Chocolate Peanut Butter Cookies with Peanuts and Marshmallows


I have emerged from the depths of the blogging world where I have been hiding for quite some time now… with a delectable cookie recipe! I don’t usually hang on to cookie recipes, as I always figure I can hunt down something even more delicious. Nope. This one is for keeps. The original recipe is from here; however, I didn’t have any pb m&ms handy, so I improvised (though I suspect the original recipe is also great). These are a fragile and perhaps not-too-pretty variety of cookie, but the taste makes up for it.

Facts that were reconfirmed while making these cookies:

  1. Peanut butter is a pain in the butt to clean.
  2. PB & Chocolate is such an unbeatable combo that point #1 is moot.

See below for the recipe and ingredients! Also… try not to eat these for breakfast AND lunch like I did. Not healthy. Not at all.

Ingredients (Yield ~ 2 dozen):

  • 1/2 cup butter
  • 1/2 cup creamy peanut butter
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 1 egg
  • 1 tsp vanilla
  • 2 tbsp milk
  • 1 3/4 cup all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 cup semi-sweet chocolate chips
  • 1/2 cup salted peanuts (halved)
  • 3/4 cup mini marshmallows


  1. Preheat the oven to 350 F and prepare a baking sheet.
  2. Cream butter in a large mixing bowl until smooth. Add in peanut butter, mixing until fully incorporated.
  3. Cream sugars with the butter mixture.
  4. Add in egg, vanilla, and milk. Mix until smooth.
  5. In a smaller mixing bowl, combine flour, baking soda, and salt. Gradually add this into the wet ingredients until well combined.
  6. Lastly, mix in chocolate chips, peanuts, and marshmallows.
  7. Spoon in heaping tablespoons on to the baking sheet- do not flatten out the dough. Bake for about 7-8 minutes and remove while still slightly undercooked. Leave on baking sheet to cool for 5 minutes. *Note:* my cookies puffed up in the oven, but flattened back out and hardened up while cooling.
  8. VERY carefully transfer to a cooling board and leave to cool completely. If you try to move the cookies too much before they are totally cool, they will fall apart. Enjoy!
