Instructions
Rice Krispies Treats
Grease a 9 inch by 13-inch baking pan, a large mixing bowl, and a silicone spatula or wooden spoon with butter or baking spray.
Pour the Rice Krispies Cereal into the large mixing bowl.
Begin melting the butter in a medium-large saucepan set over low heat, then stir in the marshmallows.
Continue to melt, stirring often, until about 75% of the marshmallows have melted.
Remove the pan from the heat and stir vigorously until all of the marshmallows have melted. This will give your treats a perfectly chewy (not hard) texture!
Pour the melted marshmallows over the Rice Krispies Cereal and toss to evenly coat.
Spread the mixture into the buttered pan and gently press into an even layer.
Let the cereal treats cool for at least 30 minutes before cutting them into 18 rectangles. If you want perfectly-shaped rectangles, trim off about ¼-inch around the edges of the treats.
Decorations
Pipe or spread a thin layer of blue frosting over one of your cereal treats, then pipe a few dabs or streaks of white and black food coloring over top.
Use an offset spatula or small spoon to swirl the frosting colors together making your treat look like the night sky.
Immediately, while the frosting is soft, decorate it by adding edible glitter stars, galaxy sprinkles, and planet, moon, or star-shaped icing decorations.
Repeat, decorating all of your treats.
Notes
Store your galaxy rice crispy treats in a single layer in an airtight container at room temperature for up to 5 days. Do not stack these treats unless you decorate them with icing that hardens or dries firm.
