  • 1/2 cup unsalted butter
  • 1/4 cup granulated sugar
  • 1/4 cup brown sugar packed
  • 1/2 cup peanut butter
  • 1 large egg
  • 1/2 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup all purpose flour
  • 1 cup semi-sweet chocolate chips
  • Mini marshmallows optional


  • Preheat oven to 375 degrees F.
  • Cube butter into tablespoon sized pieces.
  • Place a skillet over medium-low heat and whisk in butter cubes.
  • Whisk continuously for about three and a half - five minutes, or until the butter starts to smell like caramel and there are brown bits forming in the bottom of the pan.
  • Remove from heat and continue to whisk for thirty more seconds.
  • Remove from pan into a bowl and aside to cool.
  • Once the butter has cooled (does not need to re-solidify, just cool down), cream browned butter and both sugars until smooth.
  • Add in peanut butter, egg, and vanilla and mix until the egg is well incorporated.
  • You may need to stop and scrap down the bowl a few times.
  • Slowly add the baking soda, salt, and flour until combined.
  • Lastly, add in chocolate chips and mix well.
  • Using a cookie scoop (1.5 T), scoop cookie dough onto a prepared baking sheet (greased or lined with a silpat mat).
  • Gently press down on the dough to flatten and place 8 mini marshmallows on top of the cookie dough. Top with another scoop of cookie dough and gently squish together until it forms one cookie. *See the notes below for more detailed instructions on how I stuffed the cookies.
  • Bake for 8-15 minutes or until the bottom is lightly golden (baking time varies depending on if you're stuffing the cookies or not).
  • Remove from oven and let set for 5-10 minutes.
  • Remove from the baking sheet and transfer the cookies onto a cooling rack.
  • Take 5 seconds to rate this recipe below. We greatly appreciate it!


Baking time: If you're not stuffing the cookies, I found that about 8-10 minutes was perfect for cooking them through. If you are stuffing the cookies, I'd give them about 12 - 15 minutes.
If you're using mini marshmallows, I found that squishing them together to form one large marshmallow clump helps to keep them inside the cookie dough.
The best way to stuff the cookie dough with marshmallow: Cup one cookie dough ball and form it so its shaped like the palm of your hand or like a little bowl. Stuff in marshmallows and top with another bowl shaped cookie dough ball. Pinch together the seam and gently swish until it forms one big chunk of cookie dough! It just takes a little practice!
