Desserts
Alison Roman's brown butter buttermilk cake delivers a perfect marriage of nutty richness and tender crumb—exactly what makes this dessert stand out. The brown butter adds a deep, caramelized depth that transforms ordinary cake into something extraordinary, while the buttermilk keeps the texture impossibly moist and fine-grained. I've baked this recipe countless times, and every slice proves why it's become a modern classic.
The secret lies in the technique: browning the butter until it's fragrant and nutty (but not burnt), then cooling it before mixing. This step creates the signature flavor that sets this cake apart from traditional recipes. The buttermilk, when combined with baking soda, produces a cake that's light yet sturdy—perfect for slicing without crumbling. Even better, it stays moist for days, making it ideal for meal prep or special occasions.
What you'll end up with is a cake that's golden-brown on the outside with a tender, velvety crumb inside. The brown butter flavor shines through in every bite, balanced by the subtle tang of buttermilk. It's the kind of dessert that feels both comforting and impressive—easy to make but impossible to resist. Serve it warm with whipped cream or a scoop of vanilla ice cream for the full experience.
This recipe scales beautifully, whether you're baking for a crowd or treating yourself to a single slice. The frosting options are endless, but I recommend keeping it simple with a dusting of powdered sugar or a light glaze to let the cake's natural flavors shine. Let's get baking!
Ingredients for alison roman brown butter buttermilk cake
Brown butter and buttermilk transform this cake into a nutty, moist masterpiece—just eight ingredients, no shortcuts.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 ½ cups | Browned until nutty aroma |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, spooned lightly |
| Granulated Sugar 🍚 | 2 cups | Lightly packed |
| Buttermilk 🥛 | 1 ½ cups | Room temperature |
| Large Eggs 🥚 | 3 whole | Room temperature |
| Baking Soda 🧂 | 1 tbsp | Freshly opened |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 2 tsp | Pure vanilla |
| Powdered Sugar 🍚 | 1 cup | For dusting |
The butter is non-negotiable—European-style unsalted (like Plugrá or Land O'Lakes) browns best. Look for cold-pressed if you can; it has more flavor. I grab mine from Whole Foods or Costco when I need a big batch. Brown it in a light-colored pan so you can see when it turns golden—not black. Let it cool completely before mixing, or the cake will turn out greasy. For the buttermilk, if you don't have any, mix 1.5 tbsp lemon juice or vinegar with 1.5 cups milk and let it sit for 5 minutes.
No vanilla extract? Vanilla bean paste works even better—just use 1.5 tsp. The flour should be sifted (no lumps!) and the sugar should be packed lightly in the cup. For a gluten-free version, swap the all-purpose flour for a 1:1 blend like Bob's Red Mill. The baking soda is crucial—don't substitute baking powder—it reacts with the buttermilk for that signature lift. If you're feeling fancy, add a pinch of cinnamon or cardamom to the batter for extra warmth.
This cake keeps 5 days at room temperature wrapped in foil, but honestly, it's best the day it's made. For long-term storage, freeze slices wrapped in plastic for up to 3 months. Reheat slices in a 200°F oven for 5-10 minutes to bring back that warm, gooey texture. I always make a double batch—half goes in the freezer for lazy days. The powdered sugar? Only dust if you're serving it immediately; otherwise, save it for topping slices later.

Step-by-step instructions for Alison Roman's brown butter buttermilk cake
This cake delivers rich, nutty depth with a tender crumb—trust the process, and you'll nail it.
Brown the Butter for Maximum Flavor
Melt the 1.5 cups unsalted butter in a light-colored saucepan over medium heat. Watch closely as it foams and bubbles—this is normal. Keep cooking until the butter turns a deep golden brown and releases a nutty aroma, about 5-7 minutes. You'll see small browned bits settle at the bottom.
Immediately pour the browned butter into a heatproof bowl and let it cool for 10 minutes. This step is non-negotiable—the nutty, caramelized flavor transforms this into something special. If you skip browning, you'll miss the depth Alison Roman's recipe promises.
Whisk Dry Ingredients for Perfect Texture
In a large mixing bowl, whisk together the 2.5 cups all-purpose flour, 2 cups granulated sugar, 1 tbsp baking soda, and 0.5 tsp salt. Sift the flour lightly as you add it to prevent lumps. I like to use a whisk for this step—it aerates the mixture and ensures even distribution of the baking soda.
This dry mix should look fine and fluffy, with no visible clumps. Set it aside while you prepare the wet ingredients. The baking soda will react with the buttermilk later, creating lift and that signature tender crumb.
Combine Wet Ingredients for a Smooth Batter
To the cooled browned butter, add the 1.5 cups room-temperature buttermilk, 3 whole large eggs, and 2 tsp vanilla extract. Whisk vigorously for 2-3 minutes until the mixture is completely smooth and slightly thickened. The buttermilk should be fully incorporated with no streaks remaining.
This is where the magic happens—the buttermilk's tang balances the richness of the brown butter. If the mixture looks curdled, don't worry—it'll come together when you add the dry ingredients. The eggs should be at room temperature for best results.
Fold and Bake for a Perfect Rise
Gradually add the dry ingredients to the wet mixture, folding gently with a spatula until just combined. Overmixing develops gluten, which can make the cake dense. Stop folding when there are just a few flour streaks remaining. Pour the batter into two 9-inch round cake pans lined with parchment paper.
