Rhubarb Blueberry Oatmeal Bars
Description
Rhubarb Blueberry Oatmeal Bars combine fresh blueberries and rhubarb, cooked with lemon juice, sugar, and cornstarch until thick and smooth to create a bright fruit layer. The base and crumb topping are made from quick-cooking oats, all-purpose flour, brown sugar, baking soda, salt, and cold butter cut in to resemble coarse crumbs.
Half of the oat mixture is pressed into a prepared baking pan, the thickened fruit filling spread on top, then the remaining oat topping gently pressed over the fruit. Baking at 350°F until golden produces bars with a firm crust and slightly chewy texture around the fruit layer. Cooling completely is essential for clean slicing into 24 squares.
These bars work well for gatherings or as a make-ahead treat, showcasing the bright tartness of rhubarb paired with sweet blueberries in a satisfying oat crumble form.
