Frequently Asked Questions
Do I really not stir anything?
Correct. Layering is essential—stirring ruins the magic.
Can I use fresh fruit instead of frozen?
Frozen works best. Fresh fruit releases less liquid and won’t create the same syrupy base.
What Jell-O flavor works best?
Strawberry is classic, but any flavor works—this recipe is endlessly customizable.
Can I make this ahead of time?
Yes. Reheat gently in the oven or microwave before serving.
Is this cake supposed to look messy?
Absolutely. This is a spoon-dessert, not a slice-perfect cake.
How to Store
Cover and refrigerate leftovers for up to 3 days. Reheat before serving for best texture.
How to Freeze
Freezing is not recommended—the marshmallow and gelatin textures don’t thaw well.
