Peanut Butter Cup Surprise Monster Cookies Recipe

At first glance, these might look like ordinary oatmeal M&M cookies, but the secret surprise inside makes this dessert a game changer. Peanut butter cup surprise monster cookies are soft and chewy M&M-speckled oatmeal cookies filled with a creamy peanut butter cup.

Peanut butter + oats + M&Ms = monster cookies! But this peanut butter cookie dough is a little different from our original monster cookies. They’re a little closer to these peanut butter cup oatmeal cookies. The difference? For this recipe, we use all brown sugar to keep the cookies extra soft and flavorful.

Tell Me About these Peanut Butter Cup Surprise Monster Cookies

  • Flavor: Peanut butter is front and center. You’ll love all the peanut butter flavor paired with chocolate from both the peanut butter cup and M&Ms.
  • Texture: Thanks to the brown sugar, these cookies stay thick, soft, and extra chewy. Quick oats are responsible for the uniform texture. Make sure to use quick oats, NOT old-fashioned oats. Quick oats are smaller than old-fashioned oats and more finely ground. Tip: If you only have old-fashioned oats, just pulse them in your food processor a few times so they’re smaller. While regular M&M’s certainly work, we prefer the mini ones because you get more M&Ms in each monster bite.
  • Ease: Start by making the easiest peanut butter cookie dough. Guess what? There’s no mixer required. And it gets better: there’s no dough chilling required either. The quicker you begin, the quicker you’ll be eating these peanut butter cup monster cookies.
  • Time: No dough chilling makes this recipe one of the quickest and easiest cookies on our website. If you want cookies in a hurry, here are a few more time-saving cookie recipes that don’t require chilling. Snickerdoodles and shortbread cookies are two favorites!

Description

Peanut butter monster cookies with a Reese's peanut butter cup inside!!

Ingredients You’ll Need
  • 3/4 cup (94g)
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1/2 cup (8 Tbsp; 113g)
  • 1 cup (200g)
  • 1 large egg, at room temperature
  • 1/2 cup (125g)
  • 2 teaspoons pure vanilla extract
  • 2 cups (170g)
  • 1 and 1 1/4 cups mini or regular size M&Ms
  • 18 Reese’s 18 miniature peanut butter cups, unwrapped
Instructions
  1. 1
    Preheat oven to 350°F (177°C). Line 2 large baking sheets with parchment paper or silicone baking mats. (Always recommended for cookies.) Set aside.
  2. 2
    Toss the flour, salt, and baking soda together in a large bowl. Set aside.
  3. 3
    In a medium bowl, whisk the melted butter and brown sugar together until no brown sugar lumps remain. Whisk in the egg, then the peanut butter until combined. Finally, whisk in the vanilla. Pour the wet ingredients into the dry ingredients and mix together with a large spoon or silicone spatula. The dough will be very soft and slick. Fold in the oats and the M&Ms. Allow the cookie dough to sit for 15 minutes—the oats will absorb some moisture, making the dough easier to work with.
  4. 4
    . Take 1 Tablespoon of dough and slightly flatten out on the prepared baking sheet. Stick a peanut butter cup on top, as shown above. Top the peanut butter cup with 1.5 Tablespoons of cookie dough and seal down the sides so that the peanut butter cup is securely stuffed inside. You can pick it up and roll into a smooth ball if needed. Slightly flatten down the top as best you can (it can’t be totally flat because of the peanut butter cup inside). Repeat with the rest of the dough and peanut butter cups.
  5. 5
    Bake the cookies for 12-13 minutes. The cookies will look very soft. They will continue to bake on the cookie sheet. Remove from the oven and lightly press down on each cookie to slightly flatten (if they didn’t spread much in the oven). Allow to cool on the cookie sheet for 10 minutes before transferring to a wire rack to cool completely.
