1/4 C light brown sugar, packed
1 tbsp fancy molasses
3/4 C sour cream

Preheat oven to 325 degrees F.

Grease a 9x9 inch baking pan and line the bottom with parchment paper.

Beat butter, sugar, and brown sugar until smooth. Stir in molasses, sour cream and 1/2 C apple butter. Stir in yolks and egg.

In a separate bowl sift pastry flour, whole wheat flour, cinnamon, nutmeg, baking powder, baking soda and salt and gently stir into wet ingredients. Fold in oats.
