Description
Delightful dessert bars that combine tart rhubarb with a smooth custard layer, topped with buttery crumble.
Ingredients
Scale
- 14 oz fresh rhubarb, trimmed and chopped
- 5.3 oz granulated sugar (divided)
- 1 tablespoon fresh lemon juice
- 1 tablespoon cornstarch
- 8.8 oz all-purpose flour
- 3.5 oz rolled oats
- 5.3 oz unsalted butter, cold and cubed
- 3.5 oz light brown sugar
- 1/2 teaspoon salt
- 10 fl oz whole milk
- 2 large egg yolks
- 2.1 oz granulated sugar
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
Instructions
- Preheat your oven to 350°F and line a 9-inch square baking pan with parchment paper.
- In a saucepan, combine chopped rhubarb, 5.3 oz granulated sugar, lemon juice, and 1 tablespoon cornstarch. Cook over medium heat until rhubarb softens and thickens, about 8 to 10 minutes. Set aside to cool.
- In a large bowl, mix all-purpose flour, rolled oats, light brown sugar, and salt. Rub in cold butter until the mixture resembles coarse breadcrumbs.
- Press two-thirds of the crumble mixture into the bottom of the prepared pan to create an even base. Bake for 15 minutes until lightly golden, then let cool slightly.
- Heat whole milk until steaming. In a separate bowl, whisk egg yolks, 2.1 oz granulated sugar, and 2 tablespoons cornstarch until smooth. Gradually pour hot milk into the egg mixture while whisking. Return to saucepan and cook over medium heat, stirring continuously until thickened, about 2 to 3 minutes. Stir in vanilla extract.
- Spread the cooled rhubarb filling over the baked base. Pour custard over the rhubarb and sprinkle reserved crumble on top. Bake for an additional 30 minutes until golden and custard is just set.
- Allow to cool completely in the pan, then refrigerate for at least 2 hours before cutting into 16 bars.
