Questions I Often Get Asked About This Recipe

1. Can I use frozen rhubarb and strawberries?
Yes! If fresh rhubarb and strawberries aren’t available, frozen ones work well. Just be sure to thaw them and drain excess liquid before using.

2. Can I make these bars gluten-free?
Absolutely! Substitute the all-purpose flour with a gluten-free flour blend, and ensure your oats are certified gluten-free.

3. How should I store the leftovers?
Store the bars in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate them for up to a week.

4. Can I freeze these bars?
Yes! Wrap them individually in plastic wrap and place them in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge before enjoying.

5. What can I substitute for rhubarb?
If you’re not a fan of rhubarb, try using an equal amount of another tart fruit, like raspberries or blackberries, for a different but equally delicious experience.

What You Need to Make Strawberry Rhubarb Crumble Bars

Ingredients:

2 cups diced rhubarb

2 cups diced strawberries

1 cup granulated sugar

3 tablespoons cornstarch

2 cups all-purpose flour

1 1/2 cups old-fashioned oats

1 cup brown sugar, packed

1 teaspoon baking powder

1/4 teaspoon salt

1 cup unsalted butter, melted

Equipment:

9×13-inch baking dish

Parchment paper

Mixing bowls

Whisk and spatula

How to Make Strawberry Rhubarb Crumble Bars

Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line your baking dish with parchment paper for easy removal.

Prepare the Filling: In a large bowl, combine diced rhubarb, strawberries, granulated sugar, and cornstarch. Stir until well coated and set aside.

Make the Crumble: In another bowl, mix the flour, oats, brown sugar, baking powder, and salt. Pour in the melted butter and mix until the ingredients resemble a crumbly texture.

Assemble the Bars: Press half of the crumble mixture evenly into the prepared baking dish to form the base. Spoon the fruit filling over the crust, then sprinkle the remaining crumble on top.

Bake: Place in the oven and bake for 40-45 minutes or until the top is golden brown and the fruit filling is bubbling.

Cool and Slice: Let the bars cool completely in the pan before slicing. This step is crucial for neat, easy-to-serve squares.

Tips for Making the Best Strawberry Rhubarb Crumble Bars

Use Cold Butter for the Crumble: If you prefer a crumblier texture, use cold cubed butter instead of melted, cutting it in with a pastry cutter.

Prevent Sogginess: To avoid a soggy base, make sure to drain excess liquid from your fruit mixture if using frozen fruit.

Add a Flavor Boost: A pinch of cinnamon or a splash of vanilla extract in the crumble can add an extra layer of flavor.

Serving Suggestions: These bars are divine on their own, but a scoop of vanilla ice cream or a dollop of whipped cream takes them to the next level.
