How to Make Caramel Toffee Crunch Cake – Step by Step
Preparing the Cake Layers
Step 1: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line with parchment paper for easier removal.
Step 2: In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
Step 3: In a large mixing bowl, beat the softened butter and sugar together until light and fluffy, about 3-5 minutes. Don’t rush this step – the air incorporated here creates a tender crumb!
Step 4: Add eggs one at a time, beating well after each addition. Scrape down the sides of the bowl as needed.
Step 5: Mix in the vanilla extract.
Step 6: Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk, beginning and ending with the dry ingredients (divide dry ingredients into thirds and buttermilk in half). Mix just until combined after each addition.
Step 7: Divide the batter evenly between the prepared cake pans, smoothing the tops with a spatula.
Step 8: Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
Step 9: Cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Making the Homemade Caramel Sauce
Step 1: In a medium, heavy-bottomed saucepan, combine the sugar and water. Heat over medium heat without stirring (swirl the pan gently if needed).
Step 2: Once the sugar mixture turns amber (about 8-10 minutes), immediately remove from heat.
Step 3: Carefully add the heavy cream – it will bubble vigorously, so stand back! Stir until smooth.
Step 4: Add the butter, salt, and vanilla, stirring until fully incorporated.
Step 5: Allow the caramel to cool completely before using. It will thicken as it cools.
Preparing the Toffee Crunch
Step 1: In a small bowl, combine the toffee bits and chopped pecans (if using).
Step 2: Set aside about ⅓ cup for decorating the top of the cake.
Making the Caramel Frosting
Step 1: In a large bowl, beat the softened butter until light and creamy, about 2 minutes.
Step 2: Gradually add the powdered sugar, 1 cup at a time, beating well after each addition.
Step 3: Add ⅓ cup of your cooled caramel sauce, vanilla extract, and salt. Beat until well combined.
Step 4: Add the heavy cream 1 tablespoon at a time until you reach your desired consistency – it should be smooth and spreadable.
Assembling the Cake
Step 1: Place one cake layer on your serving plate or cake stand. Spread a thin layer of caramel sauce over the top.
Step 2: Sprinkle about half of your toffee crunch mixture over the caramel layer.
Step 3: Add a generous layer of caramel frosting on top of the toffee crunch.
Step 4: Place the second cake layer on top.
Step 5: Frost the top and sides of the cake with the remaining caramel frosting.
Step 6: Drizzle additional caramel sauce around the edges, allowing it to drip down the sides for a dramatic effect.
Step 7: Sprinkle the reserved toffee crunch mixture on top of the cake, focusing on the center or around the edges for a beautiful presentation.

Pro Tips for the Best Caramel Toffee Crunch Cake
- Room temperature ingredients: This is non-negotiable for a perfectly textured cake! Set out your butter, eggs, and buttermilk at least 30 minutes before starting.
- Don’t rush the caramel: Watch the sugar mixture closely as it cooks. The perfect amber color happens quickly, and it can burn in seconds if you’re not careful.
- Make ahead components: You can prepare the caramel sauce up to a week in advance and store it in the refrigerator. Just warm it slightly to make it pourable again.
- Cake insurance: If your cake layers dome too much during baking, gently trim the tops with a serrated knife to create flat surfaces for stacking.
- Frosting barrier: Create a “dam” of frosting around the edge of your cake layer before adding the caramel filling to prevent it from seeping out the sides.
- Chill for clean cuts: For picture-perfect slices, refrigerate the cake for 30 minutes before serving.
