Ingredients
For the crisp topping
1 and ¾ cups (150 g) of rolled oats (also called old-fashion oats)
¾ cup (175 g) of light brown sugar
1 and ¼ cups (150 g) of all-purpose flour
1 scant cup (200 g) of cold butter, cut into 1 inch (2.5 cm) cubes (scant meaning just a little less than a whole cup)
¼ teaspoon of flaky sea salt
For the rhubarb filling
35.5 ounces (1 kg) of rhubarb, cut into 1 inch (2.5 cm) pieces
2 tablespoons (25 g) of light brown sugar
½ teaspoon of vanilla powder
3 and ½ tablespoons (50 g) of cold unsalted butter, cut into ½ inch (1 cm) cubes
Instructions
Preheat the oven to 375°F (190°C).
Make the crisp topping:
Note: you can either use your hands (my preferred choice here) or the flat beater of your stand mixer to combine the ingredients together.
- In a mixing bowl, add flour, light brown sugar, rolled oats, and salt. Stir until well combined.
- Add the cold butter cubes and combine the ingredients until they resemble chunky breadcrumbs. I like keeping some bigger chunks to create an extra layer of crispiness.
- Set aside.
Make the rhubarb filling:
- Wash the rhubarb stalks thoroughly and cut them into 1-inch (2.5 cm) pieces.
- Transfer the rhubarb pieces to a 10-inch (26 cm) skillet or 11×7 inch (28×18 cm) rectangular baking pan.
- Sprinkle light brown sugar, and vanilla powder on top of the rhubarb.
- Add the cold butter cubes, and spread evenly.
Assemble and bake the rhubarb crisp:
- Add the crisp topping on top of the filling. Spread until the rhubarb filling is evenly covered.
- Bake for 45-50 minutes or until the crisp topping is golden brown and the rhubarb soft and bubbling beneath.
- Let it cool down and enjoy slightly warm with a scoop of vanilla ice cream or a dollop of clotted cream!
Nim Keys
- In a vast majority of cases (when the rhubarb is store-bought), no need to peel it. However, in some instances (mostly for home-grown rhubarb), the skin can be pretty thick. In this case, you can peel the tougher parts for a smoother result.
- If you don’t have vanilla powder on hand: substitute the light brown sugar and vanilla powder with 2 tablespoons (12 g) of vanilla sugar. The vanilla flavor will be more subtle but it does the trick!
- If you wish to veganize this Old-Fashioned Rhubarb Vanilla Crisp, just replace the unsalted cultured butter with the plant-based unsalted butter of your choice.
- The proportions of this recipe are for a 10-inch skillet (26 cm) or 11×7 inch (28×18 cm) rectangular baking pan and serve 6-8 servings. Feel free to divide the recipe in half if you are having a date night or a smaller crowd over.
