Amish Oatmeal Rhubarb Bars are a comforting and tangy treat featuring a buttery oatmeal crust, a sweet and tart rhubarb filling, and a crumbly oat topping. These bars combine the rustic flavors of oatmeal and rhubarb, creating a perfect balance of sweet and sour.

Ingredients

Scale
  • 2 cups rhubarb, diced
  • 1 cup granulated sugar (for rhubarb filling)
  • 1 tablespoon cornstarch
  • 1 tablespoon lemon juice
  • 1 teaspoon vanilla extract
  • 2 cups old-fashioned rolled oats
  • 1 cup all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup brown sugar, packed
  • 1/2 cup unsalted butter, softened
  • 1 large egg
  • 1 teaspoon ground cinnamon
  • 1 teaspoon vanilla extract
  • 1/4 cup milk

Instructions

  1. Preheat the oven to 350°F (175°C). Grease or line an 8×8-inch baking pan with parchment paper.
  2. In a medium saucepan, combine the diced rhubarb, granulated sugar, cornstarch, lemon juice, and vanilla extract. Cook over medium heat, stirring constantly until the rhubarb softens and the mixture thickens, about 5-7 minutes. Remove from heat and set aside to cool slightly.
  3. In a large bowl, combine the rolled oats, flour, baking soda, salt, and ground cinnamon.
  4. In another bowl, cream together the brown sugar, softened butter, egg, vanilla extract, and milk until smooth and well combined.
  5. Add the wet ingredients to the dry ingredients and stir until the mixture becomes crumbly but sticks together when pressed.
  6. Press half of the oatmeal mixture into the prepared baking pan to form an even bottom crust.
  7. Spread the rhubarb filling evenly over the oatmeal crust.
  8. Sprinkle the remaining oatmeal mixture over the rhubarb filling, pressing it lightly to form a crumbly top layer.
  9. Bake for 40-45 minutes or until the top is golden brown and the filling is bubbling.
  10. Let the bars cool completely in the pan before cutting into squares.
  11. Serve and enjoy these delicious Amish Oatmeal Rhubarb Bars!

Notes

  • If the rhubarb is too tart, you can add an additional tablespoon or two of sugar to the filling mixture to balance the flavor.
  • These bars can be stored in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 1 week.
  • For a richer flavor, you can add a pinch of ground nutmeg to the oat mixture.
