This chocolate kiss cookie is the kind of treat that reappears every holiday season in my kitchen and never fails to bring smiles. I first adapted this version on a busy December afternoon when I wanted the familiar comfort of a peanut butter blossom but craved a deeper chocolate flavor and a softer bite. The result is a tender dark chocolate base — enriched with butter and egg yolks for silkiness — rolled in bright nonpareil sprinkles that give a playful crunch, and finished with a classic Hershey's Kiss pressed into the warm center. The texture is soft and slightly cakey, with an intense cocoa flavor balanced by the sweet chocolate of the kiss.

I remember making a tray for a neighborhood cookie swap; one neighbor declared them the most photogenic cookie she had ever seen, while another admitted she ate three before leaving. Because these hold their shape and travel well when cooled, they became my go-to for gifting. The espresso powder is a small, almost secret ingredient that deepens the chocolate without tasting like coffee. They bake quickly, are forgiving in the mixing bowl, and transform simple pantry staples into something festive and special.

Ingredients

• All-purpose flour: Use 2 cups. Look for a good-quality, unbleached flour; it gives structure without making the cookies tough. King Arthur or a similar brand provides consistent results.
• Dark cocoa powder: 1 cup. Choose Dutch-processed or a high-quality natural dark cocoa for an intense chocolate flavor. I like using a dutch-processed variety for depth.
• Instant espresso powder: 1 teaspoon. This amplifies chocolate notes without adding a coffee taste — use any brand labeled espresso or instant coffee powder.
• Salt: 1/2 teaspoon. Balances the sweetness and brings out the chocolate nuances.
• Unsalted butter: 1 cup (2 sticks), room temperature. Soft but still slightly cool is ideal to create a light, creamy creamed mixture with the sugar.
• Granulated sugar: 1 1/4 cups. Provides structure and a slight crisp edge while the interior remains tender.
• Egg yolks: 2 yolks at room temperature. They enrich the dough, making the crumb soft and tender.
• Milk: 1/4 cup, room temperature. Adds moisture and helps the dough come together; whole milk yields a richer result.
• Vanilla extract: 1 teaspoon. Use pure vanilla extract for the best aromatic lift.
• Holiday nonpareil sprinkles: 1 cup. These tiny round sprinkles adhere well and add a festive texture; choose brand-approved baking sprays to avoid color bleeding.
• Hershey's Kisses: 48 pieces. Classic milk chocolate Kisses are traditional; you can substitute other wrapped chocolate drops if desired.

Instructions

Preheat and prepare pans: Preheat your oven to 350°F (177°C). Line baking sheets with silicone mats or parchment paper so the bottoms bake evenly and cleanup is easier. Position racks in the center of the oven for consistent heat. Whisk dry ingredients: In a medium bowl, whisk together the 2 cups of all-purpose flour, 1 cup dark cocoa powder, 1 teaspoon instant espresso powder, and 1/2 teaspoon salt. Whisking removes lumps in the cocoa and evenly distributes the espresso powder so every cookie has the same depth of flavor. Cream butter and sugar: In a stand mixer with the paddle attachment or using an electric hand mixer in a large bowl, cream 1 cup of room-temperature unsalted butter with 1 1/4 cups granulated sugar until lightened in color and fluffy, about 2 to 3 minutes on medium speed. Scrape the bowl once to ensure even mixing. Add yolks, milk, and vanilla: Add the 2 room-temperature egg yolks, 1/4 cup milk, and 1 teaspoon vanilla extract. Mix on low to medium until fully incorporated; overmixing at this stage can create too much air and change the texture, so mix just until combined. Combine with dry mix: Add the dry mixture to the wet ingredients in two additions, mixing on low speed until a soft dough forms. The dough should hold together but feel soft and slightly tacky—if it seems dry, add a teaspoon of milk at a time until it comes together. Portion, coat, and bake: Use a small cookie scoop (approximately 1 tablespoon) to portion the dough. Roll each portion into a smooth ball, then roll the ball in holiday nonpareil sprinkles until thoroughly coated. Place the dough balls about 1 1/2 inches apart on prepared pans. Bake for about 10 minutes; the cookies should look set at the edges but still slightly soft in the center. Top with chocolate and cool: Remove the pan from the oven and immediately press a Hershey's Kiss into the center of each warm cookie, twisting slightly to set. Cool on the baking sheet for 2 minutes, then transfer to a wire rack to cool completely so the bottoms finish setting.

Storage Tips

To keep the cookies at their best, store completely cooled cookies in an airtight container at room temperature for up to 3 days. For longer storage, arrange cookies in a single layer or separated by parchment, and freeze for up to 3 months. When freezing, I like to flash-freeze on a tray first so the sprinkles and Kiss don't stick together; once solid, stack with parchment between layers. To refresh slightly soft cookies, warm them in a 300°F oven for 3 to 4 minutes.

Ingredient Substitutions

If you don’t have dark cocoa, use natural unsweetened cocoa but reduce baking time by 1 minute to prevent dryness. You can swap the milk for buttermilk thinned with a tablespoon of water for tang and richness, though expect a slightly softer crumb. For a dairy-free version, use a vegan butter substitute and dairy-free chocolate kisses, but texture will be a touch different. If holiday nonpareils are not available, roll in colored sanding sugar or finely chopped toasted nuts for contrast.

Serving Suggestions

Serve the cookies on a simple white platter so the sprinkles pop visually. They pair beautifully with hot cocoa or a bold espresso for adult gatherings. For gift tins, layer cookies with pieces of wax paper and add a sprig of rosemary or a ribbon for a homey touch. Turn them into a dessert board center by placing them next to salted caramel squares and shortbread for a variety of textures.

Seasonal Adaptations

For Valentine’s Day swap the sprinkles for heart-shaped nonpareils and use red-wrapped Kisses. In autumn, roll the dough in a cinnamon-sugar blend and top with caramel-filled chocolates. For a winter party, add a pinch of ground ginger and roll in gold or silver sanding sugar for an elegant sheen. These small swaps let you adapt the same dough to any holiday without changing the basic technique.

Meal Prep Tips

If you’re prepping for a cookie exchange or party, portion the dough into 1-tablespoon balls and freeze them on a tray. Once frozen, transfer to labeled freezer bags; bake straight from frozen, adding 1 to 2 minutes to the bake time. This makes it easy to bake fresh trays a few hours before guests arrive. I also recommend storing uncoated dough balls and rolling in sprinkles right before baking to keep colors vibrant.

Success Stories

One holiday I made a batch for a school bake sale; they were the first to disappear and parents came back asking for the recipe. Another time a friend used the cookies in a cookie swap and won the “most creative” ribbon thanks to the contrast of the dark cookie and bright sprinkles. These small victories are why I keep this recipe in my holiday rotation — it’s reliable and receives compliments every time.

Whether you bake a single tray or a double batch for gifts, these cookies are an easy way to make holidays feel more connected and celebratory. I hope you make them, share them, and make a few new memories around the oven this season.
