No-Bake Chex Bars

Line a 9x9-inch pan with aluminum foil or parchment paper and spray it with non-stick spray.

In a large bowl, toss together the pretzels, Chocolate Chex, and mini M&M's.

In a medium saucepan over low heat, melt the butter and peanut butter together. Turn off the heat and mix in the marshmallow fluff until smooth and well combined.

Pour the marshmallow fluff mixture over the pretzel and Chex mixture in the bowl. Stir with a wooden spoon to coat the dry ingredients evenly.

Transfer the mixture into the prepared pan and press it out with your hands, smoothing it into an even layer. If the mixture sticks to your hands, wet them slightly to make pressing easier.

Cover the pan with plastic wrap and refrigerate the bars until firm, for at least 2 hours or until set.

Once the bars are firm, remove them from the refrigerator. Use the foil or parchment paper overhang to lift the bars out of the pan and place them on a cutting board.

Cut the chilled mixture into 9 squares, using a sharp knife.

Store the No-Bake Chex Bars in the refrigerator in an airtight container, where they can be kept for up to a week.
