These cinnamon apple crumb bars capture everything I love about classic apple pie but make it easier and totally portable. Each buttery square has a melt-in-your-mouth shortbread crust, a layer of spiced apples, and a golden oat crumble on top. You get a cozy dessert perfect for chilly afternoons, family gatherings, or packed lunches all fall and winter.
I made these on a whim when I had leftover apples in late October. Now every time the weather cools I get requests from friends and family—they disappear fast whenever I bring a batch to a gettogether.
Ingredients
- Unsalted butter: Soft creamy butter gives richness and a delicate base and helps the crumb topping hold together Use a quality butter for best flavor
- Brown sugar: Adds a deep caramel note and keeps both crust and topping moist Choose fresh soft brown sugar
- Allpurpose flour: Ensures tenderness and structure through each layer Select unbleached if possible for superior texture
- Salt: Enhances flavor and balances the sweetness Use fine sea salt if you have it
- Apples: Granny Smith or Honeycrisp hold their shape and give the best tartsweet balance Pick firm fruit with no bruises
- Granulated sugar: Sweetens the apple filling without overpowering the spices Choose pure cane sugar
- Ground cinnamon: Brings out the apple flavor and adds that warm cozy scent Use fresh ground
- Ground nutmeg: Provides complexity and a touch of autumn warmth Freshly grated if possible is fantastic
- Fresh lemon juice: Keeps apples bright and prevents browning Use juice from a firm lemon
- Oldfashioned oats: Add heartiness and golden crunch to the topping Go for thickcut rolled oats
Instructions
- Prepare the Baking Pan:
- Preheat your oven to 350°F or 175°C and line a 9 by 13 inch pan with parchment paper, leaving extra over the edges for easy lifting later This ensures the bars release cleanly after baking
- Make the Shortbread Base:
- Cream the softened butter and brown sugar together in a mixing bowl using an electric mixer on medium speed for about 2 to 3 minutes This will look fluffy and pale Mix in the allpurpose flour and salt just until a soft dough forms Do not overmix as that keeps the crust tender Firmly press the dough into an even layer in the bottom of your lined pan Make sure there are no gaps or thin spots Bake the crust for 15 minutes until it’s just beginning to turn golden This bakes it enough to stay crisp when you add the juicy apple layer
- Prepare the Apple Filling:
- While the base bakes dice your apples into small even pieces to ensure an even bake Toss them in a large bowl with the granulated sugar allpurpose flour ground cinnamon ground nutmeg and fresh lemon juice Stir well so every apple cube is coated The flour thickens the filling as it bakes to avoid watery bars
- Make the Crumb Topping:
- In another bowl mix the allpurpose flour brown sugar and cinnamon together Use your fingers or a pastry blender to cut in the cold cubed butter until the mixture looks like coarse breadcrumbs Finally stir in the oldfashioned oats for crunch and rustic texture The key is keeping the butter cold so the topping bakes up crispy
- Assemble and Bake:
- When the crust comes out of the oven scatter the coated apples evenly over the hot base so every bite will have fruit Sprinkle the crumb topping generously over the apples covering as much of the fruit as possible Bake for 25 to 30 minutes until the topping is deep golden and you can see apple juices bubbling at the sides
- Cool and Serve:
- Let the pan cool completely on a wire rack The bars firm up as they cool making them easy to cut and handle Use the parchment paper to lift the whole block from the pan Slice into 16 equal bars and serve as is or top with ice cream for an extra treat

I have never met anyone who does not reach for seconds with these bars My favorite part is the way cinnamon and brown sugar caramelize around the apple chunks in the middle I remember making these with my mom one crisp Thanksgiving morning and sneaking warm pieces before the guests arrived
