METHOD

In a medium bowl combine sugar, yeast, and milk and stir to dissolve.
Whisk in egg. Add flour and salt, and start to mix the dough with a spatula. Then continue to knead it with your hands until you receive an elastic dough.

Add softened butter and continue to knead until butter is fully incorporated into the dough.
Form a ball from the dough, cover with a kitchen cloth or plastic wrap, and allow to rise for an hour.
Divide the dough into 8 parts and roll each into a ball. Cover and let sit for 30 minutes.
Flatten each ball a bit and roll it again into a ball. Cover and let sit for another 30 minutes.
Fry balls in hot oil on low for 2-3 minutes on each side.
Let cool a bit and cut in half lengthwise, like a burger bun.
Top one half with whipped cream and chopped strawberries, close with the other half, sprinkle with powdered sugar and serve.
