Oil an 8" by 8" cake pan. Preheat oven to 375 degrees.
Biscuit Mix: Add flour, baking powder, baking soda and sugar to medium bowl. Stir dry ingredients and combine well. Cut cold butter to pats then slice and cube. Incorporate butter 1/2 at a time. I use a multi-blade hand pastry blender to do this. Combine rest of butter until mixtures is crumbly. Slowly add in 1/3 cup cold water a little at a time. Don't over mix.
Apple Pie Filling: In separate bowl add the 2/3 cup Brown Sugar and 1/2 teaspoon Cinnamon to the Apple Pie filling. Stir well.
Add 1/2 the pie filling to pan. Then top with 1/2 the biscuit mix. Just dump it around. Then add remaining apples followed by remaining biscuit mix.
Top with three pats of Butter and a sprinkle of Cinnamon and Sugar. Bake for 40 minutes at 375 degrees, reduce heat to 325 degrees for another 10 to 15 minutes.
