Bourbon milkshake
As a last hurrah before summer is over, I am so excited to share this bourbon milkshake recipe!
It's a classic vanilla milkshake spruced up with a shot (or two) of bourbon, a drizzle of homemade bourbon caramel sauce, and a topping of whipped cream (which is a MUST-HAVE for milkshakes, don't you think??).
And it's so so good.

Our 5 year old son walked in on us drinking these milkshakes after I took these pictures and asked if he could have some... we both immediately answered: NOPE!!

Bourbon caramel sauce
The boozy caramel sauce is really the only semi-complicated part of this recipe, so if you really want to make this a quick milkshake, just get regular caramel sauce and us that. Otherwise, here are the ingredients to make your own buttery bourbon caramel sauce:
- 1 cup sugar (granulated cane sugar)
- ¼ cup water
- 1 pinch salt (or use more for a salted caramel sauce!)
- 6 tablespoons unsalted butter, sliced into ½ - ¾ inch pieces
- ½ cup heavy whipping cream
- 1 teaspoon vanilla extract
- ½ shot bourbon (1.5 tablespoons), or use whiskey or even spiced rum
You'll also need a silicone spatula, a whisk, and a medium-sized saucepan (about 3-4 quarts) to make caramel sauce. Even though the recipe only makes about 1.5 cups caramel sauce, it does rise a lot in the pot as it cooks, so you need a bigger pot than you think.

How to make bourbon caramel sauce
Step 1: In a medium saucepan (about 3 quarts), combine the sugar, water, and salt. Heat over medium-low heat, stirring until the sugar melts and stops clumping together. Lower the heat to low and continue to heat without stirring much for 7-10 minutes, or until the mixture turns a caramel-honey color. Use a spatula if needed to brush any caramelized sugar from the sides of the pan into the melted mixture, but don't worry too much about the caramelized crystals. Keep an eye out on the mixture because it can burn quickly right around when it turns from clear to a caramel color. Remove from heat as soon as it's a caramel color.

Step 2: CAREFULLY add the sliced butter and whisk together immediately to prevent the caramel sauce from rising up too much. Continue stirring until all the butter is incorporated.

Step 3: Stir in the heavy cream, vanilla extract, and bourbon. Whisk continuously until all the heavy cream has been incorporated and you have a smooth mixture.

Step 4: Allow to cool for 10-15 minutes, then pour into a jar to store. The sauce will thicken as it cools.

How to store caramel sauce
This caramel sauce needs to be stored in the fridge because it is made with heavy cream. It will keep well in the fridge for weeks. The sauce will thicken a lot in the fridge. You can take it out of the fridge 15-20 minutes before serving to let it warm up, or you can microwave for just a few seconds to warm it up and make it perfectly drizzle-able.

Boozy milkshake ingredients
The general ratio of ice cream to milk I like to use for milkshakes is 3 parts ice cream to 1 part milk, but of course you can adjust to your liking, depending on whether you like a super thick milkshake or one that you can easily drink with a straw. The recipe below makes 2 milkshakes, and you can scale up or down, as needed.
- 1.5 cups vanilla bean ice cream
- ½ cup milk (whole milk or 2% is best for the richest milkshake, but any kind of milk will do if you don't have those)
- 1 teaspoon vanilla extract (or try using vanilla bean powder for extra vanilla flavor and specks)
- 1 shot bourbon (or use more for a more boozy milkshake!)
- 1 tablespoon bourbon caramel sauce for drizzle
- whipped cream for serving
Grab your blender and 2 glasses!!

Instructions
Step 1: Use a spoon to drizzle the caramel sauce on the inside of your glasses or cups, making sure to get the walls of the glass so it's not all on the bottom. Place the glasses in the fridge while you prepare the milkshake to keep them cold.
Step 2: Combine the ice cream, milk, vanilla extract, and bourbon in a blender and process until completely smooth.
Step 3: Divide the milkshake between the caramel-drizzled glasses. Add some whipped cream and drizzle with more caramel sauce on top. Use a straw to stir the caramel into the milkshake and enjoy immediately!

What to do with leftover bourbon caramel sauce
This recipe makes a LOT of caramel sauce, and you only need a tablespoon or two for the milkshakes, so here are some ideas for how to use up the rest of the caramel sauce:
- Drizzle it on apricot vanilla ice cream
- Spoon it on this creamy banana pudding before digging in
- Drizzle it on these bourbon pecan pie bites
- Generously spoon some over this apple crisp
- Use it as pancake syrup for brunch (try it with churro pancakes!!)
- Drizzle it over buttermilk blini
- Drizzle it on top of mini apple pie cups or these air fryer baked apples
- Spoon some over Greek yogurt for a late night snack
- Drizzle it on top of brownies

Bake with it and use it anywhere you can use a drizzle of sweet caramel sauce.
