Ingredients You’ll Need

3 cups all-purpose flour: Form the base for the crumb crust. For gluten-free bars, substitute with a 1:1 gluten-free flour blend.
¼ cup granulated sugar: A hint of sweetness for the crust. Feel free to use coconut sugar if desired.
½ cup packed light or dark brown sugar: Adds moisture and a rich flavor to the crumb mixture.
1 teaspoon baking powder: Helps the crust to rise slightly and create a fluffy texture.
¼ teaspoon salt: Enhances the other flavors in the bars.
1 tablespoon orange or lemon zest: Brightens up the flavors with a citrusy aroma.
1 cup salted butter (cold and cubed): The star of the crumb crust providing richness and texture. Don’t forget to keep it cold for the perfect crumb.
1 large egg (lightly beaten): Binds the crust ingredients together and gives it structure.
3 cups sliced strawberries (chopped in ½-in pieces): The star of the filling–fresh, juicy, and sweet!
2 cups sliced rhubarb (chopped in ½-in pieces): Offers a delightful tartness that complements the strawberries.
½ cup granulated sugar: Sweetens the fruit filling, balancing the tartness of the rhubarb.
4 teaspoons cornstarch: Thickens the filling to prevent it from being runny and helps to bind the fruit together.

How to Make Strawberry Rhubarb Crumb Bars

Preheat Your Oven: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan for easy release.
Make the Crust: In a large mixing bowl, combine 3 cups all-purpose flour, ¼ cup granulated sugar, ½ cup packed brown sugar, 1 teaspoon baking powder, and ¼ teaspoon salt. Mix well. Add the cold, cubed butter and use a pastry cutter or your fingers to blend until it resembles coarse crumbs.
Add Egg and Zest: Stir in 1 tablespoon of orange or lemon zest and 1 lightly beaten egg until just combined. The dough should hold together but still be crumbly.
Prepare the Fruit Filling: In another bowl, mix together 3 cups of sliced strawberries and 2 cups of sliced rhubarb. Add ½ cup granulated sugar and 4 teaspoons of cornstarch, tossing to combine until the fruit is well-coated.
Layer the Ingredients: Press approximately two-thirds of the crumb mixture into the prepared baking pan to form the crust. Spread the fruit mixture evenly on top. Finally, sprinkle the remaining crumb mixture over the fruit layer.
Bake: Place the pan in the preheated oven and bake for about 50-55 minutes or until the edges are golden brown and the filling is bubbling around the edges.
Cool and Serve: Once baked, remove from the oven and let cool completely in the pan on a wire rack. Cut into squares and enjoy your Strawberry Rhubarb Crumb Bars!

Storing & Reheating

Store your Strawberry Rhubarb Crumb Bars in an airtight container at room temperature for up to 2 days. If you want to keep them longer, transfer them to the refrigerator, where they’ll last for about a week. To freeze, wrap the bars tightly in plastic wrap followed by aluminum foil and store for up to 3 months. When you’re ready to enjoy them again, simply thaw at room temperature. Reheat in the oven at 350°F (175°C) for about 5-10 minutes for a refreshing warm treat. Just note that the texture might soften slightly after freezing, but a quick reheat will bring them back to life!

Chef’s Helpful Tips

Avoid over-mixing the dough when adding the egg; it should remain crumbly for a nice texture in the bars.
If your rhubarb is especially tart, adjust the sugar in the fruit filling to suit your taste.
Make sure to let the bars cool completely before cutting into them; this helps them set and makes cleaner slices.
For extra flavor, consider adding some vanilla extract or a sprinkle of cinnamon to the fruit mixture.
These bars can be made ahead of time and stored in the fridge for a quick dessert option when hosting.

Whether you’re making them for a gathering or just for yourself, these Strawberry Rhubarb Crumb Bars are sure to be a hit. Each bite brings a delightful balance of sweet and tart, encapsulating the spirit of summer. Feel free to experiment with different fruits or add a scoop of ice cream on the side for an elevated treat. You’ll find they disappear just as fast as you can make them!

Recipe FAQs

Can I use frozen strawberries or rhubarb for this recipe?

Absolutely! You can use frozen strawberries or rhubarb. Just make sure to thaw and drain any excess liquid before mixing them into the filling to prevent it from becoming too watery.

How do I know when the bars are done baking?

You’ll know your bars are ready when the edges are golden brown and you can see the filling bubbling slightly around the edges. A toothpick inserted into the crumb topping should come out clean.

Can I make these bars ahead of time?

Yes! These bars can be made a day or two in advance. Just store them in the refrigerator, wrapped tightly, to keep them fresh. This also allows the flavors to meld beautifully!

What else can I add to the filling?

Feel free to experiment! Adding a handful of blueberries, blackberries, or even some chopped peaches can give your bars a fun twist, and you can also include spices like cinnamon or ginger for a warm kick.
