Directions
Place warm milk, yeast and 1 teaspoon granulated sugar in bowl of electric mixer. Using a wire whisk, stir mixture until yeast granules are evenly dispersed. Let stand for 3 minutes until yeast is dissolved and mixture begins to foam.
Add 1 & 1/2 cups flour to yeast mixture. Using paddle attachment (or with hands) beat on low speed 2 minutes. Remove paddle attachment and cover bowl with plastic wrap. Let stand at room temperature 45 minutes. Dough will have increased in volume.
Thoroughly grease a large bowl with 1 tablespoon room temperature butter and set aside. To dough, add remaining butter and sugar, yolks, salt, cardamom and nutmeg. Mix on low speed until blended. Add 1 & 1/2 cups remaining flour, 1/2 cup at a time. Beat dough on medium speed 5 minutes. Dough will not form a ball – it will be soft and very sticky. You can add the remaining flour 1 tablespoon at a time, as necessary.
Scrape dough into prepared bowl, turning over dough so that the top of it is greased. Cover with plastic wrap. Let dough rise at room temperature about 2 hours, or until it has slightly more than doubled in volume. (Rising time will depend upon room temperature.)
After dough has risen/doubled in size, line a baking sheet with parchment or wax paper and evenly dust with flour. Dust a clean work surface with flour. Turn out risen dough onto surface and gently press down on it to deflate. With your hands, flatten dough into a rectangle about 1/2-inch thick. Cover loosely with plastic wrap and let dough rest 5 minutes.
Using a floured 2 & 1/2-inch round biscuit or cookie cutter (I used a beer glass), cut out about 12 to 14 rounds of dough. With a floured spatula, gently transfer rounds to prepared baking sheet, reshaping them if necessary. Leave at least 1-inch between donuts to allow for expansion. Let donuts rise for about 20 minutes, or until almost doubled in size.
Pour enough oil in a deep-fat fryer or large straight-sided saucepan to come halfway up sides. Oil should be a depth of 2 to 3 inches. Heat oil to 365ºF. Line a baking sheet with paper towels. Fry donuts, 3 or 4 at a time, for 1 to 1 minute 30 seconds or until golden brown, flipping once in between. (The midline of the doughnut will be lighter than the rest of it) Remove donuts from hot oil using a slotted spoon and transfer them to paper towel-lined baking sheet to drain and cool.
Prepare your filling by boiling milk then Add sugar and NATIONAL VANILLA CUSTARD . Cook till it become thick .
Prepare your glaze by heating the chocolate and butter in medium saucepan over low heat until butter and chocolate are completely melted and mixture is well blended. Add the sugar and milk and mix well until smooth. Feel free to add more milk if you want to thin it out a bit more.
Fill a pastry bag with the filling. With a knife (or even your finger) poke a hole into the side of each donut, trying to make some space into the center. Just be gentle as you're doing this. Pipe the filling into hole in middle of each donut until pastry cream bulges out and donut feels full. Wipe off any excess cream. Place filled donuts on rack after they are filled.
Dip top of each filled donut into bowl of warm chocolate glaze, letting excess glaze drip back into bowl. Place glazed donuts back onto rack to set. Let sit for 30 minutes before serving. The donuts are best when prepared and served on the same day, otherwise store at room temperature for a few days in an air tight container
