In a large mixing bowl combine flour, sugar, baking powder, salt, and baking soda. Set aside.
In a medium mixing old combine egg, milk, and oil. Add egg mixture all at once to dry mixture. Stir just until moistened.
Add chopped apples and 1/2 teaspoon cinnamon.
Spoon 1/2 of batter into a greased 9 1/4 x5 1/4 inch loaf pan. (*Err on the side of a larger pan if you don't have this exact size.)
In a small bowl combine streusel ingredients; use a fork to blend until mixture resembles large crumbs.
Sprinkle half of streusel over the first 1/2 of batter; add remaining batter and sprinkle remaining streusel over the top.
Bake at 350° for 60-75 minutes, until bread is golden brown and toothpick inserted in center comes out clean. Cool in pan on a wire rack; remove loaf from pan and cool completely.
Combine glaze ingredients and spoon over cooled bread.
