Krapfen (Italian-Style Jam Doughnuts)

Italian-style krapfen are soft, yeast-raised jam doughnuts with a tender enriched crumb and a generous fruit filling. The dough is made with milk, eggs and butter, then scented with lemon zest and vanilla before being proved, cut into rounds and fried until puffed and golden. A coating of caster sugar gives the outside a delicate crunch, while apricot jam brings the familiar bright, slightly tangy centre. They are best served fresh and still soft, making them ideal for a weekend baking project, a festive tray of pastries or a coffee-time treat when you want something more special than a plain doughnut.

Why this recipe works

  • Tender crumb, sugared finish: Milk, eggs and butter enrich the dough, giving the fried doughnuts a soft centre while the caster sugar adds a delicate outer crunch.
  • Balanced bakery flavour: Lemon zest and vanilla lift the buttery dough, while apricot jam brings a bright fruit note without making the filling feel heavy.
  • Proper rise and fry: Two proving stages help the doughnuts puff evenly, and frying at a steady 170°C (340°F) gives colour without leaving the centre undercooked.

Timing notes

  • Let the dough tell you when it is ready: The first rise should double the dough; the second should make the cut rounds visibly puffy. In a cool kitchen this may take longer than expected.
  • Best served fresh: Krapfen have their lightest texture on the day they are fried, ideally while still warm rather than hot.

Texture tips

  • Knead until stretchy: Work the butter in gradually and continue kneading until the dough looks glossy and elastic; this helps create a lighter, more even crumb.
  • Control the frying temperature: Keep the oil close to 170°C (340°F). Oil that is too cool makes the doughnuts greasy, while overheated oil browns the outside too quickly.

Ingredient notes

  • Choose a smooth jam: Apricot jam is classic here because its gentle acidity suits the enriched dough. Warm it just enough to loosen before piping.
  • Use fresh lemon zest: Fresh zest gives a cleaner citrus aroma than dried flavourings and helps cut through the richness of the fried dough.

Make-ahead tips

  • Freeze before filling: For the best texture, freeze the fried doughnuts unfilled, then defrost, warm through and pipe in the jam just before serving.
  • Refresh gently: Reheat briefly in a 160°C (320°F) oven, then roll again in caster sugar if the coating has softened.

  1. Warm the milk until just lukewarm, then stir in the yeast and 1 tsp of the caster sugar. Leave for 5 minutes until lightly foamy.
  2. In a large bowl, mix the flour, salt and the remaining caster sugar. Finely zest the lemon into the bowl, then add the vanilla and eggs.
  3. Pour in the yeasted milk and mix to a shaggy dough, then knead until smooth and elastic. Work in the butter a little at a time and keep kneading until the dough is glossy and stretchy.
  4. Cover and leave the dough to rise in a warm place until doubled in size. It should feel airy and spring back slowly when pressed.
  5. Tip the dough onto a lightly floured surface and roll to about 1.5 cm thick. Cut 12 rounds and place them spaced apart, then cover and leave to prove until puffy.
  6. Heat the sunflower oil in a large pot to 170°C (340°F). Fry the doughnuts in batches for 2 to 3 minutes per side until puffed and deep golden, keeping the oil temperature steady.
  7. Lift out with a slotted spoon and drain briefly, then leave until warm rather than hot. Roll each doughnut in caster sugar to coat.
  8. Warm the apricot jam just enough to loosen it, then spoon into a piping bag. Poke a small hole in the side of each doughnut and pipe in the jam until you feel it plump and heavy.

Recipe notes

Tips

  • Keep the oil at a steady 170°C (340°F): too hot and the outside will brown before the centre cooks, too cool and the doughnuts will turn greasy.
  • If serving to young children, older adults, or anyone who is pregnant or immunocompromised, use eggs that are produced under a food safety scheme and ensure the doughnuts are cooked through.

Substitutions

  • Replace Apricot jam with Raspberry jam for a sharper, fruitier filling.
  • Replace Vanilla extract with Lemon zest for a brighter citrus finish.

Storage

  • Refrigerate up to 2 days
  • Best eaten the day they are made. Store in an airtight container; reheat briefly in a 160°C (320°F) oven for 5 to 7 minutes, then roll again in caster sugar if needed. Freeze unfilled doughnuts, defrost at room temperature, warm in the oven, then fill with apricot jam.
