How to Make Peanut Butter S’more Cookies

Preheat your oven to 350º F and line 2 cookie sheets with parchment paper.

Over the bowl of a stand mixer fitted with the paddle attachment, cream the butter and sugars on medium-high speed for 2-3 minutes, until light and fluffy.

Add the egg and beat on low speed until combined. Incorporate the peanut butter and vanilla extract, continuing to mix for another minute.

In a medium bowl, whisk together the flour, baking soda, and salt. Gradually mix the dry ingredients into the wet mixture until just combined. Avoid over-beating.

Fold in 1 cup of chocolate chips gently with a wooden spoon.

Using a 1 1/2 teaspoon cookie scoop, form cookie dough balls and slightly flatten the top of each cookie. Place them 2 inches apart on prepared baking sheets and press 3 mini marshmallows on top of each cookie. 

Bake cookies for 8-10 minutes until the edges are golden brown. Allow cookies to cool on the cookie sheet for 1 minute, then transfer to a wire rack to cool completely.

Melt the remaining chocolate and place it in a ziplock bag or piping bag. Cut a tiny corner and drizzle melted chocolate over each cookie. Let cool completely before enjoying your delicious s’mores cookies.

Expert Tips
