These brown butter apple shortbread bars are rich, cozy, and packed with warm fall flavor. With a buttery shortbread base, a tender spiced apple filling, and a crumbly topping, they deliver all the comfort of apple pie in a much simpler, slice-and-serve form.

Why You’ll Love This Recipe

Brown butter adds deep, nutty richness that makes these bars taste bakery-worthy. The apples bake into a soft, jammy layer that balances sweetness with a subtle tart bite. Unlike traditional apple pie, there’s no rolling or chilling pie dough, making this recipe far easier while still delivering impressive flavor and texture.

The shortbread crust is sturdy yet tender, the filling is perfectly spiced, and the crumb topping bakes to golden perfection. These bars are ideal for gatherings, potlucks, or make-ahead desserts because they slice cleanly and travel well.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the shortbread:

1 1/2 sticks (3/4 cup or 170 g) unsalted butter, cut into 12 pieces
3/4 teaspoon kosher salt
2 cups (250 g) all-purpose flour
1/3 cup (67 g) granulated sugar
1/3 cup (73 g) packed light brown sugar
3/4 teaspoon baking powder

For the apple filling:

2 large eggs
1/3 cup (67 g) granulated sugar
1/3 cup (73 g) packed light brown sugar
2 tablespoons (16 g) all-purpose flour
2 tablespoons (30 ml) heavy cream
1 teaspoon apple pie spice
1/4 teaspoon kosher salt
1 1/4 pounds (about 570 g) tart and sweet-tart apples such as Granny Smith, Fuji, Pink Lady, or Gala, peeled, cored, and sliced 1/8-inch thick

Directions

Preheat the oven to 350°F (175°C).

To brown the butter, melt the 1 1/2 sticks of unsalted butter in a light-colored saucepan over medium heat. Stir frequently, scraping the bottom of the pan. The butter will foam and begin to smell nutty as the milk solids turn deep golden brown, about 8 to 10 minutes. Remove from heat and immediately stir in 3/4 teaspoon kosher salt. Transfer to a heatproof bowl and let cool slightly.

Line an 8×8-inch baking pan with two sheets of parchment paper arranged perpendicular to each other, leaving overhang on all sides to create a sling.

In a large bowl, whisk together the flour, granulated sugar, light brown sugar, and baking powder. Slowly pour the browned butter into the dry ingredients while stirring with a spatula until a crumbly dough forms.

Reserve 3/4 cup of the dough for the topping. Press the remaining dough evenly into the prepared pan to form the crust.

Bake for 15 minutes, or until lightly golden and set. Remove from the oven and place on a wire rack. Increase the oven temperature to 375°F (190°C).

In the same mixing bowl, whisk the eggs until lightly beaten. Add the granulated sugar, light brown sugar, flour, heavy cream, apple pie spice, and salt. Whisk until smooth.

Fold in the sliced apples, ensuring they are well coated. Spread the apple mixture evenly over the warm crust. Crumble the reserved dough evenly over the top.

Bake for 55 to 60 minutes, or until the topping is golden brown, the apples are tender, and the filling has thickened to a jam-like consistency.

Allow the bars to cool completely in the pan for about 2 hours. Use the parchment overhang to lift them out, then slice into 12 to 16 bars.

Servings and timing

Servings: 12 to 16 bars

Preparation time: 40 minutes
Cooking time: 1 hour 15 minutes to 1 hour 25 minutes
Cooling time: 2 hours

Total time: Approximately 3 hours 40 minutes to 3 hours 50 minutes

Variations

For thinner bars, use a 9×9-inch pan and begin checking for doneness around 45 minutes.

Swap apple pie spice with a homemade blend of cinnamon, a pinch of nutmeg, a dash of ginger, and a small pinch of cloves.

If you prefer a slightly less rich filling, substitute half-and-half or whole milk for the heavy cream.

Add 1 tablespoon of lemon juice to the apple mixture if using sweeter apple varieties to enhance brightness.

For extra texture, stir 1/3 cup chopped toasted walnuts or pecans into the reserved crumb topping before sprinkling it over the apples.

Storage/Reheating

Store the cooled bars in an airtight container at room temperature for up to 3 days.

For longer storage, freeze the bars in a single layer or between sheets of parchment paper in an airtight container for up to 3 months. Thaw at room temperature before serving.

To reheat, warm individual bars in a 300°F (150°C) oven for 8 to 10 minutes or microwave for 15 to 20 seconds until slightly warmed through.

FAQs

Can I skip browning the butter?

Can I use store-bought apple pie spice?

Yes, store-bought apple pie spice works perfectly in this recipe.

What if I slice the apples thicker?

Thicker slices may require a longer baking time and could result in a slightly firmer texture.

Can I add nuts to the crust?
