Oh, friends!

I think you will really like these reese’s bars.

Whoever came up with the idea of pouring sweetened condensed milk on top of brownies is a genius.

Yeah, you’re just adding more sweet on top of sweet, but it’s magical, hence the name reese’s MAGIC bars.

This is the perfect magic bar recipe for those of us who can’t get enough peanut butter and chocolate!

This husband of mine likes to turn anything into a joke. I told him don’t forget to take the reese’s magic bars to work tomorrow and he said, “what should I call them.. REESE’S magic bars or reese’s MAGIC bars, or reese’s magic BARS” – with an emphasis on a different word each time he said it.

I told him to just call them reese’s magic bars otherwise his co-workers might think I’m crazy! When he came home that evening, he told me that the bars disappeared and it must have been the way he emphasized the word magic.

At least he got the name right. Unlike the time he told his coworkers that these sugar cookie bars were called 80s sugar cake. LOL 🤦

There are TWO very important recipe notes!

First – please, please remember to line your 9×13 inch pan with foil!! I will admit that I forgot that step in the video, but lining the pan will make your job a whole lot easier when taking the bars out of the pan!

Second – it is crucial to use at least a 19oz box of brownie mix. I first tried it with a 18.3oz box of brownie mix and it turned out wonky. Ghirardelli makes 19oz boxes, and Betty Crocker makes some 19.1oz boxes. So read the boxes when you go grocery shopping, friends!

And lastly – want to use more then 6 reese’s cups? That’s a great idea!!

Reese’s brownies with sweetened condensed milk - an easy party dessert known as Reese’s Magic Bars!

Ingredients:

  • one box of 19 oz brownie mix (be sure to check the oz!)
  • 1 stick unsalted butter, softened (1/2 cup)
  • 1 egg
  • 1/4 cup vegetable oil
  • 6 Reese’s peanut butter cups, chopped (regular size, more if using mini’s)
  • 1/2 cup peanut butter chips
  • 14 oz can sweetened condensed milk (use about 3/4 of the can)

Directions:

**Do not follow the directions on the back of the brownie box**
  1. Preheat the oven to 350ºF and line a 9x13 inch pan with aluminum foil, spray lightly with non-stick cooking spray.
  2. In a large mixing bowl combine the butter, egg, vegetable oil and brownie mix. The mixture will be thick! Then evenly press the brownie mixture into the prepared 9x13 inch pan. Tip: spray your hands with non-stick cooking spray and then press the brownie mixture into the pan.
  3. Sprinkle the chopped reese’s peanut butter cups and the peanut butter chips evenly over the brownie.
  4. Evenly drizzle about 3/4 of the can of sweetened condensed milk over the brownie, stop when you can still see some of the brownie base.
  5. Bake for 28-30 minutes or until the center of the bars are set. Remove the pan from the oven and allow it to cool, then put the pan in the fridge to cool completely before cutting the bars.  For easy slicing, lift the aluminum foil out of the pan.
