There is something so special about the way these bright cereal pieces pop against the gooey marshmallow base. They are a absolute favorite in my kitchen whenever we need a quick sweet treat that makes everyone smile.

My best tip is to stir in the final two cups of cereal after the mixture has cooled down for just a minute. This keeps the marshmallows in the cereal from melting away, so you get that signature crunch in every single bite.

🧺 Ingredients

4 tablespoons unsalted butter
10 ounces mini marshmallows
6 cups Lucky Charms cereal, divided
1/4 teaspoon vanilla extract

👩‍🍳Instructions

1
Grease a 9 by 9 inch baking pan with butter or nonstick cooking spray.
2
Melt the butter in a large pot over low heat until it is completely liquid.
3
Add all of the marshmallows to the pot and stir constantly until they are fully melted and smooth.
4
Remove the pot from the heat and stir in the vanilla extract.
5
Gently fold in 4 cups of the cereal until it is evenly coated in the marshmallow mixture.
6
Fold in the remaining 2 cups of cereal quickly so they hold their shape.
7
Press the mixture into your prepared pan using a piece of wax paper or a greased spatula.
8
Let the bars cool at room temperature for about one hour before you slice them into squares.

💡 Tips

Store these in an airtight container at room temperature for up to three days. You can press a few extra marshmallows on top right after you spread the mixture into the pan to make them look extra festive.
