Some cakes demand hours of effort and a long ingredient list, and some come together with pantry staples and still taste like something special. French Butter Cake is firmly in the second group. It’s built on a full cup of melted butter creamed with sugar, enriched with eggs and vanilla, folded with sour cream for a touch of tang, and baked until golden with a sugar-dusted top. The result is a tender, buttery cake that sits somewhere between a coffee cake and a pound cake, with a crumb that practically melts in your mouth.
It’s the kind of cake that needs no frosting, no decorating, and no special occasion, which makes it an easy go-to whenever a sweet craving strikes. It takes about 10 minutes of prep and 35 minutes in the oven, using ingredients most bakers already have on hand. This guide covers the complete recipe, what each ingredient contributes, tips for getting that light, tender crumb, and plenty of ideas for variations, storage, and serving.
What Is French Butter Cake?
French Butter Cake is a simple, single-layer cake baked in a square dish, with a dense yet tender crumb and a rich, buttery flavor. Think of it as a cross between a coffee cake and a pound cake, with the buttery richness of the latter and the everyday, no-fuss approachability of the former.
What makes the texture so tender is the technique: melted butter is creamed with sugar for a full minute to work air into the batter, the eggs are added one at a time to keep the mixture emulsified, and sour cream is folded in at the end for moisture and a subtle tang. A light sprinkle of sugar on top before baking gives the cake a faintly crisp, sweet crust, so there’s no need for any frosting.

Ingredients You’ll Need
The ingredient list is short, and each item plays an important role in the final texture.
Granulated Sugar
You need 1 cup of granulated sugar for the batter, plus 2 tablespoons for topping. The sugar in the batter sweetens the cake and helps create a light texture when creamed with the butter. The sugar on top adds a touch of crunch and sweetness to the finished crust.
Unsalted Butter
You need 1 cup (2 sticks) of unsalted butter, melted. Butter is the defining ingredient of this cake, providing richness and the signature buttery flavor. Melting it, rather than using it softened, is part of what gives this cake its distinct, tender crumb.
Eggs
You need 3 eggs, at room temperature. The eggs provide structure and richness. Adding them one at a time, as the recipe directs, helps keep the batter smooth and properly emulsified. Room-temperature eggs blend in more evenly than cold ones.
Vanilla Extract
You need 2½ teaspoons of vanilla extract. This generous amount gives the cake a warm, well-rounded vanilla flavor that comes through in every bite.
Cake Flour
You need 2 cups of cake flour. Cake flour has a lower protein content than all-purpose flour, which helps keep this cake’s crumb light and tender rather than dense or chewy.
Baking Powder
You need 2 teaspoons of baking powder. It provides the lift needed for the cake to rise properly in the oven.
Salt
You need 1 teaspoon of salt. It balances the sweetness and enhances the overall flavor of the cake.
Sour Cream
You need ⅔ cup of sour cream. Folded in at the end, it adds moisture and a subtle tang that keeps the cake from tasting overly sweet or heavy.
Equipment
- A 9×9-inch baking dish
- A large mixing bowl
- A hand mixer or stand mixer
- A small mixing bowl, for the dry ingredients
- A sifter or fine-mesh strainer
- A rubber spatula
- A toothpick, for testing doneness
- A wire cooling rack
How to Make French Butter Cake, Step by Step
Step 1: Preheat and Prepare the Pan
Preheat your oven to 350°F and grease a 9×9-inch baking dish thoroughly.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, add the sugar and melted butter. Mix for about 1 minute, or until the mixture is light and airy. This step introduces air into the batter, which is key to a tender final texture.
Step 3: Add the Eggs and Vanilla
Add the eggs one at a time, mixing well after each addition, then mix in the vanilla extract.
Step 4: Combine the Dry Ingredients
In a small bowl, sift together the cake flour, baking powder, and salt. Slowly add the dry mixture to the wet ingredients, mixing until just combined. Avoid overmixing, since this can make the cake tough rather than tender.
Step 5: Fold in the Sour Cream
Gently fold the sour cream into the batter until fully incorporated.
Step 6: Fill the Pan and Top with Sugar
Transfer the batter to the prepared baking dish and smooth the top. Sprinkle the remaining granulated sugar evenly over the surface.
Step 7: Bake
Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
Step 8: Cool and Serve
Allow the cake to cool before slicing and serving.

