Apple cinnamon oatmeal bars have an oatmeal crumb base, soft cinnamon apple centre, and a crumb top. It tasted just like an apple crisp!
I love these bars because they make a perfect snack or quick on the go breakfast. They easy to make, taste amazing, and are a perfect way to use up those apple sitting in your fridge.
WHY YOU’LL LOVE THESE BARS
Easy to Make– The recipe comes together so easily and is mixed by hand.
Basic Ingredients – The recipe uses common household ingredients so no need to make a large expensive grocery store trip.
Amazing texture- It has a chewy oatmeal cookie like base, soft apple cinnamon in the middle, and topped with a crunchy crumble.
They taste so good- They taste just like apple crisp. We all know the best part of apple crips is the oat crumble, these bars have a base and topping made out of the ingredients.

HOW TO MAKE Apple Cinnamon Oatmeal BARS
Preheat oven to 375F and line a square 9×9 baking pan with parchment paper.
Peel and thinly slice your apples and set aside in a medium sized mixing bowl.
Crumb Base/Topping
In a large bowl whisk together the rolled oats, brown sugar, flour, and cinnamon. Next, add the melted butter into the dry ingredients and mix till everything is combined. It will have crumbly texture.
Set aside 1/2 C of the crumb mixture and pour the rest into your pan. Then, evenly press the crumb mixture down with your hands to form a solid crust.

To the sliced apples add in the white sugar, cornstarch, cinnamon, and lemon juice. Mix well to coat all the apple slices. Spread the apple mixture over the crumb base in your pan.

Top with the remaining 1/2 of crumb mixture you set aside. You just want to sprinkle it above the apples.

Bake for 28 minutes or the edges are golden brown. Let fully cool to room temperature in the pan before cutting into bars.

Can I Eat Them Warm?
It is important to let the bars fully cool in the pan to room temperature before removing them and slicing. The bars need time to stiffen up. If you try and slice them before they cool they'll fall apart.
WHAT TYPE OF APPLES SHOULD I USE?
You can you any type of apple you like! I have made it with baking apples and non baking apples it it works great with both varieties. The latest version (the one I made for the process photos) I used MacIntosh apples.
HOW TO STORE THE BARS
These bars are best served on the day they're made. Bars should be stored in an airtight container at room temperature. If stored properly the bars keep well for three days. They still taste amazing days after baking, but the topping will start to soften.
