These festive cookies feature a tender buttery dough layered with a creamy blueberry cream cheese filling, perfect for celebrations like the Fourth of July or summer picnics.
If dough feels too sticky, chill for 15 minutes before rolling. Pat blueberries dry to avoid soggy cookies. Do not cut all the way through the dough when making flag stripes to keep cookies intact. Watch oven closely to prevent over-browning; tent with foil if needed. Dough can be refrigerated up to 2 days; filling best fresh but can be refrigerated for 1 day.
