These blueberry lemon bars feature a buttery shortbread crust with a zesty lemon custard and fresh blueberries, perfect for summer celebrations and easy to make.
Keep butter cold when making crust for best texture. Avoid white pith when zesting lemons. Fold blueberries gently to avoid crushing. Chill bars for at least 2 hours before slicing for clean cuts. Frozen blueberries can be used but should be thawed and drained first. Tent crust with foil if browning too fast.
