Ingredients for alison roman brown butter buttermilk cake
Eight simple ingredients transform into a showstopping cake with caramelized butter notes and tender crumb.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Browned to nutty golden color |
| Buttermilk 🥛 | 1 ½ cups | Room temperature preferred |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Light Brown Sugar 🍚 | ½ cup | Packed firmly |
| Baking Powder 🍃 | 2 tsp | Diamond Crystal preferred |
| Baking Soda 🧂 | ½ tsp | Pure baking soda |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Pure Vanilla Extract 🍯 | 1 tbsp | High-quality preferred |
| Vanilla Bean Paste 🌿 | 1 tsp | For extra depth |
| Vegetable Oil 🫒 | ½ cup | Light, neutral flavor |
The butter is the star—European-style unsalted like Plugrá or Kerrygold gives the richest flavor. Brown it until it smells nutty and golden, then let it cool completely before mixing. Room temperature butter blends better, so take it out 30 minutes ahead. For the buttermilk, if you don't have any, mix 1.5 tablespoons lemon juice or vinegar with 1.5 cups milk and let sit 5 minutes. The flour should be sifted—King Arthur or Gold Medal work perfectly, but measure carefully after sifting to avoid overpacking.
No vanilla bean paste? Double the pure vanilla extract instead. For a lighter cake, replace 0.25 cup of the all-purpose flour with cornstarch. The sugars can be swapped—coconut sugar works 1:1 but has a slightly different caramelization. If you're at high altitude, reduce baking powder to 1.75 teaspoons and add 1 tablespoon cornstarch to the flour. The vegetable oil keeps the crumb tender—avocado oil works too, but stick to neutral flavors like canola or vegetable.
Brown butter keeps for 1 week in the fridge or 3 months frozen in small portions. Store the cake in an airtight container at room temperature for up to 3 days, or refrigerate for 5 days. For longer storage, freeze the baked cake wrapped tightly in plastic for 3 months. The flavor actually improves after a day or two—Alison Roman's trick—so make it ahead if you can. Slice with a serrated knife for clean cuts, and serve at room temperature for the best texture.

Step-by-step instructions for Alison Roman's brown butter buttermilk cake
This cake delivers deep caramelized flavor and a perfectly golden crust every time.
🔥 Step 1: Brown the Butter for Rich Caramel Notes
Melt the 1 cup unsalted butter in a light-colored saucepan over medium heat. Watch closely as it foams and bubbles—this takes about 5-7 minutes. The butter will transform from pale yellow to a golden brown color with nutty aroma. Here's the thing: don't walk away. If it browns too quickly, reduce heat slightly to prevent burning.
Once the butter reaches a deep golden brown with visible browned bits at the bottom, immediately pour it through a fine-mesh strainer into a heatproof bowl to remove any milk solids. Let it cool to 100°F (about 10 minutes) while you prepare the rest of the ingredients. This butter will give your cake its signature caramelized depth and moist texture.
👨🍳 Step 2: Whisk Wet Ingredients for Light Texture
In a large mixing bowl, combine the 1.5 cups buttermilk, 1.5 cups granulated sugar, and 0.5 cup light brown sugar. Whisk until the sugars dissolve completely—this prevents grainy spots in your finished cake. Add the 2 whole large eggs, 1 tbsp pure vanilla extract, and 1 tsp vanilla bean paste, whisking gently to incorporate.
Next, slowly drizzle in the 0.5 cup vegetable oil while whisking continuously. This creates tiny air pockets that help the cake rise beautifully. The mixture should be smooth and slightly thickened. I always use room temperature ingredients here—it makes for a more even batter and better texture.
👨🍳 Step 3: Combine Dry Ingredients and Fold Gently
In a separate bowl, sift together the 2.5 cups all-purpose flour, 2 tsp baking powder, 0.5 tsp baking soda, and 0.5 tsp salt. This ensures even distribution of leavening agents throughout the batter. Make a well in the center and pour in the browned butter (now cooled to 100°F).
Using a spatula, gently fold the dry ingredients into the wet mixture just until combined—you should still see some flour streaks. Overmixing develops gluten, which can make the cake dense. The batter will be thick but pourable. Real talk: don't skip the sifting step. Those little air pockets from sifting help create that light, tender crumb we're after.
🔥 Step 4: Bake to Golden Perfection
Preheat your oven to 350°F and grease two 8-inch round cake pans (or one 9x13-inch pan) thoroughly with butter and flour. Divide the batter evenly between the pans. Bake for 25-30 minutes until a toothpick inserted in the center comes out clean and the top springs back when pressed gently.
