Ingredients for alison roman brown butter buttermilk cake
Brown butter’s nutty aroma and buttermilk’s tang create this cake’s signature harmony—simple ingredients with restaurant-quality depth.
| 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 |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Buttermilk 🥛 | 1 ½ cups | Room temperature |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Pure Vanilla Extract 🌿 | 1 tbsp | High-quality preferred |
| Vanilla Bean Paste 🌿 | 1 tbsp | For swirls |
| Baking Powder 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Bean Seeds 🌿 | 1 tsp | Scraped from 1 bean |
| Heavy Cream 🥛 | ½ cup | Cold, for brushing |
| Flaky Sea Salt 🧂 | 1 tsp | For garnish |
The butter is non-negotiable here. European-style unsalted butter (like Plugrá or Kerrygold) browns beautifully, developing those caramelized notes that define this cake. Look for high-fat content (82% or higher) for optimal browning. If your butter is too soft, chill it for 30 minutes before cubing. For the flour, King Arthur or Gold Medal brands are ideal—they provide consistent rise and texture. The vanilla matters too: Madagascar bourbon or Tahitian vanilla extract elevates the flavor profile beyond generic imitation extracts.
No buttermilk? Mix 1.5 tablespoons lemon juice or vinegar with 1.5 cups warm milk and let sit for 5 minutes. Substituting sour cream or yogurt works too, but the tang won’t be identical. Running out of vanilla bean paste? Pure vanilla extract plus scraped seeds from one vanilla bean will mimic the texture. For the sugar, superfine dissolves more easily, but regular granulated sugar pulsed in a food processor works in a pinch. The baking powder is critical—Diamond Crystal measures differently than Rumford, so use the recipe’s amount regardless of the brand’s instructions. If you’re feeling ambitious, infuse the heavy cream with a splash of vanilla extract before brushing.
Store the cake in an airtight container at room temperature for up to 3 days—it actually improves as it sits. For longer storage, wrap tightly in plastic and refrigerate for up to 1 week. To revive, warm at 300°F for 10 minutes before serving. The brown butter flavor intensifies slightly overnight, so baking a day ahead is ideal for holiday gatherings. If you’re making this for a crowd, double the recipe—it freezes beautifully for up to 3 months when wrapped tightly in foil and plastic.

Step-by-step instructions for Alison Roman's brown butter buttermilk cake
This recipe delivers rich, nutty brown butter flavor and tender crumb with signature vanilla swirls.
Brown the Butter for Maximum Flavor
Cut the 1.5 cups Unsalted Butter into ½-inch cubes and place in a heavy saucepan over medium-low heat. Let it melt completely, then increase heat to medium and cook until the butter turns a deep golden brown color with nutty aroma—this takes about 8-10 minutes. Watch closely as it foams and bubbles, but don't walk away.
Once the butter reaches golden brown with visible browned flecks, immediately remove it from heat and let it cool for 5 minutes. This cooling step prevents the butter from continuing to cook when you add it to the dry ingredients. The nutty depth from browning is what makes this cake uniquely rich and complex—don't skip this crucial step.
Mix Wet Ingredients for Perfect Texture
In a separate mixing bowl, whisk together the 1.5 cups Buttermilk, 2 whole Large Eggs, 1 tbsp Pure Vanilla Extract, and 1 tbsp Vanilla Bean Paste until fully combined. The buttermilk should be at room temperature to ensure proper incorporation with the eggs. This mixture forms the foundation of the cake's tender crumb and moist texture.
In a large bowl, combine the 1.5 cups Granulated Sugar and 0.5 cup Light Brown Sugar (packed firmly). Slowly pour the buttermilk mixture into the sugars while mixing on low speed with an electric mixer. This gradual addition prevents sugar crystallization and creates a smooth batter. Scrape down the sides of the bowl to ensure all ingredients are fully incorporated.
Combine Dry Ingredients and Create the Swirls
In a medium bowl, sift together the 2.5 cups All-Purpose Flour, 1.5 tsp Baking Powder, and 0.5 tsp Salt. Gently fold this dry mixture into the wet ingredients using a spatula, mixing just until combined—overmixing develops gluten and creates a tough cake. The batter should be thick but pourable.
To create the signature vanilla swirls, divide the batter evenly between two 9-inch round cake pans. Using a spoon, create a well in the center of each pan's batter and add ½ tbsp Vanilla Bean Paste to each well. Gently swirl the batter with a knife to create marbled patterns. The vanilla bean paste adds both visual appeal and an extra layer of vanilla flavor that complements the brown butter.
Bake to Golden Perfection
Preheat your oven to 350°F and place the cake pans on the middle rack. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even heat distribution. The cake should be golden brown on top and have pulled away slightly from the sides of the pans.
Once the cakes are done, remove them from the oven and let them cool in the pans for 10 minutes. Then transfer to a wire rack to cool completely. This cooling period is crucial for preventing the cakes from becoming gummy. While they cool, prepare the 0.5 cup Heavy Cream by whipping it lightly with a hand mixer until soft peaks form.
Assemble and Garnish for Presentation
Once completely cool, level the tops of the cakes if needed. Place one layer on a serving plate and spread a thin layer of the whipped heavy cream on top. Add the second layer and spread more cream on top. Finally, dust the entire cake with 1 tsp Flaky Sea Salt and additional 1 tsp Vanilla Bean Seeds for a beautiful presentation and enhanced flavor contrast.
