Ive made these for the past 2 weekends, and they came out so yummy!

2 cups of Bisquick
1 apple, diced
1/3 cup sugar
1 tbsp oil
1 egg
a handful of walnuts - as much or as little as you want

Mix all this up. I've added milk if it looks too dry. This makes about 9 big muffins.
Bake for 15 - 19 min at 400 degrees
