Strawberry and Rhubarb Crumble is naturally sweet and bursting with flavor. Simple ingredients form the fruit base, while oats and pecans star in the streusel topping. Served warm with ice cream, this is the ultimate summer dessert. It’s spring in North Carolina, which means rhubarb and strawberries are showing up in grocery stores and maybe at farmers’ markets if you’re lucky enough to live in an areas where it grows, and it’s time to combine them for a strawberry and rhubarb crumble.
