Chicago-Style Bakery Apple Slices (often just called “Apple Slices” or “Apple Danish Slices”) are a iconic bakery item throughout the Midwest, particularly in Chicago. If you have ever been to a corner bakery or a deli in Chicago, you have likely seen these rectangular pastries sitting in the display case.
They are distinct from a traditional apple pie or a turnover. Here is what makes them special and how to make them.
What defines a Chicago Bakery Apple Slice?
-
The Shape: They are rectangular or square, never a whole round pie. They are designed to be a hand-held, single-serving slice.
-
The Crust: It is usually a shortbread-like crust or a dense, buttery pastry crust (not a flaky puff pastry). It is sturdy enough to hold the filling without falling apart. It often has a slightly crumbly texture.
-
The Icing: A thick, opaque, white icing (confectioners’ sugar and milk/cream) is drizzled artfully over the top. It is rarely a glaze; it is usually an icing that sets up slightly opaque.
-
The Filling: A generous layer of spiced apple filling. It is not soupy; it is thick and holds its shape.
Here is a recipe to replicate that classic Chicago bakery case taste at home.
Chicago-Style Bakery Apple Slices Recipe
This recipe creates a sturdy shortbread crust bottom, a layer of homemade apple filling, and a crumb topping, all finished with that signature white icing.
Ingredients
For the Crust (Bottom Layer):
-
1 cup (2 sticks) unsalted butter, softened
-
1/2 cup granulated sugar
-
2 cups all-purpose flour
-
1/4 tsp salt
For the Apple Filling:
-
4-5 medium Granny Smith apples (or Honeycrisp), peeled, cored, and diced small (about 4 cups)
-
1/2 cup granulated sugar
-
1/4 cup brown sugar, packed
-
2 tbsp all-purpose flour
-
1 tsp cinnamon
-
1/4 tsp nutmeg
-
1 tbsp lemon juice
-
1 tsp vanilla extract
For the Crumb Topping:
-
3/4 cup all-purpose flour
-
1/2 cup granulated sugar
-
1/4 cup brown sugar, packed
-
1/2 cup (1 stick) unsalted butter, melted
-
1 tsp cinnamon
For the White Icing (The Signature Look):
-
1 cup confectioners’ sugar, sifted
-
2-3 tbsp milk or heavy cream
-
1/2 tsp vanilla extract
Instructions
1. Prepare the Crust
-
Preheat oven to 350°F (175°C) . Grease a 9×13 inch baking pan or line it with parchment paper (leaving a sling for easy removal).
-
In a medium bowl, cream together the softened butter and 1/2 cup sugar until light and fluffy.
-
Gradually add the 2 cups of flour and salt, mixing until a soft dough forms. It will be thick and crumbly but should hold together when pressed.
-
Press the dough firmly and evenly into the bottom of the prepared pan. Press it about 1/4-inch up the sides slightly to create a lip to hold the filling.
-
Bake the crust alone for 15-18 minutes, or until it is just set and the edges are very lightly golden. Do not overbake. Set aside to cool slightly while you make the filling.
2. Prepare the Apple Filling
-
In a large bowl, toss the diced apples with lemon juice and vanilla.
-
In a separate small bowl, whisk together the granulated sugar, brown sugar, 2 tbsp flour, cinnamon, and nutmeg.
-
Pour the dry mixture over the apples and stir until all the apples are evenly coated.
3. Prepare the Crumb Topping
-
In a medium bowl, whisk together the 3/4 cup flour, 1/2 cup granulated sugar, 1/4 cup brown sugar, and 1 tsp cinnamon.
-
Pour the melted butter over the flour mixture and stir with a fork until it forms clumps and crumbles. Do not overmix into a paste; you want distinct crumbs.
4. Assemble the Slices
-
Spread the apple filling evenly over the pre-baked crust.
-
Sprinkle the crumb topping evenly over the apples, covering them completely.
-
Bake at 350°F (175°C) for 35-45 minutes, until the topping is golden brown and the apple filling is bubbly around the edges.
-
Place the pan on a wire rack and allow to cool completely. This is crucial! If you cut them while warm, they will fall apart.
5. Add the Icing
-
Once the bars are completely cool, make the icing: Whisk together the sifted confectioners’ sugar, 2 tbsp of milk, and vanilla. Add the last tbsp of milk if needed to achieve a thick but drizzling consistency (it should be thicker than a glaze but thinner than toothpaste).
-
Use a fork or a piping bag with a small tip cut off to drizzle the icing back and forth across the top of the bars in a striped pattern.
-
Let the icing set for about 15-20 minutes before slicing into rectangles.
Tips for Authenticity
-
The Apple: Granny Smith apples are the classic choice for bakeries because they hold their shape and provide a tartness that balances the sweet crust and icing.
-
The Icing: This is what sets it apart from a regular apple crumble bar. The thick white icing is the “Chicago” signature.
-
Serving: These are often enjoyed at room temperature with a cup of coffee (or a milk chaser, if you are a kid in Chicago).
