Step 1

Preheat the oven to 350°F (180°C). Line a baking sheet with parchment paper (or use a nonstick pan).

Step 2

Make the cookies: In a large bowl, beat together the peanut butter, maple syrup, and flour with an electric hand mixer until smooth.

Step 3

Roll the dough into ½-inch (1 ¼ cm) balls. Arrange the balls on the prepared baking sheet, placing 2 balls side-by-side for each cookie. Use a fork to create a criss-cross pattern on top of the cookies to create peanut shapes.

Step 4

Bake the cookies for 12 minutes, or until edges are starting to turn golden brown. Let cool completely.

Step 5

Meanwhile, make the frosting: In a large bowl, whip the peanut butter and butter with an electric hand mixer until combined. Add the powdered sugar and beat until combined. Add a bit of water as needed to achieve a smooth consistency.

Step 6

Spread a little bit of the frosting on the underside of 1 of the cookie, then sandwich with another cookie. Repeat with the remaining cookies and frosting.

Step 7

Enjoy!
