Strawberry Rhubarb Bars

Strawberry Rhubarb Bars combine a crumbly oat and flour crust with a sweet-tart filling made from fresh strawberries and rhubarb. The bar features a bottom crust, a fruit filling tossed with sugar and cornstarch, and a crisp, golden crumb topping. Baking until the filling bubbles and the top turns golden creates a chewy yet crisp texture balance. These bars are ideal for serving as a handheld dessert or snack, showcasing the seasonal flavors of rhubarb and strawberry together in a convenient bar form.

Description

Strawberry Rhubarb Bars consist of a layered base and topping made from a blend of all-purpose flour, rolled oats, sugars, baking soda, salt, melted butter, and vanilla. The filling is crafted by tossing chopped strawberries and sliced rhubarb with fresh lemon juice, sugar, and cornstarch to create a thickened fruit mixture. After pressing two-thirds of the crumb mixture into a prepared pan, the fruit filling is spread evenly atop. The remaining crumb mixture is sprinkled over the top. Baking at a moderate temperature until the filling bubbles and the crumbs turn golden yields bars with a tender, chewy fruit center and crisp textured crust layers. These bars can be lifted from the pan if parchment is used or served directly from the baking dish.

The flavor combines the bright tartness of rhubarb with the sweetness of strawberries, balanced by the rich buttery crumb. The oat content adds a nutty chew and texture depth. This treat works well as a seasonal dessert or sweet snack and can be enjoyed warm or cooled.

If parchment paper is not used, you can butter the baking dish only, but bars will be easier to remove if lined with parchment. The recipe yield corresponds to a 9x9 inch pan.

  2. In a mixing bowl whisk together flour, baking soda and salt. Add in oats, brown sugar and granulated sugar and whisk to blend, while using fingertips to break up small clumps of brown sugar.

Notes

  • Butter and parchment paper help bars lift cleanly from the pan for easier cutting and serving.
  • If you prefer, skip the parchment and butter the dish only, though bars may be harder to remove.
