Tips for perfect Flourless Peanut Butter Cookies:

  • First, try to use creamy peanut butter as works best in this recipe.
  • Similarly, I would say regular, store bought peanut butter is best. The homemade peanut butter may be too thick and you may have to add an extra egg yolk.
  • Ingredients should be at room temperature.
  • In addition, you can skip the mix ins and just have a regular peanut butter cookie.
  • I did that making these thicker helps them holding they shape better.
  • Let the cookies cool on the baking tray, when you remove them from the oven they are very soft, they will harden once they cool.
  • The mix ins are up to you, you can choose from chocolate chips, chopped peanuts, Reese’s pieces, M&M’s and any other things that come to your mind.

Can you freeze the Peanut Butter Cookies?

Yes. Wrap cookies tightly with aluminum foil or plastic freezer wrap, or place in heavy-duty freezer bag. Properly stored, it will maintain best quality for about 2 to 3 months.

Tools/Ingredients I used to make these Flourless Peanut Butter Cookies:

  • Peanut Butter – creamy and delicious, I always have some on hand
  • Cookie Pan – I have these and I like that they come in 3 sizes
  • Cooling Rack – perfect to cool and baked goods, transfer the cookies to the rack 10 minutes after baking, so they don’t continue to bake from the residual heat coming from the pan
  • Peanut Butter M&M’s – omg delicious!
  • Mini Reese’s Cups – creamy and peanut buttery, these make for a great mix in
  • Dark Chocolate Melts/Wafers – I love using these for the chocolate mixture as they are so easy to melt

Flourless Peanut Butter Cookies

Flourless Peanut Butter Cookies are soft, dense, thick, and are loaded with Reese's cups, peanut butter M&M's and dipped in chocolate. 


  • 2 cups creamy peanut butter
  • 2 cups sugar
  • 1 tablespoon pure vanilla extract
  • 2 large eggs
  • 1 tablespoon salt
Optional Mix ins
  • ½ cup mini Reese's cups
  • ½ cup peanut butter M&M's
Chocolate Coating:
  • 8 ounces semi-sweet chocolate chopped
  • 1 tablespoon light corn syrup
  • 2 tablespoons sprinkles


  1. Preheat oven to 350 degrees F.
  2. Cover two cookie sheets with non stick parchment paper. Set aside.
  3. In a medium bowl, lightly beat the eggs, add sugar and whisk until light and fluffy.
  4. Stir in peanut butter, vanilla and salt until well combined.
  5. Using a spatula stir in the mini Reese's cups and peanut butter M&M's.
  6. Using an ice cream scoop, or a regular spoon, scoop the mixture and form balls. Place them about 2 inches apart onto the baking sheets. Flatten the tops with the tines of a fork. The cookies should be about ¼ inch thick.
  7. Bake until golden around the edges, about 12-14 minutes, switching the position of the sheets halfway through baking.
  8. Cool on the baking sheets for 10 minutes, transfer cookies to a cooling rack to cool completely.
  9. When the cookies have cooled melt the chocolate. Bring about an inch of water to a simmer in a saucepan. Set a heatproof bowl in the mouth of the pot, making sure the water doesn't touch the bottom of the bowl. Add the chocolate, let it soften for 1 min and stir until fully melted. Stir in corn syrup.
  10. When chocolate is melted, remove bowl from heat, dip in the cookies half way, place on a baking sheet covered with parchment paper and decorate with sprinkles or chopped peanuts immediately.
  11. Wait for chocolate to harden before serving.
  12. Enjoy!
