Step‑by‑Step Instructions for Apple Buttermilk Custard Pie With Crumble Topping Step 1: Prepare the Pie Crust Begin by preheating your oven to 325°F (160°C). Grease a pie plate with cooking spray or melted butter, then carefully line it with your pie crust, ensuring it fits snugly. For easier handling, place the crust in the freezer while you prepare the filling and crumble topping, which will prevent it from shrinking during baking. Step 2: Make the Crumble Topping In a mixing bowl, combine brown sugar, all-purpose flour, old-fashioned oats, and ½ teaspoon of ground cinnamon. Use a fork or your fingers to mix in the diced butter until the mixture resembles coarse crumbs. This crumble topping adds a delightful crunch to your Apple Buttermilk Custard Pie, so set it aside once fully combined. Step 3: Prepare the Apples While the crumble topping rests, peel, core, and slice the apples into thin wedges, aiming for about ¼ inch thick. To keep the apples vibrant, soak them in a bowl of cold water mixed with a squeeze of lemon juice for 10 minutes. This simple step prevents browning, ensuring your pie looks as beautiful as it is delicious. Step 4: Cook the Apples In a large skillet, melt 3 tablespoons of unsalted butter over medium heat. Once melted, add the sliced apples, ¼ cup of granulated sugar, and ¼ teaspoon of cinnamon. Sauté the mixture for about 10 minutes, stirring occasionally, until the apples are tender and coated in a lovely syrup. Allow the mixture to cool slightly before using. Step 5: Prepare the Custard Filling In a mixing bowl, whisk together the remaining ¾ cup of granulated sugar, cornstarch, and ¼ teaspoon of salt. Crack in the 3 large eggs and add 1¾ cups of full-fat buttermilk and 1 teaspoon of vanilla extract. Whisk until the mixture becomes smooth and well combined, creating a creamy foundation for your Apple Buttermilk Custard Pie. Step 6: Assemble the Pie Now it’s time to bring everything together! First, layer the cooked apples evenly in the prepared pie crust, forming a beautiful base. Pour the custard filling over the apples, ensuring it covers them completely. Finally, sprinkle the crumble topping generously on top of the custard layer, creating an irresistible crispy layer that finishes off your pie perfectly. Step 7: Bake the Pie Cover the pie loosely with aluminum foil and place it in the preheated oven. Bake for 30 minutes, then remove the foil to allow the topping to brown. Bake for an additional 25-30 minutes, or until the custard sets and is firm to the touch, giving it a golden-brown appearance. Your Apple Buttermilk Custard Pie is nearly ready! Step 8: Cool and Serve Once baked, remove the pie from the oven and let it cool on a wire rack for at least 30 minutes. This cooling time allows the custard to firm up properly. Serve your warm Apple Buttermilk Custard Pie plain or with a scoop of vanilla ice cream to take it to the next level of deliciousness. Make Ahead Options These delicious Apple Buttermilk Custard Pies are ideal for meal prep, saving you valuable time during busy holiday seasons! You can prepare the pie crust and crumble topping up to 24 hours in advance, storing them separately in the refrigerator to maintain their fresh textures. Additionally, you can slice and cook the apples 3 days ahead, just be sure to refrigerate them to preserve their flavor and prevent browning. When you’re ready to serve, simply assemble the pie by layering the apples, pouring over the custard filling, and topping with the crumble before baking according to the instructions. This way, you’ll enjoy a homemade dessert that’s just as delicious with minimal effort!

Apple Buttermilk Custard Pie With Crumble Topping Recipe FAQs What type of apples should I use for the pie? Absolutely! For the best flavor balance, opt for tart apples like Granny Smith or Honeycrisp. These varieties provide a natural sweetness that complements the custard perfectly. Avoid using overripe apples, as they can become mushy during baking, affecting the overall texture of your pie. How should I store my leftover pie? The more the merrier! To keep your Apple Buttermilk Custard Pie fresh, cover it and refrigerate for up to 4 days. This helps maintain its creamy texture and delicious flavor. Make sure it’s in an airtight container or wrapped tightly with plastic wrap to prevent it from drying out. Can I freeze the pie? Yes, you can! Unbaked Apple Buttermilk Custard Pies can be frozen for up to 3 months. Wrap your pie tightly in plastic wrap or aluminum foil. When you’re ready to bake, simply remove it from the freezer and bake it directly from frozen, adding about 10-15 extra minutes to the baking time to ensure it’s cooked through. What should I do if my filling turns out runny? Very often, a runny filling results from not cooking the apples enough or using too much liquid. To prevent this, ensure that the apples are fully tender but not mushy before incorporating them into the custard. If you find your filling is still too wet after mixing, try adding an extra tablespoon of cornstarch to thicken it. Are there any dietary considerations I should keep in mind? I recommend it! If you’re making this pie for someone with allergies, be sure to check that the ingredients fit their dietary needs. If you have guests who are lactose intolerant, you can try substituting the full-fat buttermilk with a lactose-free version or a homemade buttermilk replacement using almond or soy milk mixed with a tablespoon of vinegar. Just keep in mind that this may slightly alter the taste and texture.
