Joshua Weissman's Homemade Oreos (But Better)

Whisk together all-purpose flour, black cocoa powder, baking soda, and salt in a medium bowl.

In a stand mixer, beat softened butter and granulated sugar until fluffy and pale.

Add egg and vanilla extract; mix until smooth.

Gradually add dry mixture on low speed until a dark, cohesive dough forms.

Roll dough out between two sheets of parchment paper to ⅛-inch thickness; chill in freezer for 20 minutes.

Preheat oven to 350°F (175°C). Cut dough into 2-inch rounds and arrange on baking sheets.

Bake for 9 to 10 minutes until crisp. Cool completely on wire racks.

For filling: Beat softened butter, powdered sugar, and vanilla until smooth and spreadable.

Pipe or spoon filling onto half the cookies and sandwich with remaining tops.
