Frequently Asked Questions
- → Is it okay to prepare this cake in advance?
Absolutely! You can get it ready 1-2 days before serving. Store it in the fridge, covered. The coffee flavor actually deepens as it sits.
- → What can replace Kahlua in this recipe?
If you'd rather skip Kahlua, try another coffee liqueur or strong brewed coffee for a booze-free option.
- → Why does the mascarpone frosting turn watery?
That can happen if the mascarpone becomes warm. Make sure to chill it and the heavy cream before mixing, and don’t overwhip.
- → Can I switch the brand of cake mix?
Betty Crocker’s white cake mix (16.25 oz) works great, but you can try another as long as the weight matches that amount.
- → What's the best way to save leftover slices?
Pop leftovers into an airtight container and store them in the fridge for up to four days. For best taste, let it warm to room temp for 20 minutes before eating.
