Ultimate Gooey S’mores Cookies – Easy Campfire-Style Dessert

If you love gooey marshmallows, melty chocolate, and buttery cookie dough, you’re in for a real treat. These s’mores cookies capture all the best parts of the campfire classic—without needing to strike a single match. They’re soft, chewy, and packed with mini marshmallows, graham cracker crunch, and chunks of Hershey’s chocolate.

This is one of my family’s favorite weekend bakes. My kids love smashing graham crackers, sneaking marshmallows, and fighting over who gets the first warm cookie off the tray. They’re easy enough for beginner bakers, yet impressive enough for summer parties or cozy movie nights.

Everything You Need to Make the Best S’mores Cookies

This recipe is simple and family-friendly. Here’s what to gather:

Ingredients:

• 1 1/2 cups all-purpose flour (180g)
• 1/2 tsp baking powder
• 1/2 tsp baking soda
• 1 tsp cornstarch
• 3/4 cup semisweet chocolate chips
• 10 tbsp unsalted butter, room temp
• 1/4 cup granulated sugar
• 1/2 cup light brown sugar
• 1 egg
• 1 tsp vanilla extract
• 1/4 tsp salt
• 1 cup mini marshmallows or marshmallow bits, divided
• 1 bar Hershey’s Chocolate (1.55oz), roughly chopped
• 4 graham crackers (56g), chopped

Ingredient Tips:

• Marshmallows: Halve the mini ones so they don’t explode or take over your cookies.
• Chocolate: Go classic with Hershey’s or swap for dark if you like less sweetness.
• Butter: Room temperature is key for a smooth dough.

How to Make S’mores Cookies – Step-by-Step

1. Prep Your Mix-Ins

2. Mix the Dry Ingredients

• In a medium bowl, whisk together:
• Flour
• Baking powder
• Baking soda
• Cornstarch
• Salt

3. Cream the Butter and Sugars

• In a mixing bowl, beat butter, brown sugar, and granulated sugar on medium speed until creamy (about 2 minutes).
• Add in egg and vanilla extract.
• Scrape the sides and mix briefly until fully combined.

4. Bring the Dough Together

• Gradually add dry ingredients to the wet.
• Mix on low speed until just combined—don’t overwork it.
• Add the chopped graham crackers, chocolate chips, and marshmallows (reserve a few for topping).
• Stir in gently.

5. Chill the Dough

• Cover the dough and refrigerate for at least 1 hour.

6. Bake the Cookies

• Preheat oven to 350°F (175°C).
• Scoop 2-tablespoon portions and roll into balls.
• Place on a parchment-lined baking sheet, 2 inches apart.
• Bake for 8 minutes.
• Quickly top with reserved marshmallows and Hershey’s chunks.
• Return to oven for 2–3 minutes until edges are golden.

7. Cool and Shape

• Let them cool completely on the pan.
