Step‑by‑Step Instructions for Amish Oatmeal Rhubarb Bars
Step 1: Prepare the Crumb Base
In a large mixing bowl, combine oats, flour, salt, baking soda, and brown sugar. Cut in cold, cubed butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs, about 5 minutes. Set aside one-third of the mixture for the topping. Press the remaining mixture firmly into the bottom of a greased 9×13-inch pan to form a uniform base.
Step 2: Make the Rhubarb Filling
In a medium saucepan, cook the chopped rhubarb with sugar, cornstarch, and water over medium-high heat. Stir frequently and continue cooking for 5 to 10 minutes until the rhubarb breaks down and the mixture thickens and becomes glossy. Remove from heat and stir in vanilla and ground cinnamon, allowing the filling to cool slightly before spreading.
Step 3: Assemble the Bars
Spread the prepared rhubarb filling evenly over the pressed crumb base in the pan, ensuring it covers the surface entirely. Crumble the reserved topping mixture over the rhubarb layer, making sure to distribute it evenly for a nice crunch. This will create a delicious contrast when you bite into the finished Amish Oatmeal Rhubarb Bars.
Step 4: Bake
Preheat your oven to 350°F (175°C). Place the assembled bars in the oven and bake for 30 to 40 minutes, or until the topping is golden brown and the filling starts to bubble around the edges. For even baking, rotate the pan halfway through the cooking time, ensuring that all sides brown evenly for a perfect finish.
Step 5: Cool and Slice
Once baked, remove the pan from the oven and let the bars cool in the pan for 1 to 2 hours. This cooling period is crucial for achieving clean slices when you cut into the bars. Once they have cooled, carefully slice them into squares or rectangles, ready to serve and enjoy the delicious Amish Oatmeal Rhubarb Bars.
