Boston Cream

For the Donuts

Warm up the milk slightly, it should be warm but not too warm that you feel discomfort when touching it. Add the yeast & whisk, allow the yeast to activate for 10 minutes or so, the mixture should be fluffy then.
Add the rest of the ingredients & using a stand mixer mix the dough at low speed for 8 - 10 minutes. You can do this by hand as well, just knead the dough for an extra 4 minutes or so. The dough should be fluffy & slightly sticky, transfer the dough to an oiled bowl & allow it to rise for at least 2 hours in a warm environment.
Roll the dough in a floured surface until its around 1 ½ inch thick, using a cookie cutter (or a glass if you don't have one) cut up the dough into flat circles. Repeat the process until you are done with the dough.
Cover the donuts with a kitchen towel & allow them to rise one more time for 1 hour.
Heat up enough oil to fry the donuts (around 3 cups) in medium high heat (if you have a kitchen thermometer the ideal heat should be 350F).
Fry each donut for 2 - 3 minutes each side, do not overcrowd them while cooking.
Set them on a drying rack & repeat the process with the rest of the donuts.
Allow the donuts to cool down enough for you to hold them & not feel any discomfort. Using a chopstick pierce a hole in the middle of the donut & wiggle it around to open up space for the custard. Make sure you do this with all the donuts, set them aside.

For the Custard

In a large pot whisk all the ingredients together. Bring the mixture to a medium-high heat & whisk constantly. It will eventually start to thicken. Continue whisking until it's a thick paste.
Set aside & allow it to cool down completely before filling up the donuts.

Chocolate Glaze

Melt the chocolate & butter in the microwave (around 30 seconds) mix well until you have a smooth glaze.

Donut Assembling

Transfer the custard to a piping bag. Place the tip on the home of the donut you previously made with the chopstick & fill them up until the custard comes a bit out of the hole. Now, dip the top of the donut on the chocolate glaze making sure the top is fully covered by chocolate. Set aside & repeat the process with the rest of the donuts.
