Spray a 9 x 13-inch glass baking dish with nonstick spray. (You can also use two 9-inch pie plates.) Use a food processor fitted with the steel blade to process all ingredients.

Combine all ingredients and blend until smooth, about 30 seconds, scraping down sides of bowl once or twice.

Transfer batter to a 4 cup measuring cup or bowl. (Don’t bother washing processor bowl. Just scrape it out well with a spatula.)

Process ricotta cheese and cream cheese until smooth, about 30 seconds. Add remaining filling ingredients and process 30 seconds longer.

Pour half the batter into prepared dish. Spoon filling overtop, gently spreading without mixing it into the batter. Pour remaining batter over filling.

Bake in preheated 300-degrees-Fahrenheit oven about an hour and a half, until set and nicely browned. (If baked in two pie plates, baking time is about one and a quarter hours.)
