Add the eggs, sugar, and salt in a bowl. If using stand mixer, use the whisk attachment and whisk until combined, or use a hand whisk.
2 eggs, 50 grams caster sugar, 1 tablespoon salt
In a separate bowl, mix the warm milk with instant yeast. Make sure the milk isn’t too hot as that will kill the yeast. Add the milk mixture into the eggs and whisk until combined.
10 grams instant yeast, 240 ml warm milk
Add the melted butter and whisk again, then add half the flour and mix until you have a thick batter-like consistency.
170 grams butter melted, 560 grams all-purpose flour
Add the remaining flour and switch to the dough attachment (if using a stand mixer) and knead on medium speed for 5-10 mins until the dough forms a soft ball and starts climbing the dough hook. If not using a stand mixer, start kneading by hand and knead for 10-15 minutes until the dough forms a smooth ball.
Transfer the dough ball to an oiled bowl, cover with cling wrap and let it rest and rise in the fridge for three hours. The dough should double in size during this time. You can also let it rest overnight, for 12-16 hours.
Transfer the dough ball to a floured surface, knead it for 2-3 minutes until smooth, then roll it to 1.5 cm thickness. Make sure that the thickness in even throughout the dough.
Flour the cookie cutter and cut circles out of the dough and place them on baking paper. Tip: cut the baking paper into small square pieces and place each doughnut on a piece. This will make it easier to pick up and transfer the doughnut into the frying pan.
Cover the doughnuts loosely with a towel or cling film and let them rise in a warm place for 30-45 minutes until they double in size. Meanwhile, heat the oil to 170 degrees celsius.
Once the doughnuts have risen and the oil is hot, cook them for 3 minutes on each side until golden brown. To make sure they are cooked through, poke one doughnut with a toothpick or small knife – it should come out clean.
300 ml vegetable oil for frying
Transfer the doughnuts on a paper towel to absorb the excess oil and let them cool down before filling.
