French Butter Cake is a rich, tender cake with a buttery crumb, delicate golden crust, and a simple vanilla flavor that lets the quality of the ingredients shine. It is made with creamed butter and sugar, eggs, flour, and a small amount of dairy for a moist texture without requiring frosting or elaborate decoration.

This cake is straightforward to prepare in a 9-inch round cake pan and is especially good served slightly warm or at room temperature. A careful creaming step and gentle mixing help create an even crumb, while baking at moderate heat allows the center to cook without over-browning the edges.

What Makes This Recipe Work

Butter provides richness and a tender crumb. Creaming the butter with sugar also incorporates air that helps give the cake a lighter texture.
Room-temperature eggs blend more smoothly. They emulsify more easily with the butter mixture, reducing the chance of a curdled batter.
A modest amount of leavening keeps the cake tender. The cake rises without becoming overly airy or sponge-like.
Vanilla complements the buttery flavor. It adds depth without competing with the main flavor of the cake.
Cooling before slicing helps the crumb set. The cake becomes easier to cut cleanly while retaining its moisture.

Ingredient Notes

■ Unsalted butter: Main source of richness; use salted butter without added salt.
■ All-purpose flour: Provides structure; can replace with cake flour for a softer crumb.
■ Whole milk: Adds moisture; half-and-half can be used for a richer cake.
■ Granulated sugar: Sweetens and aerates the butter; avoid large reductions.
■ Eggs: Provide structure and emulsification; no reliable substitutes for texture.

Step-by-Step Method

Prepare the pan. Heat the oven to 350°F (175°C). Grease a 9-inch (23-cm) round cake pan with 1 tablespoon (14 g) softened butter, dust with 1 tablespoon (8 g) flour, and tap out the excess. Line the bottom with parchment paper for easier release.
Combine the dry ingredients. Whisk the flour, baking powder, and salt together in a medium bowl. Set aside.
Cream the butter and sugar. In a large bowl, beat the 1 cup (227 g) softened butter and granulated sugar with an electric mixer on medium speed for about 3 to 4 minutes. The mixture should look pale, creamy, and noticeably lighter in texture.
Add the eggs and vanilla. Add the eggs one at a time, mixing on medium-low speed after each addition until incorporated. Scrape down the bowl as needed. Mix in the vanilla. If the mixture looks slightly curdled, continue with the recipe rather than adding extra flour.
Add the flour and milk. Add about one-third of the flour mixture to the butter mixture and mix on low speed just until nearly incorporated. Add half of the milk, followed by another third of the flour mixture. Add the remaining milk and finish with the remaining flour. Mix only until no dry flour remains.
Fill the pan. Transfer the batter to the prepared cake pan and smooth the top with a rubber spatula. The batter should be thick but spreadable and should sit evenly in the pan.
Bake. Bake at 350°F (175°C) for 38 to 42 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean or with a few moist crumbs attached. The center should spring back lightly when gently pressed.
Cool the cake. Let the cake cool in the pan on a wire rack for 10 minutes. Run a thin knife around the edge if needed, then carefully remove the cake from the pan and place it on the rack. Cool for another 20 minutes before slicing.
Serve. Serve the cake slightly warm or at room temperature. Dust with optional powdered sugar and serve with fresh berries if desired.

Kitchen-Tested Tip

Use properly softened butter. It should yield easily when pressed but should not look oily or melted.
Measure flour accurately. Too much flour can make a butter cake noticeably dense and dry.
Do not overmix after adding flour. Mix only until the batter is uniform to protect the tender crumb.

Make-Ahead and Storage Notes

Store the cooled cake in an airtight container at room temperature for up to 3 days.
For longer storage, wrap the completely cooled cake tightly in plastic wrap and freeze for up to 2 months.
The cake can be baked 1 day ahead and kept covered at room temperature.

FAQ

Can I use salted butter?

Yes. Replace the unsalted butter with the same amount of salted butter, but omit the 1/4 teaspoon (1 g) added salt.

Why is my French Butter Cake dense?

Overmixing after adding the flour, using too much flour, or failing to cream the butter and sugar sufficiently can make the cake dense. Cream the butter and sugar until pale and fluffy, then mix the flour in gently.

Can I make this cake ahead of time?

Yes. Bake it up to 1 day ahead and keep it covered at room temperature.

Can I use a different pan?

A 9-inch (23-cm) round pan gives the intended thickness. A different-size pan will change the baking time and cake height, so monitor the cake closely and rely on doneness cues rather than the original timing alone.

How do I know when the cake is done?

The top should be golden brown, the center should spring back lightly when touched, and a toothpick inserted into the center should come out clean or with a few moist crumbs rather than wet batter.
