Ingredients

• 125g / 1 stick unsalted butter, melted: Adds richness and binds the crust; no substitute needed.
• 2 cups (300g) flour, plain/all purpose: Forms the structure of the dough; ensures a sturdy base.
• 1/2 cup (100g) white sugar: Sweetens the base and balances the tartness of the apples.
• 1/2 tsp baking powder: Provides a slight lift to the base for a light, crumbly texture.
• Pinch of salt: Enhances all flavors, balancing the sweetness.
• 1 egg: Binds the mixture, adding cohesiveness to the base.
• 1/3 cup (30g) rolled oats: Adds texture and a subtle nuttiness to the crumble topping.
• 3 – 4 large granny smith apples, cut into 0.7cm / 1/3″ dice (~4 cups): The star ingredient, providing a tart, fruity filling.
• 1/4 cup (35g) plain flour (all purpose flour): Thickens the apple filling, preventing it from becoming watery.
• 1/4 cup (50g) white sugar: Sweetens the apple filling to balance the tartness.
• 1/2 tsp cinnamon: Adds warm, aromatic spice notes to the filling.
• 1/4 tsp nutmeg: Enhances the complexity of the spice profile in the filling.
• Salted caramel sauce: Optional topping for richness and added flavor depth.
• Ice cream: Optional for serving, softens the richness and provides a creamy contrast.

How to Make It

Step 1: Prepare the Oven and Pan

Preheat your oven to 180C/350F. Grease a 20cm/8″ square pan and line it with baking paper, leaving some overhang on the sides for easy lifting. This prevents sticking and makes removal effortless.

Step 2: Create the Crust

In a large bowl, mix together the melted butter, flour, sugar, baking powder, and salt until the mixture is crumbly without visible flour. Add the egg and continue mixing for a cohesive dough. Lightly press 2/3 of this mixture into the prepared pan to create an even layer. It should be firm, but not too compact, as this will form a solid base.

Step 3: Partially Bake the Crust

Bake in the preheated oven for 15 minutes or until slightly golden. This initial bake sets the crust, ensuring it holds together when the filling is added. Let it cool for about 5 minutes.

Step 4: Prepare the Apple Filling

While the crust bakes, combine diced apples, 1/4 cup flour, sugar, cinnamon, and nutmeg in a bowl. Mix until the apples are coated evenly. This mixture creates a thick, jammy filling as it bakes, allowing the spices to infuse the fruit.

Recipe FAQs

Can I use a different type of apple?

Yes, you can substitute other firm, tart apples like Honeycrisp or Pink Lady, but Granny Smith offers the best tartness and texture balance.

Do I have to peel the apples?

Peeling is recommended for a smoother texture. However, leaving the skin on can add extra fiber and color to the bars if you prefer.

How should I store these bars?

Store in an airtight container at room temperature for up to two days. For longer storage, refrigerate for up to a week or freeze for up to three months.
