- Pair with a strong coffee or a cold glass of milk.
- Add fresh berries for a tart contrast.
- Drizzle with caramel for extra decadence.
Common Mistakes to Avoid
- Cake isn’t fully cooled before adding ice cream. This can cause the ice cream to melt unevenly.
- Ice cream is too soft when spreading. It should be spreadable but not runny.

Storage Tips
