How Do You Make Peanut Butter Cookie Dough Brownies?

I use my Brownie Recipe, which happens to be the best ever…try it if you haven’t already…BUT I added peanut butter cookie dough (egg-free of course) on top in a nice thick layer, because chocolate and peanut butter together is pure love.

Feel free to use any brownie recipe you would like, you can even use a boxed mix if you’re in a pinch! The fun part comes when you add the peanut butter cookie dough all over the top!

AND when you add the spider garnish, they become festive and spooky, PERFECT for your Halloween party!

  3. Spread the cookie dough all over the brownies.

Peanut Butter Cookie Dough BrowniesHow To make Peanut Butter Cup Spiders

  1. Use 2 different sizes of peanut butter cups, the miniature and itty bitty ones.
  2. On the smallest ones I piped on eyes with black frosting.  You could also use the black gel, or even black candy melts.
  3. I placed them on the brownies, you can do it when they are cut or still in the pan.
  4. I used Chocolate Twizzlers for the legs…I just cut them skinny… you could also use pretzels or black licorice.
