Valentine's Oreos

Directions

1. In a food processor mix together sugar, brown sugar, flour, cocoa, baking soda and salt. Add the butter a few pieces at a time, with the motor running. Pulse to incorporate. Add the egg and vanilla. Pulse until the dough starts to form. Turn the dough onto a clean surface. Form into a disk. Wrap in plastic wrap, and chill for at least an hour.
2. Preheat oven to 350 degrees. Cut the dough in half. Roll out on a lightly floured surface to about 1/8 in thick. Cut into desired shape. Place on a lined baking sheet. Bake for 12 to 15 minutes, the cookies should look dry. Cool cookies in a wire rack.
3. To prepare the filling beat together butter, vanilla and salt until fluffy. Add sugar and beat until fully incorporated. Add milk 1 Tbls at a time and beat until the desired consistency. Spoon or pipe filling into the center of a cookie. Top with another cookie, pressing down gently to spread the filling to the edge.
