Ingredients You Will Need
To make the soft sourdough dough you will need the following items measured accurately:
1 cup of sourdough discard at room temperature 3 cups of all purpose flour or unbleached bread flour 1 half cup of warm whole milk around 105 degrees Fahrenheit 1 quarter cup of granulated white sugar 1 large egg at room temperature 1 large egg yolk at room temperature 1 quarter cup of unsalted butter softened at room temperature 1 teaspoon of active dry yeast or instant yeast 1 teaspoon of pure vanilla extract 1 half teaspoon of fine sea salt 4 cups of neutral vegetable oil or canola oil for frying the dough
To make the smooth vanilla custard filling you will need the following items:
2 cups of whole milk 4 large egg yolks at room temperature 1 half cup of granulated white sugar 3 tablespoons of cornstarch 2 tablespoons of unsalted butter softened 2 teaspoons of pure vanilla bean paste or pure vanilla extract 1 quarter teaspoon of fine sea salt
To make the sweet outer sugar coating you will need:
1 cup of fine granulated white sugar or powdered sugar for rolling
Step by Step Method
Preparing the Smooth Vanilla Custard Filling
Step 1: Take a medium saucepan and pour in two cups of whole milk along with one teaspoon of vanilla extract. Place the saucepan on your stove over medium heat and warm it gently until small bubbles appear around the edges. Do not let the milk boil completely.
Step 2: While the milk is warming up take a heatproof glass bowl and combine four egg yolks half a cup of granulated sugar three tablespoons of cornstarch and a quarter teaspoon of fine sea salt. Whisk these ingredients together vigorously until the mixture becomes smooth pale yellow and slightly thick.
Step 3: Carefully pour a small stream of the warm milk into your egg mixture while whisking constantly. This step is called tempering and it prevents the egg yolks from scrambling when exposed to heat. Slowly add about half of the warm milk while whisking without stopping.
Step 4: Pour the warm egg and milk mixture back into the saucepan with the remaining heated milk. Place the saucepan back over low to medium heat on your stove.
Step 5: Whisk the mixture constantly as it cooks on the stove. After about five minutes the liquid will suddenly thicken into a smooth rich custard pudding texture. Continue whisking until big lazy bubbles pop on the surface.
Step 6: Remove the saucepan from the heat immediately. Stir in two tablespoons of softened unsalted butter and the remaining vanilla bean paste until fully melted and smooth.
Step 7: Pour the hot custard through a fine mesh strainer into a clean bowl to remove any tiny cooked egg bits. Cover the surface of the custard directly with plastic wrap so a hard skin does not form on top. Place the bowl in your refrigerator for at least two hours until completely cold and firm.
Making the Sourdough Discard Dough
Step 8: In a small bowl combine warm whole milk one teaspoon of sugar and one teaspoon of active dry yeast. Stir gently and let it sit for seven minutes until the top becomes foamy and bubbly.
Step 9: In a large mixing bowl or the bowl of a stand mixer combine your sourdough discard one egg one egg yolk foamy yeast mixture vanilla extract and the remaining quarter cup of sugar. Stir well until all wet ingredients are blended together smoothly.
Step 10: Add three cups of all purpose flour and half a teaspoon of fine sea salt into the wet mixture. Use a wooden spoon or the dough hook attachment on your mixer to combine everything into a shaggy dough ball.
Step 11: Begin kneading the dough on a lightly floured surface or in your stand mixer on low speed for about five minutes. Gradually add the quarter cup of softened butter one tablespoon at a time as you knead.
Step 12: Continue kneading for another six to eight minutes until the dough becomes soft smooth elastic and slightly tacky but not sticky. If the dough feels too wet add one tablespoon of flour at a time until workable.
Step 13: Shape the dough into a smooth round ball. Lightly oil a large bowl place the dough inside and cover the top tightly with a clean damp kitchen towel or plastic wrap.
Step 14: Place the bowl in a warm draft free spot in your kitchen to rise for about two hours or until the dough has doubled in size.
