Peanut Butter-Oatmeal Sandwich Cookies

Instructions

Make the cookie dough

Preheat the oven to 350°F (180°C). Lightly butter (or line with parchment) two rimmed baking sheets.

In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl using a hand mixer, beat together the butter, peanut butter, sugars, baking soda, baking powder, salt, and vanilla. Add the egg, beating until light and fluffy. Stir in the flour and oats.

Drop the dough by the heaping teaspoonful onto the prepared baking sheets (a cookie scoop works well here). Use the bottom of a lightly buttered drinking glass to press each cookie to about 1/4-inch (6-mm) thick. TESTER TIP: If the dough is a little crumbly when you scoop it, roll it between your palms to make a smooth ball.

Bake the cookies until very light golden brown, 8 to 10 minutes. Remove them from the oven and transfer to a rack to cool.

Make the peanut butter filling

In a small bowl, use a hand mixer or a wooden spoon to beat together the peanut butter, honey, and confectioners' sugar until smooth.

Assemble the cookies

When the cookies are cool, use an offset spatula to spread half of them with the filling. Top the filling with the remaining cookies, pressing together gently.
