These Peanut Butter S’mores Sandwich Cookies combine rich, nutty peanut butter cookies with gooey marshmallow and sweet chocolate for the ultimate cozy dessert. Each bite delivers a delicious contrast of chewy cookie, creamy filling, and classic s’mores flavor. They’re an irresistible treat for parties, family baking days, summer gatherings, or whenever you’re craving a nostalgic dessert.
Can This Peanut Butter S’mores Sandwich Cookies Support Weight Loss Goals?
These cookies are best enjoyed as an occasional dessert rather than a weight-loss-focused food. Peanut butter provides some protein and fat, which can make the cookies more satisfying than a plain sugar-based cookie, but the recipe also contains added sugar, chocolate, and marshmallow. Enjoying one portion mindfully can allow you to include this treat within an overall balanced eating pattern.
Does Peanut Butter S’mores Sandwich Cookies Fit a High-Protein Lifestyle?
These cookies can fit into a high-protein lifestyle as an occasional sweet treat, although they are not a high-protein recipe. Peanut butter contributes some protein, while flour, chocolate, and marshmallow provide most of the remaining calories from carbohydrates and fats. The net-carb content is relatively high compared with a protein-focused snack. For a more protein-friendly serving, pair one cookie sandwich with Greek yogurt or another protein-rich food.

My Personal Experience
- The peanut butter aroma was the first thing I noticed.
The cookies smelled wonderfully rich while baking, with a warm roasted-peanut fragrance filling the kitchen. - The texture made these cookies stand out.
The edges became lightly crisp while the centers stayed soft and chewy, creating a perfect base for the filling. - The marshmallow center made every bite more fun.
The sweet, sticky filling paired beautifully with the salty peanut butter flavor. - Chocolate made the sandwich taste like a real s’more.
A little melted chocolate between the cookies added just enough richness without overpowering the peanut butter. - They were especially good slightly warm.
Reheating them briefly softened the chocolate and marshmallow for that fresh-from-the-oven experience.

Common Mistakes to Avoid
- Overbaking the cookies — Peanut butter cookies can become dry quickly, so remove them when the edges are set but the centers still look slightly soft.
- Using too much marshmallow filling — An overly thick layer can squeeze out when the cookies are pressed together.
- Assembling while the cookies are too hot — Allow the cookies to cool slightly so the filling doesn’t melt excessively.
- Skipping the chilling step — Chilling the dough helps prevent the cookies from spreading too much during baking.
Required Equipment
- Mixing bowls — Keeps the wet and dry ingredients organized for even mixing.
- Electric mixer — Creams the butter, peanut butter, and sugar smoothly.
- Cookie scoop — Creates evenly sized cookies that bake at the same rate.
- Baking sheets — Provide a flat surface for consistent baking.
- Parchment paper — Prevents sticking and makes cleanup easier.
- Wire cooling rack — Helps cookies cool evenly without becoming soggy underneath.
- Microwave-safe bowl — Makes melting the chocolate quick and convenient.
Storage Instructions
Store assembled cookies in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days. Place parchment paper between layers to prevent the marshmallow filling from sticking.
For longer storage, freeze the baked cookies without the marshmallow filling in a freezer-safe airtight container for up to 2 months. Thaw at room temperature, prepare fresh filling, and assemble before serving. If already assembled, they can also be frozen, although the marshmallow texture may become slightly softer after thawing.

📝 Ingredients
Peanut Butter Cookies
- 1½ cups (188 g) all-purpose flour
- ½ teaspoon baking soda
- ¼ teaspoon baking powder
- ½ teaspoon salt
- ½ cup (113 g) unsalted butter, softened
- ¾ cup (150 g) creamy peanut butter
- ½ cup (100 g) granulated sugar
- ½ cup (100 g) packed light brown sugar
- 1 large egg
- 1 teaspoon vanilla extract
S’mores Filling
- ½ cup (90 g) semi-sweet chocolate chips
- 12 large marshmallows
- 2 tablespoons (30 g) creamy peanut butter, optional
Ingredient notes: Use regular creamy peanut butter rather than very oily natural peanut butter for a more consistent cookie texture. For a stronger s’mores flavor, use milk chocolate. For a less-sweet version, choose semi-sweet or dark chocolate.
Directions
- Prepare the dry ingredients.
Whisk together flour, baking soda, baking powder, and salt in a medium bowl. Set aside. - Cream the butter and peanut butter.
Using an electric mixer on medium speed, beat the softened butter and peanut butter for about 1–2 minutes, until smooth and creamy. - Add the sugars.
Beat in the granulated sugar and brown sugar for another 2 minutes, until the mixture looks fluffy. - Add the egg and vanilla.
Mix on low to medium speed until the egg and vanilla are fully incorporated and the mixture looks smooth. - Combine the dough.
Gradually add the dry ingredients and mix on low speed just until no obvious streaks of flour remain. Avoid overmixing, which can make the cookies tougher. - Chill the dough.
Cover the bowl and refrigerate for 30 minutes. The dough should become firm enough to scoop easily. - Preheat the oven.
Heat the oven to 350°F (175°C). Line baking sheets with parchment paper. - Shape the cookies.
Scoop approximately 2 tablespoons of dough per cookie and roll gently into balls. Place them about 2 inches apart on the prepared baking sheets. Lightly flatten each ball with your palm. - Bake.
Bake at 350°F (175°C) for 10–12 minutes. The edges should look set and lightly golden while the centers remain slightly soft. - Cool.
Let the cookies rest on the baking sheet for 5 minutes, then transfer them to a wire rack. Allow them to cool completely before assembling. - Prepare the chocolate.
Place chocolate chips in a microwave-safe bowl. Microwave at 50% power in 20-second intervals, stirring between each interval, until smooth. - Add the marshmallow.
Place one marshmallow on the flat side of half the cookies. Warm it in a microwave for approximately 5–8 seconds, just until it begins to puff. Watch carefully because marshmallows expand quickly. - Build the sandwiches.
Spread a small amount of melted chocolate over the marshmallow. Add a second cookie and gently press until the marshmallow spreads toward the edges. - Let the filling set.
Allow the assembled cookies to rest for 5–10 minutes. The chocolate should become slightly firmer while the marshmallow remains soft and gooey. - Serve.
Enjoy immediately for the softest marshmallow texture, or store according to the storage instructions.
High-protein cooking tip: While this recipe isn’t inherently high in protein, pairing one sandwich cookie with plain Greek yogurt or a protein-rich milk can make the overall snack more protein-balanced.

Frequently Asked Questions
Can I use crunchy peanut butter?
Yes, crunchy peanut butter works well and adds small pieces of peanuts for extra texture.
Can I make these cookies ahead of time?
Yes, bake the cookies ahead and assemble them with the marshmallow and chocolate shortly before serving for the best texture.
Can I use dark chocolate?
Absolutely; dark chocolate gives the cookies a deeper flavor and balances the sweetness of the marshmallow.
Why did my cookies spread too much?
The dough may have been too warm, so chilling it for the recommended 30 minutes helps the cookies hold their shape.
Can I freeze Peanut Butter S’mores Sandwich Cookies?
Yes, but freezing the unfilled cookies is preferable because marshmallow filling can change texture after freezing and thawing.
Are these cookies high in protein?
They contain some protein from peanut butter and flour, but they are better described as a protein-containing dessert rather than a genuinely high-protein recipe.
