Before You Bake

Do I need to press the bars firmly into the pan?
No, pressing too hard makes the bars dense. Lightly press them into an even layer so they stay soft, chewy, and easy to bite.

Can I melt the butter and marshmallows in the microwave?
Yes, but keep the heat low and stir every 20–30 seconds to prevent scorching. The stovetop gives better control for even melting.

Do these need to be refrigerated?
No, they’re best stored at room temperature. Refrigerating can make them hard instead of soft and chewy.

Ingredients

Scale 1x2x3x

• 6 cups Cinnamon Toast Crunch cereal
• 1 stick (½ cup) salted butter
• 1 bag (10 oz) mini marshmallows
• 1 teaspoon vanilla extract
• ½ teaspoon cinnamon
• Pinch of salt
• ½ cup white chocolate chips
• ½ cup crushed Golden Oreos (about 5–6 cookies)
• ¼ cup rainbow sprinkles, plus extra for topping

Instructions

1. Line an 8×8-inch pan with parchment paper and spray with nonstick spray, leaving some overhang for easy lifting.
2. In a large pot over low heat, melt the butter completely. Stir in cinnamon until fragrant, about 30 seconds.
3. Add marshmallows and stir until smooth and melted. Remove from heat and mix in vanilla and salt.
4. Quickly fold in the Cinnamon Toast Crunch cereal until fully coated. Gently stir in crushed Oreos, white chocolate chips, and sprinkles.
5. Transfer to the prepared pan and lightly press into an even layer using greased spatula or fondant smoother. Avoid pressing too firmly to keep the bars soft and chewy.
6. Sprinkle more rainbow sprinkles on top for that birthday look.
7. Let cool at room temperature for at least 1 hour, then lift from the pan and cut into large squares.

FAQ

How do I keep cereal treats soft?
Use fresh marshmallows and avoid overcooking them. Once melted, remove from heat immediately before mixing in the cereal.

Can I make these ahead of time?
Yes! They stay soft for up to 3 days in an airtight container. If making for a party, prepare the night before.

Can I double the recipe?
Absolutely. Use a 9×13-inch pan for a double batch and increase cooling time slightly.

Can I use different cereals or cookies?
Definitely! Try Fruity Pebbles for a colorful twist or vanilla wafers instead of Oreos for a lighter crunch.

Can I add chocolate drizzle on top?
Yes, a white or milk chocolate drizzle adds a fun finishing touch- just melt and drizzle once the bars are set.
