How to Make Strawberry Rhubarb Bars
-
Preheat your oven to 375°F. Line a 9×13” baking pan with foil or parchment and give it a light spray with non-stick cooking spray to prevent sticking.
-
Combine the flour, sugar, and salt in a food processor for the crust. Pulse them together until well mixed, ensuring a sweet and salty base for your bars.
-
Add the butter piece by piece with the processor running. Continue processing until the mixture resembles damp sand, which means you’re getting close to that buttery goodness!
-
Incorporate the beaten egg into the mixture. Process just until combined; it should form a soft dough that holds together nicely.
-
Press half of the dough evenly into the bottom of your prepared baking pan. Make sure it’s level so you have a sturdy foundation for the filling!
-
Mix the chopped rhubarb, strawberries, sugar, and cornstarch in a large bowl. Stir until the fruit is well-coated; this mixture will burst with flavor!
-
Spread the fruit mixture evenly over the crust. Let those vibrant colors shine through before adding the crumb topping.
-
Crumble the remaining dough on top of the fruit mixture. This creates a delicious crunchy topping that will contrast beautifully with the gooey filling underneath.
-
Bake for 45-50 minutes, or until the topping turns golden brown and the fruit filling bubbles. Watch for that enticing aroma that fills your kitchen!
-
Cool completely before lifting the bars out using the foil sling. Slice them into squares and admire your delicious creation!
-
Store at room temperature, loosely covered, for up to 3 days (if they last that long!).
Optional: Drizzle with a bit of icing for a sweet finishing touch.

Expert Tips for Strawberry Rhubarb Bars
• Choose Fresh Produce: Use ripe, fresh strawberries and firm rhubarb for the best flavor in your bars. Overripe fruit can lead to a mushy texture.
• Perfect Dough Consistency: Ensure your butter is softened but not melted when mixing for a crumbly texture. Overmixing will yield a tough crust instead of the desired crumble.
• Check for Doneness: Look for a golden-brown topping and bubbling fruit filling—this indicates your strawberry rhubarb bars are perfectly baked and ready for slicing.
• Cooling is Key: Allow the bars to cool completely before cutting. This helps the filling set and ensures clean, beautiful slices.
• Serving Suggestions: Serve warm with vanilla ice cream or a dollop of whipped cream for an extra delightful treat that enhances the flavors beautifully!
How to Store and Freeze Strawberry Rhubarb Bars
Room Temperature: Store tightly covered or loosely wrapped at room temperature for up to 3 days to maintain freshness and flavor.
Fridge: If you want to extend their life, place the bars in an airtight container in the fridge for up to a week. Just remember to let them come to room temperature before enjoying!
Freezer: For longer storage, individually wrap each bar in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to 2 months.
Reheating: When ready to enjoy from the fridge or freezer, reheat in the oven at 350°F for about 10 minutes until warmed through, or enjoy them cold for a refreshing twist!
Strawberry Rhubarb Bars Recipe FAQs
How do I choose the right rhubarb and strawberries?
Absolutely! Look for rhubarb stalks that are crisp and firm, with a vibrant pinkish-red color. Avoid any that have dark spots all over, indicating potential spoilage. For strawberries, opt for bright red, shiny berries that are slightly fragrant. They should have a slight give when pressed, signaling ripeness.
What is the best way to store leftover bars?
Very! Store your strawberry rhubarb bars at room temperature, loosely covered, for up to 3 days. If you’re expecting them to last longer, place them in an airtight container in the fridge for up to a week. Just remember that they taste best when they’re allowed to come back to room temperature before enjoying!
Can I freeze strawberry rhubarb bars? How?
Definitely! To freeze, individually wrap each bar in plastic wrap and place them in a freezer-safe bag or container. They can be frozen for up to 2 months. When you’re ready to enjoy them, simply remove them from the freezer and let them thaw in the fridge overnight, or reheat in the oven at 350°F for about 10 minutes until warmed through. Perfect for a sweet treat anytime!
What should I do if my crust is too crumbly?
No worries! If your dough seems too crumbly to hold together, it may need just a bit more moisture. Try adding a teaspoon of cold water or milk, one teaspoon at a time, until you’re able to form the dough into a manageable ball. Be careful not to overmix; we want that delightful crumble texture!
Are there any dietary considerations I should know about?
Certainly! This recipe is not inherently gluten-free or dairy-free. However, you can easily substitute all-purpose flour with a gluten-free blend and swap unsalted butter for a dairy-free alternative like coconut oil or vegan butter. Always check the labels, especially for store-bought substitutes, if allergies are a concern!
Can pets eat these bars?
Not at all! While rhubarb and strawberries are safe for humans, rhubarb leaves are toxic to pets, and the sugar content is not advisable for them either. It’s best to keep these delicious strawberry rhubarb bars safely stored away from curious paws!
