6 apples. I like to use 3 granny smiths and 3 gala apples so that it's not too tart.
1/2 C. brown sugar.
3/4 C. flour.
1 C. rolled oats.
a little less than 1/2 C. butter, room temperature. (I found the original recipe a bit too buttery so I took out a few tablespoons of butter. Do as you like.)
2 tsp. cinnamon.
1. peel and core the apples and place into a baking pan. I used a 2.5" 8"x8" pan for this version, but I've also made it in a 9"x13" pan, it just resulted in a much thinner layer of apples and will cook a bit quicker.
2. mix together the sugar, flour, oats and cinnamon.
3. add in the butter in small pieces, cutting it in with a pastry blender or crumbling it in with your fingers, stop when the butter is evenly distributed throughout the mixture, making sure there isn't any large chunks of butter remaining. pour over your apples.
4. bake at 350 degrees for 30 miutes, until the top is brown and crisp and the apples are bubbling. If you're baking in a glass pan remember to turn the temperature down by 25 degrees.
