This Blueberry Cream Cheese Coffee Cake combines a tender sour cream cake base with a tangy cream cheese filling, fresh blueberries, and a buttery streusel topping. Perfect for brunch or a cozy afternoon treat, it's an easy summer dessert that feels special.
For best results, use room temperature cream cheese to avoid lumps. Tossing blueberries in flour prevents sinking. If using frozen berries, keep them frozen and add straight to the flour mixture. Store covered at room temperature for up to 2 days or refrigerate for up to 5 days. Freeze wrapped for up to 3 months.
