I needed a chocolate cut out cookie for the Baby’s BATMAN themed party (recap, here). A full size Gotham City Cake & fondant Batman cupcakes weren’t enough obviously, because I need to theme out everything. EVERYTHING.
1 3/4 cups all-purpose flour
1/4 cup Valrhona cocoa powder
1/2 teaspoon baking powder
1/4 teaspoon coarse salt
1/2 cup (1 stick) butter
1 cup sugar
1 Large egg
1 teaspoon pure vanilla extract
9 ounces semi sweet chocolate chips
1/2 cup heavy cream
Sift flour, cocoa powder, baking powder, and salt into a large bowl. Set aside. Cream butter and sugar with an electric mixer until creamy. Mix in egg and vanilla. Slowly add flour mixture until just combined. Cut dough in half, and wrap them in plastic. Refrigerate about 1 hour.
Preheat the oven to 325 degrees. Roll dough on a lightly floured surface to about 1/8 inch thick. You can use any cookie cutter you like, but bat-wiches are pretty awesome.
Space them about 1 inch apart on baking sheets prepped with parchment paper or silpats. If the dough gets too soft, refrigerate, reroll and cut. Bake about 12 minutes. Cool on on wire racks.
To make the ganache, put the chocolate chips in medium bowl. In a saucepan, bring the cream to a boil. Pour over chocolate; let stand 5 minute, then stir until smooth. I like to chill it in the fridge for a bit, until it becomes spreadable. Maybe about an hour. Spread onto bottom of half the cookies. Sandwich with remaining cookies.
