Step 1

Preheat the oven to 350 degrees Fahrenheit (175°C). Grease two baking sheets with nonstick spray or line them with parchment paper.

Step 2

In a large bowl, beat the butter, brown sugar, and granulated sugar with an electric mixer at medium speed until light and fluffy, about 5 minutes. Beat in the egg, vanilla, and pumpkin.

Step 3

Sift the flour, cinnamon, baking soda, baking powder, and salt in a separate bowl. Gradually pour the dry ingredients into the butter-sugar mixture and gently mix until well combined. Gently mix in the walnuts.

Step 4

Drop scoops of cookie dough onto the prepared baking sheets, allowing for a 2-inch space in between.

Step 5

Bake for 8 to 10 minutes or until the edges are lightly browned. Cool on wire racks.

Step 6

Meanwhile, make the frosting. In a bowl, beat the butter, vanilla, and cream cheese until smooth and lump-free. Gradually add the powdered sugar and beat until smooth and creamy.

Step 7

Spread frosting over the cooled cookies. Serve and enjoy!
