Ingredients
- 1 cup all-purpose flour
- 1 cup old-fashioned rolled oats
- ½ cup light brown sugar, packed
- ¼ teaspoon baking soda
- ¼ teaspoon salt
- ½ teaspoon ground cinnamon
- ½ cup unsalted butter, melted and slightly cooled
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup fresh strawberries, hulled and chopped
- 1 cup rhubarb stalks, trimmed and chopped
- ⅓ cup granulated sugar
- 1 tablespoon cornstarch
- 1 tablespoon lemon juice
- Optional: powdered sugar for dusting
Instructions
- Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides to help lift the bars out later.
- In a medium bowl, whisk together the flour, oats, brown sugar, baking soda, salt, and cinnamon until evenly combined.
- Pour in the melted butter, then add the egg and vanilla extract. Stir with a spatula until a crumbly dough forms.
- Reserve about 1 cup of this crumb mixture for the topping. Press the remaining dough evenly into the bottom of the prepared pan to form the crust.
- In another bowl, gently toss the chopped strawberries and rhubarb with the granulated sugar, cornstarch, and lemon juice. Let sit for 5 minutes to macerate and thicken slightly.
- Spread the fruit mixture evenly over the crust layer.
- Sprinkle the reserved crumb mixture over the fruit to create a crumbly topping.
- Bake for 40-45 minutes, or until the topping is golden brown and the fruit filling is bubbling around the edges.
- Remove from the oven and let cool completely in the pan on a wire rack—this helps the bars set and makes slicing easier.
- Once cooled, use the parchment paper overhang to lift the bars from the pan. Cut into 12 squares and dust with powdered sugar if desired before serving.
Tips
- Substitution for oats: If your child has oat allergies, you can substitute quick-cooking oats or finely chopped nuts like almonds for a similar texture.
- Rhubarb prep: Use only fresh, firm rhubarb stalks; avoid any that are soft or discolored to ensure the best flavor and texture.
- Storage: Store bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week to keep them fresh longer.
- Common mistake: Don’t skip letting the fruit mixture macerate with sugar and cornstarch; this step thickens the filling and prevents soggy bars.
Serving Suggestions
These strawberry rhubarb bars are delicious on their own or paired with a dollop of whipped cream or a scoop of vanilla ice cream for a more indulgent treat. For a healthier twist, serve with plain Greek yogurt and a drizzle of honey. They also make a great snack for lunchboxes or a sweet addition to afternoon tea or picnics.
Variations
You can easily customize this recipe to suit your family’s tastes. Try adding a handful of chopped nuts like walnuts or pecans to the crumb topping for extra crunch. Substitute half the strawberries with blueberries or raspberries for a mixed berry version. For a gluten-free option, use a certified gluten-free flour blend and oats. If you prefer a less tart filling, increase the sugar slightly or add a tablespoon of honey to the fruit mixture.
Storage and Reheating
Store these bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to 7 days. To freeze, wrap individual bars tightly in plastic wrap and place in a freezer-safe bag for up to 3 months. Thaw overnight in the refrigerator before serving. To reheat, warm bars in a microwave for 15-20 seconds or in a preheated 300°F (150°C) oven for 5-7 minutes to restore softness and flavor.
Frequently Asked Questions
Can I use frozen strawberries and rhubarb for this recipe?
Yes, you can substitute frozen fruit if fresh isn’t available. Thaw and drain excess liquid before using to avoid a watery filling. The texture may be slightly softer but still delicious.
How do I know when the bars are done baking?
The topping should be golden brown and the fruit filling bubbling around the edges. If the center still looks wet, bake for an additional 5-10 minutes, checking frequently to avoid overbaking.
Can I make these bars vegan?
Yes, replace the butter with a vegan margarine or coconut oil and use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) instead of a chicken egg. The texture may be slightly different but still tasty.
What is the best way to cut the bars without crumbling?
Allow the bars to cool completely before cutting. Use a sharp knife and wipe it clean between cuts for neat slices. Chilling the bars in the fridge for 30 minutes before slicing can also help them hold together better.
Can I reduce the sugar in the fruit filling?
Yes, you can reduce the granulated sugar to ¼ cup if you prefer a less sweet bar, but keep in mind that sugar helps thicken the filling and balance rhubarb’s tartness.
Are these bars suitable for toddlers?
These bars are generally safe for toddlers, but be mindful of choking hazards from oats or nuts if added. Cut into small, manageable pieces and supervise young children while eating.
This kid friendly strawberry rhubarb bars recipe is a perfect introduction to seasonal fruits with a fun texture and balanced flavors. Whether for a snack, dessert, or lunchbox treat, these bars are sure to become a family favorite.
