Strawberry rhubarb bars are a deliciously sweet and tangy treat that kids love. Combining the natural tartness of rhubarb with juicy strawberries, these bars offer a perfect balance of flavors in a soft, buttery crust that’s easy for little hands to hold. This recipe is simple enough for family baking sessions and yields a dessert that’s both fun and wholesome.
Ingredients
- 1 cup all-purpose flour
- 1 cup rolled oats
- ½ cup light brown sugar, packed
- ½ teaspoon baking powder
- ¼ teaspoon salt
- ½ cup unsalted butter, melted and slightly cooled
- 1 large egg
- 1 teaspoon vanilla extract
- 1 ½ cups fresh strawberries, hulled and chopped
- 1 ½ cups fresh rhubarb, chopped into small pieces (about ½-inch)
- ¾ cup granulated sugar
- 2 tablespoons cornstarch
- 1 tablespoon lemon juice
- Optional: powdered sugar for dusting
Instructions
- Preheat the oven and prepare the pan: Set your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal later.
- Make the crust: In a large bowl, combine the flour, rolled oats, brown sugar, baking powder, and salt. Stir to mix evenly.
- Add wet ingredients: Pour in the melted butter, egg, and vanilla extract. Mix until the dough comes together and is slightly crumbly but holds when pressed.
- Press the crust: Reserve about 1 cup of this dough for the topping. Press the remaining dough evenly into the bottom of the prepared pan, creating a firm base.
- Prepare the filling: In a medium bowl, mix the chopped strawberries, rhubarb, granulated sugar, cornstarch, and lemon juice. Toss gently to coat all the fruit evenly.
- Assemble the bars: Spread the fruit mixture evenly over the crust layer in the pan.
- Add the topping: Crumble the reserved dough over the fruit filling, covering it as much as possible but leaving some gaps for the fruit to peek through.
- Bake: Place the pan in the oven and bake for 40 to 45 minutes, or until the topping is golden brown and the fruit filling is bubbly.
- Cool and serve: Allow the bars to cool completely in the pan on a wire rack. Use the parchment paper overhang to lift the bars out, then cut into squares. Dust with powdered sugar if desired before serving.
Tips
- Rhubarb substitute: If rhubarb is unavailable, green apples or tart cherries can provide a similar tangy contrast with strawberries.
- Sweetness adjustment: Depending on your kids’ taste, you can reduce the sugar in the filling by ¼ cup or add a splash of honey for a natural sweetener alternative.
- Storage: Keep bars stored in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days to maintain freshness.
- Common mistake: Avoid chopping the rhubarb pieces too large; small, uniform pieces ensure even cooking and prevent overly fibrous bites.
Serving Suggestions
These strawberry rhubarb bars are perfect as a snack or a light dessert. Serve them slightly chilled or at room temperature. For a kid-friendly twist, offer with a dollop of whipped cream or a scoop of vanilla ice cream. They also pair nicely with a glass of cold milk or a mild herbal tea for grown-ups.
Variations
To change up this classic recipe, try adding a handful of chopped nuts like walnuts or pecans to the topping for extra crunch. You can also swap rolled oats for quick oats if you prefer a softer texture. For a gluten-free version, use a 1:1 gluten-free baking flour blend and certified gluten-free oats. Another fun variation is to sprinkle cinnamon or nutmeg into the crust or filling to add warmth and spice.
Storage and Reheating
Store leftover strawberry rhubarb bars in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days; this helps keep the fruit fresh and the crust from becoming soggy. To freeze, wrap individual bars tightly in plastic wrap and place in a freezer bag for up to 3 months. Thaw overnight in the fridge before serving.
Reheat bars gently in a microwave for 15-20 seconds or in a preheated 325°F (160°C) oven for 10 minutes until warmed through. Avoid overheating to prevent drying out the bars.
Frequently Asked Questions
Can I use frozen strawberries and rhubarb?
Yes, but drain them well to remove excess moisture before using. Frozen fruit releases more liquid, which can make the bars soggy if not properly drained.
How do I know when the bars are done baking?
The topping should be golden brown, and you’ll see the fruit filling bubbling around the edges. If the topping browns too quickly, cover loosely with foil and continue baking until the filling bubbles.
Can I make these bars vegan?
Yes, substitute the butter with a plant-based margarine and replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, set for 5 minutes). The texture may be slightly different but still delicious.
Is it safe for kids to eat rhubarb raw?
Raw rhubarb leaves are toxic, but the stalks used in this recipe are safe when cooked. Always discard the leaves and use only the stalks.
Can I double this recipe for a larger batch?
Absolutely. Use a 9×13-inch pan and increase the baking time to about 50-55 minutes, checking for doneness as described above.
What’s the best way to cut the bars for kids?
Once cooled, cut into small, manageable squares about 2 inches wide. This size is perfect for little hands and helps control portion sizes.
