This Brown Butter Bourbon Latte is warm, rich, and a little fancy without being hard to make.
Brown butter gives it a deep, toasted flavor, while brown sugar and vanilla make every sip smooth and cozy.
A splash of bourbon is great for an adult version, but the non-alcoholic version is just as good.

Why I Love This Recipe
I love making this latte when regular coffee sounds a little boring. The first time I mixed brown butter with coffee, I was surprised by how much flavor one small step added. The butter becomes toasted and nutty, and it makes the brown sugar taste almost like caramel.
Bourbon gives the latte a warm, smooth finish, but it is not required. When I want the same cozy flavor without alcohol, bourbon extract works well.
Here are a few more reasons I keep coming back to it:
- It takes about 15 minutes from start to finish.
- You only need a small amount of butter.
- Brown sugar gives it a deeper flavor than white sugar.
- You can make it with bourbon or keep it alcohol-free.
- The recipe makes two generous lattes.
- It feels special enough for a slow weekend morning.
What You’ll Need
- 2 tablespoons unsalted butter
- 2 tablespoons packed brown sugar
- 1 teaspoon vanilla extract
- 1/2 teaspoon bourbon extract for the non-alcoholic version or 2 tablespoons bourbon
- 1 1/2 cups whole milk
- 4 shots freshly brewed espresso, about 4 ounces total
- Small pinch of fine sea salt
Recipe and Instructions
Step 1: Brown the Butter
Place 2 tablespoons unsalted butter in a small, light-colored saucepan. Set it over medium-low heat.
Let the butter melt. Keep cooking for about 3 to 5 minutes, gently swirling or stirring it. First it will foam. Then you will see little golden-brown bits forming on the bottom.
As soon as the butter smells toasted and nutty and the bits are golden brown, move to the next step. Do not let them turn black.
Step 2: Make the Brown Butter Syrup
Keep the saucepan over low heat. Add 2 tablespoons packed brown sugar and a small pinch of fine sea salt to the 2 tablespoons browned butter from Step 1.
Whisk for about 30 seconds. The mixture will look glossy and thick. The sugar does not need to dissolve completely yet.
Step 3: Add the Milk
Slowly pour 1 1/2 cups whole milk into the saucepan.
Whisk well. Heat over medium-low heat for 3 to 4 minutes, until the milk is hot and steaming. Do not let it boil.
Remove the saucepan from the heat.
Step 4: Add Vanilla and Bourbon Flavor
Once the saucepan is off the heat, stir 1 teaspoon vanilla extract into the hot brown butter milk.
For the non-alcoholic latte, stir in 1/2 teaspoon bourbon extract.
For the alcoholic version, use 2 tablespoons bourbon instead. Keeping the pan off the heat helps keep more of the bourbon flavor and alcohol in the drink.
Step 5: Froth the Milk Mixture
Use a handheld milk frother to froth the warm mixture for about 30 to 45 seconds. You want small, soft bubbles and a creamy layer of foam.
You can also carefully whisk it by hand if you do not have a frother.
Step 6: Brew the Espresso
Brew 4 shots of espresso, about 4 ounces total. Divide the espresso evenly between two clear round glass mugs, giving each mug about 2 ounces espresso.
Step 7: Build and Serve the Lattes
Divide all of the warm, frothed brown butter milk mixture evenly between the two mugs containing the 4 shots espresso.
Pour slowly so the coffee and milk mix together, then spoon the remaining foam over each latte.
Serve right away while warm with a light, even sprinkle of golden-brown sugar across the surface.
Why This Recipe Works (Quick Science)
Browning butter changes its flavor. As butter cooks, its milk solids toast. This is called the Maillard reaction. It creates nutty, caramel-like flavors that taste great with coffee.
Brown sugar contains molasses, so it has a deeper flavor than plain white sugar. That flavor pairs well with browned butter and espresso.
A tiny pinch of salt also matters. It cuts some of the sweetness and helps the caramel, vanilla, and coffee flavors stand out.
Finally, frothing the warm milk mixture adds tiny air bubbles. Those bubbles make the latte feel lighter and creamier when you drink it.
