Tools Needed, Serving Size, and Time Commitment

- 9×9-inch baking pan
- Mixing bowls (1 large, 1 medium)
- Pastry cutter or fork
- Measuring cups and spoons
- Spatula or wooden spoon
- Wire rack for cooling
- Knife for slicing
Servings:
- Makes approximately 9 to 12 bars, depending on how you slice them
Prep and Bake Time:
- Preparation time: 20 minutes
- Baking time: 45–50 minutes
- Cooling time: 1 hour (recommended before slicing)
- Total time: About 2 hours, including cooling
Ingredients
For the Crust and Crumble:
- 1 1/2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, cold and cubed
For the Filling:
- 2 cups diced rhubarb (fresh or thawed from frozen)
- 2 cups diced strawberries
- 1/2 cup granulated sugar
- 2 tablespoons cornstarch
- 1 tablespoon lemon juice (freshly squeezed)
Step-by-Step Instructions
Step 1: Preheat the Oven and Prepare Your Pan
Start by preheating your oven to 350°F (175°C). Grease a 9×9-inch baking pan with non-stick spray or line it with parchment paper for easier removal later. Set aside.
Step 2: Make the Crust and Crumble
In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt.
Add the cold, cubed butter to the bowl. Using a pastry cutter or fork, cut the butter into the dry ingredients until the mixture resembles coarse crumbs. You want small, pea-sized bits of butter throughout the mix, which helps achieve a tender, crumbly texture.
Reserve 1 cup of the crumb mixture for the topping. Press the remaining mixture firmly into the bottom of the prepared baking pan to create a uniform crust.
Step 3: Prepare the Fruit Filling
In a separate medium bowl, combine the diced rhubarb, diced strawberries, sugar, cornstarch, and lemon juice. Toss the mixture until the fruit is evenly coated and the cornstarch is well distributed. This mixture will thicken as it bakes.
Step 4: Layer the Filling Over the Crust
Spread the fruit mixture evenly over the crust, making sure the fruit is distributed to the edges of the pan. This ensures every bar gets a good balance of strawberry and rhubarb flavor.
Step 5: Add the Crumble Topping
Sprinkle the reserved crumb mixture over the fruit filling. Don’t worry about being too precise—some larger chunks create a lovely texture once baked.
Step 6: Bake
Place the pan in the preheated oven and bake for 45 to 50 minutes, or until the crumble topping is golden brown and the fruit filling is bubbly. The aroma should be sweet and slightly tart with buttery notes.
Step 7: Cool and Slice
Remove the baking dish from the oven and allow it to cool completely on a wire rack. This step is important for the bars to firm up and slice cleanly.
Once fully cooled, cut into squares or rectangles using a sharp knife. Wipe the blade between cuts for neat slices.
Recommendations for Recipe Success
1. Use Cold Butter
The key to a perfect crumble is cold butter. Softened or melted butter won’t create the crumbly texture that makes these bars so satisfying.
2. Don’t Skip the Lemon Juice
Lemon juice adds brightness and enhances both the strawberry and rhubarb flavors. Even just a tablespoon makes a difference.
3. Let the Bars Cool Completely
Cutting too soon will result in a runny filling. For clean, defined layers, allow the bars to cool for at least 1 hour before slicing.
4. Add Texture with Nuts or Oats (Optional)
For extra crunch, you can add 1/4 cup of chopped nuts or rolled oats to the reserved crumb topping.
5. Adjust Sweetness as Needed
If your fruit is particularly tart (especially rhubarb), you can increase the sugar in the filling by a couple of tablespoons.
Serving and Storage Tips
Serving Ideas:
- Serve bars as-is or with a dusting of powdered sugar
- Add a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence
- Perfect as a coffee break treat, picnic dessert, or a summer brunch addition
Storage:
- Room Temperature: Store in an airtight container for up to 2 days
- Refrigerator: Keeps well for up to 5 days—the cooler temperature helps maintain structure
- Freezer: Freeze individual bars wrapped in plastic wrap and placed in a freezer-safe bag or container. They’ll keep for up to 2 months. Thaw in the fridge before serving
Frequently Asked Questions
1. Can I use frozen strawberries and rhubarb?
Yes, but thaw them completely and drain excess liquid before using. This prevents the filling from becoming too watery during baking.
2. What if I don’t have rhubarb?
You can substitute with more strawberries or try other fruits like raspberries or blueberries. The bars may be sweeter, so consider adjusting sugar levels accordingly.
3. Can I make these bars gluten-free?
Absolutely. Use a 1:1 gluten-free flour blend that includes xanthan gum for best results. Make sure all other ingredients are certified gluten-free as well.
4. Why did my bars turn out soggy?
This usually happens if the fruit wasn’t drained properly (if using frozen) or if the bars were sliced before fully cooling. Also, make sure to use enough cornstarch to thicken the filling.
5. Can I double this recipe?
Yes. For a crowd, double the recipe and bake in a 9×13-inch pan. Increase the baking time slightly and keep an eye on the top—it should be golden brown and the filling bubbly.
