A Brunch Recipe

I did a cooking class at home for an Enrichment activity a couple of days ago. Despite the fact that my hand mixer died, the class went well. I demonstrated this recipe and it was a big hit.
Ham and Cheese Omelet Roll
4 oz cream cheese, softened
3/4 cup milk
2 Tbsp flour
12 eggs
2 Tbsp Dijon mustard
2-1/4 cups shredded cheddar or Swiss cheese, divided
2 cups finely chopped cooked ham
1/2 cup thinly sliced green onion
Preheat oven to 350. Line the bottom and sides of a greased cookie sheet with parchment paper; grease the paper and set aside. In bowl, beat cream cheese and milk until smooth. Add flour and salt; mix until combined. In bowl beat eggs until blended. Add cream cheese mixture; mix well. Pour into greased pan. Bake for 30 minutes or until eggs are puffed and set. Remove from oven. Immediately spread with mustard and sprinkle with 1 cup cheese. Sprinkle with ham, onions, and 1 cup cheese. Roll up from a short side, peeling parchment paper away while rolling. Sprinkle top of roll with the remaining cheese. Bake 3-4 minutes or until cheese is melted.
