cook for 1-2 minutes until smooth. Let cool slightly.
5: Prepare the Frosting
- Beat the softened butter until creamy.
- Gradually add powdered sugar, mixing until smooth.
- Add 1/4 cup of caramel sauce and vanilla extract. Adjust the consistency with heavy cream if needed.
6: Assemble the Cake
- Place one cake layer on a cake stand. Spread a layer of frosting on top.
- Drizzle with caramel sauce and sprinkle toffee pieces.
- Place the second cake layer on top and frost the entire cake.
- Decorate with more toffee pieces and a final drizzle of caramel sauce.
7: Final Touches
- For an extra crunch, sprinkle chopped pecans on top and finish with a glossy caramel drizzle.
What to Serve with Caramel Toffee Crunch Cake
- Vanilla Ice Cream: A scoop of vanilla ice cream complements the warm caramel flavors.

Expert Tips for the Perfect Cake