Shaping and Frying the Dough
Step 15: Gently punch down the risen dough to release air bubbles. Turn the dough out onto a lightly floured countertop or cutting board.
Step 16: Use a rolling pin to roll the dough out evenly until it is about half an inch thick all the way across.
Step 17: Use a three inch round biscuit cutter or glass rim to press out round circles from the dough. Place the cut dough rounds onto a baking sheet lined with parchment paper. Gather any leftover dough scraps reroll them once and cut additional circles.
Step 18: Cover the shaped dough rounds loosely with a lightweight towel and let them rise in a warm spot for about forty five minutes until puffy and soft.
Step 19: Pour four cups of neutral frying oil into a heavy pot or Dutch oven until it reaches a depth of two inches. Heat the oil over medium heat until a kitchen thermometer reads 350 degrees Fahrenheit.
Step 20: Carefully drop two or three puffy dough rounds into the hot oil using a slotted spoon. Do not overcrowd the pot or the oil temperature will drop too low.
Step 21: Fry each round for about two minutes on the first side until golden brown. Gently flip the dough using tongs or a fork and fry for another two minutes until golden brown on both sides.
Step 22: Use a slotted spoon to lift the fried dough out of the hot oil. Transfer them onto a wire rack lined with paper towels to drain excess oil for thirty seconds.
Step 23: While the dough is still warm roll each circle generously in a bowl of granulated white sugar until evenly coated on all sides. Allow them to cool down completely before filling.
Filling the Donuts with Cream
Step 24: Take your chilled vanilla custard out of the refrigerator and give it a quick stir with a spoon to make it smooth again. Transfer the custard into a piping bag fitted with a medium round tip.
Step 25: Take a wooden chopstick or small knife and poke a small hole into the side of each cooled fried donut. Wiggle the chopstick gently inside to create a hollow cavity without breaking through the other sides.
Step 26: Insert the tip of your piping bag deep into the side hole. Squeeze the piping bag firmly to fill the center with cold vanilla custard until the donut feels heavy and the cream swells slightly near the hole. Repeat for all remaining dough rounds and serve immediately.
Why This Recipe Is Special
This unique recipe brings together traditional baking techniques and modern zero waste kitchen ideals into one fantastic sweet treat. Using your sourdough discard gives you a simple way to eliminate food waste while enhancing the natural texture of your fried dough. The long slow fermentation of sourdough helps break down starches and gluten proteins making the final product much easier on your stomach and digestion compared to fast commercial bakery items. You gain full control over every single ingredient using real farm fresh eggs real cream pure vanilla beans and zero artificial chemicals or heavy industrial oils. Homemade desserts allow you to reduce refined sugars if desired without sacrificing the rich comforting taste everyone loves. The contrast between the warm crispy sugar coated exterior and the cold silky vanilla interior creates a taste sensation that store bought options simply cannot match. It offers a rewarding creative experience that fills your kitchen with beautiful smells and provides your family with high quality homemade food made with pure love.
Extra Tips for Better Taste
To take your homemade treats to an even higher level of deliciousness try using real vanilla bean pods instead of liquid extract in your custard recipe. Scraping fresh seeds directly from a vanilla pod infuses the cream with incredible aroma and gorgeous dark flecks of real flavor. Always monitor your frying oil temperature continuously using a digital probe thermometer because oil that is too cold will make your dough greasy while oil that is too hot will burn the outside before cooking the inside fully. You can add a pinch of freshly grated nutmeg or lemon zest to the dough mixture during the kneading phase to introduce a bright cozy background flavor. If you prefer an extra rich custard coating swap out half of the whole milk in the filling for heavy cream. For a fun seasonal twist you can mix half a teaspoon of ground cinnamon into your rolling sugar to create a warm cinnamon sugar exterior. Always make sure your fried dough is completely cool before filling with custard otherwise the heat will melt the cream and make the center runny.
