Ingredients
1 cup all purpose flour
3/4 cup old fashioned oats
1 cup brown sugar (packed)
1/2 cup melted butter
1 teaspoon ground cinnamon
4 cups diced rhubarb (about 1 pound, from about 6 stalks)
1 cup granulated sugar
2 1/2 tablespoons cornstarch
1 cup water
1 teaspoon vanilla extract
Instructions
1-Preheat and prep: Preheat oven to 350°F and grease a 9×9 inch baking dish.
2-Make the crumble: Whisk flour, oats, brown sugar, and cinnamon; stir in melted butter and a pinch of salt until coarse crumbs form.
3-Create the crust: Press half of the crumble mixture firmly into the prepared dish to form an even, compact crust.
4-Add the rhubarb: Spread diced rhubarb evenly over the crust without peeling.
5-Make the sauce: Combine sugar, cornstarch, water, and vanilla in a saucepan; cook over medium-low, stirring constantly, until thick and clear, 3–5 minutes.
6-Pour the sauce: Pour the hot sauce evenly over the rhubarb, letting it seep down without stirring.
7-Add the topping: Sprinkle the remaining crumble mixture over the top; do not press down.
8-Bake: Bake for 1 hour until the topping is golden brown and filling is bubbly; cool 10–15 minutes before serving.
