Desserts
Alison Roman's brown butter buttermilk cake delivers the perfect harmony of nutty, caramelized richness and tender, moist crumb—every slice feels like a hug. The secret lies in browning the butter until it's golden and fragrant, then swirling it into the buttermilk batter for layers of flavor that dance between sweet and savory. I've perfected this technique over countless batches, and the result is a cake with crisp edges and a velvety center that begs for another forkful.
What makes this recipe truly special is how the buttermilk tenderizes the crumb while the brown butter adds depth that store-bought cakes can't match. The texture is light yet substantial, with just enough structure to hold its shape while melting in your mouth. Alison Roman's signature approach balances simplicity with sophistication—no fancy techniques, just high-quality ingredients working together to create something extraordinary.
By the time it emerges from the oven, you'll have a cake with golden swirls of nutty brown butter peeking through the tender crumb, promising a flavor experience that's both comforting and refined. The aroma alone will have everyone gathering around the kitchen, and the first bite delivers on that promise—rich, buttery, with just a hint of caramelized depth. This isn't just dessert; it's an experience that turns ordinary moments into something memorable.
Serve it warm with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate indulgence, or enjoy it at room temperature with a cup of coffee for a sophisticated afternoon treat. The beauty of this recipe is its versatility—it's impressive enough for company but simple enough for a weeknight dessert. Let's get baking!
Ingredients for alison roman brown butter buttermilk cake
Twelve ingredients transform into Alison Roman's legendary brown butter buttermilk cake—nutty swirls and golden crisp layers await.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cubed, for browning |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, spooned lightly |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for smoothness |
| Buttermilk 🥛 | 1 ½ cups | Room temperature, full-fat |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| Baking Powder 🍞 | 2 tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar bourbon |
| Brown Butter Swirl 🧈 | ½ cup | Nutty, golden, cooled slightly |
| Granulated Sugar (for swirl) 🍚 | ¼ cup | For butter swirl mixture |
| Heavy Whipping Cream 🥛 | ½ cup | Cold, for whipped cream |
| Powdered Sugar 🍚 | ¼ cup | For whipped cream |
| Vanilla Bean Paste 🌿 | ½ tsp | For whipped cream |
The butter is non-negotiable here—unsalted, high-fat content like Plugrá or Land O'Lakes is ideal. Browning it transforms ordinary butter into liquid gold, with that caramelized depth that makes this cake extraordinary. For the buttermilk, full-fat is critical—it's what creates that tender crumb. I always buy mine from Whole Foods or make my own by mixing milk and vinegar. The vanilla extract? Madagascar bourbon has the most complex flavor profile, but pure vanilla will work in a pinch. Sift your flour and baking powder together to avoid lumps—Diamond Crystal baking powder has more lift than others, so if you have it, use that.
No buttermilk? Substitute 1.5 cups milk with 1.5 tsp vinegar or lemon juice, let sit 5 minutes. Running short on vanilla? Vanilla bean paste adds flecks of flavor—worth the splurge if you love vanilla. The brown butter swirl mixture needs to be cool but still pourable—let it sit 10 minutes after browning. For the whipped cream, cold heavy cream and powdered sugar whipped to stiff peaks ensure that perfect dollop. If you're in a hurry, store-bought whipped cream works, but homemade elevates the whole experience. The cake itself can be made a day ahead—flavor improves with time**—just store it airtight at room temperature.
This cake keeps beautifully for 3 days at room temperature, wrapped in parchment and stored in an airtight container. For longer storage, freeze slices wrapped individually for up to 3 months**—thaw at room temperature before serving. The whipped cream should be made fresh, but you can prepare the cake ahead and whip the cream just before serving. If you're serving a crowd, double the whipped cream recipe—it disappears fast. Leftovers? Toast slices and serve with ice cream for an easy breakfast treat.

Step-by-step instructions for Alison Roman's brown butter buttermilk cake
This cake delivers layers of nutty brown butter richness with a tender crumb and golden swirls.
