Valentine's Chocolate Cookies

As Valentine's day nears, the demand for chocolate rises.  Here's the cookies I baked using Dove milk and dark chocolate hearts.

Valentine's Chocolate Cookies

1/2 cup butter, softened
1/2 cup dark brown sugar
1/4 cup sugar
1 large egg
1 tsp vanilla 
1/2 tsp salt
1 tsp baking soda
1 cup flour
1/4 cup dark cocoa
24 Dove chocolate hearts, unwrapped.

Cream together butter and sugars.  Add in egg and vanilla.  Gradually stir in salt, baking soda and flour.  Fold in dark cocoa.  Make sure it is completely mixed in or your cookies will have stripes. Bake on parchment lined baking pans at 350° for 10 minutes.  Remove from oven and press a chocolate heart in the center of each cookie.  Let cool completely.
