Step‑by‑Step Instructions for Strawberry Rhubarb Crumb Bars Recipe
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats, grease a 9×13 baking dish or line it with parchment paper for easy removal later. This initial step is crucial to ensure an even bake for your delicious Strawberry Rhubarb Crumb Bars.
Step 2: Mix Fruit Filling
In a mixing bowl, combine chopped strawberries and rhubarb, adding sugar, cornstarch, and freshly squeezed lemon juice. Gently toss the mixture until the fruit is evenly coated with the ingredients, then allow it to sit for about 10 minutes. This resting time helps the flavors meld together beautifully for the filling.
Step 3: Prepare Crumb Mixture
In a large bowl, whisk together flour, oats, brown sugar, cinnamon, baking powder, and salt. Next, cut in the cold, cubed butter using a pastry cutter or your fingertips until the mixture resembles coarse crumbs. This crumb mixture will serve as both the crust and the topping for your Strawberry Rhubarb Crumb Bars.
Step 4: Assemble Bars
Take about two-thirds of your crumb mixture and evenly press it into the bottom of the prepared baking dish. Ensure it forms a solid foundation for your bars. Layer the fruit filling on top, spreading it out smoothly to cover the crust. This step creates a delightful contrast between the crumb and the juicy filling.
Step 5: Top and Bake
Sprinkle the remaining crumb mixture evenly over the fruit layer, allowing the top to be generously covered. Place the baking dish in the preheated oven and bake for 40 to 45 minutes, or until the topping is golden brown and the filling is bubbly. Keep an eye on the visual cues as the crust develops a lovely golden hue.
Step 6: Cool and Slice
Once baked, remove the pan from the oven and let it cool completely in the dish. This cooling period is essential for allowing the bars to set properly. After about an hour or so, slice into squares with a sharp knife, making clean cuts to maintain the structural integrity of your Strawberry Rhubarb Crumb Bars.
