Ingredients You’ll Need

- For the Crust:
- 1 ¾ cups all-purpose flour – This is the base of your crust, giving it the structure needed to hold everything together.
- ½ cup granulated sugar – Sweetens the crust and balances out the tart filling.
- ½ cup unsalted butter, softened – Adds richness and moisture to your crust, creating a tender texture.
- 1 large egg – Acts as a binding agent, helping the crust hold its shape while baking.
- For the Filling:
- 3 cups rhubarb, chopped – The star ingredient; fresh, vibrant rhubarb gives the bars their tartness.
- 1 cup granulated sugar – Balances the tartness of the rhubarb, enhancing the overall flavor of the filling.
- 2 tablespoons cornstarch – Helps thicken the filling and provides a nice sheen.
- 1 teaspoon vanilla extract – Adds depth to the flavor profile, making the filling more complex.
- ½ teaspoon salt – Enhances the sweetness and balances the flavors.
How to Make
Follow these steps to create your Old Fashioned Rhubarb Bars:
- Preheat the oven: Begin by preheating your oven to 350°F (175°C). This ensures an even bake right from the start, giving your crust that perfect golden-brown finish.
- Prepare the crust: In a large mixing bowl, combine the flour and sugar. Then, cut in the softened butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Add in the egg and mix until just combined.
- Press the mixture: Grease a 9×13-inch baking dish, then press two-thirds of the crust mixture into the bottom of the dish evenly. Use your fingers or the bottom of a glass to compact it well. This will form a solid base for your bars.
- Make the filling: In another bowl, combine the chopped rhubarb, sugar, cornstarch, vanilla extract, and salt. Stir until the rhubarb is well coated, allowing the sugar to begin drawing out the juices from the rhubarb.
- Assemble the bars: Pour the filling over the crust in the baking dish. Crumble the remaining one-third of the crust mixture over the top of the rhubarb filling for a nice texture contrast.
- Bake: Place the baking dish in the oven and bake for 40-45 minutes or until the filling bubbles and the topping is lightly golden. The delightful aroma will fill your kitchen—be ready to indulge!
- Cool and serve: Once baked, allow the bars to cool completely in the pan before slicing into squares. This will make for cleaner cuts and help the filling set. Serve at room temperature or chilled.
Variations & Substitutions
Strawberry Rhubarb Bars: Substitute half of the rhubarb with ripe strawberries for a sweeter take on the classic recipe. The added strawberries introduce a lovely sweetness and a touch of color, making the dessert even more appealing.
Gluten-Free Version: Use a gluten-free flour blend instead of all-purpose flour in your crust. Most blends work well and will provide a similar texture without sacrificing flavor. Always check for certified gluten-free labels if necessary.
Vegan Rhubarb Bars: Replace the egg in the crust with 1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water (let it sit for 5 minutes to thicken). Substitute the butter with coconut oil or vegan butter for a delicious dairy-free version.
Nutty Crust Variation: Add ½ cup of chopped walnuts or pecans to the crust mixture for a delightful crunch that complements the soft filling. This adds a new texture and an earthy flavor that pairs beautifully with the rhubarb.
Common Mistakes to Avoid
One common mistake is not using fresh rhubarb. Fresh rhubarb provides essential flavor and texture. Frozen rhubarb can release excess moisture, leading to a soggy base. If using frozen, be sure to thoroughly drain it before adding to your filling.
Another issue is overbaking the bars. While you want the filling to bubble, overbaking can harden the crust and make it dry. Keep an eye on your bars in the final minutes of baking. They should be gently golden and the filling should be visibly bubbly but not overly set.
Lastly, allowing the bars to cool in the pan is crucial. If you try to slice too soon, the filling may ooze out, ruining those perfect squares. Patience is key—letting them set will yield beautifully presented bars.
Storage, Freezing & Reheating Tips
Old Fashioned Rhubarb Bars can be stored in an airtight container in the refrigerator for up to one week. This keeps them fresh and allows the flavors to meld even more. Make sure to line the container with parchment paper to avoid sticking.
If you decide to freeze these bars, slice them first and place parchment paper between layers in an airtight container. They can be frozen for up to three months. To defrost, simply move them to the refrigerator the night before serving.
For reheating, warm individual bars in the microwave for 10-15 seconds or enjoy them cold, as many find that the flavors deepen after a day in the fridge.
Frequently Asked Questions
Can I use rhubarb that’s been frozen? Yes, but make sure to thaw it completely and drain any excess water before using it in the recipe. This will help avoid a soggy crust.
What can I serve with rhubarb bars? A scoop of vanilla ice cream or a dollop of whipped cream pairs wonderfully with the tartness of the rhubarb. A light sprinkle of powdered sugar on top also enhances the presentation.
How can I tell if my rhubarb is fresh? Look for firm, brightly colored stalks. If the rhubarb has brown spots or wilting leaves, it is past its prime. Choosing the freshest rhubarb will ensure the best flavor and texture in your bars.
Can I substitute other fruits for rhubarb? Yes, you can use other tart fruits like blackberries or sour cherries. Adjust the sugar in the filling accordingly to account for different sweetness levels.
What makes the crust crumbly? The key to a crumbly crust lies in how you mix the butter into the flour and sugar. Using cold butter helps create small pockets of fat that melt during baking, resulting in a flaky, crumbly texture.
Conclusion: Old Fashioned Rhubarb Bars offer a nostalgic dessert experience that’s sure to brighten any gathering.
