1 9x3 baking pan
1 small sauce pan
1 medium sized mixing bowl
Ingredients
3cupsRice Krispies cereal
3cupsLucky Charms cereal
5tablespoonunsalted butter
10ouncesmarshmallowsfresh
Instructions
Start by lining the sides and bottom of a 13-inch pan with parchment paper. Measure the Rice Krispies and Lucky Charms cereal, combine them in a large bowl, and set aside.
In a large saucepan over medium-low heat, melt the butter and marshmallows, stirring constantly, until the marshmallows are completely melted and smooth.
Pour the marshmallow mixture over the cereal mixture and gently stir until all of the cereal is evenly coated.
Transfer the mixture into the prepared pan. Use a small piece of wax paper or lightly greased hands to gently press the cereal mixture into the pan until an even layer forms.
While the mixture is still warm, sprinkle additional Lucky Charms cereal over the top and gently press it in so it sticks.
Let cool completely for 30 minutes to 1 hour.
Lift the cereal treats out of the pan using the parchment paper, place them on a cutting board, and cut into 24 even squares.
Notes
Expert Tips
Always melt the butter and marshmallows over medium-low heat. High heat can overcook the sugar, causing the Rice Krispies treats to turn hard instead of soft and chewy.
Remove the marshmallow mixture from the heat as soon as it becomes smooth. Overcooking leads to dry, stiff cereal bars once cooled.
Lightly press the cereal mixture into the pan just until even. Pressing too firmly compacts the cereal, resulting in dense, hard bars.
Fresh marshmallows melt smoothly, creating a soft texture. Stale marshmallows can melt unevenly and cause tough or crumbly treats.
Sprinkle extra Lucky Charms cereal on top while the mixture is still warm so it sticks properly. Waiting too long will prevent the garnish from adhering.
Line the pan with parchment paper. Parchment paper prevents sticking, makes removal easier, and helps create clean, even cuts.
For clean slices, cut the bars once they are set but still slightly soft. Waiting too long can cause cracking or uneven edges.
