Flourless Peanut Butter S'mores Cookies

Flourless Peanut Butter S'mores Cookies || To Salt & See

It has been a busy last couple weeks, filled with traveling, the holidays, hosting, and working. We were so fortunate to have our friends Josh and Cate come to visit us for New Years. They live in the Bay in California – and when California friends voluntarily come to the artic tundra that is Minnesota during the winter to visit you and your husband, then you know they must really love you lol. Unfortunately was unusually colder than normal while they were here – staying below zero degrees Fahrenheit for the majority of the time, with the “feels like” temperatures ranging between -30F to -15. But they were troopers, and were still willing to go outside, despite the thick ice that had accumulated on the inside of our windows to possibly deter them.

We laughed our faces off while playing What Do You Meme, and tired our brains out while playing Code Names. We went to the Target Center to watch the Timberwolves beat the Lakers. We learned along with the little kiddos at the Science Museum. We spent our New Years making predictions for the coming year, playing Taboo for hours, and having a quick glass of champagne at midnight. It wasn’t full of sequence dresses, fireworks, or the trendy glitter decorations that you see on Instagram. Rather it was laid back and spent with loved ones and perfect.

One of the days while they were here we did some sledding and built a snowman in the morning. Then in the afternoon the boys went cross country skiing while the girls stayed at home, did some Cate-friendly baking (aka gluten free/dairy free), and watched Harry Potter. We made these peanut butter s’mores cookies and OMG you guys, they are SO good! The cookies are a variation of the 3 ingredient (PB, sugar, and egg) peanut butter cookies that my mom used to make. These flourless cookies have a peanut butter base, which makes them SUPER peanut buttery, which is great for the peanut butter lovers out there such as myself. In the recipe you will place the marshmallow on the cookie 2/3rds of the way through baking. I found that placing the marshmallow on at start was too much baking time for the mallows and they would slid off. Not ideal. The cookies are easy to make, only require one bowl, and fricken delicious. 

Flourless Peanut Butter S'mores Cookies

Prep time:

Bake time:

Serves: 10


  • 1 cup natural peanut butter, smooth
  • 1 cup granulated sugar
  • 1 egg
  • 1/2 salt (omit if peanut butter is salted)
  • 1/2 cup mini marshmallows
  • 1/3 cup peanuts
  • 1 cup semi-sweet chocolate


  1. Preheat oven to 325F. Line a baking sheet with parchment paper or a silicon mat, set aside.
  2. In a large mixing bowl, stir the peanut butter, sugar, egg, and salt (omit salt if peanut butter is salted) together until well combined.
  3. Fold in the marshmallows.
  4. Roll dough into tablespoon sized balls. Place on the prelined baking sheet, spacing an inch apart. Slightly flatten the cookies.
  5. Bake for 15 minutes.
  6. Transfer cookies to a cooling rack to cool completely.
  7. Finely chop the peanuts. Place in a bowl.
  8. Melt the chocolate in a double boiler (*). Dip half of a cookie in the melted chocolate, then roll in the peanuts. Return to the cooling rack to allow the chocolate to solidify. Repeat with the remaining cookies.

(*) Baker’s Notes:
How to make a double boiler: Fill a pot with 1 1/2-inches of water. Bring to a simmer - do not boil. Place a bowl into the pot - the bottom of the bowl should be a couple inches above the water. NO PART of the water should touch any part of the bowl. Place the chocolate in the bowl, and stir occasionally as it melts. Be careful to not get any water into the bowl, as this will cause the chocolate to seize. For best results, occasionally lift the bowl out of the pot, wipe away the condensation under the bowl, then return to the pot. Once the chocolate is melted, remove the bowl from the pot, and again, wipe away any condensation.
