These buttery bars are bursting with in-season summer blueberries and an unexpected touch of cardamom, making for the perfect twist on your favourite summer dessert. Cardamom is baked into the crumb and topping, while fresh blueberries are cooked down with lemon zest into a simple blueberry preserve that makes for the perfect jammy filling. Plus, you can easily sub in whatever berries you have depending on what’s in season: raspberries, strawberries and blackberries all work well in this recipe. When all the layers come together, it’s pure summer magic.
