Ingredients
  

For the Rhubarb Filling
  • 2 cups fresh rhubarb, chopped (or frozen, thawed and drained) Fresh rhubarb provides the best flavor.
  • 1/4 cup water
  • 1 tablespoon lemon juice
  • 2 tablespoons cornstarch
For the Oat Mixture
  • 1 1/2 cups rolled oats
  • 1 cup all-purpose flour
  • 1 cup light brown sugar
  • 1/2 cup granulated sugar Adjust sweetness to taste.
  • 1/2 cup unsalted butter, softened
  • 1 teaspoon baking soda
  • 1 teaspoon cinnamon
  • 1/4 teaspoon salt

Method
 

Preparation
  1. In a saucepan, combine the chopped rhubarb, water, lemon juice, and cornstarch. Cook over medium heat until the rhubarb is soft and juicy, about 5-7 minutes. Set aside to cool.
Making the Oat Mixture
  1. In a large bowl, mix together the rolled oats, flour, brown sugar, granulated sugar, baking soda, cinnamon, and salt. Add in the softened butter and mix until crumbly.
Assembling the Bars
  1. Preheat your oven to 350°F (175°C). Press half of the oat mixture into the bottom of a greased 9x13 inch baking pan. Spread the cooled rhubarb filling over the top, then sprinkle the remaining oat mixture on top of the rhubarb.
Baking
  1. Bake in the preheated oven for about 30-35 minutes, or until golden brown. Let cool completely before cutting into bars.
Serving
  1. These bars are delightful on their own or can be paired with a scoop of vanilla ice cream or a dollop of whipped cream!

Notes

You can store these bars in an airtight container in the refrigerator for up to a week. They can also be frozen for longer storage. If using frozen rhubarb, ensure it’s fully thawed and drained to avoid excess moisture.
