Step 1

Combine the apples, butter, brown sugar, flour, cinnamon, water, and salt in a medium saucepan and place it over medium heat.

Step 2

Stir and allow to cook until apples are softened and sauce is thick, about 10 minutes.

Step 3

Remove from heat and let cool whil you prepare the rest of the ingredients.

Step 4

Preheat the oven to 350 degrees F. Grease a 9-inch x 13-inch baking dish with non-stick cooking spray.

Step 5

Whisk together the flour, oats, brown sugar, baking powder, and salt in a large mixing bowl.

Step 6

Using a fork or pastry cutter, add in the butter and work until well combined. The mixture should have a crumbly texture and sticks together when pinched between your finger tips.

Step 7

Press half of the oat mixture into an even layer in the bottom of the prepared baking dish.

Step 8

Spread the apple pie mixture over the oat mixture and spread evenly in the pan.

Step 9

Sprinkle the remaining oat mixture evenly on top of the apples.

Step 10

Place into the oven and bake for 30 to 40 minutes until golden brown.

Step 11

Remove the baking dihs from the oven and allow to cool completely on a wire rack in the pan. (If you can wait that long.) Then cut into 12 squares and serve. Store any leftovers in an air-tight container.
