Pastry
- 175 g plain flour
- 100 g unsalted butter (cold and cubed)
- 1 tbsp icing sugar
- 1 egg yolk
- splash of cold water (about 1 tbsp)
Filling
- 65 g plain flour
- 150 ml full-fat milk
- 250 g unsalted butter
- 250 g light brown soft sugar
- Prepare Pastry: Add the plain flour and icing sugar to a large bowl. Incorporate the cold cubed unsalted butter by rubbing the mixture together with your fingertips until it resembles fine breadcrumbs.
- Form Pastry Dough: Add the egg yolk and about 1 tablespoon of cold water into the bowl. Mix with your hand or a spatula until the dough comes together, kneading a bit if necessary. Alternatively, pulse all ingredients in a food processor until the mixture starts binding.
- Chill and Roll Pastry: Grease and flour a 9-inch (23 cm) loose-bottomed tart tin. Roll the pastry on a lightly floured surface to about 1-2 coin thickness. Press the pastry evenly into the tart tin, trim edges neatly, and fill any gaps with pastry scraps. Refrigerate for 30 minutes.
- Blind Bake Pastry: Preheat the oven to 200ºC (fan 180ºC). Line the pastry with baking parchment and fill with baking beans or rice. Bake blind for 15 minutes to set the crust.
- Finish Baking Pastry: Remove the parchment and baking beans, then bake the pastry for another 5 minutes or until golden brown and cooked through. Allow the tart case to cool completely.
- Make Filling Base: In a small bowl, whisk together 65 g plain flour and 75-100 ml of milk until a smooth, lump-free paste is formed.
- Heat Butter and Milk: In a medium saucepan, combine 250 g unsalted butter and the remaining milk. Heat gently until the butter melts completely.
- Add Sugar and Combine: Stir in 250 g light brown soft sugar over low to medium heat until it dissolves fully.
- Thicken Filling: Slowly pour the flour and milk paste into the saucepan, stirring continuously. Continue heating over medium-low heat, whisking or stirring with a spatula to prevent lumps and sticking, until the mixture thickens into a smooth custard. Sieve to remove any lumps if necessary.
- Assemble Tart: Pour the thickened butterscotch filling evenly into the cooled tart shell.
- Chill to Set: Refrigerate the assembled tart for 3-4 hours or preferably overnight to allow the filling to set firmly.
- Serve: Once set, carefully remove the tart from the tin and enjoy this rich butterscotch dessert.
Notes
- Using cold butter in the pastry ensures a flaky crust.
- Blind baking the pastry prevents a soggy bottom when adding the moist filling.
- Stirring the filling continuously while heating prevents lumps and ensures a smooth texture.
- Allowing the tart to chill overnight results in a firmer filling and better flavor development.
- You can substitute light brown sugar with dark brown sugar for a richer butterscotch flavor.
- Ensure the pastry is fully cooled before adding the filling to avoid melting the base.
