These Lucky Charms cereal bars are a fun and delicious twist on the classic Rice Krispies Treats. They are a quick and easy no-bake dessert that’s perfect for St Patrick’s Day.
In a large Dutch oven over medium heat, melt the butter. Add the marshmallows and stir until the marshmallows are almost all melted. Turn the heat off and add the vanilla extract, then stir in the Lucky Charms and Rice Krispies by hand until combined.
Pour the cereal mixture into a lightly greased 9" x 13" baking dish. Using the back of a spoon, spread the mixture evenly into the baking dish. Lightly wet or spray your hands with nonstick cooking spray, then gently pat down the cereal bars.
Allow to cool at room temperature for at least 20 minutes, or until they hold their shape. Cut into 3" squares and enjoy!
