Peanut Butter & Fluff Cookies

A twist on a classic New England sandwich!

Yield: 12 cookies

You will need:

  • 3/4 cup flour
  • 1 & 1/4 cup light brown sugar
  • 1 cup creamy peanut butter
  • 8 tablespoons butter, room temperature
  • 1 egg
  • 1 teaspoon baking soda
  • 1 teaspoon vanilla extract
  • 1 pinch of salt
  • about 1/4 cup of fluff (depends on how much you put on each cookie)


  • In one bowl or stand mixer, combine all dry ingredients.
  • Add in peanut butter and brown sugar, beat until well combined.
  • Add in egg and vanilla, beat until well combined. Scrape down the sides of the bowl to make sure all ingredients are well mixed and there are no chunks.
  • Cover the dough with plastic wrap and chill in the refrigerator for at least one hour. This prevents the cookies from spreading out too thin when they are baking.
  • When nearly done chilling, preheat oven to 375 degrees. Line a cookie sheet with parchment paper or non-stick spray.
  • Scoop out about 1 tablespoon of cookie dough onto the tray and place them about 2 inches apart.
  • Use the back of the cookie scoop or spoon to create a little dent in the center of the dough, and place about a teaspoon of fluff into the center. Put a little bit of cookie dough on top of the fluff.
  • Bake for 8-10 minutes. When done, the cookies will start to crinkle and stop spreading.
  • Let the cookies set and cool for 10 minutes, enjoy!