Pro Tips
- Use a light-colored saucepan. It is much easier to see when the butter turns golden brown.
- Watch the butter closely. Brown butter can go from golden to burned very fast.
- Keep the milk below a boil. Boiled milk can develop a cooked flavor and will not be as pleasant to froth.
- Add vanilla and bourbon flavoring after removing the saucepan from the heat. This keeps their flavor stronger.
- Taste before adding more sugar. The 2 tablespoons of brown sugar make a balanced latte, but you can adjust the next batch to your liking.
Tools You’ll Need
- Small light-colored saucepan
- Silicone spatula
- Small whisk
- Measuring spoons
- Liquid measuring cup
- Espresso machine or another espresso maker
- Handheld milk frother
- 2 clear round glass mugs
Substitutions and Variations
- Non-alcoholic: Use 1/2 teaspoon bourbon extract instead of 2 tablespoons bourbon. Check the extract label if you need a product that contains no alcohol at all, since some extracts use alcohol as a carrier.
- No bourbon flavor: Leave it out completely. You will still have a delicious brown butter vanilla latte.
- Milk: Whole milk gives the creamiest texture. Oat milk is a good dairy-free choice and froths well.
- Sweeter: Add another 1 to 2 teaspoons brown sugar.
- Less sweet: Reduce the brown sugar to 1 tablespoon.
- Coffee: If you do not have espresso, use about 1/2 cup very strong brewed coffee.
- Extra cozy: Add a small pinch of cinnamon to the milk.
Make-Ahead Tips
You can make the brown butter milk mixture ahead of time. Let it cool, place it in a sealed container, and refrigerate it for up to 2 days.
When you want a latte, gently warm the mixture on the stove. Froth it, then add it to freshly brewed espresso.
For the best flavor and foam, brew the espresso right before serving.
Common Mistakes
- Burning the butter: Stop cooking once the milk solids are golden brown and smell nutty. Black specks usually mean the butter has burned.
- Using heat that is too high: Medium-low heat gives you much more control.
- Boiling the milk: Heat it until steaming, not bubbling hard.
- Adding bourbon over an open flame: Bourbon is flammable. Remove the pan from the burner before adding it.
- Waiting too long to drink it: A latte tastes best right after the espresso is brewed and the milk is frothed.

What to Serve With
This latte is rich, so simple baked treats work especially well with it.
- Butter croissants
- Banana bread
- Blueberry muffins
- Cinnamon toast
- Shortbread cookies
- Apple muffins
- Pumpkin bread
- A simple breakfast sandwich
Leftovers and Storage
If you have leftover brown butter milk mixture, refrigerate it in an airtight container for up to 2 days.
Warm it gently on the stove and froth it again before serving. Do not boil it.
For the best latte, make fresh espresso instead of storing a fully mixed latte. Espresso loses much of its fresh flavor after it sits.
FAQ
Q: Does this latte taste strongly like butter?
A: No. Browning the butter gives it more of a toasted, nutty, caramel-like flavor.
Q: Can I make it without bourbon?
A: Yes. Use 1/2 teaspoon bourbon extract for bourbon-style flavor, or leave it out completely.
Q: Is bourbon extract always alcohol-free?
A: No. Some bourbon-flavored extracts contain alcohol. If you need a truly alcohol-free drink, read the bottle and choose an extract specifically labeled alcohol-free.
Q: Can I use regular coffee instead of espresso?
A: Yes. Use about 1/2 cup very strong coffee for the whole recipe. Espresso will give you a richer coffee flavor.
Q: Can I use oat milk?
A: Yes. Barista-style oat milk is especially good because it usually makes a nice foam.
Q: Why did my brown butter burn?
A: The heat was probably a little too high or it cooked for too long. Once you see golden-brown bits and smell a nutty aroma, it is ready.
Q: Can I make this iced?
A: Yes. Let the brown butter mixture cool first. Fill two glasses with ice, add the espresso, then pour the cooled mixture over it.
Final Thoughts
This Brown Butter Bourbon Latte turns a few simple ingredients into something that feels like a coffee shop treat. The browned butter is the little trick that makes it special. It adds a warm, toasted flavor that works beautifully with brown sugar, vanilla, and espresso.