Here's where it gets critical: don't overbake. The cake will continue cooking slightly as it cools. If the edges brown too quickly, tent loosely with foil. The ideal cake should have a golden crust with a slightly domed top that's still tender to the touch. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
⏰ Step 5: Serve at Room Temperature
This cake tastes best served at room temperature, allowing the flavors to fully develop. The brown butter flavor becomes even more pronounced as it cools. For extra richness, dust with powdered sugar or drizzle with a simple vanilla glaze made from powdered sugar and milk. Each slice should be moist, tender, and packed with that caramelized butter flavor that makes this cake so special.
Pro Tips For Making Alison Roman Brown Butter Buttermilk Cake
- Brown Butter First: The cake’s flavor hinges on that nutty, toasty butter aroma—don’t skimp on browning. Use a light-colored saucepan, melt the butter over medium heat, and watch it like a hawk: it should foam, then turn golden brown with flecks of dark sediment. If it smells like burnt popcorn, you’ve gone too far (yes, I’ve done it).
- Chill the Batter: This isn’t optional. After mixing, let the batter sit for at least 30 minutes—preferably up to 2 hours in the fridge. The buttermilk and brown butter need time to mellow, and the flour will hydrate properly. I learned this the hard way when my first batch collapsed into a dense brick because I rushed it.
- Don’t Overmix the Dry Ingredients: Whisk the flour, baking powder, and salt together just until combined—a few lumps are fine. Overworking the flour develops gluten, and this cake’s magic is in its tender crumb. Use a fork or your fingers if you’re impatient; it’s faster and just as effective.
- Use a Toothpick Test: The cake’s done when a toothpick comes out with moist crumbs, not wet batter. If it’s sticky or gummy, bake another 5 minutes—underbaking is the real enemy here. I used to pull cakes too soon, thinking they’d keep rising; they don’t. Trust the toothpick.
Essential equipment for great alison roman brown butter buttermilk cake
Butter Browning Essentials
You’ll need a light-colored saucepan (like All-Clad Stainless Steel) to monitor the butter’s color accurately. A fine-mesh strainer is critical for removing milk solids after browning—OXO Good Grips is my go-to. For precise temperature control, a candy thermometer (like Thermoworks) helps hit the 350°F golden-brown stage without burning. 🔥
Mixing Tools Matter
A whisk with a long handle (I use Cuisinart Stainless Steel) ensures smooth incorporation of wet ingredients. For dry ingredients, a sifter (like Microplane) prevents lumps and creates air pockets. A spatula with a flexible head (such as OXO Good Grips) helps fold gently without overmixing. These tools keep the batter light and tender.
Baking Pans & Prep
Use two 8-inch round cake pans (or one 9x13-inch pan) with removable bottoms for easy release. Grease pans thoroughly with unsalted butter and dust with flour—I prefer King Arthur for its reliability. A wire cooling rack (like Amazon Basics) prevents soggy bottoms while cooling. For even baking, place pans on the middle rack of your oven.
Temperature & Timing
An oven thermometer (such as Thermoworks Oven Thermometer) ensures your oven hits 350°F accurately—many ovens run hot or cold. A toothpick is essential for testing doneness. For high-altitude bakers, a baking guide (like King Arthur’s) helps adjust leavening agents. Timing is key: 25-30 minutes for round pans, 35-40 minutes for sheet pans.
Cooling & Serving
A serrated knife (like Dexter-Russell) gives clean slices, while a damp cloth helps release stuck cakes. For glaze, a pastry brush (such as Westcott) applies even coatings. Store leftovers in an airtight container (like Rubbermaid) to maintain moisture. A cake stand elevates presentation—Wilton’s are my favorite for rustic charm. 💛

Frequently asked questions
Why does brown butter make this cake taste so different?
The browning process creates over 200 flavor compounds that give the butter nutty, caramelized depth. Unlike regular butter, brown butter adds a toasty aroma and subtle sweetness that balances the buttermilk's tang. This technique transforms a basic cake into something with restaurant-quality richness.
Can I substitute regular butter for brown butter?
While you can use regular butter, you'll lose the signature caramelized flavor. For best results, brown 1 cup unsalted butter as directed, then cool it completely before using. If you're short on time, melt regular butter and add 1 teaspoon maple syrup or honey to mimic some of the caramelized notes.
How do I know when the butter is properly browned?
The butter should be a deep golden brown with visible browned bits at the bottom and a nutty aroma. It typically takes 5-7 minutes over medium heat. If it browns too quickly, reduce the heat slightly. The butter should smell like toasted nuts, not burnt. A candy thermometer can help—aim for 350°F internal temperature.
Can I make this cake in a bundt pan instead?
The batter works beautifully in a 10-12 cup bundt pan. Grease it thoroughly with butter and dust with flour. Bake at 350°F for 45-55 minutes until a toothpick comes out clean. The cake will have a beautiful domed shape with crisp edges. Let it cool completely before removing from the pan.
What's the best way to store leftovers?
Store the cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for 5 days or freeze for 3 months. The flavor actually improves after 24 hours as the brown butter notes deepen. To serve, let slices come to room temperature for 15-20 minutes before enjoying.
