These summer berry parfaits are a light and refreshing dessert, filled with fresh blueberries swirled in strawberry jam, a creamy Greek yogurt-melted marshmallow filling, and a homemade crumble topping. When it’s hot outside, a chilled, fruity dessert is the perfect way to cool off. I especially love this dessert because it encompasses so many different textures, all in one cup. The tender burst of flavor from the blueberries, the thick creaminess of the sweet-tart filling, and the sweet crunch of the topping all combine to make a very pleasant treat.
