Preheat your oven to 325°F
With the "right" (or evenly browned) side down, place 3 Tablespoons of filling in the centre of the crepe
Fold the bottom third of the crepe onto the filling
Roll the crepe over so the seam side is down. Squeeze the crepe gently to push the cheese to the edges and remove any air
Butter a square casserole dish (that has a lid) and arrange four crepes in the dish
Combine ½ cup sour cream with ½ milk and pour a third of it over the bottom crepe layer. Dot with pieces of butter.
Continue with the next layer of 4 filled crepes - but arrange them perpendicular to the first layer. Top with a third of the cream/milk mixture and dot with butter. Repeat with the third layer
Bake in a 325°F oven for 30 minutes or until bubbly. Serve immediately. Smachnoho!
