Coconut Dream Bars

This is my friend Bonnie O’neil’s recipe; it’s so yummy!
1/2 cup brown sugar
3/4 stick butter
1 cup flour

Beat the butter, sugar, and flour together until creamy and spread on an 8-inch square pan. Bake for 15 minutes at 350 degrees

Combine:
1 cup brown sugar
2 eggs
3 tablespoons flour
1/2 teaspoon baking powder
1 cup shredded coconut
1 cup chopped pecans or walnuts 

Spread this mixture on top of baked mix and return to the oven for 15 minutes.
Cut while warm into one-inch squares.
