Preheat oven to 350F. Line a large baking sheet with parchment.
Open crescent roll dough but DO NOT UNROLL. Cut each roll into 4 pieces and place on baking sheet.
Flatten each piece to about 1/2-inch thickness then using your fingers, make a well in the center of each piece leaving a “wall” at the edge, making a nest for the filling. The pieces should resemble a bird’s nest. Brush the edges with the melted butter and sprinkle with sugar.
Beat all the filing ingredients until smooth. Divide equally among prepared rolls.
Bake for 15-18 minutes or until golden brown.
Beat together the icing ingredients. Place in a zippered freezer bag and cut off a small piece at the edge of the bag. Pipe evenly over rolls.
Refrigerated crescent roll dough is not available outside of the US & Canada I am told. I can't recommend a comparable European product, but there are recipes available to make crescents from scratch.
