Small note - if you do the full recipe, bake it in a jelly roll pan (you know, like 13x26 or however big cookie sheets are), if you half the recipe, a 13x9 works great, and a quarter recipe fits well in a 9x9 pan.
4 oz cream cheese, softened (I microwave it 'cuz that's how I roll)
3/4 c milk
2 T flour
1/4 t salt
Toppings: (or make up your own!)
2 T dijon mustard
1 1/2 c shredded cheddar cheese
1 1/2 c finely chopped ham
1/4 c chopped green onion
Preheat oven to 375. Whisk cream chees & milk until smooth & lump free. Add flour & salt, whisk to combine. In med bowl, whisk eggs then add cream cheese mixture and mix well. Spray pan with non-stick spray and pour egg mixture in. Bake 30-33 minutes (1/2 recipe: 25-28 min, 1/4 recipe: 20-23 minutes) or until puffy & golden. Remove from oven.
Immediately spread with dijon mustard. Sprinkle with cheese, ham & green onion (or other toppings you choose). Let stand for 5 minutes to melt cheese.
