Better than an ordinary Valentine's card. Much better.
2 cups all-purpose flour
1 tsp baking soda
1 cup butter
3/4 cup granulated sugar
3/4 cup brown sugar
1/2 cup unsweetened cocoa powder
1 tsp vanilla
1 cup semi-sweet chocolate chips
1 cup white chocolate chips
Preheat oven to 350F. Line 2 baking sheets with parchment paper.
In a small bowl, stir together flour and baking soda.
Then, in a large bowl, cream together the butter and the sugars with an electric mixer; add the eggs and beat until light in colour, about a min. Add the cocoa and vanilla, and keep beating until smooth. Add the flour mixture to the wet ingredients and stir. Mix in the semi-sweet chocolate chips, stirring just enough to combine and making sure chips are evenly distributed.
Spoon heaping tbsps of cookie dough onto the pans, shaping each into an exaggerated heart (they will round out a bit as they bake). Bake each pan for 10 to 12 min, until cookies are golden.
When cookies are completely cool, put white chocolate chips into a small, heavy duty, zip-top plastic bag. Put the bag into the microwave and cook on high power for 1 min, then take the bag out and mush it around with your hands to mix. Return it to the microwave and continue melting on high power for 30 sec at a time, taking it out and massaging the bag between each increment, until the chocolate is melted.
Holding the bag in one hand, squish all the melted chocolate down to one corner. Snip off the corner to make a small opening; this will be your piping bag. Add designs or names to each cookie.
Be careful while melting the white chocolate; it has a tendency to burn easily.
