Rhubarb bars are a delightful, tangy-sweet dessert that perfectly balances tart rhubarb with a buttery crust and crumbly topping. This easy rhubarb bars recipe is great for beginners because it uses simple ingredients and straightforward steps, delivering a delicious, crowd-pleasing treat every time.
Ingredients
- 2 cups chopped fresh rhubarb (about 1/2-inch pieces)
- 1 1/4 cups granulated sugar, divided
- 2 cups all-purpose flour, divided
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup unsalted butter, softened (2 sticks)
- 1 large egg
- 1 teaspoon vanilla extract
- Optional: 1 tablespoon cornstarch (to thicken filling if rhubarb is very juicy)
Instructions
- Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper or grease it lightly with butter.
- In a medium bowl, toss the chopped rhubarb with 1/2 cup of the sugar (and cornstarch, if using) to macerate and help reduce excess moisture. Set aside.
- In a large bowl, combine 1 1/2 cups of flour, baking powder, salt, and the remaining 3/4 cup sugar.
- Add the softened butter, egg, and vanilla extract to the flour mixture. Using a hand mixer or your fingers, mix until the dough forms coarse crumbs.
- Press about two-thirds of the crumb mixture evenly into the bottom of the prepared baking pan to form the crust.
- Spread the rhubarb mixture evenly over the crust layer.
- Crumble the remaining dough evenly on top of the rhubarb layer to create a crumb topping.
- Bake in the preheated oven for 40-45 minutes, or until the topping is golden brown and the rhubarb filling is bubbling.
- Remove from oven and allow to cool completely in the pan on a wire rack before cutting into bars.
Tips
- Substitutions: If you don’t have fresh rhubarb, frozen rhubarb works well—just thaw and drain excess liquid before use. You can also substitute half the sugar with brown sugar for a deeper flavor.
- Adjusting tartness: Rhubarb can be quite tart. If you prefer sweeter bars, increase the sugar in the filling by up to 1/4 cup, but be careful not to make it too sweet as the balance is key.
- Common mistake: Don’t skip macerating the rhubarb with sugar; this step helps reduce excess moisture and prevents soggy bars.
- Butter temperature: Use softened (not melted) butter to ensure the crumb topping has a nice texture—too soft or melted butter will make it greasy.
Serving Suggestions
Rhubarb bars are best served at room temperature or slightly chilled. For an extra indulgent touch, serve warm bars with a scoop of vanilla ice cream or a dollop of whipped cream. They also pair wonderfully with a cup of tea or coffee for a perfect afternoon snack or dessert.
Variations
To customize your rhubarb bars, try mixing in fresh strawberries or raspberries with the rhubarb for a fruity twist. You can also add 1/2 teaspoon ground cinnamon or nutmeg to the crumb topping for a warm spice note. For a nutty crunch, sprinkle chopped walnuts or almonds over the rhubarb layer before adding the crumb topping.
Storage and Reheating
Store rhubarb bars in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate them for up to 5 days. You can also freeze the bars by wrapping them tightly in plastic wrap and aluminum foil; they keep well up to 3 months. To reheat, warm the bars in a 325°F (160°C) oven for 10-15 minutes or microwave individual pieces for 15-20 seconds until just warm.
Frequently Asked Questions
Can I use frozen rhubarb instead of fresh?
Yes, frozen rhubarb can be used. Thaw it completely and drain any excess liquid before mixing with sugar. This prevents the filling from becoming too watery and helps maintain the right texture.
Do I need to peel rhubarb before using?
No, peeling rhubarb isn’t necessary. The stalks are tender enough when chopped into small pieces. Just make sure to trim off any dry or tough ends.
Why are my rhubarb bars soggy?
Sogginess usually results from excess moisture in the filling. To avoid this, macerate the rhubarb with sugar to draw out liquid, and consider adding a tablespoon of cornstarch to thicken the filling. Also, make sure your bars cool completely before cutting.
Can I make these bars gluten-free?
Absolutely! Substitute the all-purpose flour with a gluten-free flour blend designed for baking. You may need to adjust the amount slightly to get the right crumb texture, but the recipe adapts well.
How do I know when the bars are done?
The bars are ready when the crumb topping turns golden brown and the rhubarb filling is bubbling around the edges. If the center seems undercooked, give it a few more minutes and test with a toothpick for firmness.
Can I prepare the dough ahead of time?
Yes, you can prepare the crumb dough and refrigerate it for up to 24 hours before assembling. This can make the process quicker and allow the flavors to develop slightly. Just bring the dough to room temperature before pressing into the pan.
With its simple steps and approachable ingredients, this easy rhubarb bars recipe is a fantastic way to enjoy the unique tartness of rhubarb in a sweet, crumbly dessert. Whether you’re baking for a family gathering or a casual treat, these bars will quickly become a favorite.
