In a medium bowl, stir together soft butter and powdered sugar until smooth. Mix in vanilla. Add corn starch and stir until smooth. Gradually incorporate flour and salt, stirring until dough forms a cohesive mass.

Divide dough into 24 equal portions (approximately 25-26g each). Form each portion into a ball, press gently into prepared muffin cups, and create an indentation using a teaspoon or 1/2 tablespoon measuring spoon. Repair any edge cracks by pressing dough together. Repeat until all cups are filled.

Bake tarts in the preheated oven for 18-22 minutes, or until outer edges are golden brown. Quickly reinforce indentations by pressing again with the measuring spoon. Cool shells in pan for 10 minutes, then transfer to a cooling rack.

Fill each tart shell with a rounded teaspoon of prepared apple filling.

Allow caramel to set for 10 minutes before serving. Store tarts at room temperature for 8-10 hours or store tart shells and apple filling separately until a few hours before serving.
