Ingredients
Method
Make the cookies
- Beat the butter and 1/2 cup sugar for 2 minutes until fluffy. Beat in the egg yolk, milk and vanilla.
- Whisk the flour, cocoa and salt, then mix into the butter mixture on low speed until a soft dough forms.
- Cover and refrigerate for 30 minutes.
- Heat the oven to 350°F (175°C) and line baking sheets with parchment.
- Roll 1-tablespoon balls, roll them in sugar and place 2 inches apart. Press a well into each with a 1/2-teaspoon measuring spoon.
- Bake for 10 to 12 minutes, until set at the edges. Immediately re-press the wells, cool 5 minutes on the pan, then cool completely on a rack.
Fill
- Heat the cream until steaming and pour over the white chocolate. Let stand 2 minutes, then stir until smooth. Stir in the peppermint extract.
- Spoon the ganache into the cooled cookies and sprinkle with crushed candy cane.
- Let the cookies stand for 30 minutes, until the filling is set.
