Creating Patriotic Star Rice Krispie Treats can be straightforward if you follow these simple steps:

1. Prepare Your Pan: Grease a 9×13 inch baking pan with cooking spray or butter.
2. Melt Butter: In a large pot over low heat, melt the unsalted butter.
3. Add Marshmallows: Once the butter is melted, add the mini marshmallows and stir continuously until completely melted.
4. Mix in Vanilla: Remove the pot from heat and stir in the vanilla extract until combined.
5. Add Rice Krispies: Gradually fold in the Rice Krispie cereal, mixing until evenly coated with the melted marshmallow mixture.
6. Separate Mixture: Divide the mixture into two bowls.
7. Color the Mixture: In one bowl, stir in a few drops of red food coloring until you achieve your desired shade. In the other bowl, do the same with the blue food coloring.
8. Layer Mixtures: In the prepared baking pan, layer the red Rice Krispie mixture evenly across the bottom. Press down firmly with a spatula or wax paper.
9. Add White Layer: Next, evenly spread the plain Rice Krispie mixture over the red layer, pressing down again firmly.
10. Top with Blue: Finally, spread the blue Rice Krispie mixture over the white layer, smoothing it out.
11. Cool: Allow the layered mixture to cool for about 15 minutes, or until set.
12. Cut Out Stars: Once cooled, use a star-shaped cookie cutter to cut out the treats. You can also use a knife to cut them into squares if preferred.
13. Decorate: Sprinkle the nonpareils or edible glitter on top for that extra patriotic flair.
