How To Make Shamrock Rice Krispie Treats
- Prepare a 9x13 pan with non-stick spray. Melt the butter in a large pot over medium heat. Add the marshmallows and stir until fully melted in the butter. Stir in the green food coloring.
- Remove the pot from the heat and stir in the rice cereal. Add to the prepared dish and press into the pan as much as you can. Place the pan in the fridge for 10 minutes to cool.
- Turn the pan upside down on top of a cutting board or counter. Use the cookie cutter to cut out as many shamrocks as you can.
- Use gel frosting and sprinkles to decorate the shamrocks with fun faces. Enjoy!
Tools Needed to Make These St. Patrick's Day Treats
Tips for Making Rice Cereal Shamrocks
- You can use regular marshmallows instead of lime and lemon-flavored marshmallows. Below is a photo of the marshmallows I used. You do have to separate the flavors, but my son and I had fun doing it!😁
- If you want your treats to have more flavor but don't have flavored marshmallows, try adding lime extract, almond extract, or vanilla extract!
- Make sure you use non-stick spray on your pan so the treats don't stick!
- You can also spray your hands with non-stick spray before pressing the treats into the pan so that they are nice and compact. This will make cutting out the shapes much easier.
- Get creative with your decorating and most importantly, have fun!
