With a chocolatey coconut base, a creamy custard icing in the middle, and more chocolate on top, Nanaimo bars are an iconic Canadian treat.

Each bite of this easy shortbread is rich and buttery, with a tender, crumbly texture that melts in your mouth. Plus: The dough takes just five minutes to make and it practically comes together in one bowl.

Thanks to the magic of cast iron, classic chocolate chip cookie dough bakes up extra chewy and crisp around the edges. With a few teaspoons of malted milk powder for an extra layer of flavor, it's a rich and chocolaty dessert just begging for a scoop of ice cream—or at least a glass of milk.
