To make Pie crust : combine all ingredients(except flour) then beat with electric mixer until smooth. (make sure butter and egg in room temperature).Then add the sifted flour, blend well.Put the dough in the fridge for about 30mins or longer.On a lightly floured surface, roll the dough making sure it doesn't stick to the counter. Cut with round cookie cutter. Place them into the mold(i use mini muffin pan)and bake in the preheat oven in 350°F or 175°C about +/- 15mins

To make the custard cream : Warm up the milk until hot, but not boiling.In a medium size pan, whisk the egg yolks with the sugar, the corn starch and the vanilla extract until smooth and fluffy. Add the milk a little bit at a time, whisking well so that no lumps form. Whisk in the rest of the milk. 

Place the pan over medium heat and stir continuously until it reaches a slow boil. The cream will thicken, so be careful not to let it stick to the bottom. Lower the flame and cook for a couple of more minutes, until you reach the desired thickness. Pour the cream in a glass bowl and let it cook down.Cover with plastic wrap and refrigerate for at least one hour.

When the tartlet shells cool down completely and you are ready to serve, cut the fruits into thinly sliced

Fill the cookie cups with the custard cream, top with the fruits. Store in the refrigerator if not eaten right away.Enjoy =)
