Apple season is starting here in Ontario, and I am so, so ready. We've already gone through a big bag of baking apples that I got less than a week ago... that's how much we like apple desserts here! These apple oat bars have been a huge hit with anyone that has tried them. They taste almost like apple pie, but they are so much easier to make and serve.

'So what exactly are oat bars?' - a question my husband kept asking me as I made him try different versions of this dessert. I think he has a pretty solid understanding now, a couple oat-bar-batches later. In case you were wondering the same thing, I think of oat bars as their own category of dessert, but if I had to compare them to something it would be a pie. They're softer than a cookie, sweeter than a granola bar, but have less filling and are hold their shape better than a pie or crumble.

The secret to making these bars so quick and easy is the bottom crust and the crumble topping is actually the same mixture, which cuts down on the amount of prep work you have to do. Simply mix together the ingredients for the oatmeal crust, pat about 2/3 down onto your greased pan, spread the prepared apples over it, and sprinkle the remaining oatmeal mixture on top. Bake it for about 45 minutes and allow to cool before you dig in! Simple and so addicting! I can't wait to make all kinds of different flavors of oat bars!
