To make these Peanut Butter S’mores Cookies, gather the following ingredients:
For the Cookie Dough:
- 1 cup creamy peanut butter
- ½ cup unsalted butter, softened
- 1 cup brown sugar
- ½ cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 ½ cups all-purpose flour

How to Make Peanut Butter S’mores Cookies Stuffed with White Chocolate Reese’s
Step 1: Preheat & Prep
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. This keeps the cookies from sticking and makes cleanup easier.
Step 2: Make the Peanut Butter Cookie Dough
- In a large mixing bowl, cream together the peanut butter, softened butter, brown sugar, and granulated sugar until smooth.
- Add the egg and vanilla extract, then mix until fully combined.
- In a separate bowl, whisk together the flour, baking soda, baking powder, salt, and crushed graham crackers.
- Gradually mix the dry ingredients into the wet ingredients, stirring until a soft dough forms.
Step 3: Assemble the Cookies
- Place a graham cracker piece on the prepared baking sheet.
- Place a White Chocolate Reese’s Peanut Butter Cup on top of each graham cracker.
- Add a few mini marshmallows on top of the Reese’s cup.
- Take a heaping spoonful of cookie dough and gently press it over the marshmallow and Reese’s, sealing the edges.
Step 4: Bake to Perfection
Bake the cookies for 12-14 minutes, or until the edges turn golden brown. The center will still look soft, but that’s perfect—these cookies will firm up as they cool.
Step 5: Cool & Enjoy
Let the cookies cool on the baking sheet for about 5 minutes, then transfer them to a wire rack. Enjoy warm for the ultimate gooey, s’mores-like experience!
Tips for the Best Peanut Butter S’mores Cookies

✅ Use Creamy Peanut Butter – For the best texture, avoid natural peanut butter, as it can be too oily.
✅ Chill the Dough (Optional) – If your dough is too sticky, chill it in the fridge for 30 minutes before assembling the cookies.
✅ Don’t Overbake – These cookies will continue to cook as they cool, so take them out when the edges are just golden brown.
