Rich, chewy chocolate cookies sandwiched with a layer of spiked peppermint chocolate ganache make a fun, festive holiday treat. (Can also be made alcohol-free; see notes)
*If you want to avoid the alcohol in this recipe, you can replace the Kahlua in the ganache with an equal amount of heavy cream and add a bit of peppermint extract.
**Linzer cookie sets are pretty easy to find and fairly cheap. I have this set from World Market, but there are also plenty available on Amazon. Alternatively, you can use a regular cookie cutter to cut the cookies along with a smaller cutter to cut out the centers for the tops. Another option would be to just skip the center cutout completely and scatter the sprinkles over the white chocolate before it sets.
***If you can't fit both cookie sheets in your freezer at once, put the second sheet in the refrigerator if possible while the first is in the freezer, and freeze the second sheet while the first batch is baking.
