I made this years ago for a Christmas brunch, then promptly lost track of the recipe. Now I've found it again! The recipe is from a B&B website and comes from the Salisbury House B&B in Seattle, WA. Prep time is estimated.
Heat oven to 375* F. Butter and flour a 9x13 inch casserole pan.
To make filling: In a small bowl, beat the cream cheese. Add cottage cheese, 1 egg, 1 tbsp sugar, and vanilla. Beat together and set aside.
To make batter: In a large bowl, cream together butter and 1/3 c sugar. Add the 4 eggs, one at a time, beating well after each addition. Stir in flour and baking powder. Add yogurt, sour cream, and orange juice and mix well.
Pour 1/2 the batter into the casserole. Spread filling over batter. Pour remaining batter over top.
Bake at 375* F for 45-50 minutes or until lightly browned. Cut into squares and serve garnished with dollops of sour cream and preserves.
