Frequently Asked Questions
- Why did my cake crack while rolling?
Roll the cake while still warm and in a towel dusted with powdered sugar. Cool completely before unrolling to add filling.
- Can I make this ahead of time?
Yes, prepare up to 2 days ahead and store covered in the refrigerator. Add ganache and sprinkles just before serving.
- Why is my ganache too thick?
Let ganache cool to room temperature before pouring. If too thick, warm slightly or add a touch more cream.
- Can I use different sprinkles?
Yes, but jimmies (rod-shaped sprinkles) work best as they won't bleed into the batter like nonpareils.
- How do I get clean slices?
Use a sharp knife dipped in hot water and wiped clean between cuts. Refrigerate cake until ganache is set.