Bake at 350°F for 25-30 minutes, until a toothpick inserted in the center comes out clean. The cakes should spring back slightly when pressed. I recommend checking at the 25-minute mark—ovens vary, and you want that perfect golden dome.
Dust and Serve for Maximum Wow Factor
Let the cakes cool in their pans for 10 minutes, then transfer to a wire rack to cool completely. Once fully cooled, dust the tops generously with 1 cup powdered sugar using a fine-mesh sieve. This step adds that professional finish and balances the rich flavors.
The result should be a moist, tender cake with a subtle nutty depth from the brown butter and a light, airy crumb. Slice and serve with a dollop of whipped cream or fresh berries for the ultimate treat. This cake keeps well for 3 days at room temperature or 1 week refrigerated.
Pro Tips For Making Alison Roman Brown Butter Buttermilk Cake
- Brown Butter First: I learned this the hard way—don’t rush the browning. Let that butter foam, bubble, and turn a deep golden brown (almost nutty) before pulling it off the heat. If it’s pale or just melted, the cake will taste underdeveloped and lack that rich, caramelized depth Alison’s version is famous for. ---
- Whisk the Buttermilk: Give that buttermilk a good stir before measuring it out. The solids settle, and if you scoop straight from the jug, you’ll end up with a thinner batter that won’t rise as well. A quick whisk ensures consistency—no one wants a dense cake because of lazy prep. ---
- Don’t Overmix the Batter: Once you fold in the dry ingredients, stop mixing the second everything’s just combined. Overworking the batter introduces too much air, which can cause the cake to sink in the middle or develop a tough crumb. Think “gentle” here—like folding in a delicate meringue, not kneading dough. ---
- Test for Doneness Early: The cake’s done when the center springs back slowly when pressed (not instantly), and the internal temp hits 205–210°F. If you pull it out too soon, the middle will stay gummy—trust the thermometer, not just the look. A toothpick with a few moist crumbs is fine; a wet one means more time.
Essential equipment for perfect results
Must-Have Mixing Tools
Start with a stand mixer or hand mixer—I swear by my KitchenAid Artisan—to whip the butter and buttermilk into a silky emulsion. For folding dry ingredients, a flexible silicone spatula (like OXO Good Grips) prevents overmixing better than a metal one. A light-colored saucepan is essential for browning the butter so you can see when it reaches that perfect golden hue. 🧈
Precision Baking Gear
Two 9-inch round cake pans with removable bottoms (I use Wilton Perfect Results) ensure even baking and easy release. Line them with parchment paper for foolproof removal. A digital oven thermometer (like Thermoworks) guarantees your oven is at the correct 350°F—I’ve ruined cakes from miscalibrated ovens before! For testing doneness, a long toothpick is a must. 🌡️
Cooling and Finishing
A wire cooling rack prevents soggy bottoms while the cakes cool. For dusting powdered sugar, a fine-mesh sieve (like Norpro) ensures an even, professional finish. If you’re feeling fancy, a pastry brush can help apply simple glazes or melted butter for extra richness. I keep a small offset spatula handy for spreading frosting if I decide to add one later. ✨
Budget-Friendly Swaps
No stand mixer? A whisk and strong arm work just fine—just take your time. For browning butter, a small stainless steel pot works as well as a saucepan. Skip the fancy pans and use disposable aluminum pans (they crisp beautifully). A spoon or butter knife can test doneness if you don’t have a toothpick. The key is patience, not perfection. 💪
Pro Tips for Long-Term Use
Invest in a food scale (like OXO Good Grips) for precise measurements—especially for butter and flour. A lidded airtight container keeps baked slices fresh for days. For freezing, quart-sized freezer bags with labels save space and prevent freezer burn. I also keep a small bowl of powdered sugar on hand for quick dusting—no need for a sieve every time. 🧊

Frequently asked questions
Why does this cake use brown butter instead of regular butter?
The brown butter adds a deep, nutty caramel flavor that transforms this cake from ordinary to extraordinary. When butter browns, it develops complex compounds that create that signature toasty depth—something you won't get with regular melted butter. The cooling step before mixing preserves these flavors while preventing a greasy texture.
Can I substitute buttermilk if I don't have any?
Yes! Mix 1.5 tablespoons lemon juice or white vinegar with 1.5 cups milk and let it sit for 5 minutes to curdle—this creates a perfect buttermilk substitute. The acidity is crucial as it reacts with the baking soda to create lift and that signature tender crumb. Never skip this step if you want the same results.
How do I know when the brown butter is done?
Look for a deep golden color with small browned bits at the bottom and a nutty aroma filling your kitchen. The butter should smell like toasted nuts, not burnt. It typically takes 5-7 minutes over medium heat. Use a light-colored pan so you can see the color change clearly—dark pans hide the browning process.
Should I frost this cake, and if so, what works best?
Alison Roman's version is often served plain with a dusting of powdered sugar to let the flavors shine, but you can frost it if you prefer. A light vanilla bean glaze (powdered sugar + milk + vanilla) or whipped cream frosting works beautifully. For extra richness, try a thin layer of brown butter cream cheese frosting—just make sure not to overpower the cake's natural nutty depth.
What if my cake comes out dense instead of tender?
Overmixing is the most common cause—stop folding when just a few flour streaks remain. Also ensure your butter is fully cooled before mixing and your buttermilk is room temperature. If using a different flour brand, check its protein content—higher protein flours can make cakes denser. For next time, try sifting the flour more thoroughly and using a gentle hand when combining ingredients.
