Activate the Yeast:

• In a small bowl, combine the lukewarm milk and 1 tsp of the granulated sugar. Stir in the active dry yeast, cover with a clean towel, and let it sit for 5-10 minutes until it becomes frothy.

Prepare the Dough:

• In a large mixing bowl, whisk together the flour, the remaining sugar, and salt.
• Add the yeast mixture, egg yolks, melted butter, and vanilla extract to the flour mixture. Mix until a dough begins to form.

Knead the Dough:

• Knead the dough for 8-10 minutes until it becomes smooth, elastic, and no longer sticky. If needed, add a small amount of flour (1 tsp at a time).

First Proofing:

• Place the dough in a lightly greased bowl, cover with plastic wrap or a clean towel, and let it rise in a warm area for 1.5 to 2 hours, or until doubled in size.

Portion the Dough:

• Once the dough has risen, punch it down and divide it into 12 equal-sized portions. Roll each portion into a ball and place them on a lightly floured surface.

Second Proofing:

• Cover the rolled dough balls with a clean towel and let them rest for 30 minutes to allow them to proof slightly before frying.

Prepare the Oil for Frying:

• In a large pot, heat vegetable oil to 350°F (175°C). Make sure the oil is hot enough but not overly hot, to ensure even frying.

Fry the Pączki:

• Carefully place each dough ball into the hot oil, frying 3-4 at a time to prevent overcrowding. Fry for 2-3 minutes per side, or until golden brown. Use tongs or a slotted spoon to remove them from the oil and place them on a paper towel to drain excess oil.

Fill the Pączki:

• Allow the fried Pączki to cool slightly before filling. Using a pastry bag with a piping tip or a small spoon, inject each Pączki with your chosen jam or custard filling.

Glaze or Dust with Powdered Sugar:

• Dust the filled Pączki with powdered sugar or drizzle them with icing if desired.

Serve and Enjoy:

• Serve your warm, freshly made Pączki with coffee, tea, or hot cocoa and share them with friends and family
