Eggnog Thumbprints

These cookies capture the flavor of eggnog in cookie form. The base is a tender, buttery shortbread thumb-pressed to make a well, then filled with a fluffy rum-laced buttercream and finished with a dusting of fresh-grated nutmeg. They’re the kind of cookie that makes a holiday tin feel intentional rather than thrown together.

Chilling the dough is a step you can’t skip. An hour in the fridge solidifies the butter so the dough holds its shape during baking and the thumbprint stays defined instead of spreading into a flat disc. Cold dough also handles cleaner when you’re rolling fifty cookies.

The thumb-press technique deserves a second of attention. Press hard enough to make a real well, but not so hard that you crack through to the bottom of the cookie. If cracks form, gently pinch them closed before baking.

For the filling, real rum gives a deeper, more authentic eggnog flavor than the milk-and-extract substitute. Either works, but if you have rum, use it.

Finish with a generous grating of fresh nutmeg over the filled cookies. Pre-ground nutmeg is fine, but the freshly grated version is dramatically more aromatic.

Pro Tips

• Use a measuring teaspoon to portion the filling. It keeps every cookie looking neat and uniform.
• Re-press the thumbprints right after pulling the cookies from the oven. The wells often fill in slightly during baking.
• Let the cookies cool completely before filling. Warm cookies melt the buttercream into a runny mess.
• Whole nutmeg keeps for years and tastes infinitely better than the powdered jar.

Variations

• Swap rum for bourbon or brandy for a different holiday liquor.
• Add a quarter teaspoon of cinnamon to the dough for warmer spice.
• Drizzle the tops with melted white chocolate for extra holiday flair.
