Oat Crust & Crumble:
- 1 ½ cups old-fashioned oats

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.

Bake for 35–40 minutes until golden brown. Cool completely before cutting into bars.
