Peanut Butter Cookie Pizza Crust

To make the peanut butter cookie crust, preheat the oven to 350°F and line a 12-inch round pizza pan with parchment paper. In a medium bowl, stir the peanut butter and sugars together until smooth. Both crunchy and creamy peanut butter would work. Beat in the egg. Then, stir in the baking soda, vanilla, and salt.

To roll out the crust, place the cookie dough on the parchment paper that is lining the pizza pan. Put another piece of parchment paper over the dough and with a rolling pin, roll out the dough to fit the pan. Remove the top piece of parchment paper and bake the cookie crust for 8-10 minutes, or until the center does not look wet. While the crust is baking, prepare the peanut butter sauce.

How to Make the Peanut Butter Sauce

To make the Peanut Butter Sauce, melt the butter and peanut butter over medium-low heat in a medium saucepan. Once they are fully melted and combined, add in the butterscotch chips. Remove from heat and stir continually until mostly melted. There will be chunks at the bottom of the pan, but that is not a problem. Set the sauce aside to cool a bit as you add the marshmallows to the crust.

Assembling the Peanut Butter Cookie Pizza

Once you have the peanut butter sauce made, the cookie crust should be finishing up baking for the first 8-10 minutes. Remove the crust and immediately add the miniature marshmallows to it. Turn the oven to broil and place the crust and marshmallows back into the oven for about a minute, or until the marshmallows just start to brown. Remove from the oven and top with the peanut butter sauce. Serve warm or at room temperature. Enjoy!

  1. I LOL’ed soo hard that I spilled my breakfast. “MEN” I thought I was the only one suffering such nightmares from them!!! I felt you were describing my husband :-)) But LOVE this recipe and can’t wait to try it out!!!

  2. Oh my…this is divine! There’s something about peanut butter and butterscotch…yummy. I don’t have a pizza pan so I made it rectangle. No parchment so o sprayed foil with nonstick spray, no marshmallows so used marshmallow cream. And I didn’t read the recipe through and didn’t toast the marshmallow. Despite all of this it was still the bomb! Thanks for sharing this exile.

  3. Seriously. This pizza is the BOMB! I can’t even explain the goodness. And so super easy! It’s requested often at my house.

    1. I am SO glad you like it!!! It’s seriously one of my favorite recipes on the blog but I have the hardest time convincing people how good it is! lol

  4. I am seriously thinking a handful of M&M’s or Chocolate Chips might be really great on top of this!
