Rhubarb oat crumble
This delicious rhubarb dessert recipe is so perfect as it is there’s no need to add any others flavors with the rhubarb in the filling. Typically rhubarb is paired with strawberries or apples. But in this simple recipe sweetened rhubarb is all you need! Although, you can feel free to toss in some fresh or frozen berries, peaches or apple slices if you’d like.
Ingredients
- Rhubarb – Fresh rhubarb stalks, chopped into roughly 1″ bite – sized pieces. Add any mixture of fruit like strawberry rhubarb crumble or peach rhubarb crumble. But the sugar and flour will need to be adjusted when adding sweeter ingredients.
- Granulated sugar – Rhubarb tastes tart and a little bitter and not at all sweet. So the filling uses a lot of granulated sugar. If substituting a different fruit for the crumble filling make sure to decrease the sugar. You can also feel free to adjust the sugar amount to your liking.
- Oats – rolled oats or quick cooking oats can be substituted in this rhubarb oat crumble.
- Brown sugar – Adds a perfect flavor to the crumble. And helps keep the topping somewhat soft and chewy with a crunchy bite.
- Butter
- All purpose flour
- Spices – this rhubarb crumble with ginger and cinnamon uses the ground spices in both the filling and the crumble topping.
- Baking powder
- Salt
Step by step instructions
- Wash and chop rhubarb stalks into roughly 1″ pieces. Add granulated sugar and flour to the fruit filling. Toss to coat.
