Ingredients You’ll Need
The magic of these Strawberry Rhubarb Bars lies in their simple, wholesome ingredients that come together to create that irresistible texture and flavor combination. Each ingredient has a role, from the hearty oats giving a nutty crunch to the tangy rhubarb that brightens up the sweetness of the strawberries.
- 1 1/2 cups all-purpose flour: Provides the base structure for the crust and topping, ensuring a tender bite.
- 1 1/2 cups rolled oats: Adds texture and a wholesome chewiness that complements the fruit filling.
- 1 cup brown sugar, packed: Imparts a rich, caramel-like sweetness to balance the tartness of the rhubarb.
- 1 teaspoon baking powder: Helps create a delicate lift in the crumbly crust and topping.
- 1/2 teaspoon salt: Enhances all the flavors, rounding out the sweetness and fruitiness perfectly.

- 1/2 cup granulated sugar: Sweetens the fruit filling just enough to highlight natural flavors.
- 1 tablespoon cornstarch: Thickens the strawberry-rhubarb filling so it stays perfectly set.

- 1 teaspoon vanilla extract: Provides a subtle warmth and depth to the filling’s flavor profile.
How to Make Strawberry Rhubarb Bars Recipe
Step 1: Preheat Oven
Begin by warming your oven to 350°F (175°C). This is the perfect temperature to achieve that golden crust and bubbly filling that make these bars irresistible. Also, line a 9×13-inch baking dish with parchment paper to ensure easy removal and clean-up afterward.
Step 2: Prepare the Crust and Topping
In a large bowl, mix together the flour, rolled oats, brown sugar, baking powder, and salt. Stir in the melted butter until you have a crumbly mixture that almost resembles coarse sand. Press about two-thirds of this crumbly mixture firmly into the bottom of your prepared pan to create an even crust layer. Reserve the remaining one-third of the mixture for the topping—this two-part layer adds a delightful crunch to the finished bars.
Step 3: Prepare the Filling
In a separate bowl, combine the diced strawberries and rhubarb, granulated sugar, cornstarch, lemon juice, and vanilla extract. Toss everything carefully to ensure the fruit is well coated. The cornstarch works its magic here by thickening the mixture as it bakes, so your filling won’t be runny but perfectly luscious and set.
Step 4: Assemble the Bars
Spread the beautifully coated fruit filling evenly over your crust layer in the baking dish. Then, sprinkle the reserved oat crumb mixture on top. This layered approach ensures every bite has a harmonious blend of buttery crust, tart-sweet fruit, and crumbly topping.
Step 5: Bake
Bake in your preheated oven for 40 to 45 minutes until the topping is golden brown and the fruit filling is bubbly and fragrant. Once baked, let the bars cool completely in the pan—this resting time allows the filling to set properly so the bars slice cleanly.
How to Serve Strawberry Rhubarb Bars Recipe
Garnishes
For a finishing touch, sprinkle the bars with a light dusting of powdered sugar, or add a dollop of freshly whipped cream. A few extra fresh strawberry slices on the side bring elegant color and a fresh burst of flavor that complements the bars beautifully.
Side Dishes
These bars shine as a standalone dessert, but they also pair beautifully with a scoop of vanilla ice cream or a simple serving of Greek yogurt. For a brunch spread, bring out some fresh fruit and a warm cup of coffee or tea to create a balanced and inviting plate.
Creative Ways to Present
You can cut these bars into small bite-sized squares for easy party finger food, or serve them on decorative plates with edible flowers for a sophisticated look. Another fun idea is layering crumbled bars over vanilla pudding cups for a parfait-style dessert.
Make Ahead and Storage
Storing Leftovers
Once cooled, store your leftover Strawberry Rhubarb Bars in an airtight container in the refrigerator. They will stay fresh and delicious for 3-4 days, making them perfect for enjoying over a few days without losing that delightful texture.
Freezing
If you want to keep these bars longer, they freeze wonderfully. Wrap individual bars or the whole batch tightly in plastic wrap and a layer of foil, then freeze for up to 2 months. Thaw overnight in the fridge before serving to maintain the best texture.
Reheating
To enjoy warm bars, gently reheat them in a 300°F oven for about 10 minutes or until just warm. This helps to bring back the gooey fruit filling and toasts the crumb topping slightly, making every bite cozy and comforting.
FAQs
Can I use frozen strawberries and rhubarb for this recipe?
Absolutely! Just make sure to thaw and drain any excess liquid from the frozen fruit before mixing to prevent the bars from becoming too soggy.
Is there a way to make these bars gluten-free?
Yes, you can substitute the all-purpose flour with a gluten-free flour blend suitable for baking. Ensure your oats are certified gluten-free as well to keep the bars fully gluten-free.
Can I substitute the butter with a plant-based alternative?
Yes, melted coconut oil or vegan butter works well and gives a nice rich flavor—perfect if you’re avoiding dairy.
How do I know when the bars are done baking?
Look for a golden-brown topping and bubbly fruit filling around the edges. The aroma of baked fruit and toasted oats is also a great indicator that they are perfectly baked.
Can I add other fruits to the filling?
Definitely! Blackberries, blueberries, or even diced apples pair nicely with rhubarb and strawberries, giving a fresh twist to the bars.

Filling
- 2 cups fresh strawberries, diced

- 1/2 cup granulated sugar
- 1 tablespoon cornstarch
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper to prevent sticking and for easy removal of the bars.
- Prepare the Crust and Topping: In a large bowl, combine the all-purpose flour, rolled oats, brown sugar, baking powder, and salt. Stir in the melted unsalted butter until the mixture becomes crumbly. Press about two-thirds of this oat mixture firmly into the bottom of the prepared baking dish to form an even crust. Set aside the remaining oat mixture to use later as the topping.

- Assemble the Bars: Evenly spread the fruit filling over the prepared oat crust in the baking dish. Then sprinkle the reserved oat crumb mixture evenly over the fruit layer, creating a crumbly topping.
- Bake: Place the baking dish in the preheated oven and bake for 40 to 45 minutes, or until the oat topping is golden brown and the fruit filling is bubbly. This ensures the filling is fully cooked and the bars hold together well.
- Cool and Serve: Remove the bars from the oven and allow them to cool completely in the baking dish. Once cooled, lift out the parchment paper to remove the entire slab and cut into 16 squares. Serve and enjoy!
Notes
- Make sure to fully cool the bars before cutting to prevent the filling from leaking out.
- For extra flavor, you can add a pinch of cinnamon or nutmeg to the crust mixture.
- Fresh fruit works best, but you can substitute frozen strawberries and rhubarb—just thaw and drain excess moisture before mixing.
- Store bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
- To make cutting easier, chill the bars in the refrigerator for 30 minutes before slicing.
