I was introduced to this recipe many years ago by my friend Marianna Slayter, but over time I have adapted it a little. I eliminated the flour and now I find it eats just as well for dessert or breakfast. You could consider cutting down a little on the sugar, also, depending on how tart you like it.
3/4 cup packed brown sugar
1/2 cup quick or old fashioned oats
1/3 cup butter or margarine, softened
3/4 tsp. ground cinnamon
3/4 tsp. ground nutmeg
Heat oven to 325F. Grease bottom and sides of a square 8×8 pan.
Bake about 30 minutes or until topping is golden brown and apples are tender when pierced with fork. Serve warm, with whipped cream or vanilla yogurt.
Not bad, about 300 calories, not including the whipped cream or yogurt.
