- Preheat the oven to 350°F. Line two baking sheets with parchment paper and set aside.  
- Mix the butter with a hand or stand mixer until creamy. Add the sugar and blend until light and fluffy. Stop the mixer and scrape down the sides of the bowl. 
- Add the egg, vanilla, and peppermint. Mix until combined. 
- Add the baking powder, salt, and baking soda. Mix until blended. Add the flour and mix on low speed until the dough comes together. 
- Divide the dough into three equal portions. Mix the coffee, pink dye, and cocoa powder - one into each of the three portions of dough.  
- Scoop about two teaspoons of each dough and roll into a ball. Smoosh them together and give the dough and twist. Roll into a smooth ball and toss in sugar. 
- Repeat with the remaining dough. Place on the lined baking sheets - at lease 2 inches apart. 
- Bake for 10 to 13 minutes. When done, the cookies should be crisp around the edges but still soft in the middle. Use a large round cookie cutter to scoot in any uneven edges.  
- Cool the cookies over a wire rack before serving and storing.
