In a bowl of a food processor, add the flour, sugar, and salt. Add the cubes of butter and pulse about 8-10 times until the flour is incorporated with the butter, and the butter is in pea sized pieces. It is totally cool if the butter pieces are larger than pea size.

In a separate bowl, beat the egg with the milk, then add them all at once to your dry ingredients. Pulse a few times until the flour is moistened. This will take about 7-8 pulses and you'll be left with a very wet looking dough which will resemble sugar cookie dough. This is fine.

Turn the dough over a lightly floured surface and gently knead a couple of times. Divide the dough in 2 and gather the dough pieces in a rough square. Lightly sprinkle flour over top of the dough and wrap in plastic wrap or place in a zip lock bag. Place in the freezer for about 30 minutes. While the dough is chilling, make the filling.

In a medium bowl combine the cream cheese, confectioners' sugar, and vanilla bean paste. Mix until the cream cheese is softened and ingredients are fully combined. Wrap the surface of the bowl with plastic wrap and set aside. Measure out the strawberry jam and place in the refrigerator. Make the glaze.

In a small bowl, combine the powdered sugar, milk, and strawberry jam until combined. Wrap the surface of the bowl with plastic wrap and place this in the refrigerator as well.

Line 2 cookie sheets with parchment paper and preheat the oven to 350 degrees Fahrenheit.

Remove one piece of dough from the freezer. Turn the dough onto a floured surface and roll out a 9x12 inch rectangle to about 1/8 of an inch in thickness. If you can't get a 9x12 inch rectangle, get as close as you can. If its a square, its a square. No one is judging you. Trim the edges of the dough with a pizza cutter or a knife to make a nice rectangle (Or a square. Still not judging you)

Using a square biscuit cutter, as many 3x3 inch squares as you can. Alternatively, you can use a pizza cutter, cutting each side into quarters, creating the squares. We're trying to cut 12 small squares. Note: You may have to re-roll the dough to get the 12 squares. If this is the case, gather the dough pieces into a rough square. Freeze for a few minutes, then roll and cut once more. Place the squares onto your prepared cookie sheet and place the sheet in the refrigerator to chill as you cut the second piece of dough in the same way as the first. Remove the first batch of squares from the refrigerator and place the newly cut batch of squares in the refrigerator to chill.

Are you ready to fill? Let's fill. Remove the filling, jam, and glaze from the fridge. Spoon about 1 teaspoon of filling onto the center of the dough square. Spoon about 1 teaspoon of jam either on top or next to it. Repeat with all dough squares.

Remove the second batch of dough squares from the refrigerator and use them to top the filled dough squares. Crimp the sides with a floured fork. Use the tines of the fork to create a few vent hole on surface of each mini pie. Brush the surface with beaten egg and place in the oven. Bake for 25 to 30 minutes until the tops are golden brown. Remove from the oven and allow to cool completely before glazing.

Place a wire rack over a piece of parchment. Place the mini pies on the rack and pour the glaze over the mini pies. Allow the glaze to dry completely before serving.
