Ingredients
Method
- Preheat oven to 350°F (175°C). Line an 8x8-inch pan with parchment paper.
- Prepare the filling: In a saucepan over medium heat, cook rhubarb, sugar, lemon juice, and cornstarch until thick and bubbly (about 8–10 minutes). Stir in vanilla. Let cool.
- Make the oat mixture: In a large bowl, mix oats, flour, brown sugar, cinnamon, baking soda, and salt. Stir in melted butter until crumbly.
- Assemble: Press 2/3 of the oat mixture into the bottom of the pan. Spread rhubarb filling on top. Crumble remaining oat mixture over the filling.
- Bake for 35–40 minutes until golden brown. Cool completely before cutting into bars.
