💡 Tips
Keep the lid closed while cooking—slow cookers lose a lot of heat when opened.
Frozen blueberries work well because they release juices as they cook.
For a crunchier topping, transfer a portion to a baking dish and briefly broil (optional).
✨ Bottom Line
This lemon blueberry dump cake is the ultimate “set it and forget it” dessert: sweet blueberries, bright lemon flavor, and a buttery cake topping with almost no effort. 🍋🫐🍰
