Ingredients

For the Crust and Crumble Topping

• 2 cups all-purpose flour
• 1 cup old-fashioned rolled oats
• 1 cup brown sugar
• ½ teaspoon salt
• 1 teaspoon baking powder
• 1 cup unsalted butter, melted
• 1 teaspoon vanilla extract

For the Strawberry Rhubarb Filling

• 2 cups fresh strawberries, diced
• 2 cups fresh rhubarb, chopped
• ¾ cup granulated sugar
• 3 tablespoons corn-starch
• 1 tablespoon lemon juice
• 1 teaspoon vanilla extract

Step-by-Step Preparation Method

Step 1:

Preheat your oven to 350°F (175°C) and line a 9×13-inch baking dish with parchment paper, leaving some overhang on the sides. This will make it much easier to lift the bars out of the pan once they have cooled and are ready to slice.

Step 2:

In a large mixing bowl, whisk together the flour, oats, brown sugar, salt, and baking powder until evenly combined. Pour in the melted butter and vanilla extract, then stir with a spoon or pastry cutter until the mixture forms moist, crumbly crumbs with no dry patches remaining.

Step 3:

Measure out and reserve about 1½ cups of the crumb mixture for the topping. Transfer the remaining crumbs to the prepared baking dish and press them firmly into an even layer using the back of a measuring cup or your hands. Make sure the crust is compact so it holds together after baking.

Step 4:

In a separate bowl, combine the chopped strawberries, rhubarb, granulated sugar, cornstarch, lemon juice, and vanilla extract. Gently stir until the fruit is evenly coated and the cornstarch has dissolved into the mixture. The cornstarch will help thicken the juices as the bars bake.

Step 5:

Spread the fruit filling evenly over the prepared crust, making sure the strawberries and rhubarb are distributed in a single layer. Sprinkle the reserved crumb mixture evenly over the top, covering most of the fruit while allowing a few spots of filling to peek through.

Step 6:

Bake for 45–50 minutes, or until the fruit filling is bubbling around the edges and the crumb topping is golden brown. If the top begins to brown too quickly, loosely cover the pan with foil during the last 10 minutes of baking. Remove from the oven and allow the bars to cool completely on a wire rack.

Step 7:

Once cooled, refrigerate the bars for at least 1 hour to help them set and make slicing easier. Use the parchment paper overhang to lift the bars out of the pan, then cut into squares or rectangles before serving. Enjoy them chilled or at room temperature.
