My lemon & blueberry thumbprint cookie recipe is made using healthier ingredients than traditional thumbprint cookies. In this recipe, I use coconut oil in place of butter, raw sugar (or coconut sugar) in place of regular white sugar and St. Dalfour's blueberry fruit spread which is made from 100% fruit and with no additives, cane sugars or preservatives. TIP: For an even healthier option, omit the lemon icing.
