250 g cold butter
250 g cold cream cheese (Philadelphia)
2 cups flour (250 g)
1 cup Nutella
1 egg (for brushing)
Grate the butter and cream cheese into small pieces
Add flour and form the dough using a food processor/mixer (the dough will be slightly sticky)
Form into a ball, divide into 4 parts
Roll each part into a ball and wrap in plastic wrap
Refrigerate for 30–40 minutes
Roll each dough portion into a circle, about 25 cm in diameter (on a floured surface)
Spread Nutella evenly over each circle
Cut each circle into 12 wedges, like a pizza
Roll each triangle into a rogalik (from wide side to narrow tip)
Bake in a preheated oven at 180°C (350°F) for about 20 minutes
Brush with beaten egg and bake for another 2–3 minutes until lightly glossy and golden
