Key Ingredients for Fluffy Custard-Filled Donut Muffins
Simple ingredients, bakery-worthy results
The magic of these fluffy custard-filled donut muffins starts with a handful of familiar, easy-to-find ingredients. But don’t be fooled—they come together to create something seriously next level.
For the Muffin Batter
- All-Purpose Flour: The backbone of the muffin. It gives structure without making them dense.
- Baking Powder: Helps create that light, fluffy lift.
- Butter: Adds richness and keeps the texture tender. Room-temp is key!
- Sugar: Just enough to sweeten, but not overload.
- Eggs: They bind everything and add moisture.
- Buttermilk: The secret weapon. Its acidity activates the baking powder, leading to a softer, moister muffin. (You can DIY it using milk + vinegar!)
For the Custard Filling
- Milk: Whole milk is best for creaminess, but 2% works too.
- Egg Yolks: Give the custard its signature velvety texture.
- Cornstarch: Thickens the custard without making it grainy.
- Vanilla Extract: Essential for that classic pastry cream flavor.
- Sugar: Sweetens the custard just enough without overpowering it.
Step-by-Step Instructions for Custard-Filled Donut Muffins
From batter to bakery-style bliss in a few easy steps
These fluffy custard-filled donut muffins may look fancy, but they’re surprisingly easy to make. Follow these steps, and you’ll be enjoying gooey, golden treats in no time.
🥄 Make the Custard First
In a saucepan, whisk together egg yolks, sugar, cornstarch, and a splash of milk until smooth. Gradually stir in the remaining milk and heat over medium, whisking constantly. Once it thickens into a creamy custard, remove from heat and stir in vanilla extract. Let it cool completely—preferably in the fridge—before filling the muffins.
🧁 Mix the Muffin Batter
In a large bowl, cream together butter and sugar until fluffy. Beat in the eggs, then stir in the buttermilk. In another bowl, whisk the flour and baking powder. Gently fold dry into wet—don’t overmix or your muffins won’t be as tender!
🔥 Bake and Fill
Scoop batter into a greased or lined muffin tin, filling each cup about ¾ full. Bake at 350°F (175°C) for 18–20 minutes or until golden and springy. Let cool slightly.

Frequently Asked Questions About Fluffy Custard-Filled Donut Muffins
Can I make custard-filled donut muffins without a piping bag?
Yes! If you don’t have a piping bag, use a zip-top bag with a corner snipped off. You can also carefully spoon the custard into a hole cut in the muffin center. It’s a bit messier, but still works like a charm.
How do I keep the custard from leaking out?
Let the muffins cool completely before filling them. Warm muffins can cause the custard to melt and ooze out. Also, make sure your custard is fully chilled and thickened. Pipe it right into the center—not too close to the top or bottom.
Can I prepare these muffins ahead of time?
Absolutely. Bake the muffins and store them at room temperature for up to 24 hours. Fill them with custard just before serving, or store filled muffins in the fridge for up to 2 days. Reheat gently to bring back that soft texture—just don’t overheat or the custard might separate.
Is there a shortcut for the custard filling?
Yes! You can use instant vanilla pudding as a quick alternative, but it won’t have the same rich, homemade taste. For best results, stick with a cooked custard—you can follow BBC’s custard guide for tips on how to avoid lumps.
