All Butter Cake Recipe: Velvety Layers With Buttery Flavor Lock

This all butter cake recipe delivers layers so tender and rich they'll make you question whether butter actually exists in liquid form. The secret lies in precise ratios—equal parts butter and sugar by weight—creating a crumb that's both velvety and sturdy enough to hold delicate fillings. I've baked this exact recipe for weddings and family gatherings, and it never fails to disappear within hours.

The magic happens in the creaming stage, where room-temperature butter and sugar are whipped together until light and airy, incorporating just the right amount of flour and eggs for structure without density. A 350°F oven ensures even baking, while a simple syrup glaze keeps the layers moist for days. This isn't your average box mix—it's a cake that tastes homemade even when you're feeding a crowd.

What sets this recipe apart is the butter-to-flour ratio, which prevents dryness while maintaining that signature melt-in-your-mouth texture. The layers stay perfectly tender when sliced, and the frosting—whether buttercream or ganache—adheres beautifully without sinking into the cake. Every bite delivers that unmistakable buttery richness that makes this a classic for a reason.

Ready in just 1 hour 15 minutes from start to finish, this cake scales effortlessly from a single layer for two to a three-tiered masterpiece. The key tools you'll need are a stand mixer, 9-inch pans, and a fine-mesh sieve for dusting powdered sugar. Let's get baking—your taste buds will thank you.

Ingredients for all butter cake

Equal parts butter and sugar create the secret to this velvety, crowd-pleasing cake.

The butter is non-negotiable here—European-style unsalted makes all the difference. Plugrá or Land O'Lakes Cultured are my go-tos, but any good-quality brand works. Room temperature is critical: press a finger into the butter, and it should leave a slight indent but not flatten completely. The sugar? Superfine dissolves faster for a smoother batter, but regular granulated works in a pinch. I always grab extra butter—half goes in the cake, half in the frosting. The eggs? Room temperature is key for even mixing, so take them out 30 minutes before baking. For the flour, King Arthur or Gold Medal are reliable, but any all-purpose will do.

No superfine sugar? Pulse regular sugar in a food processor for 30 seconds—it'll work in a pinch. Short on vanilla? Vanilla bean paste adds extra depth. The gelatin in the glaze might seem odd, but it's what gives that professional sheen and keeps the layers moist for days. Bloom it properly—sprinkle over cold water, let sit 5 minutes before warming. For the glaze, heavy cream should be warmed to 110°F so it doesn't cook the sugar. No heavy cream? Whole milk warmed with 1 tsp butter works too. The lemon juice brightens everything—fresh is best, but bottled works if you're in a hurry.

Butter stays fresh for 3 months in the fridge, wrapped tightly. The cake layers keep for 3 days wrapped in plastic, but honestly? It's best the day it's baked. For freezing, wrap each layer individually with plastic wrap, then foil. Thaws overnight at room temperature. The glaze can be made ahead—just reheat gently before using. I always bake two cakes at once: one for immediate serving, one for freezing. That way, I've always got a showstopper ready for birthdays or holidays.

Step-by-step instructions for all butter cake

Here's how to create the most decadent all butter cake with layers so tender they melt in your mouth.

In a stand mixer fitted with the paddle attachment, beat the 2 cups unsalted butter and 2 cups granulated sugar on medium speed for 5-7 minutes until the mixture is pale, thick, and nearly doubles in volume. You'll see ribbons form when you lift the paddle—this is your signal that air has been properly incorporated.

I like to scrape down the sides of the bowl every minute or so to ensure everything gets evenly creamed. The butter should be completely smooth with no graininess remaining. This step is crucial because it creates the cake's signature tender crumb. If you rush it, you'll end up with a dense cake instead of that velvety texture we're after.

With the mixer running on low speed, add the 4 whole large eggs, one at a time, allowing each to fully incorporate before adding the next. After all eggs are added, increase the speed to medium and beat for another 2 minutes until the mixture is thick and ribbony again.

Next, add the 1 tablespoon vanilla extract and mix for 30 seconds until fully combined. The vanilla enhances the buttery flavor and adds a subtle depth that makes this cake truly special. Here's the thing—don't overmix at this stage. You want to maintain that light, airy texture we've worked so hard to create.

