Making the Crust

The first thing you will want to do for this recipe is to make the crust. While the crust is baking, you can prepare the rest of the layers that will go in and be baked all together to make the bars.

In a large bowl, blend the flour, confectioners’ sugar, and butter. I like to use my hands to mix these three ingredients together, but you can also use a blender or pastry cutter. Make sure the ingredients are well incorporated with the butter being no bigger than the size of a pea.

Once the ingredients have been mixed, press the mixture into an 8×8 inch greased pan. Bake for 15 minutes at 325°F, or just until the edges are starting to turn golden. As the crust is baking, prepare the apple filling, caramel layer, and crumble topping.

How to Make the Apple Filling

Get started by peeling, coring, and slicing your apples. For this recipe, slice the apples on the thinner side.  In a bowl, combine the sliced apples with the brown sugar and flour. I used Granny Smith apples for the recipe because they remain firm when baking. They won’t turn to mush and they tend to retain their shape when baked. A few other options you could try would be Honeycrisp apples, Braeburn, or Pink Lady apples.

Caramel Layer

For the caramel layer that will go over the apple filling, simply combine the caramel topping with the flour in a small bowl. This is the layer that will give you that ooey-gooeyness that you will get with each yummy bite!

Oatmeal Crumble Topping

The butter should be cold and cut into small cubes for this crumble topping, just like with the crust. Add all the ingredients to a bowl and using a fork or your hands (I prefer hands, and often let the kids help out with this step) and combine all ingredients, making sure the butter is broken down and no larger than a pea when you are done. That’s it!

Assembling the Oatmeal Caramel Apple Bars

After the crust has baked for 15 minutes, remove it from the oven, but leave the oven on.

  1. Pour the apple mixture over the crust.
  2. Next, pour the caramel layer over the apples.
  3. Top it off with the crumble mixture.
  4. Bake for another 35 minutes.

Serve with some caramel drizzle and whipped cream! Ice cream would be great on these dessert bars as well. Store them in an airtight container at room temperature for up to 3 days or the refrigerator for up to 5 days. You could also freeze them; they will last up to 3 months in the freezer. Remember to label and date the container.
