Peppermint Nanaimo Bars

Blending the flavors of a wintry mocha with a Canadian classic, these Nanaimo bars receive a boost from an espresso-spiked ganache, a dose of peppermint extract, and a lightly spiced cinnamon filling. At the base, rich macadamia nuts and sweet coconut flakes add a satisfying element of chew. For more cookie recipes from around the world, check out our 2018 Holiday Cookies special issue
