Equipment
- 9x13-inch baking pan
- Large Bowl
- Large saucepan
Ingredients
- 1 package white or yellow cake mix (about 15.25 oz)
- 1/2 cup unsalted butter (1 stick), softened
- 1 large egg
- 10 drops green food dye (or as desired)
- 4 cups miniature marshmallows (plus 1/3 cup reserved from cereal)
- 1/3 cup light corn syrup
- 3 Tablespoons unsalted butter
- 1 1/2 cups white chocolate chips
- 1 teaspoon vanilla extract
- 1 1/2 teaspoons salt
- 5 cups Lucky Charms cereal
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch baking pan with non-stick spray.
- In a large bowl, combine the cake mix, the 1/2 cup softened butter, the egg, and about 10 drops of green food dye (or more for a vibrant color). Mix on low speed until the ingredients are just combined and form a moist, crumbly mixture.
- Gently press this mixture evenly into the bottom of your prepared pan. Bake for 20 minutes.
- Carefully remove the pan from the oven and immediately sprinkle the 4 cups of miniature marshmallows all over the warm cake base. Pop the pan back into the oven for an additional 3 minutes, just until the marshmallows begin to puff up and soften slightly.
- While the marshmallows are baking, grab a large saucepan. Add the corn syrup, the 3 Tablespoons of butter, and the white chocolate chips. Cook over medium-low heat, stirring continuously, until the chocolate chips are completely melted and the mixture is smooth. Remove the saucepan from the heat, then stir in the vanilla extract and salt.
- Take out 1/3 cup of the colorful marshmallows from your 5 cups of Lucky Charms cereal and set them aside. Pour the remaining Lucky Charms cereal into the warm white chocolate mixture in the saucepan and stir quickly until the cereal is well coated.
- Working quickly, spoon the warm cereal topping evenly over the marshmallow layer in your pan, spreading it out to cover completely. Immediately sprinkle the reserved 1/3 cup of Lucky Charms marshmallows on top, lightly pressing them down so they stick.
- Allow the bars to cool completely at room temperature or chill them in the refrigerator until firm. Once cooled, cut into squares and enjoy your festive treats! Store any leftovers covered.
