The most common mistake with these Croatian sugar twist donuts is getting the oil temperature wrong, too low and they soak up grease, too high and the outside burns before the inside sets. This recipe uses a yogurt-enriched dough that’s tender, not bready, and the twisted shape catches the vanilla sugar in every crevice.
The warm water bath proofing gives a reliable rise without a dry skin forming, so the crumb stays soft and evenly airy. If you’ve ever had dense, oily donuts, this sugar twist donut recipe solves both problems with precise proofing and a shape designed for even frying.
I once fried a batch at too low a temperature, and the donuts came out greasy and dense, like soggy sponges instead of light and airy.
Yogurt and Egg Enrichment
Yogurt brings acidity and fat, which tenderizes the gluten network so the crumb stays soft and plush. The egg adds structure and richness, giving the fried dough a satisfying chew without heaviness. Together with the milk, they create a pliable dough that puffs up light and airy in the hot oil.
You taste the richness in every bite, not greasy but distinctly tender.
Warm Water Bath Proofing
Setting the bowl in a warm water bath keeps the dough at a steady 80, 90°F, the sweet spot for yeast activity. No drafts, no dry skin forming on the surface. The flour sprinkled on top absorbs any excess moisture, so the dough rises fully in 30 to 40 minutes without overproofing.
You see the dough double in size, smooth and soft, ready to shape.
Shaping for Sugar and Even Frying
Rectangles with a lengthwise slit, twisted once, create peaks and crevices that hold the sugar coating far better than a plain ring. The twisting ensures even thickness throughout, so every part cooks at the same rate.
That shape also makes it easy to flip with a fork mid-fry. Now I always heat the oil to exactly 350°F and test with a scrap of dough before committing the first batch. The result: a crust that shatters slightly under the sweet coating, with a tender, airy interior.

Key Ingredients for a Tender, Golden Donut
Yeast: Use active dry yeast, not instant; proof it in warm milk until frothy, about 5 minutes.
All-purpose flour: Weigh for accuracy; the recipe uses 560g plus 40g more, divided between dough and dusting.
Plain yogurt: Full fat works best; the acidity and fat tenderize the crumb without making it heavy.
Vanilla sugar: Homemade or store bought; it adds a subtle vanilla aroma that granulated sugar alone won’t.
Working the Dough for a Light Crumb
Proof the yeast
Mix yeast, 1 cup warm milk, and 2 tbsp sugar. Wait until frothy, about 5 minutes. If it doesn’t foam, your milk was too hot or yeast dead, start over.
Mix the base dough
Combine 4 cups flour, yogurt, egg, salt, and 2 tsp vanilla sugar. Add 3 tbsp extra flour and the yeast mixture. Mix on low until shaggy, no dry patches left.
Add warm milk slowly
Heat remaining 1 cup milk until warm to the touch, then stream it in while mixing. The dough will look wet at first; keep mixing 6 to 7 minutes until it pulls away from the bowl and feels smooth.
Warm water proofing
Sprinkle the top with 2 tbsp flour. Set the bowl in a sink or pot half-filled with warm water (bath temperature). Cover and let rise 30 to 40 minutes until doubled and soft.
Knead and roll
Turn dough onto a floured surface and knead 2 minutes, it should be soft and elastic, not sticky. Roll to ½ inch thick. Too thin?
Donuts will be dense. Too thick? They won’t cook through.
Cut and twist
Cut into 2×4 inch rectangles. Slit each lengthwise, leaving one end intact. Twist the two halves a few times and seal the ends.
The twist should hold its shape without unravelling.
Heat oil to 350°F
Fill a pot with 2 inches canola oil and heat to 350°F. Drop in a scrap of dough: it should sizzle and bob to the surface immediately. Too hot?
The outside browns before the inside cooks.
Fry in batches
Gently slide a few donuts into the oil, don’t crowd. Fry 4 minutes total, flipping once with a fork. They should be deep golden brown on both sides, puffed and light.
Drain and coat
Transfer to paper towels to drain for a minute. While still warm, toss in the sugar-vanilla mix. The sugar sticks best when the donut is hot but not greasy.

