These Caramel Apple Crumb Bars begin with a brown sugar oatmeal crust, and they are filled with homemade apple pie filling. These apple pie crumb bars are rich, gooey, and full of caramel apple flavor. An easy fall dessert, but elegant enough for any Thanksgiving table.
Apple pie is the quintessential fall dessert, and is quite possibly the most popular fall dessert (or at least the most popular dessert for the apple season). The rich flavors of brown sugar, cinnamon, and apple have this homey quality about them, as they bring to mind memories of holidays past.
Despite the fact my family has never spent a Thanksgiving holiday without apple pie on the table (we love these apple hand pies, this rustic apple pie recipe, and this cinnamon roll apple pie as well as a classic apple pie), I will be the first to admit a homemade apple pie is a labor of love. Between the chopping and peeling and double pastry crust, it’s a recipe that requires time and energy—no matter how worth the end result is.
These rich and gooey apple crumb bars taste of home—they’re filled with all of the homey, comforting flavors of a classic apple pie—yet they are considerably simpler to make. The oatmeal crumb topping is rich and buttery, reminiscent of oatmeal cookies, and the caramel apple filling is full of warm spices and delicious flavors.
And when topped with a generous drizzle of caramel sauce and vanilla ice cream? Perfection.
Why This Apple Pie Crumb Bars Recipe Works:
Combine the oatmeal crumb with the apple pie filling, and it feels a bit like an oatmeal cookie and a caramel apple pie had a love child. Between the oats and buttery brown sugar, these also feel a bit like apple crisp bars.
- Oatmeal Crumb: I love an easy recipe, and these apple cinnamon crumb bars begin with one dough for both the crust and the topping.
- Apple Filling: The cinnamon apples are a mixture of sugar, cornstarch, and vanilla. It’s the simple flavors that enhance the pure apple flavor.
- Caramel Sauce: Finally, the apple filling is mixed with a homemade brown sugar caramel sauce, which makes these apple bars incredibly rich, gooey, and irresistible. The caramel apples takes this apple dessert to the next level.
Ingredients We Need For These Caramel Apple Crumb Bars:
Making these apple pie bars with crumb topping doesn’t require too many ingredients or steps, especially since the crust and crumble topping are made from the same oat crumb dough.
Crust & Topping:
- Unsalted Butter: Unsalted butter is important because it allows you to control the salt content in the overall recipe.
- Rolled Oats: Rolled oats (also known as old-fashioned oats) work really well in the oatmeal crumb topping, because they are thicker and chewier than quick oats. They give these apple pie bars a lot of texture.
- All Purpose Flour
- Brown Sugar
- Baking Soda
- Ground Cinnamon
- Ground Nutmeg
- Ground Allspice
- Brown Sugar
- Heavy Whipping Cream
- Unsalted Butter
- Vanilla Extract
- Chopped Apples: I prefer a sturdy, sweet type of apple for any apple dessert (think honeycrisp apples, jonagold apples, pink lady apples, gala apples, etc.), but you can also use tart apples, like granny smith apples.
- Vanilla Extract
- Cornstarch: This is an important ingredient because it thickens the apple pie filling.
How To Make These Apple Pie Crumb Bars From Scratch:
I love this recipe because it doesn’t require too much time or energy, yet the apple bars are full of flavor, texture, and spice.
- Caramel Sauce: In a small saucepan over medium heat, whisk brown sugar, heavy cream, butter, salt, and vanilla together. Whisk until boiling, then remove from heat and allow to cool a few minutes while you make the rest of the apple crumb bar recipe.
- Oatmeal Crumb Topping: Using an electric mixer or stand mixer (with the paddle attachment), cream the unsalted butter and brown sugar together until light and fluffy, on medium speed. Next, add in the dry ingredients: rolled oats, flour, baking soda, cinnamon, nutmeg, and allspice. Mix until combined. Set aside.
- Apple Filling: Mix diced apples, vanilla extract, cornstarch, and granulated sugar together. Toss with the caramel sauce. Let the apple mixture sit for five minutes or so.
- Assembly: Press 2/3 of the crust into the bottom of an 8×8 or 9×9 prepared baking pan. Spoon the apple filling on top, spreading into an even layer. Sprinkle the remaining 1/3 of the oatmeal streusel topping on top of the bars.
- Bake: Place the apple bars in the oven and let the bars bake for 30-35 minutes, or until the apple pie filling is bubbling and the top is lightly golden brown.
- Cool: Let the caramel apple bars cool before slicing and serving, otherwise they will fall apart.
- Serve: Serve these apple pie crumb bars with a scoop of vanilla ice cream and an extra caramel drizzle, if desired.
- Room Temperature: These Apple Bars with Oatmeal Crumb Topping can be stored in an airtight container at room temperature for a couple of days.
- Fridge: Or, you can store them in an air-tight container in the fridge for a few days.
How Best To Serve These Apple Cinnamon Crumb Bars?
- Cold: These apple squares are amazing out of the fridge, and can be eaten cold. Top with ice cream, caramel sauce, chopped nuts, etc.
- Room Temperature: These can also be eaten at room temperature, and served similarly with any topping you like.
- Warm: If you prefer a warm apple pie or a warm apple crisp, warm the bars in the microwave and serve a la mode.
- Pro Tip: Want to enhance the depth of flavor even more? Turn these into Salted Caramel Apple Crumb Bars by adding some flaked sea salt on top after they finish baking.

Quick and Easy Caramel Apple Crumble Bars Tips and Tricks:
- Line the Pan: Line the baking dish with parchment paper or non-stick foil. You can simply lift the apple crisp bars out of the pan and cut them.
- Apples: You can use any apple you prefer, and you can choose to leave the apple peels on or off.
- Rolled Oats: Use rolled oats in this apple bar recipe, as the rolled oats add more texture and substance to the oatmeal crumb.
- Caramel Sauce: If you want to top the bars with extra caramel, you can use jarred caramel sauce. Or, you can double the homemade caramel sauce recipe and reserve half of it as a topping. Plus, you can add a bit of flaked sea salt to the sauce to make a salted caramel sauce.
