- 2 tablespoons cocoa (or cacao) nibs (see Notes)
- 6 tablespoons butter, softened
- 1/2 cup sugar, plus extra for sprinkling cookies
- 1 large egg
- 1/2 teaspoon vanilla
- 1 1/3 cups all-purpose flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- Melted semisweet or bittersweet chocolate
Preheat oven to 400°. In a blender, whirl cocoa nibs until each is about the size of a grain of rice.
In the large bowl of an electric mixer, beat butter and 1/2 cup sugar until creamy; beat in egg and vanilla.
In another bowl, whisk together flour, baking powder, salt, and cocoa nibs; gradually add to butter mixture, blending thoroughly, to form a soft dough. Divide dough into thirds, cover each portion tightly with plastic wrap, and refrigerate until firm (at least 1 hour), or up to 3 days.
On a floured board, roll out dough, a portion at a time, to a thickness of 1/8 in. (keep dough refrigerated when not in use). With a sharp knife, cut out free-form tombstone shapes (about 1 1/2 by 3 in.; cut bottom edges at an angle to make them easier to poke into the pots de crème), and place slightly apart on ungreased baking sheets. Sprinkle generously with sugar.
Bake cookies until edges are lightly browned, about 8 to 10 minutes. Transfer to racks and let cool completely before handling.
Using a pastry bag with a very fine tip, pipe the letters "RIP" in chocolate on at least 8 of the cookies. Stick these cookies into the Dark Chocolate Graveyard Pots de Crème and serve the rest of the cookies alongside.
