Peanut Butter Sandwich Cookies

Step 1

Preheat oven to 350°F. Line a baking sheet with parchment paper.

Step 2

In a medium bowl, whisk together 1.5 cups flour, 0.5 tsp baking soda, and 0.25 tsp salt.

Step 3

In a large bowl, beat 0.5 cup softened butter, 0.5 cup creamy peanut butter, and 0.5 cup brown sugar until creamy, about 2 minutes.

Step 4

Beat in 1 egg and 1 tsp vanilla extract until combined.

Step 5

Gradually add the flour mixture, mixing until just combined. Dough will be soft.

Step 6

Roll dough into 1-inch balls and place 2 inches apart on the baking sheet. Flatten each with a fork, making a crisscross pattern.

Step 7

Bake until edges are lightly golden, 10-12 minutes. Cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.

Step 8

Spread a thin layer of peanut butter on the flat side of one cookie, then top with another cookie to form a sandwich. Repeat with remaining cookies.
