Peanut Butter Cookie Dough

Two of my favorite treats are brownies and cookie dough. So I figured… why not put them together? I brought them to a friends house and I told him he could take a few before we left and he took half the pan – they were THAT good! Ha Ha!

Recipe type: Dessert
Cuisine: American
Prep time: 
Cook time: 
Total time: 
Serves: 20
  • Brownie Mix for a 9x13 pan
  • ¼ cup salted butter, softened
  • ½ cup peanut butter + 6 Tablespoons of peanut butter (JIF is my favorite!)
  • ½ cup granulated sugar
  • 1 cup brown sugar
  • ¼ cup + 2 tablespoons milk
  • 1 tablespoon vanilla extract
  • 2 cups all purpose flour
  • 2 cups of Peanut Butter M&M's
  1. Cook your brownies as the directions on the box suggest.
  2. Once they are out of the oven, take 3 Tablespoons of peanut butter and gently spread it over your warm brownies. Let them sit and cool.
  3. With an electric mixer, cream the butter and peanut butter until smooth.
  4. Add the sugar, brown sugar, milk and vanilla, and mix until smooth. Carefully add the flour, and continue to mix at low speed until fully combined.
  5. Spoon the cookie dough onto the cooled brownies and spread gently into an even layer.
  6. Sprinkle on all of the M & M's so they are spread out across all of your brownies.
  7. Melt the last 3 Tablespoons of peanut butter in the microwave (about 30 seconds) and drizzle over your brownies.
  8. Slice into squares. (These are very rich so you might want to cut them into small squares)
  9. Cover and stick in your refrigerator until you are ready to eat them!

      You could easily make these into sugar cookie brownies. Omit all peanut butter and just put the dough right on top of the brownie. Add whatever topping you want and there you go! Hopefully this helps!!! Let us know how it goes!

    Thank you so much for this recipe. I took these to a meeting I had at church on Sunday afternoon and they were gone in seconds. A friend even emailed me during the meeting to get the recipe. Thank you for sharing.

      We like to keep any leftovers (and that’s not very often) in an airtight container in the fridge. They should be fine for about 3 to 4 days.

    These are delicious!! My mother-in-law made them for our dessert after Sunday dinner last week, and I basically inhaled my piece and then ate a second piece right after :) I took home some leftovers on Sunday, and I just barely ate another piece, on Thursday, so it’s been several days but it still tastes awesome and isn’t dry at all. I’m sure at some point I will make these myself, but for now I’m just grateful my Mother-in-law introduced me to them!! :)
