Chocolate Blossom Cookies are a rich, chocolatey spin on classic peanut butter blossoms. These chewy cookies, crowned with a Hershey’s Kiss, make a perfect addition to holiday trays or a sweet treat for Valentine’s Day.
In a large mixing bowl, beat the butter and sugars on medium-high speed until smooth and fluffy, about 3 minutes. Add the egg and vanilla and mix for another minute.
Sift in the flour, cocoa powder, baking soda, and salt. Mix until just combined. Do not overmix. The dough will be sticky. Use a spatula to flatten the dough in the bowl (so it chills faster). Chill 30-60 minutes.
Place Hershey's Kisses in the freezer to help them keep their shape when baked. Preheat oven to 350 and line baking sheets with parchment paper.
Roll 1-tablespoon portions of dough into 1-inch balls and roll them in sugar. Place 2 inches apart on prepared baking sheets. Bake 8-10 minutes or until the edges are set and the centers are puffy.
Immediately and gently press a Hershey's Kiss about halfway down the center of each cookie, then transfer cookies to a wire cooling rack. The Hershey's Kisses will soften and firm up again, so allow a couple of hours to cool completely.
Notes
For the richest flavor, use dark brown sugar and dark cocoa.
Whisk the dry ingredients instead of sifting.
If the dough is sticky, chill it longer.
Freeze Hershey's Kisses to prevent melting.
Milk chocolate kisses hold their shape better than dark chocolate
Chocolate cookies are done when edges set, centers puff, and the internal temp is 190-200°F. I go on the lower side for fudgier cookies.
