Peanut Butter S’mores Sandwich Cookies Recipe
Ingredients
- For the Cookies:
- 1 ½ cups (250 g) creamy peanut butter
- ½ cup (113 g) unsalted butter, softened
- ½ cup (100 g) granulated sugar
- ½ cup (100 g) light brown sugar, packed
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1 ¼ cups (160 g) all-purpose flour
- ¾ teaspoon baking powder
- ¼ teaspoon kosher salt
For the Filling:
- 1 cup (96 g) marshmallow fluff
- ¼ cup (64.5 g) creamy peanut butter, warmed for drizzling
- ½ cup (84 g) milk chocolate chips
Instructions
- Prepare the Cookie Dough:
Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. In a large mixing bowl, cream together the creamy peanut butter and unsalted butter until smooth and fluffy. Add both the granulated sugar and light brown sugar, and mix until fully combined. Beat in the egg and vanilla extract until smooth. - Mix Dry Ingredients:
In a separate bowl, whisk together the all-purpose flour, baking powder, and kosher salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. The dough should be thick and slightly sticky. - Shape the Cookies:
Using a tablespoon or a cookie scoop, drop rounded portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. Use your fingers or the back of a spoon to slightly flatten each dough ball, as they won’t spread too much during baking. - Bake the Cookies:
Bake the cookies for 10-12 minutes, or until the edges are lightly golden. Allow the cookies to cool on the baking sheet for about 5 minutes, then transfer them to a wire rack to cool completely. - Make the Filling:
While the cookies are cooling, prepare the filling. In a small bowl, gently warm the peanut butter in the microwave for 10-15 seconds until it becomes pourable. In another bowl, combine the marshmallow fluff with the warmed peanut butter and stir until smooth and creamy. - Assemble the Sandwiches:
Once the cookies have cooled, take one cookie and spread a generous spoonful of marshmallow peanut butter filling on the flat side. Sprinkle a few milk chocolate chips on top, then gently press another cookie onto the filling to form a sandwich. Repeat with the remaining cookies and filling. - Drizzle with Peanut Butter:
Once all the sandwich cookies are assembled, drizzle the warmed peanut butter over the top of each sandwich, and optionally, sprinkle with more chocolate chips for added decadence. - Serve and Enjoy:
Allow the cookies to sit for a few minutes to let the filling set slightly before serving. Enjoy these Peanut Butter S’mores Sandwich Cookies with a cold glass of milk, or store them in an airtight container for up to a week.
Health Benefits
While these cookies are a sweet indulgence, they do offer some nutritional benefits. Peanut butter is a great source of healthy fats, protein, and essential vitamins like vitamin E. Marshmallow fluff provides a sugar boost for quick energy, while the chocolate chips add antioxidants. However, due to the sugar and fat content, these cookies should be enjoyed as an occasional treat in moderation.
