About this Cake
Kentucky Bourbon Cake (sometimes called Kentucky Bourbon Butter Cake) is a traditional dessert that celebrates one of the state’s most important exports.



The export is bourbon, not butter. 😊And you can learn even more about what it is and what makes it so very special at the Kentucky Distillers’ Association website, or this exceptionally beautifully-written Bourbon for Beginners article from the Cocktail Contessa Website. Those websites are an incredible and comprehensive resource for bourbon beginners and enthusiasts, and y’all already know how I feel about deep diving into your ingredients to understand how they impact your outcomes.
While each bourbon has distinctive notes that make it stand alone from the others, this cake really highlights the caramel and vanilla flavor notes that are common to many different types of bourbon. And boy does it feature them prominently! In the cake batter, there’s 63 grams (¼ cup) of bourbon infused in the brown butter (and thus, in the cake batter), aerated through the creaming process so that it more prominently features the nuanced caramel and vanilla notes in this special spirit. (And, depending on the specific bourbon, you could also enliven the dried fruit or spice notes as well!)
In the Bourbon Butter Sauce, we go for a full half cup (125 grams) of bourbon. And here’s where it gets really cool. You can either add that bourbon right at the end of the cook time if you want the strongest bourbon flavor, or, you can add the bourbon at the beginning of the cook time if you want to feature the more mellow bourbon notes without the alcohol bite. I prefer the latter, but I’ve tried the former and it is some kinda good. ❤️
All in all, this cake is an exceptional representation of the beautiful flavor striations found in bourbon. And I’m excited to hear your experiences with this uniquely traditional cake.

Brown Butter Kentucky Bourbon Cake: The Key Ingredients
Making delicious cakes is equal parts art and science. Here are some bite-sized bits about the key ingredients in this amazing cake!
Brown Butter isn’t just melted butter—it’s butter that’s been transformed through heat into a nutty, deep caramelized flavor. The milk solids undergo the glorious Maillard reaction (that’s food science for “delicious browning”), creating those golden specks that distribute throughout your cake. When you add bourbon to cooled brown butter, you’re creating a flavor foundation that will make your taste buds dance!
Bourbon brings so much more than an alcoholic bite to this cake—it contributes complex vanilla and caramel notes that marry perfectly with the brown butter. During baking, most of the alcohol evaporates, removing that famous first-sip Kentucky Chew and leaving behind those gorgeous vanilla and caramel flavors that make Kentucky bourbon famous worldwide.

Buttermilk provides the perfect tangy counterpoint to the richness of this cake, while its proteins help create that moist crumb we want in this cake. The acidity works together with the baking soda to ensure that your cake rises beautifully into the impressive beauty that she is meant to be.
Kosher Salt is the unsung hero that makes every other flavor in this cake pop. It balances the sweetness and enhances the caramel and vanilla notes, creating a sophisticated depth that keeps everyone coming back for “just one more slice.” (spoiler alert: they never, ever take just one more slice.)
Vanilla brings its own extraordinary dimension, especially if you use real vanilla beans. Those distinctive flecks aren’t just pretty—they’re concentrated flavor bombs that elevate this cake from delicious to unforgettable.

The Techniques That Make This Cake So Special
How to Get Perfect Brown Butter for this Recipe
Browning butter isn’t just a technique—it truly changes butter by separating the milk solids from the fats, toasting those milk solids, and adding extremely delicious depth to your final baked goods.
The trickiest part about brown butter is knowing when to stop! Too little time and you’ll miss out on those deep, nutty flavors. Too much time and you’ll have too-dark butter solids that add an acrid, burnt taste to your baked goods (I’ve tried this and do NOT recommend).
Brown butter will go from yellow, to melted, to very golden, and then foamy. Don’t let the foam fool you! Those brown bits might be lurking just below the surface.






My Butter-Browning Tips:
- Use a light-colored or stainless steel pan if possible—it makes those golden milk solids easier to spot. Instead of a pot, I actually use a stainless steel sauté pan for perfect results!
- The process seems slow until suddenly it’s not! That foam stage can last several minutes, but once you see those milk solids turning amber, you’re seconds away from perfect or burnt.
- Have your heat-proof container ready to go before you start—when it’s time to stop, you need to move quickly!

The Bourbon Butter Sauce: Finding Your Flavor Sweet Spot
This sauce is where you get to customize your bourbon experience! I’ve made this cake several times, and I’ve learned that how you add the bourbon makes a tremendous difference in your outcome. As always, it’s a matter of taste!
Adding bourbon early in the cooking process mellows its character, while adding it at the end preserves more of that distinctive bourbon kick in the final cake. Neither is wrong—it’s about your preference!

Sauce Success Secrets:
- Keep the heat gentle—rapid boiling can cause crystallization.
- When reducing the sauce, patience is key; rush this step and you might end up with something closer to thick bourbon caramel than sauce (though that doesn’t sound half bad).
- Adding the bourbon early creates a more balanced flavor if you don’t want a liquor-soaked cake.
Salted Caramel: The Decadently Dramatic Final Touch
Let’s be honest—with all of the scary warnings in caramel recipes, caramel can seem like a dangerously daunting kitchen task! But once you’ve mastered this technique, you’ll find yourself wanting to add caramel to everything. It’s an amazingly simple technique that helps add rich flavor to whatever you’re making, and with caution, you can achieve the most delicious results.
The melting sugar stage is where most beginners get nervous. Those clumps that form are totally normal! Just keep gently whisking, and they’ll smooth out as the caramelization continues.

Caramel Confidential:
- Use a larger pot than you think you need—the mixture bubbles dramatically when adding butter and cream.
- That balloon whisk I recommend? It’s not just a suggestion. Metal handles conduct heat and can leave you with toasty fingers!
- The color of your caramel determines its flavor—lighter amber gives you sweet notes while deeper amber introduces those complex, almost coffee-like undertones.
