These Apple Crisp Bars are like a warm hug with sweet apples and crunchy toppings! They are easy to grab and eat, perfect for snacks or dessert.

Key Ingredients & Substitutions
Apples: Granny Smith apples are tart and hold their shape well when baked, making them ideal for this recipe. You might substitute with Honeycrisp or Braeburn for a sweeter taste, or mix sweet and tart apples for depth of flavor.
Butter: Unsalted butter gives you control over the saltiness. If you need a dairy-free option, try using coconut oil or a plant-based butter that works for baking.
Oats: Old-fashioned rolled oats are best for texture. Quick oats can work, but they might make the topping less crunchy. For gluten-free options, use certified gluten-free oats.
Brown Sugar: Light brown sugar adds sweetness and moisture but can be substituted with white sugar or a sugar alternative like coconut sugar. Keep in mind that it may slightly change the flavor and texture.
How Do I Ensure My Apple Filling Is Perfectly Sweet and Spiced?
Balancing the sweetness and spices in your apple filling is key to a great flavor. Here’s how you can achieve this:
- Use a mix of apples for varied taste and texture; combining sweet and tart apples gives a lovely balance.
- Add lemon juice to brighten the flavor and prevent browning in apples. It enhances the overall taste!
- Adjust sugar based on your apple’s natural sweetness; taste your mixture before adding more sugar.
- Don’t skip the spices! Cinnamon, nutmeg, or allspice can elevate your filling, making it warm and cozy.
Using fresh, quality ingredients and tasting as you go can make all the difference in your Apple Crisp Bars!

How to Make Delicious Apple Crisp Bars
Ingredients You’ll Need:
For the Crust and Crumble Topping:
- 2 cups all-purpose flour
- 1 ½ cups old-fashioned rolled oats
- 1 cup light brown sugar, packed
- 1 teaspoon ground cinnamon
- ½ teaspoon salt
- 1 cup (2 sticks) unsalted butter, cold and cut into cubes
For the Apple Filling:
- 5 cups peeled, cored, and finely chopped apples (about 5 medium apples; use a tart variety like Granny Smith)
- ½ cup granulated sugar
- 2 tablespoons all-purpose flour
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- 1 teaspoon fresh lemon juice
How Much Time Will You Need?
This recipe will take about 15 minutes to prep and 45-50 minutes to bake, plus some time to cool down. In total, you should set aside about 1 hour and 10 minutes to make and enjoy these delectable Apple Crisp Bars.
Step-by-Step Instructions:
1. Preheat Your Oven and Prepare the Pan:
Start by preheating your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving a bit of overhang on the sides. This makes it easier to lift the bars out later!
2. Make the Crust and Topping:
In a large bowl, combine the flour, oats, brown sugar, cinnamon, and salt. Toss them together. Then, add the cold butter cubes. Use a pastry cutter or your fingertips to mix everything until it looks like coarse crumbs. Some should be the size of peas, which will add nice texture!
3. Form the Crust:
Take about two-thirds of the crumb mixture and press it firmly into the bottom of the prepared pan, creating a nice, even crust. Set the leftover crumb mixture aside for topping.
4. Prepare the Apple Filling:
In a medium bowl, mix the chopped apples with granulated sugar, flour, cinnamon, nutmeg, and lemon juice. Ensure everything is well combined so you get even sweetness and spice!
5. Assemble the Bars:
Spread the apple filling evenly on top of the crust in the pan. Then, sprinkle the reserved crumb mixture evenly over the apple layer.
6. Bake:
Place the pan in the preheated oven and bake for 45-50 minutes or until the top is golden brown and the filling is bubbling a little.
7. Cool and Cut:
Once done, remove the pan from the oven and let the bars cool completely in the pan on a wire rack. This cooling step helps the filling set properly.
8. Serve and Enjoy:
Once cooled, use the parchment overhang to lift the bars out of the pan. Cut them into squares and serve. You can enjoy them plain or warm with a scoop of vanilla ice cream or a drizzle of caramel sauce for a delightful treat!
These Apple Crisp Bars are comforting and delicious with their buttery oat crust and spiced apple filling—a perfect addition to your autumn dessert menu!

Can I Use a Different Type of Apple?
Absolutely! While Granny Smith apples are ideal for their tartness and firmness, you can also use other varieties like Honeycrisp, Braeburn, or a mix of sweet and tart apples for added flavor and texture.
Can I Make These Bars Gluten-Free?
Yes! To make these bars gluten-free, simply substitute the all-purpose flour with a gluten-free flour blend and ensure your oats are certified gluten-free. The texture may vary slightly, but they will still be delicious!
How Should I Store Leftovers?
Store any leftovers in an airtight container at room temperature for up to 3 days. For longer shelf life, you can refrigerate them for up to a week or freeze for up to 3 months. Just let them cool completely before freezing!
Can I Add Nuts or Other Ingredients?
Definitely! Feel free to mix in some chopped nuts, like pecans or walnuts, for added crunch. You can also add raisins or cranberries for a fruity twist. Just be sure to adjust the quantities to maintain the overall balance of the bars.
