In a large mixing bowl, combine the flour, granulated sugar, salt, and baking powder. Mix well. Cut in the butter until the mixture resembles coarse crumbs.

Add Wet Ingredients

In a separate bowl, whisk together the eggs, milk, and vanilla extract. Add this mixture to the dry ingredients and stir until just combined.

Shape the Pastries

On a floured surface, roll out the dough to about 1/2 inch thickness. Cut into your desired shapes (squares, circles, etc.) and place on a baking sheet lined with parchment paper.

Add Filling

Place a spoonful of your choice of fruits in the center of each pastry. Fold over the edges and seal with a fork.

Bake

Preheat the oven to 375°F (190°C). Bake the pastries for 20-25 minutes or until golden brown. Let cool.

Finish with Sugar

Dust the cooled pastries with powdered sugar before serving.
