My version of “apple brownie”

1 cup (2 sticks) unsalted butter, melted
1  cup brown sugar  (next time can do even less)
2 eggs
1 teaspoon vanilla 
3 cups apples (about 2-3 apples), peeled, cored and chopped
½ cup chopped walnuts

1 cup of whole spelt flour

1 cup white rice flour

2 teaspoon cinnamon
1 teaspoon baking soda
1 teaspoon baking powder
½ teaspoon salt

sift dry ingredients together

mix in dry into wet and mix just to moisten, bake on 375 F for about an hour
