How to serve Chocolate Caramel Toffee Crunch Cake

How to store Chocolate Caramel Toffee Crunch Cake

Tips & Tricks
- Use room temperature eggs for a smoother batter.
- Grease and flour pans well to release cakes cleanly.
- Add toffee just before serving if you want extra crunch.
- Warm the caramel slightly so it spreads easily between layers.
- If frosting is thick, thin it with a teaspoon of milk to spread smoothly.
Variations & Substitutions
- Swap whole milk for buttermilk for a tangy, tender cake.
- Use salted caramel for a sweet-salty flavor.
- Replace toffee bits with chopped nuts for different crunch.
- Use a boxed chocolate cake mix if you want a faster method.
FAQs
Q: Can I make this cake ahead of time?

Q: Can I freeze the cake?
A: Yes. Wrap baked and cooled layers tightly in plastic and foil. Freeze up to 2 months. Thaw in the fridge before assembling.
Q: Can I use store-bought frosting and caramel?
A: Yes. Store-bought products work well and save time.