- 1 tsp vanilla sugar
Instructions
Activate Yeast Mixture:
Mix 2 tbsp yeast, 1 cup warm milk, and 2 tbsp granulated sugar in a small bowl. Let sit until frothy, a few minutes.Combine Dry Ingredients:
In a large bowl, combine 4 cups flour (560g), yogurt, egg, salt, and 2 tsp vanilla sugar. Begin mixing with the dough hook.Add Yeast Mixture:
Add 3 tbsp flour (from the extra 5 tbsp) and the yeast mixture. Mix until incorporated.Incorporate Warm Milk:
Heat the remaining 1 cup milk, then slowly add it to the dough while mixing. Continue for 6-7 minutes until smooth.Let Dough Rise:
Leave the dough in the bowl; sprinkle with the remaining 2 tbsp flour. Set the bowl in a large pot or sink half-filled with warm water. Cover with a clean cloth or paper towel and let rise 30-40 minutes.Knead Dough:
Turn the dough out onto a floured surface and knead by hand for 2 minutes.Shape Donuts:
Roll the dough to ½ inch (1.3 cm) thickness. Cut into rectangles roughly 2 inches by 4 inches (5×10 cm). Slit each rectangle lengthwise, leaving the top intact. Twist and set aside.Heat Frying Oil:
Fill a large pot with canola oil to about 2 inches deep. Heat over medium-high to 350°F (175°C).Fry Donuts:
Gently place a few donuts into the hot oil. Fry for 4 minutes, flipping once with a fork, until golden on both sides.Coat with Sugar:
Remove and drain on paper towels. Toss with a mixture of ½ cup granulated sugar (100g) and 1 tsp vanilla sugar.
Storage and Serving
These donuts are best within a few hours of frying, while the crust is crisp and the interior is tender. For leftovers, store them in a paper bag at room temperature for up to 1 day. A paper bag lets excess moisture escape, so the coating stays dry and the donut doesn’t turn soggy.
Avoid airtight containers; they trap steam and soften the crust. After a day, the texture declines noticeably.
To revive, warm them in a 350°F oven for 3 to 4 minutes, but the crust won’t recapture its original crackle. Do not refrigerate; cold dries them out. Freezing is not recommended because the sugar coating melts unevenly and the texture suffers.
Coat the donuts in sugar immediately after frying while still warm; the sugar adheres best when the surface is hot but not oily. Serve within 2 hours for the best experience.
Tips
- Use a thermometer to maintain oil at 350°F; the scrap test only confirms readiness, not stability. If the oil drops below 325°F when you add the donuts, they will absorb excess oil and turn greasy.
- After twisting, let the shaped donuts rest on the counter for 5 minutes before frying. This relaxes the gluten so they puff evenly rather than shrinking back in the oil.
What You Can Swap in These Sugar Twist Donuts (and What You Really Shouldn’t)
Plain yogurt: Sour cream or buttermilk (same volume). Sour cream gives an identical tender crumb; buttermilk makes the dough slightly looser, so you may need a tablespoon more flour when kneading.
Vanilla sugar: 1 tsp vanilla extract + extra granulated sugar (split the difference: use 2 tbsp extra granulated sugar in the dough and 1 tsp vanilla extract added with the milk). The dough will smell more floral but the crunch coating won’t have vanilla specks, still tasty, just different in appearance.
Canola oil: Vegetable oil, peanut oil, or sunflower oil (same volume). Any neutral oil with a high smoke point works.
Peanut oil adds a faint nuttiness; sunflower oil is neutral. Olive oil will make them taste like bread, not donuts.
All-purpose flour (or yeast): Do not swap. The flour ratio is calculated for a slack dough that puffs properly.
Substituting whole wheat or gluten-free flour will yield dense, heavy donuts. Yeast is important, instant yeast can be used but skip the proofing step and add it directly to the flour, then expect a slightly faster rise.
Frequently Asked Questions
Can I make the dough ahead and fry later?
It’s not ideal. The dough is best proofed and fried the same day. If you must, you can refrigerate the shaped, raw donuts on a floured tray covered with plastic wrap for up to a few hours, but the texture won’t be as airy.
After a day in the fridge, the yeast overproofs and the donuts turn dense. Freezing isn’t recommended, the sugar coating won’t stick properly and the crumb suffers.
Why did my donuts turn out greasy?
Most likely the oil wasn’t hot enough. At 350°F, the crust sets quickly and prevents oil absorption. If your oil temperature dropped below that, especially from overcrowding, the dough soaks up oil.
Check with a scrap of dough first: it should sizzle and float immediately. Also, don’t skimp on draining; let them rest on paper towels for a full minute before coating.
How do these differ from classic American yeast donuts?
The dough is enriched with yogurt and an egg, giving a noticeably more tender, plush crumb compared to a standard brioche-based donut. The shape, a twisted rectangle, creates crevices that hold the sugar coating much better than a plain ring. And the warm water bath proofing ensures a fast, even rise without any dry crust forming, so the interior stays soft and soft.
