Cereal marshmallow treats will have you feeling a little nostalgic. These no-bake dessert bars are filled with your favorite sugary childhood cereal and gooey marshmallows.
Who else gets a little nostalgic walking down the cereal aisle? Next time you're at the grocery store, grab a box of your favorite childhood cereal and make a batch of cereal marshmallow treats!
These no-bake treats can be made with just about any brand of cereal - make them fruity or chocolatey! Chewy, gooey, and sweet - the entire family will love them.
Cereal marshmallow treats are so easy to make that the kids can help. Make a batch on the weekend, for a picnic or barbecue, or as a last-minute school treat.
Ingredients and substitutions
- Cereal - Grab six cups of your favorite cereal - Honey Smacks are shown, but check out my full list of cereal options below, which includes Fruity Pebbles, Reese's Puffs, and more.
- Mini marshmallows - I prefer mini marshmallows because they melt easily and quickly, but regular marshmallows will also work.
- Butter - Salted butter can be substituted with unsalted butter and a pinch of salt. A bit of salt in this recipe helps balance the sweetness and enhances the flavor of whatever cereal you choose.
The great part about this recipe is that it can be made with just about any type of cereal. My suggestion? Rice Krispies, Cocoa Krispies, and Fruity Pebbles add the best texture.
However, this recipe will work with just about any cereal out there! Here are a few more ideas:
- Corn Flakes
- Frosted Flakes
- Cocoa Krispies
- Fruity Pebbles
- Rice Krispies
- Golden Grahams
- Fruit Loops
- Reese's Puffs
Try combining several of your favorite cereals into a single batch! Make a fruity cereal bar with Fruit Loops and Fruity Pebbles, or a chocolatey bar with Reese's Puffs and Cocoa Krispies.
Frequently asked questions
They're best enjoyed within 1 to 2 days of preparing and dry out quickly after that. Store prepared treats in a tightly sealed container at room temperature.
Yes, cereal marshmallow treats freeze well, up to six weeks or more when stored in optimal conditions. I suggest tightly wrapping your treats in foil, then storing in a tightly sealed freezer-safe container or bag.
Marshmallows can be substituted with a jar of marshmallow fluff. The butter and marshmallows could also be substituted with ¾ cup of peanut butter and ¾ cup of honey heated over medium heat until melted and smooth, similar to the base of scotcheroos. Peanut butter works best with neutral cereals like Frosted Flakes and Rice Krispies, or chocolate cereals like Reese's Puffs and Cocoa Krispies.