Brown the Butter and Prepare the Swirl
In a heavy saucepan, melt the 1.5 cups unsalted butter over medium heat. Watch closely as it foams—this is when the milk solids begin to brown. Continue cooking until the butter develops a deep golden color and emits a distinct nutty aroma, about 8-10 minutes. Immediately pour the browned butter into a heatproof bowl and stir in the 0.25 cup granulated sugar (for swirl) and 0.5 tsp vanilla bean paste. Let this mixture cool slightly while you prepare the cake batter.
While the butter cools, combine the 0.5 cup heavy whipping cream, 0.25 cup powdered sugar, and remaining 0.5 tsp vanilla bean paste in a chilled bowl. Whip with an electric mixer until soft peaks form. Fold this whipped cream into the cooled brown butter mixture to create the swirl. Set aside—this will be layered between the cake's tender crumbs.
Mix Dry and Wet Ingredients Separately
In a medium bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt. Sift the mixture lightly to aerate the flour, which helps create a tender crumb. Set aside. In a separate large bowl, combine the 1.5 cups granulated sugar with the 2 whole large eggs, mixing until fully incorporated. Add the 1 tbsp vanilla extract and mix again.
Gradually pour in the 1.5 cups buttermilk while mixing on low speed, just until combined. The batter should be thick but pourable. Scrape the bowl with a spatula to ensure all dry ingredients are fully incorporated. This careful mixing prevents overdevelopment of gluten, which would make the cake tough.
Layer and Swirl the Cake Batter
Preheat your oven to 350°F and grease two 9-inch round cake pans with butter, then line the bottoms with parchment paper. Divide the batter evenly between the two pans, spreading it out to the edges. Using a rubber spatula, create a well in the center of each layer—this is where the brown butter swirl will go.
Spoon half of the brown butter mixture into the well of each pan. Using the spatula, gently swirl the mixture through the batter in a circular motion, creating marbled patterns. This technique ensures each bite has that signature nutty flavor. Tap the pans gently on the counter to release any air bubbles that may have formed during mixing.
Bake Until Golden and Springy
Place the cake pans in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The cakes should be golden brown on top and edges, with a slight pull from the sides of the pan. Rotate the pans halfway through baking for even heat distribution.
Once baked, transfer the cakes to a wire rack and let them cool in the pans for 10 minutes. This brief resting period prevents the cakes from cracking as they cool completely. Remove from pans and cool to room temperature before assembling with the whipped cream layer.
Assemble and Serve
Place one cake layer on a serving plate and spread half of the remaining whipped cream mixture over the top. Add the second cake layer and cover the top and sides with the remaining whipped cream. Dust the top with additional powdered sugar if desired. Serve slices at room temperature for the best texture contrast between the tender cake and creamy swirl.
The cake's exterior should have a golden, slightly crisp crust, while the interior remains moist and tender. The nutty brown butter swirl adds depth to each bite, balancing the cake's subtle sweetness. Store leftovers covered at room temperature for up to 3 days or refrigerated for up to 5 days.
Pro Tips For Making Alison Roman Brown Butter Buttermilk Cake
- Brown Butter Slowly: The butter’s job here isn’t just to melt—it’s to deepen into that nutty, caramelized magic. Use medium-low heat and watch it like a hawk; if you rush it, you’ll end up with burnt bits instead of flavor. I learned this the hard way after scraping a pan full of bitter, overcooked butter off my cake batter.
- Whisk Eggs Until Ribbon Stage: Don’t just crack and stir those eggs—whisk them until they hold a slow ribbon when the whisk is lifted. This recipe relies on the eggs for structure, and under-whisked eggs mean a dense, gummy cake. (Yes, even if you’re impatient like me.)
- Measure Buttermilk Precisely: Buttermilk’s acidity is the cake’s secret weapon, but one tablespoon off throws everything off. Use a scale if you’re unsure—it should weigh about 1.03 grams per milliliter. And no, plain yogurt plus vinegar won’t cut it here; the fat content matters.
