FAQs About the Recipe
- → Can I use store-bought cream cheese for the filling?
You sure can. Block-style cream cheese, brought to room temp, mixes easiest and gives your cheesecake a silky finish.
- → What kind of sprinkles work best?
Stick with classic rainbow jimmies. They keep their color and won't melt or smear in your batter or icing.
- → Do I need to use a water bath for the cheesecake?
Using a water bath lets the cheesecake bake evenly and stay smooth, so it's not likely to crack.
- → Can I assemble the dessert ahead of time?
Definitely! Put the layers together and chill it overnight. It’ll slice cleaner and taste even better.
- → How do I achieve smooth, fluffy frosting?
Beat soft butter and cream cheese together really well, then add powdered sugar and vanilla until it turns light and fluffy.
