A peanut butter cookie base is topped with chocolate chunks, peanut butter chips and of course sweetened condensed milk. It’s all baked up into the perfect decadent treat.

What are Magic Bars?

Magic bar recipes are any combination of a base like a cookie dough or a graham crust, then a mixture of toppings and sweetened condensed milk, and then baked to gooey perfection! They’re mix-and-match magic! This version is the perfect combination of peanut butter cookies and chocolate.

  • This is a quick and easy cookie bar recipe that comes together quickly.
  • No mixing up ingredients, simply layer and bake.
  • Mix up the variations for a new dessert every time.

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.

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.

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.
