FAQs

Can I use regular marshmallows instead of mini?

Yes, just chop them into smaller pieces or melt them fully. Use about 40 large marshmallows for this recipe.

Is it safe to eat raw cake mix?

Technically, raw cake mix may contain untreated flour. You can toast the cake mix in the oven at 350°F for 5 minutes to be safe, but it’s typically not an issue in no-bake treats when mixed with heated ingredients.

Can I use other cake mixes?

Yes, vanilla or yellow cake mix works well if you want a similar flavor without the sprinkles.

Can I double the recipe?

Absolutely. Use a larger pan or two 9×13 pans to accommodate the batch.

What’s the best way to press the mixture into the pan?

Lightly butter your hands or use a piece of wax paper to prevent sticking when pressing the mixture into the pan.

Can I make these in advance?

Yes, they’re great for making a day ahead and storing in a sealed container.

Do I need to refrigerate them?

No, room temperature is ideal to keep them soft and chewy.

Are they kid-friendly?

Very! They’re colorful, sweet, and perfect for little hands to help make or eat.

Can I reduce the sugar?

Using fewer marshmallows or cake mix will alter the texture and flavor. Stick to the original for best results.

Do I need to cook the cake mix before using it?

For peace of mind, you can toast the cake mix briefly in the oven. This is optional but recommended if you’re concerned about raw flour.
