Ingredients

Dry Ingredients

  • 1 cup Rolled Oats
  • 1 cup All-Purpose Flour
  • 1 cup Brown Sugar packed
  • 1 teaspoon Baking Soda
  • 1 teaspoon Salt

  • 1 cup Unsalted Butter melted

Rhubarb Filling

  • 1 cup Rhubarb chopped
  • ½ cup Granulated Sugar
  • 1 tablespoon Cornstarch
  • 1 tablespoon Lemon Juice
  • 1 teaspoon Vanilla Extract

Instructions

  • Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan.
  • In a large bowl, mix together the rolled oats, all-purpose flour, brown sugar, baking soda, and salt until evenly combined.
  • Pour in the melted butter and stir until the mixture becomes crumbly and well incorporated.
  • Reserve about 1 cup of the oat mixture for the topping. Spread the remaining mixture evenly into the bottom of the prepared baking pan and press down firmly.

  • Spread the rhubarb mixture evenly over the oat crust in the baking pan.
  • Crumble the reserved oat mixture on top of the rhubarb layer.
  • Place the pan in the oven and bake for about 25-30 minutes, or until the topping is golden brown and the filling is bubbling.
  • Allow to cool in the pan before cutting into bars. Enjoy!