Tips for the Best French Butter Cake
Mix the Butter and Sugar for the Full Minute
This step aerates the batter, which is essential for a light, tender crumb. Don’t rush past it.
Use Room-Temperature Eggs
Cold eggs can cause the melted butter to seize slightly, leading to a less smooth batter. Let eggs sit out for about 20 to 30 minutes before using.
Don’t Overmix Once the Flour Is Added
Mix the dry ingredients in just until combined. Overmixing develops gluten and can make the finished cake dense or tough.
Fold the Sour Cream In Gently
Folding, rather than stirring vigorously, helps keep the batter light and prevents deflating the air worked in earlier.
Use Cake Flour, Not All-Purpose
Cake flour’s lower protein content is part of what gives this cake its signature tender texture. If substituting all-purpose flour, the crumb will be slightly denser.
Check for Doneness Early
Start checking at the 30-minute mark, since ovens vary. A toothpick inserted in the center should come out clean, with no wet batter clinging to it.
Let It Cool Before Slicing
Slicing too early can cause the tender crumb to fall apart. Let the cake cool enough to firm up before cutting.
Troubleshooting Common Problems
My Cake Is Dense Instead of Light
The butter and sugar may not have been mixed long enough at the start, or the batter may have been overmixed once the flour was added. Mix the butter and sugar for the full minute, and stop mixing as soon as the flour disappears.
My Cake Sank in the Middle
This can happen if the cake was underbaked or the oven door was opened too early during baking. Make sure a toothpick comes out fully clean before removing the cake, and avoid opening the oven in the first 20 minutes.
My Cake Is Dry
It was likely baked a little too long. Check for doneness starting at the 30-minute mark rather than waiting the full 35.
The Sugar Topping Sank Instead of Staying on Top
This is usually just cosmetic and won’t affect the flavor, but sprinkling the sugar right before baking, rather than letting the batter sit, helps it stay on the surface.
My Cake Stuck to the Pan
The pan wasn’t greased thoroughly enough. Grease generously, including the corners, or line the pan with parchment paper for easy removal.
My Batter Looks Curdled After Adding the Eggs
This can happen if the eggs were cold or added too quickly. Add them one at a time and make sure they’re at room temperature next time; the batter will typically smooth back out once the flour is added.
Variations to Try
Lemon Butter Cake
Add the zest of one lemon to the batter for a bright, citrusy variation.
Almond Butter Cake
Replace a teaspoon of the vanilla extract with almond extract for a nutty, bakery-style flavor.
Berry Butter Cake
Fold fresh or frozen berries into the batter before baking for bursts of fruit throughout the cake.
Cinnamon Sugar Topping
Mix a little cinnamon into the sugar used for topping for a warm, spiced crust.
Glazed Version
Drizzle a simple powdered sugar glaze over the cooled cake instead of, or in addition to, the sugar topping.
Brown Butter Version
Brown the butter before mixing it with the sugar for a deeper, nuttier flavor throughout the cake.

Make-Ahead, Storage, and Freezing
Make ahead: This cake can be baked a day in advance. The flavor and texture hold up well, and some bakers find it tastes even better the next day.
Storing at room temperature: Store the cooled cake covered at room temperature for up to 2 to 3 days.
Refrigerating: For longer storage, keep the cake in an airtight container in the refrigerator for up to a week. Let slices come to room temperature before serving for the best texture.
Freezing: This cake freezes well. Wrap the fully cooled cake, whole or in slices, tightly in plastic wrap and foil, and freeze for up to 3 months. Thaw at room temperature before serving.
Frequently Asked Questions
Can I use all-purpose flour instead of cake flour?
Yes, though the texture will be slightly denser. If you’d like to approximate cake flour, remove 2 tablespoons of flour per cup and replace it with 2 tablespoons of cornstarch.
Why melt the butter instead of using it softened?
Melted butter gives this cake its particular tender, slightly dense crumb, which is part of what sets it apart from a typical creamed-butter cake.
Can I use a different size pan?
A 9×9-inch dish is recommended for the right thickness and bake time. A different size pan will change the baking time, so watch for doneness with a toothpick rather than relying only on the clock.
Does this cake need frosting?
No. The light sugar topping provides enough sweetness and a pleasant texture on top, so frosting isn’t necessary.
Can I add mix-ins like fruit or nuts?
Yes. Berries, chopped nuts, or citrus zest can all be folded into the batter for extra flavor and texture.
Why did my cake turn out dense?
This usually comes down to either not creaming the butter and sugar long enough at the start, or overmixing once the flour was added. Both steps affect how much air is in the final batter.
How do I know when it’s done baking?
A toothpick inserted into the center should come out clean, with no wet batter clinging to it. Start checking at the 30-minute mark.
Can I double this recipe?
Yes. Use a 9×13-inch pan for a doubled batch and add a few extra minutes to the baking time, checking with a toothpick for doneness.
How should I store leftovers?
Store covered at room temperature for a few days, or in the refrigerator for up to a week. The cake also freezes well for longer storage.
Can I make this cake ahead of a party?
Yes. It can be baked a day or two in advance and stores well, which makes it a convenient option when you’re planning ahead.
Allergen Note
