Ingredients
1 ½ cups all purpose flour
½ teaspoon baking soda
½ teaspoon kosher salt
1 ½ cups old fashioned rolled oats (not quick or steel cut)
¾ cup packed brown sugar
½ cup granulated sugar
¾ cup cold unsalted butter, cut into small cubes
1 teaspoon vanilla extract
2 cups fresh strawberries, diced
2 cups fresh or frozen rhubarb, diced (if frozen, thaw and drain first)
1 tablespoon fresh lemon juice
½ cup granulated sugar
2 tablespoons cornstarch
Instructions
1-Preheat Oven and Prepare Pan: Preheat oven to 350°F. Butter a 9×9-inch baking dish and line with parchment paper.
2-Make the Crumb Layer: Whisk flour, baking soda, and salt; add oats, brown sugar, and granulated sugar. Stir in melted butter and vanilla until the mixture resembles coarse crumbs.
3-Press the Base: Press about two-thirds of the crumb mixture firmly into the prepared pan to form the bottom crust.
4-Make the Fruit Filling: Toss diced strawberries and rhubarb with lemon juice. Whisk sugar and cornstarch, then mix with the fruit until evenly coated.
5-Assemble and Bake: Spread the fruit filling over the base, top with remaining crumbs, and bake for 45-50 minutes until golden and bubbling. Cool completely before slicing.

🥄 Use old fashioned rolled oats for the perfect chewy crumb texture; quick or steel cut oats will not yield the right result.
⏲️ Let the bars cool completely on a wire rack for at least an hour so the filling can set and slicing stays clean.
🍦 Serve with a scoop of vanilla ice cream or a dollop of whipped cream for a classic spring dessert pairing.
