Strawberry Rhubarb Crumb Bars Ingredients
For the Fruit Filling
- Chopped Strawberries – Provides sweetness and moisture; fresh or frozen works well, just drain any liquid from frozen.
- Chopped Rhubarb – Adds a bright tartness; consider reducing sugar for a less sweet option.
- Sugar – Balances the tartness; adjust according to personal preference, especially due to rhubarb’s characteristics.
- Cornstarch – Thickens the filling to prevent it from being too runny; add an extra teaspoon if using juicy strawberries.
- Lemon Juice – Enhances overall flavor; freshly squeezed is best.
For the Crust and Topping
- Flour – Forms the base and crumb topping for structure; all-purpose works well.
- Oats – Adds a hearty texture to the crumb topping, making it more substantial.
- Brown Sugar – Deepens the flavor profile and caramelizes beautifully in the topping.
- Cinnamon – Introduces warmth and enhances flavor; a delightful complement to the fruit.
- Baking Powder – Acts as a leavening agent for a lighter crumb topping.
- Salt – Balances out the sweetness while enhancing the flavors.
- Cold Cubed Butter – Creates a flaky texture in the crumb mixture; chilled butter is key for best results.

Step‑by‑Step Instructions for Strawberry Rhubarb Crumb Bars Recipe
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While it’s heating, grease a 9×13 inch baking dish or line it with parchment paper for easy removal. This step is crucial to ensure your Strawberry Rhubarb Crumb Bars come out perfectly without sticking to the pan, making cleanup a breeze.
Step 2: Mix the Fruit Filling
In a medium bowl, combine your chopped strawberries, rhubarb, sugar, cornstarch, and lemon juice. Gently mix them together to coat the fruit evenly and let the mixture sit for about 10 minutes. This resting period allows the flavors of your filling to meld together beautifully, enhancing the taste of the final bars.
Step 3: Prepare the Crumb Mixture
In a large mixing bowl, whisk together the flour, oats, brown sugar, cinnamon, baking powder, and salt. Use a pastry cutter or your fingers to cut in the cold cubed butter until the mixture resembles coarse crumbs. Aim for a crumbly texture that is slightly sticky, as this will form the delicious topping for your bars.
Step 4: Assemble the Bars
Press approximately two-thirds of the crumb mixture into the base of the prepared baking dish, ensuring an even layer. Pour the fruit filling over the crumb base, spreading it out evenly. Finally, sprinkle the remaining crumb mixture over the top of the fruit filling to create a beautiful and crunchy topping for your Strawberry Rhubarb Crumb Bars.
Step 5: Bake to Perfection
Place the assembled pan in the preheated oven and bake for 40-45 minutes. Keep an eye on the bars as they bake; they should turn golden brown and the fruit filling should bubble up around the edges. This bubbling is a visual cue that your filling is perfectly cooked and ready to enjoy.
Step 6: Cool and Slice
Once baked, remove the pan from the oven and allow the bars to cool completely in the pan. This cooling period ensures that your Strawberry Rhubarb Crumb Bars will set properly, making it easier to slice them into neat squares. After about 1-2 hours of cooling, cut into squares and get ready to savor the delicious sweetness!

Make Ahead Options
These Strawberry Rhubarb Crumb Bars are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the fruit filling and crumb mixture up to 24 hours in advance. Simply mix the strawberries, rhubarb, sugar, cornstarch, and lemon juice, then refrigerate (this enhances the flavors too!). Store the crumb topping mixture in an airtight container to keep it fresh until you’re ready to bake. When you’re set to serve, just press the crumb base into the pan, layer on the fruit mixture, top with the remaining crumb, and bake as directed. Following these prep-in-advance steps means your delicious Strawberry Rhubarb Crumb Bars will be just as delightful as if you made them the same day!
