In your microwave-safe bowl, add the 1/2 tbsp of unsalted butter. Microwave it for about 20-30 seconds until fully melted. Keep an eye on it to avoid any splattering.
Once the butter is melted, add the 1/2 cup of mini marshmallows to the bowl. Stir to coat them in the melted butter, then return the bowl to the microwave.
Microwave the marshmallow and butter mixture for an additional 30 seconds. After this, stir the mixture until the marshmallows are fully melted and smooth. If necessary, you can microwave for an additional 10 seconds at a time until completely melted.
Once the marshmallows are melted, add in the 1/2 cup of Rice Cereal. Stir until all the cereal is coated with the marshmallow mixture.
Transfer the mixture into your prepared 9x9-inch baking dish. Use a spatula or your hands (dampened to prevent sticking) to firmly press the mixture into an even layer.
Allow the treats to cool for about 15-20 minutes until set. Once they’re firm, cut them into squares and enjoy your delicious Rice Krispie Treats!
