How to Make Rhubarb Crumb Bars
Creating Rhubarb Crumb Bars involves a two-step process: preparing the rhubarb filling and making the crumb topping. Hereās a detailed breakdown of the ingredients and directions to get you started.
Ingredients:
- 1 lb rhubarb
- 1/2 cup granulated sugar
- 1/4 cup water
- 1 Tbsp lemon juice
- 1/2 tsp vanilla extract
- 1 1/2 cups all-purpose flour
- 1 1/2 cups old-fashioned rolled oats
- 1 cup brown sugar
- 1/2 tsp baking soda
- 1/2 tsp salt
- 1 tsp ground cardamom (you can substitute cinnamon)
- 3/4 cups unsalted butter, cut in pieces (this is 1 1/2 sticks)
Directions:
- Set oven to 350F.
- Rinse and trim the ends off the rhubarb stalks. Slice them into 1-inch pieces and place them in a heavy pot. Toss with the sugar, lemon juice, and water. Stirring constantly, bring the mixture to a boil and cook until the rhubarb has broken down and the mixture is thick (about 20 minutes). If it gets too thick, add a bit more water. You can puree it for a smoother texture if desired. Stir in the vanilla and set aside to cool.
- To make the crust, put the dry ingredients in a food processor and pulse to combine. Add in the butter and pulse until the mixture has a texture of coarse crumbs.
- Reserve 1 1/2 cups of the mixture and press the rest into a buttered 9×13 baking pan, leveling it out.
- Spread the rhubarb filling evenly over the crust, and crumble the reserved dough over the filling.
- Bake for 30 minutes until golden.
- Cool before cutting.
How to Serve Rhubarb Crumb Bars

How to Store Rhubarb Crumb Bars
To store Rhubarb Crumb Bars, allow them to cool completely, then cover them tightly with plastic wrap or transfer them to an airtight container. They can be stored at room temperature for up to 3 days or in the refrigerator for up to a week. For longer storage, freeze them for up to three months, separating layers with parchment paper for easy access.
