In a mixer, combine the milk, eggs, dry yeast, flour, sugar, honey, and softened butter. Knead until a smooth dough forms. Leave the dough to rise for 30 minutes in a warm place, then transfer it to the refrigerator overnight to rest and rise further.
Day 2:
Divide it into 4 equal portions. Roll out each portion into a rectangle, trimming the edges to form a neat shape. Cut each rectangle into triangles to create the croissant shape. Roll each triangle from the base towards the tip to form a croissant shape. Place the croissants on small baking sheets greased with a little oil. Cover with a towel and let them rise for approximately 1 to 1.5 hours, or until doubled in size.
Heat oil in a deep frying pan or pot over medium heat. Carefully fry the risen croissants in batches for about 3 minutes, or until golden brown. Once fried, transfer the croissants to a paper towel-lined plate to drain excess oil. Fill each croissant with Nutella or your desired filling and sprinkle powdered sugar on top. Serve and enjoy!
RECIPE NOTES
Note: You can also bake the croissants in a preheated oven at 350°F (180°C) for 15-20 minutes instead of frying.
