Ingredients

• 1 stick unsalted butter (softened)
• ⅓ cup light brown sugar
• ½ teaspoon vanilla extract
• ⅛ teaspoon salt
• 1 cup + 2 tablespoons all purpose flour
• ⅔ cup condensed milk
• 2 eggs
• ⅓ cup spiced apple cider
• 1 ½ teaspoons flour
• ½ teaspoon baking powder
• ⅛ teaspoon salt
• 2 tablespoons butter
• 3 cups apple, peeled, cored, and shredded on a cheese grater
• 3 tablespoons brown sugar
• 1 tablespoon maple syrup
• ¼ teaspoon cinnamon

How to make Apple Custard Bars

Step 1: First things first, get your oven preheating to 350°F. Grab an 8×8 inch baking pan and line it with parchment paper, leaving some overhang on the sides to act as handles. This will make it super easy to lift the bars out later. Set the prepared pan aside.

Step 2: Now, let’s make the shortcrust. In a stand mixer bowl or a large bowl using a pastry cutter, combine the softened butter, light brown sugar, vanilla, salt, and flour. Mix until the ingredients come together and form large, crumbly clumps. The dough should stick together when you press it between your fingers.

Step 3: Transfer the dough to your prepared pan. Press it down firmly and evenly across the bottom. To prevent the crust from puffing up while it bakes, take a fork and poke holes all over the surface.

Step 4: Slide the pan into the oven and bake for about 20 minutes. You’re looking for the edges to just start turning a lovely golden brown. Once baked, carefully remove it from the oven and set it aside.

Step 5: While the crust is baking, you can prepare the custard filling. In a large bowl, whisk together the condensed milk, eggs, and spiced apple cider until everything is smooth and fully combined. Then, add the 1 ½ teaspoons of flour, baking powder, and salt, and whisk again until just incorporated.

Step 6: Pour this creamy custard mixture over the warm, par-baked crust. Return the pan to the oven and bake for another 20-25 minutes. The custard is done when the top is lightly browned and the center has just a slight jiggle. Don’t overbake it!

Step 7: Remove the bars from the oven and let them cool completely on a wire rack. Once at room temperature, transfer the pan to the refrigerator and chill for at least 2-3 hours, or until the custard is firm and cold.

Step 8: While the bars are chilling, make the delicious apple topping. In a small skillet, melt 2 tablespoons of butter over medium-high heat. Add the shredded apple, brown sugar, maple syrup, and cinnamon. Cook, stirring occasionally, until the apples soften and the liquid thickens into a beautiful syrup. Let this mixture cool completely.

Step 9: When you’re ready to serve, lift the chilled bars out of the pan using the parchment paper handles. Cut them into 9 even squares. Top each bar with a generous spoonful of the cooled apple mixture. Enjoy!

How to serve Apple Custard Bars

These bars are divine served chilled, straight from the refrigerator. The cold, creamy custard is a wonderful contrast to the buttery crust and sweet apple topping. For an extra touch of indulgence, you can add a small dollop of fresh whipped cream or a light dusting of powdered sugar just before serving. They are a perfect companion to a hot cup of coffee or tea on a crisp afternoon.

How to store Apple Custard Bars

Due to the egg-based custard, these bars must be stored in the refrigerator. Place any leftovers in an airtight container. They will stay fresh and delicious for up to 4 days. I find the texture and flavor are even better on the second day once everything has had time to meld together!

Tips to make Apple Custard Bars

Don’t Overbake the Custard: The key to a silky custard is to pull it from the oven when the center is still slightly jiggly. It will continue to set as it cools. Overbaking can lead to a rubbery texture.

Cool Completely: Patience is a virtue with this recipe! Ensure both the bars and the apple topping are completely cooled (and the bars are chilled) before you assemble them. This prevents the topping from melting into the custard and keeps the layers distinct.

Apple Selection: The recipe calls for Gala apples, which is a great choice. Other firm-sweet apples like Honeycrisp, Fuji, or Braeburn also work beautifully. They hold their shape and provide a nice sweetness.

Parchment Sling is Key: While the recipe notes you can get by without it, using a parchment paper sling makes life so much easier. It ensures clean removal and perfect cuts every time. If you enjoy apple desserts, you’ll also love this easy Cranberry Apple Crisp.

FAQs About Apple Custard Bars

Can I make these bars ahead of time?

Absolutely! In fact, they need to be made ahead of time to allow for the proper chilling. You can bake the bars one day and serve them the next. Just keep them covered in the fridge and add the apple topping right before serving for the best results.

Can I use a different size pan?

This recipe is optimized for an 8×8 inch pan. Using a different size will alter the thickness of the crust and custard, which will change the baking time. A 9×9 inch pan will result in thinner bars that need less time, while a smaller pan will create thicker bars that need more time.

What if I don’t have spiced apple cider?

No problem! You can use regular apple cider. To get that “spiced” flavor, simply add an extra ⅛ teaspoon of cinnamon and a pinch of nutmeg to the custard filling when you add the other dry ingredients.
