Classic Southern Buttermilk Custard Pie Ingredients
Here’s what you’ll need to make the custard pie filling and crust, plus how each ingredient earns its place in the recipe.
- 1 unbaked 9-inch pie crust – Forms the flaky, buttery base that holds the rich custard; use homemade or a quality store-bought crust.
- 1 ½ cups granulated sugar – Sweetens the pie and helps create that signature shiny, lightly crackled top as it bakes.
- ½ cup (1 stick) unsalted butter, melted and slightly cooled – Adds richness and a velvety texture to the custard filling.
- 3 large eggs – Provide structure, helping the custard set so it slices cleanly while staying soft and creamy.
- 1 cup buttermilk – The star ingredient; gives the pie its subtle tang and classic Southern custard flavor.
- 3 tablespoons all-purpose flour – Slightly thickens the filling so it isn’t runny and helps it bake into a smooth, stable custard.
- 1 teaspoon vanilla extract – Rounds out the sweetness and gives the pie a warm, comforting flavor.
- ¼ teaspoon salt – Balances the sugar and brings out all the flavors in the custard.
- ¼ teaspoon ground nutmeg (optional) – A light sprinkle on top adds a gentle spice note and a pretty, old-fashioned look.
Step-by-Step Classic Southern Buttermilk Custard Pie
STEP 1: Preheat your oven to 350°F (175°C). Place the oven rack in the center position so the pie bakes evenly and the crust browns without burning.
STEP 2: Fit the unbaked pie crust into a 9-inch pie dish, pressing it gently into the bottom and sides. Crimp or flute the edges if you’d like a decorative border, then set the crust aside while you mix the filling.
STEP 3: In a large mixing bowl, whisk together the granulated sugar, melted (slightly cooled) butter, and flour until there are no lumps. You’re looking for a smooth, thick paste-like mixture as your base.
STEP 4: Add the eggs one at a time, whisking well after each addition. This step builds the custard structure and helps prevent streaks of egg from showing in the baked pie.
STEP 5: Pour in the buttermilk, vanilla extract, and salt. Whisk until the mixture is completely smooth and well combined. It will be thin and pourable—this is exactly what you want for a silky custard.
STEP 6: Place the pie dish on a baking sheet (this makes it easier to transfer). Pour the filling into the prepared crust. If you’re using nutmeg, lightly dust the top with a pinch or two, being careful not to overdo it.
STEP 7: Transfer the pie (on the baking sheet) to the center rack and bake for 50–60 minutes. The edges will be set and puffed, and the center should look mostly set with a slight wobble. A knife inserted about 2 inches from the center should come out clean.
STEP 8: Remove the pie from the oven and place it on a wire rack. Let it cool completely before slicing so the custard can finish setting. Serve at room temperature or chilled, with whipped cream if you like.
What to Serve with Classic Southern Buttermilk Custard Pie
Buttermilk pie pairs beautifully with fresh berries. A handful of sliced strawberries, raspberries, or blueberries on the plate cuts through the richness and adds a fresh, juicy contrast.
For a more indulgent dessert plate, add a scoop of vanilla ice cream or a generous swirl of lightly sweetened whipped cream. The cold cream against the smooth custard is especially nice if you serve the pie at room temperature.
To keep things simple but still special, offer hot coffee or tea alongside each slice. The warm drink balances the sweetness and makes this pie feel right at home after a big meal or holiday feast.
Pro Tips for Classic Southern Buttermilk Custard Pie
- Protect the crust edges: If the crust is browning too quickly, loosely cover the outer edge with strips of foil or a pie shield during the last 15–20 minutes of baking.
- Check for doneness gently: Use the “2 inches from the center” knife test and look for a soft wobble, not a liquid center; it will firm up as it cools.
- Chill for cleaner slices: For super neat wedges, refrigerate the cooled pie for several hours, then slice with a sharp knife wiped clean between cuts.
Can I use a store-bought pie crust?
Yes. A good-quality refrigerated or frozen pie crust works perfectly and keeps this dessert very beginner-friendly. Just thaw according to package directions before filling and baking.
Why is my buttermilk pie runny in the center?
Usually it just needs more baking time. Bake until only the very center has a slight jiggle and the knife test near the center comes out mostly clean, then cool completely.
Can I make this buttermilk pie ahead of time?
Absolutely. Bake the pie a day in advance, cool it fully, then cover and refrigerate. Bring to room temperature or lightly chill before serving for the best texture.
Do I need to refrigerate leftover buttermilk pie?
Yes. Because it’s a custard pie made with eggs and dairy, leftovers should be stored covered in the refrigerator and not left at room temperature for long periods.
How to Store & Reheat Buttermilk Custard Pie
Once the pie has cooled completely, cover it well with plastic wrap or foil and store it in the refrigerator. It will keep its flavor and texture for about 3–4 days, making it ideal for baking ahead of holidays or gatherings.
For longer storage, you can freeze buttermilk pie. Chill the baked pie thoroughly, then wrap the whole pie or individual slices tightly in plastic wrap and a layer of foil. Freeze for up to 2 months. Thaw in the refrigerator overnight before serving.
You can enjoy this pie straight from the fridge, but if you prefer it slightly warm, reheat individual slices. Place a piece on a microwave-safe plate and warm it in 10–15 second bursts, just until barely warm to the touch—overheating can cause the custard to weep or turn rubbery.

Preheat the Oven
