With apple-cinnamon filling
With strawberry jam filling
With poppy seed filling
With banana filling
Pastry
2 cups (340g) all-purpose flour
1 tbsp sugar
1 tsp salt
1 cup (225g) unsalted butter, cut into cubes
1 large egg
2-3 tablespoons milk
Whisk together the flour, sugar, and salt. Work in the butter with your fingers until pea-sized lumps of butter are still visible, and the mixture holds together when you squeeze it. Transfer the mixture to a large bowl. Whisk the egg and milk together and stir them into the dough, mixing just until everything is cohesive, kneading briefly on a well-floured counter if necessary. Refrigerate while you prepare the fillings.
Remove it from the refrigerator and allow it to soften and become workable, about 15 to 30 minutes. Place one piece on a lightly floured work surface, and roll it into a rectangle about 3mm thick (I rolled it into ~25x33cm rectangle). Repeat with the second piece of dough. Set trimmings aside. Cut dough into 20 rectangles. (I didn't get 20 rectangles so I re-rolled the trimmings).
Beat the additional egg and brush it over the entire surface of the first dough. This will be the “inside” of the tart; the egg is to help glue the lid on. Place a heaping tablespoon of filling into the center of each rectangle. Place a second rectangle of dough atop the first, using your fingertips to press firmly around the pocket of filling, sealing the dough well on all sides. Press the tines of a fork all around the edge of the rectangle. Repeat with remaining tarts.
Gently place the tarts on a parchment-lined baking sheet. Prick the top of each tart multiple times with a fork. Refrigerate the tarts for 30 minutes, while you preheat your oven to 180 degrees C.
