Peanut Butter Sandwich Cookies

Peanut Butter Sandwich Cookies (Adapted from MS Baking Handbook)

For the cookie dough

2 cups all-purpose flour
1/2 teaspoon baking soda
1/4 teaspoon salt
12 tablespoons unsalted butter, softened
3/4 cup smooth peanut butter
1/2 cup granulated sugar
1/2 cup packed brown sugar
1 large egg
1 teaspoon vanilla

For the filling

3/4 cup smooth peanut butter
6 tablespoons unsalted butter, softened
3/4 cup confections' sugar
3 tablespoons heavy cream

To make the cookie dough

In a medium bowl, whisk together flour, baking soda and salt.

In a large mixing bowl, beat together butter, peanut butter and sugars until light and fluffy. Add the egg and vanilla - mix until combined. Add the dry ingredients and mix on low just until combined. Divide the dough in half, flatten into a disk and cover with saran wrap - refrigerate at least 30 minutes.

Preheat oven to 325

Working with one piece of dough at a time, roll the dough out onto a lightly floured surface until it is roughly 1/4" thick. Using a rectangle cookie cutter, cut out as many cookies as you can - if you don't have a cookie cutter like this, you could just use a sharp knife to cut the dough into 2 1/2" x 1" rectangles. Gently move the cookies to parchment lined baking sheets - use the tines of a fork to score lines into the top of each cookie. Cover pan and place in the refrigerator until the cookies are firm, about 15 minutes. Repeat process with any remaining dough.

Bake until the cookies are lightly golden around the edges and firm in the center, about 12 to 16 minutes. Remove and transfer cookies to a wire rack to cool completely.

For the filling

In a large mixing bowl, add peanut butter, butter, confectioners' sugar and heavy cream. Mix until light and fluffy, about 3 to 5 minutes - be sure to scrape the bowl a couple times to make sure everything is incorporated.

To assemble

Scoop about 1 tablespoon of the filling on the flat sides of one half of the cookies - place the remaining cookies on top of the filled cookies (flat side to flat side) and lightly press to adhere.

For the yield, I got 39 total sandwich cookies.
