Kardemummakakor is a classic Swedish cookie built around ground cardamom and, interestingly, ammonium carbonate, also known as hartshorn, a leavening agent that predates baking soda and baking powder entirely and was traditionally made from ground deer antlers. It’s that old-school ingredient that gives these cookies their distinctively light, crisp snap, a texture you just can’t quite replicate with modern leaveners.
You can absolutely enjoy them on their own, but paired with a coffee or hot chocolate, they’re fantastic, that warm cardamom spice playing perfectly against a hot drink. You know the best part? They’re super easy to make and can be done start to finish in less than 45 minutes.
