Soft-baked, thick style peanut butter cookies topped with melty marshmallow and chocolate. Bring campfire s’mores inside!


  • 1 batch peanut butter cookie dough
  • 12 large marshmallows, cut in half (shown above)
  • 8 oz melting chocolate (such as Bakers brand)
  • optional: sprinkles


  1. Prepare peanut butter cookies dough through step 3.
  2. Preheat oven to 350°F (177°C). Line large baking sheets with parchment paper or silicone baking mats. Roll chilled cookie dough into balls, about 1.5 Tablespoons of dough each. Arrange 3 inches apart on prepared baking sheets. Bake for exactly 10 minutes. Remove from oven and place marshmallow on top, gently pressing it down into the warm cookie. Place back into the oven for 2-3 more minutes so the marshmallow can melt and the cookie can finish baking.
  3. Remove from oven and allow to cool for about 5 minutes. As the cookies cool, melt chocolate according to package directions. Spoon about teaspoons of chocolate on top of each marshmallow and swirl around with the back of the teaspoon. Top with sprinkles if desired.
  4. Cookies remain fresh covered at room temperature for up to 7 days in an airtight container.
