These Peanut Butter Cup Brownies In A Jar are easy individual servings of dessert for a party! They can be given as gifts or sold at a bake sale!

I made these little beauties for my party on Monday and they were delicious! Over the top?? Sure, but delicious anyway! And besides being adorable, they were easy to make! They consist of brownies, chocolate frosting, peanut butter cups, and peanut butter frosting.

**Update: I recently learned that Ball canning jars are NOT oven safe so I’ve changed the directions for this blog post.**

Bake the brownies according to the directions on the package. Use a small cookie cutter or the top of the mason jar to cut circles of cooked brownies out of the 9×13 pan. Place the brownie circles in the mason jars.

Pipe on store-bought chocolate frosting on top of the brownies. Or make your own if you have the time.

I cut a bunch of Reese’s Peanut Butter Cups into small chunks… sorry I didn’t count how many, but I think you need a little more than 1 peanut butter cup per jar.
