Step‑by‑Step Instructions for Strawberry Rhubarb Crumb Bars Recipe
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare a 9″x13″ baking dish by greasing it lightly or lining it with parchment paper for easy removal later. This ensures that your Strawberry Rhubarb Crumb Bars will not stick and will bake evenly.
Step 2: Prepare the Fruit Filling
In a spacious mixing bowl, combine chopped strawberries, diced rhubarb, sugar, cornstarch, and a splash of lemon juice. Toss everything together until the fruit is well coated and the sugar starts to dissolve. Allow the mixture to sit for about 10 minutes, letting the flavors meld and the natural juices seep out for a beautifully rich filling.
Step 3: Make the Crumb Mixture
In another large bowl, whisk together flour, oats, brown sugar, cinnamon (if using), baking powder, and salt. Next, add cold cubed butter to the dry ingredients. Using a pastry cutter or your fingers, mix until the mixture resembles coarse crumbs, with some larger bits for added texture. This crumb mixture will create the delicious topping for your Strawberry Rhubarb Crumb Bars.
Step 4: Assemble the Bars
Take about two-thirds of the crumb mixture and press it firmly into the bottom of the prepared baking dish, creating an even crust. Make sure it’s packed down well to hold the filling. Then, carefully spread the fruit filling evenly over this layer, ensuring that the strawberries and rhubarb are well distributed for that perfect bite in every square.
Step 5: Top and Bake
Sprinkle the remaining crumb mixture generously over the fruit layer, covering it evenly. Place the baking dish in the preheated oven and bake for 40-45 minutes. Keep an eye out for a golden-brown topping and bubbling filling, which indicates that your Strawberry Rhubarb Crumb Bars are nearing perfection.
Step 6: Cool and Cut
Once baked, remove the dish from the oven and set it aside to cool completely, which may take about 1-2 hours. Allowing the bars to cool helps them set properly, making them easier to cut into neat squares. Once cool, slice into squares, reveling in the delicious layers of crumb and fruit.
