Ingredients You Will Need
For the Sourdough Donut Dough: All purpose flour: Four cups Active sourdough discard unfed and room temperature: One cup Warm whole milk: Three quarters of a cup Granulated white sugar: One third of a cup Unsalted butter melted and slightly cooled: One third of a cup Large eggs: Two whole eggs Active dry yeast: One packet or two and one quarter teaspoons Salt: One teaspoon Pure vanilla extract: One tablespoon Vegetable oil for frying: Four to six cups
For the Vanilla Custard Filling: Whole milk: Two cups Granulated white sugar: One half cup Egg yolks: Four large egg yolks Cornstarch: One third of a cup Unsalted butter cubed and room temperature: Two tablespoons Pure vanilla bean paste or extract: Two teaspoons Salt: One quarter teaspoon
For the Donut Coating: Granulated white sugar: One cup Ground cinnamon: One tablespoon
Step by Step Method
To begin making your delicious sourdough discard vanilla custard filled donuts, you must first prepare the rich vanilla custard so it has plenty of time to cool down completely in the refrigerator. Grab a medium saucepan and pour in two cups of whole milk, placing it over medium heat on your stovetop until it comes to a gentle simmer with small bubbles forming around the edges. While the milk is warming up, take a clean mixing bowl and whisk together the four large egg yolks, one half cup of granulated sugar, one third of a cup of cornstarch, and one quarter teaspoon of salt until the mixture turns pale yellow and smooth. Once the milk is simmering, slowly pour about one half of the hot milk into the egg yolk mixture while whisking constantly so the eggs do not scramble from the heat. Pour that tempered egg mixture back into the saucepan with the remaining warm milk and whisk continuously over medium heat until the liquid thickens into a glossy pudding. Remove the saucepan from the heat source and stir in the two tablespoons of cubed butter and two teaspoons of vanilla bean paste until everything is fully melted and velvety smooth. Transfer your finished custard into a shallow glass dish, press plastic wrap directly onto the surface to prevent a skin from forming, and place it in the refrigerator to chill for at least three hours.
Now that your custard is resting happily in the fridge, you can turn your complete focus to creating the magnificent sourdough donut dough from scratch. In a large mixing bowl or the bowl of a stand mixer fitted with the dough hook attachment, combine the warm whole milk, active sourdough discard, granulated sugar, melted butter, whole eggs, active dry yeast, salt, and vanilla extract. Whisk these wet ingredients together thoroughly until the sourdough discard is completely dissolved and the mixture looks uniform and slightly frothy on top. Gradually add the four cups of all purpose flour into the wet mixture, starting slowly so the flour does not fly everywhere and mixing until a sticky dough begins to form inside the bowl. Knead the dough either by hand on a lightly floured countertop for about ten minutes or let your stand mixer run on medium speed for seven minutes until the dough becomes smooth, elastic, and slightly tacky. Form the kneaded dough into a neat round ball and place it inside a lightly oiled mixing bowl, covering the top tightly with a clean kitchen towel or plastic wrap. Allow the dough to rise in a warm spot in your kitchen for two to three hours or until it has doubled nicely in size, benefiting from the natural power of the yeast and sourdough discard.
Once your dough has completed its first rise, gently punch it down to release the trapped air bubbles and turn it out onto a clean work surface that has been lightly dusted with all purpose flour. Roll the dough out evenly with a rolling pin until it reaches a thickness of about three quarters of an inch, ensuring you do not roll it too thin or your donuts will not puff up properly. Use a round biscuit cutter or a drinking glass measuring about three inches across to cut out neat round circles from the rolled out dough, placing each circle onto a parchment lined baking sheet. Gather any leftover dough scraps, gently press them back together, roll them out again, and cut out more rounds until you have used every last bit of the dough. Cover your cut out donut rounds loosely with a clean towel and let them rest for a second rise in a warm area for about forty five minutes until they look puffy, light, and airy.
While the second rise is happening, pour your vegetable oil into a large heavy bottomed Dutch oven or deep fryer until it reaches a depth of about two inches, attaching a candy thermometer to monitor the temperature. Heat the vegetable oil over medium heat until the thermometer registers precisely three hundred and fifty degrees Fahrenheit, which is the absolute ideal temperature for frying golden and fluffy donuts without burning the outside. Carefully drop three or four donut rounds into the hot oil at a time, making sure not to overcrowd your pan because that will cause the oil temperature to drop and make the donuts greasy. Fry the donuts for about two to three minutes on the first side until they turn a gorgeous golden brown color, then gently flip them over with a slotted spoon to fry the other side for another two minutes. Remove the cooked donuts from the hot oil using your slotted spoon and transfer them immediately onto a wire cooling rack set over paper towels to drain any excess oil away efficiently. While the donuts are still warm, toss them gently in a shallow bowl filled with your mixture of one cup of granulated sugar and one tablespoon of ground cinnamon until they are completely coated.
The final exciting step of this baking adventure is filling your gorgeous cinnamon sugar coated donuts with that wonderfully chilled and creamy homemade vanilla custard you prepared earlier in the day. Take a small sharp paring knife and poke a small hole into the side of each warm donut, wiggling the knife slightly inside to create a small hollow pocket for the delicious filling. Transfer your chilled vanilla custard from the refrigerator into a piping bag fitted with a long round metal filling tip, or a sturdy ziplock bag with the corner snipped off cleanly. Insert the piping tip into the hole you created in the side of the donut and gently squeeze the bag until you feel the donut expand slightly in your hand with creamy goodness. Repeat this rewarding process for every single donut in your batch, arranging them neatly on a beautiful serving platter as you finish filling them one by one. Serve these magnificent sourdough discard vanilla custard filled donuts immediately to your eager family or guests while they are still fresh, warm, and utterly irresistible.
Why This Recipe Is Special
This remarkable recipe stands out far above ordinary pastry recipes because it brilliantly combines the rustic art of sourdough baking with the timeless indulgence of a classic custard filled bakery treat. One of the greatest benefits of this recipe is how it honors the zero waste kitchen philosophy, turning leftover sourdough discard that might otherwise go to waste into something truly extraordinary for your table. Health conscious bakers also appreciate that using homemade ingredients eliminates the artificial stabilizers, high fructose corn syrup, and hydrogenated oils commonly packed into commercial grocery store pastries. From a taste perspective, the flavor profile is simply unmatched; the mild fermented tang of the sourdough discard provides a wonderful balance against the ultra rich, sweet, and aromatic vanilla bean custard filling. Furthermore, the texture contrast between the crisp, cinnamon sugar coated exterior and the pillowy soft interior creates a multi sensory eating experience that brings pure joy with every single bite.
Extra Tips for Better Taste
If you want to take your sourdough discard vanilla custard filled donuts to an even higher level of gourmet perfection, consider trying a few of these creative flavor enhancements and professional baking secrets. For an extra luxurious custard filling, you can scrape the seeds from a real vanilla bean pod directly into the warming milk instead of using standard vanilla extract or paste. If you love chocolate just as much as vanilla, try dipping the top half of your filled donuts into a rich dark chocolate ganache after filling them instead of tossing them in cinnamon sugar. Always make sure your vegetable oil stays right around three hundred and fifty degrees Fahrenheit during the entire frying process because oil that is too hot will burn the outside while leaving the middle raw. If you do not have a piping bag for the custard, a simple heavy duty plastic food storage bag with the corner cut off works wonderfully as an improvised pastry tool. Finally, remember that these donuts taste absolute best when eaten fresh on the day they are made, but you can store any leftover unfilled donuts in an airtight container for a quick morning snack.
