These colorful Fruit Loop Cereal Bars are a vibrant twist on classic Rice Krispie treats, made using just three ingredients—melty butter, gooey mini marshmallows, and Froot Loops cereal. In under 10 minutes, you can whip up a fun, fruity, and portable snack that’s perfect for kids, parties, lunchboxes, or any time you want a quick sweet treat. They’re easy to press into an even pan, let set, and cut into squares. Bright, chewy, nostalgic—and totally addictive. 

Ingredients

For the Bars:
3 Tbsp unsalted butter
12 oz mini marshmallows
6 cups Froot Loops cereal 

Directions

1. In a large pot over medium-low heat, melt the butter while stirring to prevent burning.
   
   

2. Add mini marshmallows and stir until nearly all are melted, then remove from heat.
   
   

3. Immediately stir in the Froot Loops until the cereal is evenly coated in the marshmallow mixture.
   
   

4. Press the mixture firmly into a greased or parchment-lined 8×8‑inch pan (use buttered plastic wrap or nonstick spray).
   
   

5. Let the mixture cool completely and refrigerate for at least one hour to firm up.
   
   

6. Slice into 16 bars and serve. Store at room temperature in an airtight container for 2–3 days.
