1 stick butter, melted

Cook first three till apples are partially done in microwave. Combine the rest. Place half of the mixture in a casserole dish, cover with apple mixture & and place other half of oat mixture on top. Bake at 350F covered for about 15 minutes. Remove cover & bake for another 10 minutes or so until top is lightly brown. Usually the apples bubble up & cause the topping to stick together.
