Mom's Quick Apple Delight

I know it's not really the season for this kind of desert, but I've been craving apple crisp since my mom made it at Thanksgiving! This is sooooo easy and soooo good!

Ingredients:
2 cans apple pie filling (I will see if I can get my moms homemade recipe for all you from scratch, it's the best!!)
1 white cake mix
3/4 c melted butter
1/2 c brown sugar
1 tbsp cinnamon
1 c chopped walnuts

Directions:
Spread pie filling in greased 9x13 pan. Sprinkle brown sugar and cinnamon over pie filling. Then sprinkle dry cake mix evenly over the top. Drizzle melted butter over cake mix and finish with chopped nuts. Bake at 350* for 40-45 min.
