Step-by-Step Preparation Method

Step 1: Prepare the Baking Dish

Preheat the oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, leaving an overhang on the sides for easy removal after baking.

Step 2: Make the Crumble Mixture

In a large bowl, whisk together the flour, oats, brown sugar, salt, and baking powder. Add the melted butter and vanilla extract, then stir until a moist, crumbly mixture forms.

Step 3: Press the Crust

Reserve 1½ cups of the crumble mixture for the topping. Press the remaining mixture firmly into the prepared baking dish to create an even crust.

Step 4: Prepare the Filling

In another bowl, gently combine the strawberries, rhubarb, granulated sugar, cornstarch, lemon juice, and vanilla extract until the fruit is evenly coated.

Step 5: Assemble the Bars

Spread the fruit filling evenly over the crust, then sprinkle the reserved crumble mixture over the top.

Step 6: Bake

Bake for 45–50 minutes, or until the filling is bubbling and the topping is golden brown. If needed, loosely cover with foil during the last 10 minutes to prevent over-browning. Let the bars cool completely.

Step 7: Chill and Serve

Refrigerate for at least 1 hour to help the bars set. Lift them out using the parchment paper, slice into squares, and serve chilled or at room temperature.
