Apple Lasagna

Preheat oven to 350 degrees F (175 degrees C). Combine Cheddar cheese, ricotta cheese, egg, white sugar, and almond extract in a medium bowl. Blend well. Spread one can apple pie filling over the bottom of a greased 9x13 inch pan. Layer with half of the noodles, and then the cheese mixture. Layer again with remaining noodles, and the second can of pie filling. Combine flour, 6 tablespoons brown sugar, oats, cinnamon, and nutmeg in a small bowl. Cut in butter until crumbly. Sprinkle over top. Bake in preheated oven for 45 minutes. Cool for 15 minutes. Meanwhile, prepare garnish by blending sour cream and 1/3 cup brown sugar in small bowl until smooth. Cover, and refrigerate. Serve warm apple lasagna with sour cream garnish.
