Soft, fluffy Polish donuts made from grandma’s recipe
There’s something magical about traditional Polish oponki — soft, fluffy donuts made with white cheese (quark/twaróg), lightly crispy on the outside and tender on the inside. For many of us, they bring back memories of grandma’s kitchen, the smell of frying donuts, and powdered sugar floating in the air.
The problem? Traditional recipes often require long kneading, sticky dough, and a lot of manual work. Many people also struggle to get the right dough consistency — either too soft to roll or too dense and heavy.
That’s where Thermomix comes in. This recipe transforms a classic grandma-style donut into a quick, foolproof, and perfectly mixed dough in just minutes. No stress, no mess — just perfect Polish oponki every time.

FAQs
Can I make these without Thermomix?Yes! You can mix and knead by hand or with a stand mixer, but Thermomix makes it faster and more consistent. What cheese can I use instead of twaróg?
Farmer’s cheese, quark, ricotta (well-drained), or blended cottage cheese work well. Why are my donuts not fluffy?
The dough may be too dense — try adding a bit more sour cream or reducing flour slightly.
