Rhubarb Crumb Bars

There’s something incredibly comforting about a homemade dessert, especially when it involves seasonal ingredients like rhubarb. Rhubarb crumb bars are not just a treat; they capture the essence of home cooking, bringing warmth and sweetness to any gathering. This recipe is so easy to follow, making it perfect for both seasoned bakers and newcomers alike. Imagine biting into a soft, crumbly bar that combines tart rhubarb and a sweet, buttery topping—it’s pure bliss on a plate.

At the heart of these crumb bars are fresh rhubarb, sugar, and a blend of simple pantry staples. The tartness of 2 cups of diced rhubarb pairs beautifully with 1 cup of granulated sugar, while a tablespoon of cornstarch helps thicken the filling just right. A hint of vanilla extract provides warmth, making each bite even more delightful. The crumbly topping is crafted from 2 cups of all-purpose flour, 1 cup of rolled oats, 1/2 cup of packed brown sugar, and just enough baking powder and baking soda for the perfect rise. It’s all bound together with 1 cup of melted unsalted butter, offering a richness that balances the tartness of the rhubarb perfectly.

This recipe is remarkably straightforward. You begin by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking dish. Next, you mix the rhubarb with sugar, cornstarch, and vanilla, then prepare the crumb mixture using flour, oats, brown sugar, and butter. After pressing half of it into the dish, you layer on the rhubarb mixture and finish with more crumbs on top. A simple bake and some cooling time yield a dessert that is easy to serve and share.

These rhubarb crumb bars are versatile, making them a great option for any occasion. Whether you need a sweet pick-me-up on a chilly evening or something special to bring to a potluck, this recipe fits the bill beautifully. You’ll find they are perfect to enjoy with a cup of tea or coffee, bringing a touch of sweetness to your day.

Main Ingredient Tips

When selecting rhubarb for your crumb bars, aim for fresh, vibrant stalks. Look for rhubarb that is firm and free from blemishes. The color can vary from light pink to deep red; just choose those that are crisp. Avoid any stalks that seem limp or have a wilted appearance as they may lack the bright flavor you want. Always wash and trim the ends before dicing, as this helps preserve the taste. Fresh rhubarb is the key to achieving that delightful tartness that contrasts beautifully with the sweetness in this recipe.

Options for Substitutions

  • Granulated Sugar: Use coconut sugar for a lower glycemic index alternative.
  • Brown Sugar: Adjust with a mix of white sugar and maple syrup for a different flavor profile.
  • All-Purpose Flour: Substitute whole wheat flour for a healthier option with more fiber.
  • Unsalted Butter: You can use coconut oil for a dairy-free version.
  • Rolled Oats: Quick oats can be used, but they will change the texture slightly.
  • Cornstarch: Arrowroot powder is an excellent substitute for thickening.

Watch Out for These Mistakes

When preparing rhubarb crumb bars, it’s important to avoid overcooking. The bars should be golden brown on top, which indicates they are done, but keep an eye on them, as baking times can vary. Additionally, ensure that you do not mix your rhubarb with sugar too far in advance to prevent it from becoming too watery. Properly measuring your dry ingredients is crucial; too much flour can lead to a dry topping. Lastly, be sure to allow the bars to cool completely before cutting. This prevents them from falling apart and helps maintain their structure.

What to Serve With Rhubarb Crumb Bars?

Rhubarb crumb bars pair wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream, providing a creamy contrast to the tartness. For a more refreshing touch, serve them with fresh berries like strawberries or blueberries. A cup of hot tea or coffee also complements these sweet treats perfectly, making for a delightful afternoon or evening snack.

Storage Instructions

Store: Keep the bars in the refrigerator for up to 5 days in an airtight container.

Freeze: These rhubarb crumb bars can be frozen for up to 3 months. Just ensure they are well-wrapped to prevent freezer burn.

Reheat: For stovetop reheating, place a bar in a skillet on low heat until warmed through. In the microwave, heat for 15-20 seconds, watching to ensure they don’t become too hot.
