What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Here’s what you’ll need:

• For the crust:
• 1 ½ cups (190g) all-purpose flour
• ½ cup (100g) granulated sugar
• ½ teaspoon baking powder
• ¼ teaspoon salt
• ½ cup (115g) unsalted butter, cold and cubed
• 1 large egg, lightly beaten
• For the apple filling:
• 4 medium apples, peeled, cored, and thinly sliced (I love using Granny Smith for their tartness)
• ¼ cup (50g) granulated sugar
• 2 tablespoons (15g) all-purpose flour
• ½ teaspoon ground cinnamon
• ¼ teaspoon ground nutmeg
• 1 teaspoon lemon juice
• For the streusel topping:
• ¾ cup (95g) all-purpose flour
• ½ cup (100g) brown sugar, packed
• ½ teaspoon ground cinnamon
• ¼ teaspoon salt
• ½ cup (115g) unsalted butter, melted

If you’re missing anything, don’t worry! You can substitute pears for apples, use dairy-free butter for a vegan option, or swap brown sugar for coconut sugar—it’s as flexible as it is delicious.

Equipment Needed

• 9×13-inch baking pan (a glass or ceramic one works best for even baking)
• Mixing bowls (at least three for the crust, filling, and topping)
• Pastry cutter or fork (for blending the butter into the crust mixture)
• Peeler and corer (to prep the apples quickly)
• Wire rack (for cooling the bars evenly)

If you don’t have a pastry cutter, no problem—a fork or even your fingers will do the trick. And if you’re in a pinch, a square baking pan can work instead of a 9×13-inch one—just adjust the baking time slightly.

Preparation Method

1. Preheat your oven: Set your oven to 350°F (175°C) and grease your 9×13-inch pan with butter or non-stick spray.
2. Make the crust: In a mixing bowl, whisk together the flour, sugar, baking powder, and salt. Add the cold, cubed butter and cut it into the dry ingredients using a pastry cutter or fork until the mixture resembles coarse crumbs. Stir in the beaten egg until the dough starts to come together. Press the dough evenly into the bottom of your prepared pan.
3. Prepare the apple filling: In another bowl, toss the sliced apples with sugar, flour, cinnamon, nutmeg, and lemon juice until evenly coated. Spread the apple mixture over the crust in an even layer.
4. Make the streusel topping: Combine the flour, brown sugar, cinnamon, and salt in a bowl. Pour in the melted butter and stir until the mixture forms clumps. Sprinkle the streusel evenly over the apple filling.
5. Bake: Place the pan in the oven and bake for 40-45 minutes, or until the topping is golden brown and the apples are tender. Your kitchen will smell heavenly!
6. Cool: Let the bars cool completely on a wire rack before slicing. This helps them set and makes cutting easier.

Pro tip: If your streusel looks too dry, add a little more melted butter until it clumps nicely. And don’t forget to let the bars cool fully—trust me, it’s worth the wait!

Cooking Tips & Techniques

• Use firm apples for the best texture. Softer varieties like Red Delicious may turn mushy during baking.
• Keep your butter cold when making the crust—this helps create a flaky base.
• Don’t overmix the streusel topping; you want clumps for that perfect crumbly texture.
• If your apples are extra juicy, sprinkle a bit more flour to prevent a soggy crust.
• For a glossy finish, brush the apple layer with a bit of melted butter before adding the streusel.

One time, I rushed and didn’t cool the bars properly—big mistake! They fell apart when I tried to slice them. Patience really is key here.

Variations & Adaptations

• Gluten-Free: Swap out the all-purpose flour for a gluten-free baking blend.
• Vegan-Friendly: Use plant-based butter and a flaxseed egg substitute.
• Seasonal Twist: Try pears or even peaches instead of apples for a summery vibe.
• Nutty Streusel: Add chopped pecans or walnuts to the topping for extra crunch.
• Spice It Up: Experiment with cardamom or ginger for a unique flavor profile.

One of my favorite variations is swapping the apples for mixed berries in summer—it’s just as delightful and perfect with a scoop of vanilla ice cream.

Serving & Storage Suggestions

Serve these bars slightly warm or at room temperature for the best flavor. Pair them with a dollop of whipped cream or a scoop of vanilla ice cream for an indulgent dessert. They also make a lovely afternoon snack alongside a cup of coffee or tea.

To store, cover the bars tightly and keep them in the refrigerator for up to 5 days. If you want to freeze them, wrap individual bars in plastic wrap and store them in an airtight container for up to 3 months. To reheat, pop them in the microwave for 15-20 seconds or warm them in the oven at 300°F (150°C) for 10 minutes.

Nutritional Information & Benefits

FAQs

Can I use store-bought apple pie filling?

Granny Smith apples are my favorite for their tart flavor and firm texture, but Honeycrisp or Fuji work well too.

Can I make these bars ahead of time?

Absolutely! They store beautifully in the fridge for up to 5 days or in the freezer for 3 months.

How do I prevent a soggy crust?

Make sure to use firm apples and toss them with flour before layering them over the crust. This helps absorb excess moisture.
