1/2 cup melted butter
1 cup brown sugar (packed)
1/4 cup milk
1 1/4 cup flour
1/2 tsp salt
1/2 cup chopped white chocolate (I used Lindt Swiss White Chocolate)
1/4 cup semi sweet chocolate chips
1 cup blueberry pie filling
Preheat oven to 350°. Spray a 2L/2.2Q rectangular baking dish with non-stick cooking spray.
Combine melted butter and brown sugar in mixing bowl and mix until well blended. Add egg and beat well. Add milk and vanilla and mix well.
Spread mixture into prepared baking dish.
Top with blueberry pie filling, gently spreading evenly (careful not to disturb bottom layer).
Bake at 350° for 40-45 min until toothpick inserted in the centre comes out clean.
Allow to cool. Cut into 32 bars. Devour!
