- 1 cup granulated sugar
- 1 tablespoon cornstarch
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 cup rolled oats
- 1/2 cup brown sugar, packed

Ingredient Notes and Substitutions
- Rhubarb: This sour vegetable balances sweetness. If unavailable, try tart apples or sour cherries.
- Sugar: Sweetens the rhubarb and topping. Coconut sugar is a great alternative for a deeper flavor.

How to Make Rhubarb Crumble
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your crumble bakes evenly and gets that lovely golden color.
Step 2: Prepare the Rhubarb
In a mixing bowl, combine the chopped rhubarb, granulated sugar, cornstarch, and vanilla extract. This mixture will allow the rhubarb to release its natural juices and create a deliciously tangy filling.
Step 3: Pour the Filling into the Dish
Transfer the rhubarb mixture into a 9-inch baking dish. Spread it evenly to ensure every bite is packed with flavor.
Step 4: Make the Crumble Topping
In another bowl, mix the flour, oats, brown sugar, and salt. This combination will create a crumbly texture that contrasts beautifully with the soft rhubarb.
Step 5: Add the Butter
Using your fingers or a fork, incorporate the softened butter into the dry ingredients until crumbly. This step is crucial for achieving that delightful crunch on top.
Step 6: Top the Rhubarb
Evenly spread the crumble topping over the rhubarb mixture. This layer will soak up some of the juices while baking, creating a delightful texture.
Step 7: Bake the Crumble
Bake in the preheated oven for 30-35 minutes until the topping is golden brown and the rhubarb is bubbling. The aroma will be irresistible, trust me.
Step 8: Cool and Serve
Let the crumble cool for about 10 minutes before serving. This allows the filling to set slightly, making it easier to scoop.
Pro Tip: For an extra flavor boost, add a teaspoon of cinnamon or ginger to the crumble topping!
