Ingredients
For the Pączki:
• 1 1/2 cups plus 1/4 cup flour, divided
• 1/4 cup sugar
• 1/4 teaspoon salt
• 2 teaspoons yeast (instant or active dry)
• 2/3 cup milk, warmed (about 120°F for instant yeast, 110°F for active dry)
• 3 tablespoons canola oil
• 2 egg yolks
• 1/2 teaspoon vanilla extract
• 1 teaspoon high-proof liquor (optional)
• 2 quarts canola oil for frying
• 1 tablespoon melted butter
• 1/3 cup granulated sugar for coating
For the Custard Filling:
• 1/4 cup sugar
• 1 tablespoon cornstarch
• 1 cup milk
• 1 egg yolk
Instructions
1. Prepare the Dough
In a large bowl, whisk together 1 1/2 cups flour, 1/4 cup sugar, 1/4 teaspoon salt and 2 teaspoons yeast. Gradually add the warmed milk, then mix in the canola oil, egg yolks, vanilla and the optional high-proof liquor. Beat with an electric mixer on high for about 2 minutes until combined.
Add up to the remaining 1/4 cup flour as needed until the dough holds together. Turn the dough onto a floured surface and knead gently—about 50 turns—until smooth. Cover with plastic wrap and let rest for 10 minutes.
2. Make the Custard Filling
While the dough rests, make the custard. In a small saucepan, whisk together 1/4 cup sugar and 1 tablespoon cornstarch. Slowly whisk in 1 cup milk and the 1 egg yolk until smooth. Cook over medium heat, stirring constantly, until the mixture thickens and reaches a boil—about 1 minute. Remove from heat and cool completely; refrigerate if needed so the custard is firm enough to pipe.
3. Shape the Paczki
Line a baking sheet with parchment. Roll the rested dough to roughly 1/2 inch thickness and cut rounds with a 2 1/2-inch cutter. Re-roll scraps as needed. Arrange the rounds on the sheet, cover with a clean towel, and let rise at room temperature for about 1 hour until puffy.
4. Fry the Paczki
Heat 2 quarts canola oil in a large Dutch oven to 360°F. Fry the dough rounds in small batches (2–3 at a time) until golden brown on one side, then flip and brown the other side. Use a slotted spoon or skimmer to transfer paczki to a wire rack to drain. Test the first paczek to confirm it’s cooked through and adjust frying time if necessary.
5. Fill and Coat the Paczki
Fit a pastry bag with a long, narrow tip and fill it with chilled custard. Pipe custard into the center of each paczek until just filled. Lightly brush each side with melted butter, then roll both sides in granulated sugar to coat evenly.
6. Serve
Serve paczki warm or at room temperature for the best texture and flavor. They’re ideal fresh but can be prepared ahead and filled just before serving.
Tips for Perfect Paczki
1. Temperature: Warm the milk to the correct temperature for your yeast type—too hot will kill the yeast, too cool won’t activate it.
2. Gentle Mixing: Combine ingredients until the dough just comes together; overmixing makes dense paczki.
3. Test Fry One: Fry a single paczek first to confirm frying time and oil temperature.
4. Cooling: Let fried paczki cool slightly before filling so the custard won’t run.
5. Custard Texture: The filling should be thick enough to pipe; refrigerate if it’s too soft.

Frequently Asked Questions (FAQs)
1. Can I make paczki in advance?
Yes. You can make and fry paczki a day ahead, storing them in an airtight container at room temperature. Fill them just before serving for best results.
2. What if I don’t have high-proof liquor?
The liquor is optional. It helps reduce oil absorption but can be omitted or substituted with any high-proof spirit if desired.
3. How should I store leftovers?
Store leftover paczki in an airtight container at room temperature for up to 2 days. For longer storage, freeze unfilled paczki and reheat in the oven before filling.
4. Can I use different fillings?
Absolutely. Fruit preserves, chocolate ganache, or cream cheese fillings all work well and offer delicious variations.
5. How do I keep paczki fluffy?
Use the correct amount of yeast, keep ingredients at the right temperatures, and allow sufficient rising time for a light, airy texture.
