This recipe is so simple, it’s easy to augment it with nuts, chopped or dried fruit, or different spices.
1/2 C (1 stick) butter
1-1/2 C flour
1 C brown sugar
1-1/2 t baking powder
1 t cinnamon
1/2 t salt
Mix ingredients together in a large bowl. Set aside 1/2 C of this mixture.
To the large bowl, add:
1 egg
1/2 C milk
Pour this mixture into a greased 8×8 pan. (Sometimes, I used a heart-shaped pan as a surprise for my loved one.) Sprinkle the reserved crumb topping over it. Bake at 350 F for 25 minutes, or until done.
