This brown butter bourbon cocktail is full of buttery flavor!


We wanted a slightly fall cocktail that was a little subtle. Not the big screaming flavors that are usually associated with fall, apple, pumpkin, maple. We have tried butter fat washed cocktails before, but wanted to have a different flavor in this one.

What is Brown Butter Made Of?

Brown butter, is made by cooking butter long enough to turn the milk solids brown while cooking out any water present.

We knew that browned butter would give us the flavor we were hunting after. With the heaviness of the browned butter, we didn’t add much simple syrup. The unctuousness of the bourbon didn’t need much to sweeten it up. We added in chocolate coffee bitters to give it more of dessert and breakfasty feel.


Watch carefully as browned specks begin to form at the bottom of the pan. The butter should have a nutty aroma. Should take about 2-3 minutes for the butter to brown. Remove from heat and pour in a bowl. This stops the butter from cooking further, keep whisking to cool and finish. It can be easy to overcook brown butter, and it can quickly burn, so watch carefully!

What Ingredients are Needed for the Brown Butter Old Fashioned?

  • Butter
  • Bourbon
  • Chocolate Coffee Bitters

What is Fat Washing?

To fat wash alcohol, you just add a liquid like oil or melted butter to a spirit at room temperature. Let it sit for a bit, then chill everything in the freezer until the fat solidifies and can be skimmed off.

This one is so flavorful and we hope you will try it out. Easy to make, the hardest part is fat washing the bourbon, so you do have to plan ahead slightly. But to make the actual cocktail is super fast and makes for a tasty tipple.
