How to Make a Butterscotch Crunch Cake

Step 1: Prepare the Cake Batter
- Start by heating your oven to 350°F (175°C) and prepare two 9-inch round cake pans by greasing and flouring them.
- In a medium bowl, combine the flour, baking powder, baking soda, and salt, whisking them together.
- In a larger bowl, beat the softened butter and brown sugar until the mixture is light and fluffy.
- Add the eggs one at a time, ensuring to mix well after each addition. Then, stir in the vanilla extract.
- Slowly incorporate the flour mixture into the butter mixture, adding it in three parts, alternating with the buttermilk. Make sure to start and end with the dry ingredients.
- Gently fold in the sour cream, chopped butterscotch chips.
- Pour the batter evenly into the prepared pans and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cakes cool in the pans for about 10 minutes, then transfer them to a wire rack to cool completely.
Step 2: Make the Butterscotch Frosting
- In a saucepan over medium heat, melt the butter until fully liquefied. Stir in the brown sugar and heavy cream, and bring to a simmer.
- Cook for 2-3 minutes, stirring constantly, then remove from heat and allow to cool slightly.
- Slowly mix in the powdered sugar, vanilla extract, and salt, beating until the texture becomes light and creamy.
- If the frosting is too thick, stir in a tablespoon of milk at a time until you achieve the perfect consistency.
Step 3: Assemble the Cake
- Place one cake layer on a serving plate and spread a generous layer of butterscotch frosting over the top.
- Set the second cake layer over the first, then spread the remaining frosting evenly over the top and sides.
Step 4: Make the Butterscotch Crunch Topping
- In a small saucepan, melt the butterscotch chips over low heat, stirring constantly until smooth.
- In a separate bowl, combine the crushed cornflakes (or rice cereal) and toasted pecans (optional).
- Once the butterscotch chips are melted, pour them over the cereal mixture and stir to combine.
- Spoon the butterscotch crunch mixture over the top of the cake, pressing it gently to adhere.

Pro Tips for the Perfect Butterscotch Crunch Cake
- Use room temperature ingredients: Allow your butter and eggs to reach room temperature before using them. This ensures they mix evenly, creating a smoother batter.
- Toast the pecans: Toasting the nuts brings out their natural flavor and adds extra crunch to your cake.
- Avoid overmixing the batter: Overmixing can lead to a heavy cake. Stir until just combined to maintain a light and airy texture.
- Let the frosting cool before using: If your frosting is too warm, it may slide off the cake. Allow the frosting to cool to the desired consistency before spreading it on the cake.
Delicious Variations
- Chocolate Butterscotch Crunch Cake: Add 1/2 cup of cocoa powder to the cake batter for a chocolate twist.
- Maple Butterscotch Cake: Substitute the brown sugar for maple syrup to add a cozy, fall-inspired flavor.
- Nut-Free Version: Replace the pecans with toasted coconut flakes for a nut-free alternative.
- Butterscotch Cupcakes: Turn this recipe into cupcakes by dividing the batter into muffin tins and adjusting the baking time to 18-20 minutes.

Make sure the butterscotch chips are melted well before mixing them with the cereal, as this helps it adhere more effectively to the cake.
