FAQs

Can I make this cake ahead of time?

Yes! You can bake the cake layers a day ahead and store them wrapped in plastic. Assemble and frost before serving.

What’s the best way to melt butterscotch chips?

Melt them in a microwave-safe bowl in 20-second intervals, stirring in between.

How do I prevent my caramel from crystallizing?

Use a clean pan, avoid stirring too much, and add a bit of corn syrup if needed.

Can I use store-bought caramel sauce?

Yes, but homemade caramel has a richer, fresher flavor.

Can I use salted butter instead of adding sea salt?

Yes, but adjust the amount of added salt to avoid making it too salty.

Why did my cake turn out dense?

Overmixing the batter or using too much flour can make it dense. Mix just until combined.

How do I make the frosting smoother?

Add a bit more heavy cream and beat until fluffy and smooth.

Can I use regular milk instead of buttermilk?

You can, but for best results, mix 1 cup of milk with 1 tablespoon of vinegar or lemon juice as a substitute.

What’s the best way to drizzle caramel sauce on the cake?

Use a spoon or piping bag to create a drip effect along the edges.
