To shape red, white, and blue 4th of July Rice Krispie Treats into stars, you can use a star-shaped cookie cutter. Here's how to do it: After pressing the Rice Krispie mixture into the greased baking dish, allow it to cool for about 5-10 minutes. Use a star-shaped cookie cutter to cut out star shapes from the cooled Rice Krispie mixture. Gently remove the stars from the baking dish and place them on a baking sheet or platter. Melt white chocolate chips in a small saucepan over medium heat, and dip each star-shaped treat into the melted chocolate, covering the top and sides. Quickly sprinkle the patriotic sprinkles over the melted chocolate before it sets. Let the treats cool and the chocolate harden. Once the chocolate is set, insert a paper straw into the bottom of each star-shaped treat, creating a star-shaped Rice Krispie pop.
