Ingredients
Method
- Preheat oven to 350°F (180°C) and line baking sheets with parchment paper.
- Whisk flour, baking soda, salt, and cream of tartar in a bowl.
- Cream butter on medium speed until smooth, then beat in sugar until light and fluffy.
- Add egg and mix just until combined.
- Mix in cocoa powder, red food coloring, and vanilla until evenly colored.
- Add dry ingredients and mix on low speed until just combined.
- Form dough into 3 oz balls and place 4 per baking sheet.
- Bake 8 minutes, remove pan, lift and bang gently on oven rack.
- Return to oven and repeat pan-banging every 2 minutes, 2–3 times.
- Total bake time should be 13–16 minutes with soft centers.
- Cool cookies on pan for 10 minutes, then transfer to rack to cool completely.
- Whisk icing ingredients until smooth.
- Dip half of each cookie into icing and decorate as desired.
Notes
Pan-banging creates rippled edges and soft centers. Cookies should look slightly underbaked in the center when removed from the oven.
