Homemade Boston Cream Donuts with Vanilla Custard and Chocolate Ganache
Classic yeast-raised donuts filled with silky vanilla custard and topped with rich chocolate ganache. These tender, pillowy donuts require patience for the dough to rise twice, but the result is bakery-quality treats with a perfectly crisp exterior and soft interior. The vanilla custard filling is made from scratch using egg yolk and vanilla paste for authentic flavor, while the chocolate ganache provides the signature glossy finish. Perfect for special occasions, weekend baking projects, or when you want to impress guests with homemade pastries that rival any donut shop.

Tips
Ensure milk temperature is around 115 degrees for proper yeast activation - too hot will kill the yeast, too cool won't activate it properly.
Cover custard with plastic wrap touching the surface to prevent a skin from forming while cooling.
Use a thermometer to maintain oil temperature at 350 degrees for even cooking and proper texture.
Good to Know
Store filled donuts covered at room temperature for 1 day or refrigerate for up to 3 days. Ganache may set firmer when cold.
Custard can be made 2 days ahead and refrigerated. Donuts are best fried and filled the day of serving.
Serve at room temperature within a few hours of filling for best texture. Let refrigerated donuts come to room temperature before serving.
Common Mistakes
Don't skip the proofing step - inactive yeast will result in dense donuts that don't rise properly
Maintain oil temperature at 350 degrees to avoid greasy or undercooked donuts
Don't overfill with custard as it can leak out and make donuts soggy
Substitutions
FAQ
Can I make these donuts without a stand mixer?
Yes, you can mix the dough by hand, though it will require more kneading time to develop the gluten for a smooth texture.
What if I don't have vanilla paste?
Substitute with vanilla extract at a 1:1 ratio. Vanilla paste provides more intense flavor and specks, but extract works fine.
How long do these donuts keep fresh?
Best eaten within 24 hours. Store covered at room temperature for 1 day or refrigerate up to 3 days, though texture may change.