- Bake Until Internal Temp Hits 205°F: The cake’s done when the center reads 205°F—not when it looks done. I used to pull it out too soon, and the crumb ended up dry. A toothpick test is good, but the thermometer doesn’t lie. (Your future self will thank you.)
Best sauces and condiments for alison roman brown butter buttermilk cake
Brown Butter Glaze
Elevate your cake with a brown butter glaze that mirrors the nutty depth of the cake itself. Melt ½ cup unsalted butter until golden, then whisk with 1 cup powdered sugar and 1 tbsp heavy cream. Drizzle over the assembled cake while still warm—it sets beautifully and adds a glossy finish. The caramelized butter flavor ties into every bite, making it feel like a cohesive experience. 🍯
Whipped Cream Variations
Swap the standard whipped cream for vanilla bean whipped cream by infusing ½ cup heavy cream with 1 vanilla bean (split and scraped) for 1 hour before whipping. For a lighter touch, fold in 1 tbsp mascarpone cheese—it adds a luxurious creaminess without overpowering the cake. Both variations keep the cake’s signature texture while offering new flavor dimensions.
Citrus Curd Swirl
Brighten the rich cake with a lemon or orange curd swirl. Cook ½ cup curd (store-bought or homemade) with 1 tbsp cornstarch until thickened, then cool slightly. Fold it into the brown butter swirl mixture before layering—its tangy acidity cuts through the butter’s richness, creating a perfect balance. Use 1-2 tbsp per layer to avoid overwhelming the cake’s delicate flavor.
Salted Caramel Drizzle
Add a salted caramel drizzle for a sophisticated contrast. Heat ½ cup granulated sugar in a saucepan until melted, then whisk in ¼ cup heavy cream and 1 tbsp butter. Finish with a pinch of flaky sea salt and drizzle over the cake after assembly. The salt enhances the caramel’s sweetness, while the caramel complements the brown butter’s nutty notes. 💛
Spiced Honey Glaze
Infuse warmth with a spiced honey glaze. Simmer ¼ cup honey with ½ tsp cinnamon, ¼ tsp cardamom, and a pinch of black pepper until fragrant. Brush over the cake’s top layer just before serving—it adds aromatic complexity that pairs beautifully with the brown butter. The honey’s floral notes complement the cake’s richness without competing for attention.
Chocolate Ganache Layer
For chocolate lovers, replace the whipped cream with a dark chocolate ganache. Melt ½ cup dark chocolate (70% cocoa) with ½ cup heavy cream, then cool until thickened. Spread between cake layers for a decadent twist. The bitterness of the chocolate contrasts the sweetness, while the smooth texture mirrors the cake’s tenderness. Use ½ cup per layer** to avoid heaviness.

Frequently asked questions
Why does the recipe call for browning the butter?
Browning the butter transforms its flavor from simple dairy to a complex, nutty, caramelized depth that's essential to this cake. The process creates hundreds of flavor compounds that give the cake its signature richness. Without browning, you'd miss that toasty, almost toffee-like quality that makes this dessert truly special.
Can I make this cake in a single 9-inch pan instead of two?
Yes, but expect a taller, denser cake. Use a 9x2-inch round pan and reduce baking time to 35-40 minutes. The texture will be more like a pound cake rather than the classic layer cake. For best results, stick with two 9-inch pans to maintain the signature tender crumb and golden swirls.
What's the best way to store leftovers?
Wrap the cake tightly in plastic wrap, then place it in an airtight container. It stays fresh at room temperature for 3 days or in the fridge for 5 days. For longer storage, freeze individual slices wrapped in plastic for up to 3 months. Thaw at room temperature before serving for optimal texture.
Can I substitute buttermilk with something else?
Yes! Mix 1.5 cups milk with 1.5 tsp vinegar or lemon juice, then let sit for 5 minutes until it curdles. This creates the same acidic environment that activates the baking powder. For best results, use full-fat milk to maintain the cake's tender crumb.
Why does my cake have a dense texture?
Overmixing or using too much flour are common culprits. This recipe relies on careful measurement and gentle folding.
