These peppermint blossom cookies are a holiday favorite!!! We love the rich and soft chocolate cookie (that has a hint of peppermint extract) that's then topped with a peppermint candy kiss. These are the perfect Christmas cookie!
Preheat oven to 375°F. Line a baking sheet with parchment paper and set aside.
In the bowl of a stand mixer fitted with a paddle attachment cream the butter, brown sugar, and 1/3 cup granulated sugar on medium speed for 1-2 minutes.
Add the egg, milk, peppermint extract, vanilla extract and mix to combine.
Add the all-purpose flour, Dutch process cocoa powder, cornstarch, baking soda, and salt and mix until the dough comes together and no flour streaks remain.
Place 3 T granulated sugar in small bowl. Using a 2 tsp sized cookie scoop portion the cookie dough into 1 inch sized balls. Roll each cookie dough ball into the sugar and place on the prepared baking sheet 2 inches apart.
Bake for 6-7 minutes. Remove from the oven and immediately press a peppermint chocolate kiss into the center of each cookie. Let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Notes
Store leftover cookies in an airtight container at room temperature for 3-5 days.
