- No mixing up ingredients, simply layer and bake.

Ingredients and Variations
BASE: Peanut butter cookie dough is the perfect base for these magic cookie bars, but any pre-made cookie dough will work. Sugar cookie, chocolate chip, even an oatmeal cookie dough base sounds delish!
Swap out the peanut butter cookie base for either a graham crust or a chocolate base.
TOPPINGS: Oreos, chocolate chunks, peanut butter chips, and toffee bits are our toppings of choice! Nuts and/or coconut can replace some or all of the Reese’s Pieces.
How to Make Peanut Butter Magic Bars
- Press peanut butter cookie dough in the bottom of a prepared baking dish & bake.
- Sprinkle half the crushed cookie pieces, chocolate chunks, peanut butter chips, & toffee bits over the cookie layer.
- Pour sweetened condensed milk over the top of the magic bars. Top with remaining crushed Oreo cookies & sprinkle on Reese’s pieces.
- Bake per recipe below until the sweetened condensed milk turns a caramel brown color.
Remove magic bars & let them cool for 2 hours before cutting. These bars are rich so we like to cut them into small pieces.
PRO TIP: It’s easier to cut these into bars by lifting the entire sheet out on a large cutting board. Then simply use a sharp knife to create evenly sized bars.
How to Store
- Keep peanut butter magic bars in an airtight container for up to 4 days.
- Freeze cooled and cut bars in zippered bags to pop out whenever a snack attack hits, they thaw in just a few minutes if cut individually.
