100 g eggs (Approx. 2 eggs)

128 g whole milk (cold)

75 grams sugar

7 grams salt

75 grams unsalted butter (softened, cubed)

360 g whole milk

1 vanilla bean pod (or 1 tsp vanilla extract)

25 g unsalted butter

2 litre frying oil

200 g sugar (for coating)

Wskazówki

Stiff Levain

Mix sourdough starter, water, and flour in a bowl. Cover, and rise in a warm spot (75°F-78°F/24°C-26°C) for 8-10 hours, until tripled in size.

Main Dough

Add the flour, stiff levain, eggs, whole milk, sugar, and salt to the bowl of your stand mixer fitted with a dough hook. Mix until just combined. It does not matter if the dough is a bit lumpy at this point. Cover, and rest/autolyse for 30 minutes.

After the autolyse, continue mixing for 5 minutes.

After 5 minutes, you can slowly start to add cubed, softened butter. When all the butter is added, scrape down the sides of your bowl and continue mixing at medium speed for 15-25 minutes. Do the window-pane test to check if your dough is ready.

Transfer the dough to a clean bowl, cover, and proof in a warm spot (75°F-78°F/24°C-26°C) for 6 hours. If you don't own a dough proofer, you can keep the dough in the oven with the light turned on and the oven door slightly open.

I like to do two gentle folds during proofing, one after 1,5 hours and one after 3 hours.

After 6 hours, place the dough in the fridge and cold-proof for 6-8 hours.

Vanilla Pastry Cream

Start by gathering all your ingredients.

In a bowl, whisk together egg yolks, sugar, corn starch, and salt.

Cut the vanilla bean pod in half (lengthwise) and scrape off the vanilla bean with a knife.

In a medium-sized pot, combine the milk and vanilla bean. Heat up over medium heat until you can see tiny bubbles forming around the edges of the pot, almost to a boil.

Take the pot off the heat and slowly pour it over the egg mixture a little at a time while constantly whisking.

Place a fine-mesh strainer over the pot and strain everything back into the pot. Heat up over medium heat, still constantly whisking, until the pastry cream is thick and shiny.

Remove from heat and mix in the butter. If you're using vanilla extract, you want to mix it in now.

Transfer to a bowl, cover with plastic wrap that is touching the entire surface of the cream. This is to prevent skin from forming on top of the pastry cream. Cool to room temperature, then place it in the fridge.

Shaping And Final Proof

Divide the dough into 15 equal pieces (60g each) and roll into seamless rounds. Place the shaped donuts on baking trays lined with floured parchment paper cut into about 5in/12 squares. The parchment paper pieces are for easier transfer later on. Loosely cover the trays with plastic wrap.

Place the baking trays in the oven with the light turned on and the door slightly open. You want the temperature to be around 78°F/26°C. You can also use a proofer box if you own one. Proof the donuts for about 10-14 hours or until they've doubled in size.

Fry The Doughnuts

Pour oil into a Dutch Oven or heavy bottomed pot set over medium heat. Heat the oil to 180 °C-185°C/356°F-365°F. A thermometer is highly recommend to manage the temperature.

Carefully lower the doughnuts into the oil and fry them for about 2 minutes each side. You want the top-side of the dough pieces to hit the oil first.

Remove from oil with a metal slotted spoon and transfer to a cooling rack lined with paper towels.

Toss the fried doughnuts in sugar while they're still warm.

Repeat on all remaining doughnuts.

Assembly

Take your vanilla pastry cream out of the fridge and give it a good stir. Insert a small knife into the center of the cooled doughnuts (anywhere on the white line) to make a hole. With a piping bag, fill each doughnut with vanilla pastry cream.
