Use gel food coloring to avoid thinning the dough and start with small amounts to keep colors vibrant without staining hands; wearing disposable gloves helps. Slight underbaking yields a tender, cheesecake-like center, but ensure cookies are sealed well to prevent leakage. If the dough becomes sticky while shaping, pop it back in the fridge for 5 to 10 minutes. For cleaner marbling, avoid over-kneading the colors together and rotate the dough ball as you pinch pieces. The cheesecake filling should be thick; if runny, add 1 to 2 tablespoons more powdered sugar. Cookies freeze well: freeze shaped unbaked balls on a tray, then store in a bag up to 2 months and bake from frozen adding 1 to 2 minutes.
