Gently melt the butter over low-medium heat. Add milk and 2 tablespoons of sunflower oil and mix together.
Once combined, take off the heat and set aside.
In a separate bowl, combine the flour, half of the sugar, baking powder, and salt with a fork.
Make a well in the center and pour in the butter mixture. Combine gradually until a thick dough forms.
Using your hands, roll dough into little flat balls and with your thumb, press a hole in the center of each doughnut. (You may need to flour your hands for this part to avoid getting sticky!)
Heat up oil in a pan. To know when it's hot enough, fry a little bit of bread in the oil. If it goes brown and floats to the top, in 45-50 seconds the oil will be ready!
Gently lay the doughnuts into the oil using a spatula. Fry for about 3-5 minutes on each side, until golden brown.
Transfer the doughnuts onto some tissue paper to soak up any excess oil.
Roll the doughnut into a bowl of the remaining half of sugar or sugar glace (mix sugar powder with a splash of plant milk and mix)
Decorate and enjoy.
