No Bake Butterscotch Cereal Bars

There are so many things to love about cereal bars like these, especially when they don’t require an oven and you can adapt them to use whatever cereal and baking chip combination you like!

This recipe was inspired by my rice krispie treats recipe, but I used cornflakes and added a little butterscotch flavor twist and some toasted coconut. They are soft, chewy and gooey from the delicious marshmallows.

How to make No Bake Butterscotch Cereal Bars:

  • Add cereal, marshmallows, butterscotch chips, and toasted coconut to a large bowl.
  • Melt butter and marshmallows in a saucepan; stir in butterscotch chips.
  • Pour over bowl with cereal and stir to coat.
  • Press into 13×9-inch baking pan with parchment paper and sprinkle coconut flakes on top.
  • Cool.

Make ahead, storing and freezing Instructions:

These cereal bars can be made 1-2 days in advance.  For best results, allow the to cool completely, cut them, wrap them individually in plastic wrap, and store them in an airtight container. Store at room temperature for 2-3 days or freeze in a freezer safe bag for up to 1 month.

  • Add nuts, M&M’s, or craisins.

Are cereal bars healthy?

These cereal bars are more of a dessert than a breakfast cereal bar.  The ingredients include cornflakes, marshmallows, butter, coconut, and butterscotch chips.
