Old-fashioned Classic Buttermilk Pie Recipe made with butter, sugar, eggs, buttermilk, lemon juice, vanilla, nutmeg, and a flaky pie crust.

A humble Southern pie that somehow tastes like nostalgia wrapped in custard.

I’m going to start with a small confession about this Classic Buttermilk Pie Recipe: the first time I heard of it, I thought it sounded… weird.

Buttermilk in a pie?

I pictured something sour. Maybe heavy. Possibly the kind of dessert that polite guests take one bite of and quietly set down when no one’s looking.

Turns out, I couldn’t have been more wrong.

The first time I made this classic Southern buttermilk pie, it was late autumn—one of those chilly afternoons where the house feels quiet and you start rummaging through old cookbooks just to see what you’ll find. You know those moments? No real plan, just curiosity.

I actually found the recipe scribbled on a stained index card tucked inside my grandmother’s church cookbook. The card just said:

“Buttermilk Pie – always disappears.”

That was the entire review.

And honestly… that sounded promising.

So I made it. Butter, sugar, eggs, buttermilk. Nothing fancy. The kind of ingredient list that almost feels suspiciously simple.

While it baked, the kitchen started smelling like vanilla and toasted sugar. That warm bakery smell that makes everyone suddenly “just walk through the kitchen” for no reason.

When I sliced it later (okay, I didn’t wait as long as I should have—who does?) the filling had turned soft and custardy with this delicate golden top.

And the flavor?

Sweet, creamy, slightly tangy, with this quiet little whisper of nutmeg that sneaks up at the end.

I remember thinking… why don’t more people talk about this pie?

Have you ever stumbled across a recipe like that? Something old-fashioned that somehow feels brand new again?

Because that’s exactly what this Classic Buttermilk Pie Recipe felt like.

Why you’ll Love this Classic Buttermilk Pie Recipe?

The thing about a Classic Buttermilk Pie Recipe is that it’s not trying to impress anyone. It’s not layered. It’s not dramatic. There’s no towering frosting situation happening here.

And yet… people remember it.

The texture alone is worth talking about. The filling sets into this smooth custard that’s creamy but still sliceable. Not runny. Not stiff. Somewhere in that perfect middle ground.

And the flavor is surprisingly balanced. Sweet, yes. But the buttermilk adds just enough tang to keep things interesting.

It’s kind of like the pie version of sweet tea with lemon—familiar, comforting, but with a little personality.

Plus, the ingredients are simple. Butter, sugar, eggs, buttermilk.

That’s it.

No fancy pastry techniques. No obscure ingredients you have to hunt down at a specialty store.

Just mix. Pour. Bake.

Honestly, I’m not totally sure why this Classic Buttermilk Pie Recipe isn’t as famous as pecan pie. Maybe it’s just quieter. Less flashy.

But sometimes the quiet desserts end up being the best ones.

Ingredient Notes

If you look at the ingredient list for this Classic Buttermilk Pie Recipe, it almost reads like a pantry inventory. Which is probably why this pie became so popular in Southern kitchens generations ago.

Nothing wasted. Nothing complicated.

• Pie Crust – You can use a homemade crust if you want to go full old-school. But honestly? Store-bought crust works just fine here. I’ve used both depending on how ambitious I feel that day.
• Butter – Softened butter adds richness and helps create the silky custard filling.
• Sugar – Sugar sweetens the pie and helps form that delicate golden layer on top as it bakes.
• Eggs – Eggs give structure to the filling and help it set into that signature custard texture.
• Flour – Just a little flour stabilizes the filling so it slices neatly instead of collapsing.
• Buttermilk – The star of this Classic Buttermilk Pie Recipe. Buttermilk adds tang and depth that keeps the pie from being overly sweet.
• Lemon Juice – Just a splash brightens the whole filling. It’s subtle, but important.
• Vanilla Extract – Vanilla adds warmth and rounds out the flavor.
• Nutmeg – Freshly grated nutmeg brings a gentle spice that feels cozy and nostalgic.

How to Make Classic Buttermilk Pie Recipe?

The funny thing about this Classic Buttermilk Pie Recipe is that it looks impressive… but the process is almost ridiculously simple.

Which, honestly, is my favorite kind of baking.

Step 1: Preheat the Oven

Start by preheating your oven to 350°F.

Place your 9-inch pie crust into a pie plate and set it aside. Try not to snack on the crust scraps. (No judgment if you do.)

Step 2: Cream the Butter and Sugar

In a mixing bowl, beat the butter and sugar together until smooth and creamy.

You’re basically building the foundation of the filling here.

Step 3: Add the Eggs

Add the eggs, one at a time, beating after each addition.

The mixture will start looking creamy and slightly glossy.

Step 4: Stir in Flour and Salt

Add the flour and salt and mix until incorporated.

This small step helps the filling hold its structure once baked.

Step 5: Add the Buttermilk Mixture

Now pour in the buttermilk, lemon juice, vanilla, and nutmeg.

Mix until smooth.

At this point the batter will look fairly thin, which is completely normal for a Classic Buttermilk Pie Recipe.

Step 6: Fill the Pie Shell

Pour the filling into the prepared pie crust.

Try not to overfill… although if you’re like me, you might push that line a little.

Step 7: Bake the Pie

Bake for 45 to 55 minutes.

The top will turn lightly golden and the center will set with just the faintest jiggle.

Step 8: Cool Before Serving

Let the pie cool completely before slicing.

I know. Waiting is hard.

But if you slice too soon, the filling might not fully set. Ask me how I know.

Storage Options

If you somehow end up with leftover slices of this Classic Buttermilk Pie Recipe, they keep very well.

Just cover the pie and refrigerate it for about 3 to 4 days.

Some people prefer it chilled straight from the fridge. Others like it closer to room temperature.

Personally? I’ll eat it either way.

Sometimes standing at the fridge with a fork. Just saying.

Variations & Substitutions

One thing I enjoy about a Classic Buttermilk Pie Recipe is how flexible it can be.

• Coconut Buttermilk Pie – Stir in shredded coconut for texture and sweetness.
• Bourbon Buttermilk Pie – A splash of bourbon adds warmth and a little Southern flair.
• Maple Buttermilk Pie – Swap part of the sugar for maple syrup for deeper flavor.

Recipes evolve. That’s part of the fun.

Sometimes the best versions happen by accident.
