The tray comes out with neat little wells, but those centers aren’t finished yet. A Hershey’s Kiss pressed into each warm cookie settles into the dough and gives every bite a soft chocolate center. That timing is what makes these Hershey Kiss Thumbprint Cookies feel like more than a plain butter cookie with candy on top.
The dough is simple: butter, sugar, one egg yolk, vanilla, flour, and salt. I mix it only until it gathers into a soft dough, then roll it into even balls so the cookies bake at the same pace. The thumbprint should be shallow before baking; the warm cookies are easy to deepen gently if a Kiss needs a little more room. Once cooled, the cookies have tender, lightly golden edges and a firm chocolate center.
Kitchen Note
Unwrap all 24 Kisses before the cookies go into the oven. They need to be ready at hand so you can press one into each cookie while the tray is still hot.
Save these Hershey Kiss Thumbprint Cookies for a buttery cookie with a chocolate center in every bite.
These Thumbprints Stay Tender Because They Don’t Need to Rise
There’s no baking powder or baking soda in this dough, so don’t expect a puffy cookie. The soft, buttery dough is meant to hold its shape, leaving a small well for the chocolate instead of spreading into a domed top. That’s also why the indentation should be shallow before the tray goes into the oven. A deep press can split the dough or make the center too thin.
The thumbprint doesn’t have to be perfectly deep at the start. After baking, the cookies are warm and pliable, so you can gently deepen a center just enough to seat its Kiss. Work lightly; the goal is to make room, not push through the bottom of the cookie. This two-part approach keeps the cookies intact while giving the chocolate a stable place to sit. The finished texture is closer to a tender butter cookie than a cakey one, with the candy adding the soft, chocolatey center.
Why the Yolk, Butter, and Chocolate Each Matter
- Unsalted butter — Softened butter beats smoothly with the sugar and gives the cookies their tender, rich crumb. It should yield when pressed but shouldn’t look melted or greasy; melted butter won’t cream the same way.
- Granulated sugar — It sweetens the dough and helps the edges take on a little color as they bake. The plain granulated kind is the right fit here; a liquid sweetener would change how the dough comes together.
- Egg yolk — The yolk binds the flour and butter while keeping the dough rich. Using only the yolk matters: adding the white brings extra moisture and can change the cookie’s texture.
- All-purpose flour — Flour gives the dough enough structure to hold its thumbprint. Mix it in only until the dough comes together; additional mixing after the flour is incorporated can make butter cookies tougher.
- Vanilla extract — Vanilla rounds out the buttery dough without competing with the chocolate. Use the extract you keep for baking; there’s no need for a specialty bottle.
- Hershey’s Kisses milk chocolates — Their familiar shape fits the center, and pressing them into warm cookies lets them settle in place. Unwrap them before baking so the chocolate can go straight onto the hot cookies.
From Soft Dough to Set Chocolate Centers
Cream the Butter and Sugar Until Smooth
Heat the oven to 350°F and line an 18×13-inch baking sheet with parchment paper. Beat the softened butter and granulated sugar in a medium bowl for about 2 minutes, until creamy. Add the egg yolk and vanilla, then beat them in until combined. If the butter is still cold and lumpy, give it a little more time to soften rather than trying to force the mixture smooth.
Bring the Dough Together and Shape the Wells
Add the flour and salt, mixing just until a soft dough forms. Stop as soon as the loose flour disappears; the dough shouldn’t be beaten until elastic. Roll it into 24 balls, about 1 tablespoon each, and arrange them 2 inches apart on the lined sheet. Press a shallow indentation into each center with your thumb so the dough remains sturdy around the well.
Bake Until the Edges Just Begin to Color
Bake for 10–12 minutes, until the cookies are set and just beginning to turn golden at the edges. They don’t need to become deeply browned; pale tops and lightly colored edges are the cue to take the tray out. While they’re warm, gently deepen any indentation that needs a little more room, then press one Hershey’s Kiss into each center. Let the cookies cool on the baking sheet for 5 minutes before moving them to a wire rack to cool completely.
Two Easy Ways to Change the Chocolate or Dough
Use Dark Chocolate Kisses
Replace each milk chocolate Kiss with a dark chocolate Hershey’s Kiss. Keep the same one-per-cookie amount and press them into the cookies while warm; the darker chocolate gives the sweet, buttery cookie a less-sweet finish.
Make a Gluten-Free Batch
Swap the all-purpose flour for a cup-for-cup gluten-free baking blend that contains xanthan gum. The dough may feel a little more delicate, so roll the balls gently and avoid overworking them. The buttery cookie and chocolate center stay true to the original style.
Storage and Reheating
- Refrigerator: Refrigeration isn’t needed. Keep the fully cooled cookies in an airtight container at room temperature for up to 5 days; the chocolate centers will firm up as they sit.
- Freezer: Freeze fully cooled cookies in a single layer until firm, then pack them in an airtight freezer-safe container for up to 2 months. Thaw at room temperature before serving.
- Reheating: These are best at room temperature, so skip reheating; warming them can soften the chocolate centers and make them messy to handle.
