Preheat oven 325ºF. Grease an 8X8 square pan with butter.
For the crust place flour, oats, brown sugar, salt, baking soda and cinnamon in a bowl and whisk together. Stir in butter and juice until just combined. Will be crumbly.
Reserve ½ cup of crust and press the rest into the bottom of the prepared pan.
For the filling combine all ingredients in a bowl. Spread evenly on top of crust in pan and top with reserved crust. If will not cover cranberries entirely and that's a good thing.
Bake on the middle rack for 40 minutes or until edges turn golden. Allow to cool completely in pan on wire rack before cutting. Drizzle with melted white chocolate for extra sweetness. Enjoy!
