Crafting the perfect bakery-style custard doughnut is a difficult but achievable goal. Whether you’re a professional pastry chef or a home baker, the key to unlocking the secrets of creating a delicious, tender, and golden-fried doughnut lies in the careful selection of ingredients and attention to detail throughout the process.

When selecting ingredients, be sure to use high-quality all-purpose flour and unsalted butter. For the doughnut itself, it is essential to use whole eggs and egg yolks, which will give the custard donuts a richer flavor and a softer texture. The butter should also be soft and at room temperature in order to ensure a smooth and even mixing of the ingredients.

Selecting Ingredients for Custard Donuts

When selecting ingredients for custard donuts, it is important to keep in mind quality and flavor. Using the best ingredients you can find will ensure that your donuts are of the highest quality and will provide a delicious and satisfying experience for your customers. Start by choosing an appropriate flour for your donut batter. Different types of flour will yield different results, so it is important to experiment and find the one that produces the best results. When it comes to the custard, fresh ingredients like eggs, cream, and sugar should be used in order to get the most flavor out of the custard. It's also important to pick a good quality vanilla extract to add depth and complexity to the custard.

Filling & Shaping 

Once your dough has risen, it’s time to fill and shape your custard doughnuts! 

• - Start by rolling out your dough on a lightly floured surface into ½ inch thickness, then cut out circles using either a biscuit cutter or cupcake tin (you can also use cookie cutters if desired). 
• - Place each circle onto parchment paper lined baking sheets, then spoon some prepared custard filling onto half of each circle, leaving about ¼ inch border around the edges before folding over the other half of the circle pressing edges together with fingers or fork tines (you can also use egg wash as glue). 
• - Allow filled circles to rest on parchment paper while preparing fryer oil (canola oil works best). 
• - Heat fryer oil to 375°F, then gently drop filled circles one at a time into hot oil using a slotted spoon, turning once after about 30 seconds or when golden brown color appears. 
• - Then remove from the fryer with a slotted spoon allowing excess oil to drain off before transferring them onto a paper towel-lined plate or tray (this will help absorb any remaining excess oil). 

Glazing & Decorating 

Now that your custard doughnuts are fried, it’s time for glazing!

• - In a medium-sized bowl, combine powdered sugar with warm water stirring until the mixture becomes thick but still pourable (add more water if needed); 
• - Then dip the tops of cooled doughnuts into the glaze allowing excess to drip off before transferring back onto a parchment paper lined tray or plate (you can also drizzle glaze over the top using a spoon if desired). 
• - To decorate, sprinkle some colored sprinkles over the top while the glaze is still wet; otherwise, they won't stick properly once the glaze has dried completely (you can also pipe designs onto tops using melted chocolate if desired). 
• - Allow glazed doughnuts to sit at room temperature for about 15 minutes before serving so that the glaze has time set up properly.
