Remove the pot from heat and immediately mix in the Rice Krispies cereal until well coated.

Press the mixture firmly into a 9x13 inch baking pan lined with parchment paper or lightly greased. Flatten it evenly across the pan.

Let the Rice Krispie treat cool and set in the refrigerator for at least one hour.

Cutting the Treats: Once set, lift the whole treat out of the pan using the edges of the parchment paper. Place it on a cutting board and cut into squares or rectangles to your preferred size.

Melting the Candies: Separately melt the red, white, and blue meltable candies according to the package instructions. Use bowls deep enough for easy dipping.