In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 teaspoons baking powder, and 0.5 teaspoon salt. Sift the mixture directly into the wet ingredients, then gently fold using a spatula until just combined. You should still see some flour streaks—this prevents developing too much gluten, which would make the cake tough.

I like to use the "cut and fold" method here: cut through the center of the batter with the spatula, then fold the edges toward the center. Repeat until the flour is evenly distributed but the batter remains light. The goal is to maintain as much air as possible in that butter mixture we worked so hard to create.

Preheat your oven to 350°F and grease two 8-inch round cake pans with 2 tablespoons vegetable oil, then line the bottoms with parchment paper. Divide the batter evenly between the pans, smoothing the tops with a spatula. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.

I always check for doneness at the 25-minute mark because ovens vary. The cake should be golden on top and spring back when gently touched in the center. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before assembling. This cooling step is important—it prevents the layers from becoming soggy when you add the filling.

While the cakes cool, prepare the simple syrup glaze by combining 1 cup powdered sugar, 0.25 cup heavy cream, and 1 tablespoon lemon juice in a small saucepan. Warm over low heat, stirring constantly until the powdered sugar dissolves completely. Remove from heat and let cool for 5 minutes—it should be thick enough to coat the back of a spoon.

For the gelatin layer (which gives that professional "flavor lock" effect), bloom the 0.5 teaspoon unflavored gelatin in 2 tablespoons cold water for 5 minutes, then heat gently until fully dissolved. Mix this into the warm glaze and let cool completely before assembling the cake. This step might seem fussy, but it's what makes this cake stay moist for days.

Once the cakes are completely cool, level the tops if needed. Place the first layer on a cake stand or plate, then spread half of the glaze evenly over the top. Add the second layer and spread the remaining glaze over the top and sides. Chill the cake in the refrigerator for at least 4 hours, preferably overnight, to allow the gelatin to set properly.

This chilling time is non-negotiable—it lets the gelatin firm up, creating that perfect "flavor lock" that keeps the cake moist and prevents the filling from leaking. When you're ready to serve, dust with powdered sugar if desired. Each slice should be rich, buttery, and perfectly balanced between tender crumb and creamy filling.

Perfect pairings for this dish

Buttercream Frosting

This classic American buttercream is my go-to for this cake—it's rich, smooth, and pairs perfectly with the buttery layers. Whip 2 cups unsalted butter (softened), 4 cups powdered sugar, and 2 tablespoons vanilla extract until fluffy. For extra flavor, add 2 tablespoons heavy cream to create a lighter consistency. Spread between layers and over the top, then chill for 30 minutes before serving. 🍰

Fruit Fillings

Fresh berries add a bright contrast to the richness. I love a raspberry jam filling made with 1 cup raspberry jam (like Bon Appétit brand) warmed with 1 teaspoon lemon juice until smooth. Spread between layers and cover with plastic wrap to prevent sticking. For a tropical twist, use mango purée—blend 2 cups ripe mangoes with 1 tablespoon lime juice and strain. The acidity cuts through the butter beautifully.

Cream Cheese Frosting

For a tangy-sweet balance, try a cream cheese frosting. Beat 8 ounces cream cheese (softened) with 1 cup butter, 3 cups powdered sugar, and 1 teaspoon vanilla until smooth. This frosting holds its shape well and adds a sophisticated twist. Pipe it onto the cake for a decorative finish, or spread it thinly between layers for a subtle flavor. Chill for 1 hour before slicing to set properly.

Chocolate Ganache

A dark chocolate ganache elevates this cake to restaurant-quality. Melt 12 ounces dark chocolate (70% cacao) with 1 cup heavy cream, then cool slightly before pouring over the cake. Let it set at room temperature for 2 hours. For a lighter option, add ½ cup whipped cream to the ganache before pouring. Garnish with chocolate shavings or fresh raspberries for a stunning presentation. 💫

Coffee or Spiced Fillings

For an adult-friendly twist, infuse the glaze with espresso powder or cinnamon. Add 1 teaspoon instant espresso powder to the glaze for a mocha flavor, or ½ teaspoon ground cinnamon for warmth. These subtle additions complement the butter without overpowering it. A caramel filling made with 1 cup caramel sauce (like Smucker's) and 1 tablespoon butter also pairs wonderfully with the cake’s richness.
