These buttery, crumbly shortbread cookies are filled with fresh blueberries and topped with a luscious creamy frosting, perfect for a comforting and special treat.
If blueberries bleed too much, toss them lightly in flour before folding into the dough to keep dough color uniform. Do not overmix dough after adding flour to avoid tough cookies. Chill dough for at least 30 minutes to prevent spreading. Use room temperature ingredients for frosting and sift powdered sugar to avoid lumps. Adjust frosting consistency with milk if needed.
