This is the most Easy Apple Crumble recipe that I came across from Irene's blog. Not only is it easy, it's also very yummy and addictive too. I used organic rolled oats that I had on my pantry (you can use any type of oatmeal that you have). Though the crumble wasn't very crispy and golden brown after baked but it served as a comforting oaty apple snack. The crunch of the warm apple and crumble tasted so good, I couldn't resist going for second helping.
