Packzi with a Sweet Sourdough Starter

Have a sourdough starter? You can make Polish Paczki from it! Packzi is a brioche-type donut made with butter, milk, and eggs.
Servings 1.5 dozen


  • 25 grams active sourdough starter
  • 12 grams brown sugar
  • 20 grams warm water
  • 50 grams all-purpose flour
  • 1 cup scalded milk, cooled
  • 2 egg yolks
  • 2 tbsp butter, softened
  • 1/4 cup sugar
  • 1 tsp vanilla
  • 3 cups all-purpose flour
  • 1/2 tsp salt
  • Vegetable Oil for frying
  • Favorite Jam
  • 8 oz cream cheese, softened
  • 1/2 cup powdered sugar
  • 2 tbsp heavy cream
  • 1 tsp vanilla
  • Powdered Sugar


Sourdough Starter Dough

  • Mix active sourdough starter, brown sugar, water, and flour in a small bowl. Knead into a bowl and let sit for several hours, until doubled in size.
  • Once starter dough has doubled in size, add to a stand mixer with paddle attachment. Add cooled, scalded milk, egg yolks, softened butter, sugar, and vanilla. Mix until just combined.
  • Once combined, switch to a dough hook. Add one cup of flour at a time and only right after the cup before is just combined. With the last cup of flour, add 1/2 tsp salt. Mix 4-5 minutes until dough is smooth.
  • Your dough will be soft and pliable but not sticky. Add to another bowl, cover, and let rest 8-12 hours (preferably overnight), until dough is doubled in size once again.

Rolling and Cutting Paczki

  • Lightly flour your work surface. Gently deflate and pull the dough out with your hands.
  • Lightly flour the top before rolling out to a 1/2 inch thickness.
  • Using a 3-inch biscuit cutter, cut into rounds and organize onto a sheet pan with parchment paper.
  • Gently reroll your scraps until you have used all your dough.
  • Cover loosely and let rise about 60 minutes, until puffy.

Frying Dough

  • Heat vegetable oil in deep Dutch Oven to 365-380 degrees.
  • Once oil has reached temperature, fry 4-6 packzi 1-2 minutes per side until golden brown, and then transfer to rack. Continue with remaining paczki. Make sure your oil stays in the frying range. If it drops below 365, heat it back up before adding more paczki.
  • Let packzi cool completely before filling.

Paczki Filling (Jam and Cheesecake)

  • For a jam filling, decide if you want it chunky with fruit or if you want it smooth. If you want it smooth then push jam through a fine mesh strainer to leave out chunks.
  • For cheesecake filling: Cream cream cheese, sugar, heavy cream, and vanilla together until smooth.
  • Once paczki are cooled, use a butter knife to run through center of paczki without going all the way through. Fill a pastry bag fitted with a long tip. Plunge tip into pre-cut paczki and fill gently as you pull out. Stand paczki upright so filling has time to set and does not leak out side.
  • Sprinkle liberally with powdered sugar.


Scalded milk is milk heated to 180 degrees. It helps improve the texture of baked goods, infuse flavors, melt butter and sugar, and reduce the cooking time of sauces.
You can also coat your paczki in cinnamon sugar. Do this right after you remove from frying oil.
