Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and grease a 9×9-inch baking pan or line it with parchment paper for easy removal.
Step 2: Prepare the Oatmeal Crust
In a large mixing bowl, combine rolled oats, all-purpose flour, brown sugar, granulated sugar, baking soda, and salt. Stir until well mixed. Then, add the melted butter and vanilla extract. Mix until the mixture resembles coarse crumbs. Reserve about 1 cup of this mixture for the topping.
Step 3: Make the Rhubarb Filling
In another bowl, combine chopped rhubarb, cornstarch, and remaining granulated sugar. Toss to coat the rhubarb evenly with the mixture. This will help thicken the filling as it bakes.
Step 4: Assemble the Bars
Press the remaining oatmeal mixture firmly into the bottom of the prepared baking pan to form the crust. Spread the rhubarb filling evenly over the crust, then sprinkle the reserved crumb mixture on top.
Step 5: Bake
Place the baking pan in the preheated oven and bake for 35-40 minutes, or until the top is golden brown and the rhubarb is bubbly. Allow the bars to cool in the pan before transferring them to a wire rack to cool completely.
Step 6: Serve
Once cool, cut into squares and dust with powdered sugar if desired. Serve as a dessert, snack, or a delightful addition to your brunch table!
