Method
Prep pan
- Grease a 9x13-inch pan and line it with parchment paper so the bars lift out cleanly.
Make and press the red layer
- Melt 2 tablespoons butter with 4 cups mini marshmallows over low heat for 3-4 minutes until smooth, then tint with red gel food coloring.
- Fold in 4 cups rice krispie cereal and press the mixture into the bottom of the prepared pan to form an even layer.
Add the white layer
- Melt another 2 tablespoons butter with 4 cups mini marshmallows over low heat for 3-4 minutes until smooth (leave untinted).
- Fold in 4 cups rice krispie cereal and press the white layer evenly over the red layer.
Add the blue layer
- Melt the remaining 2 tablespoons butter with the final 4 cups mini marshmallows over low heat for 3-4 minutes until smooth, then tint with blue gel food coloring.
- Fold in the remaining 4 cups rice krispie cereal and press the blue layer evenly over the white layer.
Finish and set
- Drizzle the melted white chocolate over the top in a zigzag pattern.
- Let the bars set for at least 30 minutes before slicing into squares so the layers hold.
Notes
For the cleanest slices, chill just until firm (about 30 minutes), then use a sharp knife wiped between cuts. Store covered at room temperature for up to 2 days, or refrigerate up to 5 days; freeze for up to 1 month in a sealed container. For a halal-friendly swap, use halal-certified chocolate chips and ensure your gel food coloring is free of alcohol-based ingredients.
