Instructions
Arrange oven rack to bottom third of the oven. Preheat oven to 375°F. Grease a standard 12-cup muffin tin and set aside.
Roll chilled dough on a lightly floured surface to about ⅛ inch thick. If too firm, knead briefly to soften. Cut out circles with a 4-inch cutter. Press each circle into a standard 12-cup muffin pan, making sure the edges reach the top. Reroll dough scraps as needed. Chill the pan in the freezer while preparing the filling.
For the filling, whisk together brown sugar, melted butter, egg, vinegar, vanilla, and salt in a bowl.
Divide the filling evenly into each cup. Bake at 375°F for about 14 to 15 for a runny filling and 18 to 20 minutes for a firmer filling, until the tarts are golden and set. Cool briefly, loosen edges with a knife, and let cool completely before removing. Serve at room temperature.
Notes
Store the butter tarts in an airtight container in the fridge for up to 5 days.
