Fluffy Nutella-filled donuts

Ingredients

• 560 g flour
• 250 ml milk, lukewarm
• 100 g sugar, plus more for rolling
• 4 g yeast
• 40 g butter, soft
• 2 g salt (a pinch)
• A little vanilla, liquid or powdered
• 2 eggs
• Oil, for frying
• Nutella, for filling

Instructions

1. Mix all the dough ingredients with a mixer until smooth and slightly sticky — kneading takes 10 to 15 minutes.
2. Cover and rise until doubled, about 1 hour.
3. Roll the dough 1.5 cm thick, cut rounds, and proof 30 more minutes on squares of parchment.
4. Fry in oil at 170°C (340°F), about 2 minutes per side, until deeply golden. Drain.
5. Roll the warm donuts in sugar, then pipe each one generously full of Nutella.
