Ingredient to make peanut butter s'mores cookies set out on the counter.
  • All-Purpose Flour—To ensure the cookies are light and fluffy!
  • White Granulated Sugar—Sweetens your cookie base and gives a nice chewy texture.
  • Light Brown Sugar—Adds depth of flavor and extra moisture to your cookies.
  • Salted Butter—Softened. This will make your dough rich and soft.
  • Eggs—Gives your finished s’mores cookies a nice structure.
  • Reese’s Peanut Butter Cups—Are pressed into the top of each cookie to add some extra sweetness and peanut butter flavor.
  • Marshmallow Fluff—Because you can’t have a s’more without marshmallows!
  • Graham Crackers—Crushed. To add a little crunch!
  • Semi-Sweet Chocolate Chips—The slight bitterness of the chocolate helps to balance all the other sweet and salty flavors.
  • Vanilla Extract—Just a splash will add a rich homemade flavor to these cookies.
  • Baking Soda and Baking Powder—By using both, your finished cookies will rise nicely and spread evenly.

How to Make Peanut Butter Cup S’mores Cookies

Sugar, brown sugar and butter in a mixing bowl.
Eggs and vanilla added to the butter sugar mixture in the mixing bowl.

The first step is to cream the butter and sugars together in a large bowl with an electric hand mixer. Then add the eggs and vanilla and whisk until smooth.

Graham crackers, flour, baking powder and baking soda added to the batter in the mixing bowl.
Chocolate chips are added to cookie batter in the mixing bowl.

Next you will need to reduce your mixer to a lower speed and mix in the graham crackers, flour, baking powder, and baking soda until the dry and wet ingredients are combined.

Last step is to fold in the chocolate chips until evenly mixed throughout the dough.

Cookie dough and marshmallow fluff rolled into balls and placed on a cookie sheet.
Reese's cup pressed into the top of each baked cookie on the baking sheet.

Scoop the dough into medium-sized balls. Add a teaspoon of marshmallow fluff to each ball of dough and use your hands to roll the two together.

Place the balls of cookie dough on a baking sheet and bake until the edges begin to crisp. Then Remove from the oven and press a Reese’s cup into the top of each cookie.

Serve with a tall glass of milk or hot chocolate, and enjoy!

How To Prevent Dry Cookies

There are two reasons your cookies might seem a little bit dry. The first reason is that there is too much flour. To avoid this, make sure you whisk or mix your flour with a fork before you start measuring because flour tends to settle and compact as it sits.

The second reason the cookies are dry could be due to overbaking them. Be sure to check the cookies often and take them out once you start to see a golden brown color forming around the edges. If you leave them in the oven too long, these cookies will dry out and lose their soft and chewy texture.

Storing Cookies

These cookies are best stored in the fridge since the peanut butter cup and marshmallow fluff will get soft and sticky if they are left at room temperature on the counter.

You can store your cookies in a Ziploc bag or airtight container in the refrigerator for up to 4 days. Enjoy the leftover cookies cold or reheat them in the microwave for 15-20 seconds until warm!

Recipe Tips

  • The crushed graham crackers help give these cookies the classic s’mores flavor we all know and love! You can also use chocolate graham crackers instead for a more rich cookie.
  • Use a cookie scoop or spoon to scoop the dough and form it into medium-sized balls, you want them about 2 tablespoons in size.
  • A little bit of marshmallow fluff goes a long way. Since it expands so much as it heats up you only need about 1/2 - 1 teaspoon per cookie. Any more than that and your cookies will start to expand too much.
  • I like to use the back of a spatula or bottom of a glass to press Reese's into the cookies. This will keep you from leaving fingerprints on the melty chocolate.
  • The peanut butter cups will melt pretty fast, giving you a gooey s’mores experience! We like to chill the cookies in the fridge for 30 minutes prior to serving to make them less messy to eat.
  • To contrast the sweet taste of the cookies, you can top them with a light sprinkle of sea salt once they come out of the oven!
