Double Chocolate Kisses Cookies

Directions

1. Heat oven to 375 degrees F. Beat butter, sugar, egg, and vanilla in a large bowl until smooth.
2. Combine flour, cocoa, baking soda, and salt in a separate bowl. Alternately beat flour mixture into butter mixture with milk until fully combined. Cover dough and chill for 1 hour.
3. Form dough into 1-inch round balls and place on a cookie sheet. Bake 8 to 10 minutes, or until set. Let cool 1 minute and move cookies to a wire rack. When cool, spread frosting on cookies and top each with Hershey's kiss.
