My mother makes a variation of this recipe. It has less ingredients, but it's delicious! Mom has a preference for MacIntosh apples. As they are the apple of my computer's eye, it's ok by me!
Apple Crisp
Dice 6 or 7 medium sized apples, put in an 8" x 8" pan
Mix following ingredients until crumbly:
1 C. flour
1 1/2 C. sugar
1 egg
1 t. salt
1 t. baking powder
Spread mix over apples, pour 1/2 C. melted butter over all & sprinkle with cinnamon
Bake @ 350 deg. for about 30 minutes
Serve with whipped cream or vanilla ice cream, yummy! Looking at the other recipe, I dunno why you couldn't substitute 1/2 cup of brown sugar for 1/2 cup of white and add vanilla too. If I remember, I will suggest she try it that way next time.
