Ingredients You’ll Need
These ingredients are simple staples that come together beautifully for the perfect texture and flavor. Each one plays a special role in making your Apple Crumb Bars Recipe taste just right – from the tangy apples that bring bright flavor to the rich, buttery crumbs that cradle them.
- 3 cups all-purpose flour: The foundation of the crumbly crust and topping, giving structure without heaviness.
- 1 cup granulated sugar: Adds sweetness and helps with browning for a golden finish.
- 1 teaspoon baking powder: Ensures the crumb topping is light and tender, not dense.
- 1/4 teaspoon salt: Balances flavors and enhances sweetness.
- 1/4 teaspoon ground cinnamon: Brings warmth and spice, perfectly complementing the apples.
- 1 cup unsalted butter, chilled and cut into cubes: The secret to that melt-in-your-mouth crumbly texture.
- 1 large egg: Helps bind the crust together for easy pressing and perfect crumb consistency.
- 5 medium-sized apples, peeled, cored, and diced: The star ingredient, bursting with fresh, juicy flavor.
- 1/2 cup packed light brown sugar: Adds caramel notes and sweetness to the apple filling.
- 2 tablespoons cornstarch: Thickens the juicy apple filling so it’s not runny.
- 1 tablespoon lemon juice: Keeps the apples bright and fresh-tasting, preventing browning.
- 1/2 teaspoon vanilla extract: Adds subtle depth and enhances the overall flavors.
How to Make Apple Crumb Bars Recipe
Step 1: Prep Your Baking Dish and Oven
Get your oven warming up to 375°F (190°C). Preparing your 9×13-inch baking dish by greasing it or lining with parchment ensures a smooth release for those perfect bars once they’re baked and cooled.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, whisk together flour, granulated sugar, baking powder, salt, and cinnamon. This well-blended combination forms the base flavor and texture of your crumb layers, giving just the right hint of spice.
Step 3: Incorporate Butter and Egg
Add the chilled butter cubes and egg to your dry mix. Now the fun begins! Use a pastry cutter or your hands to gently crumble everything until it looks like coarse crumbs. This step is key to that signature crumbly texture that melts in your mouth.
Step 4: Press Half the Crumb Mixture for the Crust
Take half of your crumbly mixture and press it firmly and evenly into the bottom of your prepared pan. This will be the firm, buttery crust that holds the flavorful apple filling, so make sure it’s even and packed down.
Step 5: Mix the Apple Filling
In a separate bowl, toss together diced apples, brown sugar, cornstarch, lemon juice, and vanilla extract. This luscious apple mix is the heart of your bars, with each ingredient brightening and blending the flavors while the cornstarch thickens all that apple juice.
Step 6: Spread the Apple Mixture Over the Crust
Evenly distribute the apple filling on top of your pressed crust layer. You want a generous, uniform layer of apples so every bite has that perfect balance between fruit and crumb.
Step 7: Top with Remaining Crumb Mixture
Sprinkle the rest of the crumb mixture evenly over the apples, gently pressing down. This final layer seals in the fruit and adds that irresistible golden crunch on top when baked.
Step 8: Bake Until Golden and Bubbly
Slide your pan into the oven and bake for 40 to 45 minutes. You’ll know it’s done when the top is golden brown and you see the apples bubbling happily beneath the crumb topping.
Step 9: Cool, Cut, and Enjoy
Let the bars cool completely on a wire rack right in the pan. This step helps the filling to set, so you get clean slices every time. Once cooled, cut into squares and get ready to delight your taste buds!

FAQs
Can I use different types of apples for this recipe?
Absolutely! Feel free to mix tart and sweet apples like Granny Smith and Fuji for a more complex flavor. Just make sure the apples you choose are firm so they hold up well while baking.
Is it possible to make this recipe gluten-free?
Yes! Substitute the all-purpose flour with a gluten-free baking mix that measures cup-for-cup. Keep in mind that the texture may vary slightly but will still be delicious.