The flaky sea salt provides a delightful contrast to the sweet, nutty cake, while the vanilla bean seeds add a subtle pop of color and extra vanilla aroma. Serve immediately to enjoy the perfect balance of rich brown butter flavor and tender crumb with those signature vanilla swirls throughout.
Pro Tips For Making Alison Roman Brown Butter Buttermilk Cake
- Brown the Butter Properly: Don’t just melt it—watch for that golden foam and nutty aroma before it turns dark. If you rush, you’ll miss the depth of flavor this cake is built on (and yes, it’s worth the extra 3-5 minutes).
- Use Cold Buttermilk: Pour that buttermilk over the flour mixture after mixing wet and dry ingredients separately—no exceptions. Warm buttermilk makes the batter gummy, and this cake needs its structure. Stir just until combined, or you’ll overwork the gluten.
- Check Doneness at 325°F: The cake’s edges will pull away from the pan, but the center might still look slightly underdone. A toothpick should come out with moist crumbs, not wet batter. Overbaking dries it out—trust the internal temp over visual cues.
- Swap Brown Sugar for Turbinado: If you’re short on light brown sugar, turbinado works in a pinch, but reduce it by 20%—it’s denser. For extra crunch, sprinkle a teaspoon on top before baking. (I know, it’s not in the original, but it’s worth the tweak.)
Wine and beer pairings for this alison roman brown butter buttermilk cake
Wine Pairings
This cake’s rich brown butter and vanilla flavors call for wines with complementary depth. A dry Riesling from Germany’s Mosel region—like Dr. Loosen Blue Slate—balances the cake’s sweetness with crisp acidity and mineral notes.
The wine’s slight honeyed undertones harmonize with the brown butter’s nuttiness, while its acidity cuts through the richness. 🍷
For a red option, try a Pinot Noir with earthy, spice-driven character. I love Domaine Drouhin Oregon Pinot Noir—its red fruit and subtle oak notes mirror the cake’s vanilla swirls without overpowering. Serve it slightly chilled (50-55°F) to enhance its refreshing contrast.
Beer Pairings
A Belgian witbier like Hoegaarden or Stella Artois brings effervescence and citrus to cleanse the palate between bites. The beer’s coriander and orange peel notes complement the vanilla, while its effervescence refreshes the palate against the cake’s richness. Serve it ice-cold (38-40°F) for maximum crispness.
For a bolder beer, opt for a honey-brown ale such as Allagash White. Its caramel and spice flavors echo the brown butter’s toasty depth, while the beer’s slight sweetness enhances the cake’s vanilla. The malt-forward profile makes it a perfect match for the cake’s nutty, buttery layers.
Coffee Pairing
If you prefer coffee, a medium-roast Ethiopian Yirgacheffe with floral and citrus notes enhances the cake’s vanilla and brown butter. The coffee’s bright acidity and jasmine-like aroma create a delightful contrast, making each bite feel more vibrant.
Brew it as a pour-over or light French press to preserve its delicate flavors.
Non-Alcoholic Options
For a refreshing non-alcoholic pairing, try sparkling apple cider like Martinelli’s Sparkling Apple Cider. Its crisp acidity and apple notes mirror the cake’s vanilla while refreshing the palate. Serve it well-chilled (38-40°F) for a bright, clean contrast.
Alternatively, a vanilla chai latte with steamed milk and a dash of cinnamon complements the cake’s flavors beautifully. The warm spices enhance the vanilla swirls, while the creamy texture balances the cake’s richness. 💫

Frequently asked questions
Why does this cake use brown butter instead of regular butter?
Brown butter adds a deep, nutty aroma and caramelized flavor that regular butter can't match. The browning process creates compounds called Maillard reactions, which give the cake its signature toasty depth. This is what makes Alison Roman's version so distinct—it's not just any buttermilk cake, but one with layers of complex flavor.
Can I make this cake in a single layer instead of two?
For a single 9-inch layer, divide the batter evenly between one pan and one extra pan (or use a 10-inch pan). Bake at 350°F for 25-30 minutes until a toothpick comes out clean. The vanilla swirls will still shine through beautifully in a single layer. This works especially well for smaller gatherings or when you prefer a taller slice.
What if my brown butter doesn't brown properly?
If your butter burns before browning, reduce the heat to medium-low and watch closely—it should bubble gently for 8-10 minutes until golden with nutty flecks. For extra insurance, use European-style butter (like Plugrá) which has higher fat content. If all else fails, use 1 cup browned butter + ½ cup regular melted butter to maintain the cake's moisture and flavor.
How do I store leftovers without drying them out?
Wrap the cake tightly in plastic wrap, then place it in an airtight container with a slice of bread to absorb moisture. Store at room temperature for up to 3 days or refrigerate for 1 week. To revive, warm at 300°F for 10 minutes before serving. The cake actually improves overnight as flavors meld! For longer storage, freeze for up to 3 months in a sealed container.
Can I substitute buttermilk with something else?
Yes! Mix 1.5 tablespoons lemon juice or vinegar with 1.5 cups warm milk and let sit for 5 minutes to curdle. For a richer texture, use 1.5 cups plain yogurt or sour cream (thinned with 2 tablespoons milk if too thick). The tang is essential for the cake's moisture and balance, so avoid dairy substitutes without acidity.
