Dark cocoa sugar-cookie sandwiches with a pale mint buttercream layer.
The feature to preserve is the shaping: Cut thirty-six 2-inch rounds from chilled ¼-inch dough. Bake twelve halves per tray, 2 inches apart, then match into eighteen pairs.
Before mixing, measure without packing the flour. Use culinary peppermint extract. A little flavors the filling; oil is much more concentrated and is not an equal replacement.
Use the observable baking cues as well as the timer. Beat filling butter and sugar smooth, add milk and peppermint, and beat thick. Add optional tiny green gel-color drop. Sandwich cooled halves with a modest teaspoon.

Instructions
Mixing
- Make the doughCream butter and sugar until smooth. Beat in egg and vanilla. Whisk flour, cocoa, baking powder and salt, then mix into the wet ingredients on low until combined.
Thermal management
- Prepare for shapingRoll the freshly mixed dough between lightly floured parchment sheets to ¼ inch thick, cover and refrigerate until firm for the stated chilling time. Keep the second slab refrigerated while cutting the first.
Shaping
- Shape the batchCut thirty-six 2-inch rounds from chilled ¼-inch dough. Bake twelve halves per tray, 2 inches apart, then match into eighteen pairs.
Baking
- Bake to the right texturePreheat to 350°F (175°C). Bake on the center rack for 11–12 minutes. Edges should be set and only lightly colored; centers must lose their wet sheen. Use cool pans for subsequent trays.
Cooling
- Cool before servingRest on the baking sheet for 5 minutes, then move to a rack. Allow about 20 minutes total cooling before storing; the center firms as steam escapes.
Finishing
