Cherry Vanilla Dr Pepper Bourbon Old Fashioned

Some cocktails stick to tradition, while others take a classic and give it a personality all their own. This Cherry Vanilla Dr Pepper Bourbon Old Fashioned does exactly that. It combines the rich, oaky character of bourbon with the nostalgic cherry, vanilla, and spice notes of Dr Pepper, creating a drink that's familiar but anything but ordinary.

The secret to this cocktail is a homemade Dr Pepper reduction syrup. By slowly simmering the soda with a little sugar, you concentrate its signature flavors into a sweet, flavorful syrup that blends beautifully with bourbon. A couple of dashes of Angostura bitters bring everything together, adding warmth and complexity without overpowering the whiskey.

Unlike a traditional Old Fashioned that relies on simple syrup or a sugar cube, this version introduces layers of caramel, cherry, vanilla, and subtle spice. The result is a smooth, bourbon-forward cocktail with just enough sweetness to balance the whiskey. A large ice cube keeps everything chilled while allowing the flavors to develop as you sip.

Whether you're entertaining friends, relaxing after a long day tending the smoker, or looking for something different to serve alongside a backyard BBQ feast, this cocktail deserves a spot in your rotation. Finish it with a maraschino cherry and a fresh orange twist, and you've got a drink that looks as good as it tastes.

Ingredients

For the Dr Pepper Reduction Syrup

1 cup Dr Pepper
1/4 cup granulated sugar

For the Bourbon Old Fashioned

2 oz bourbon
1/2 oz homemade Dr Pepper reduction syrup
2 dashes Angostura bitters
1 large ice cube
1 maraschino cherry, for garnish
1 orange peel twist, for garnish

Instructions

Make the Dr Pepper Reduction Syrup

Pour 1 cup of Dr Pepper into a small saucepan.
Add 1/4 cup granulated sugar and stir to combine.
Place the saucepan over medium-low heat and bring to a gentle simmer.
Allow the mixture to simmer for approximately 10–15 minutes, or until reduced by about half and slightly thickened.
Stir occasionally to prevent the sugar from sticking or burning.
Remove from the heat and allow the syrup to cool completely.
Transfer to a clean, airtight container and refrigerate until ready to use.

Prepare the Bourbon Old Fashioned

Fill a cocktail mixing glass with ice.
Pour in 2 oz of your favorite bourbon.
Add 1/2 oz of the cooled Dr Pepper reduction syrup.
Add 2 dashes of Angostura bitters.
Stir gently for 20–30 seconds until thoroughly chilled and properly diluted.

Serve and Garnish

Place a large ice cube into a chilled rocks glass.
Strain the bourbon mixture over the ice.
Express the oils from a fresh orange peel over the surface of the cocktail.
Twist the orange peel and place it into the glass.
Garnish with a maraschino cherry.
Serve immediately and enjoy.

Tips for the Perfect Dr Pepper Old Fashioned

Choose a good bourbon: A bourbon with notes of caramel, vanilla, and oak works especially well with the Dr Pepper syrup. A higher-proof bourbon can help balance the sweetness.
Don't over-reduce the syrup: The syrup should be slightly thickened but still pourable. Reducing it too far can create an overly sweet, sticky concentrate.
Use a large ice cube: Larger ice cubes melt more slowly, keeping the cocktail chilled without watering it down too quickly.
Adjust the sweetness: Start with 1/2 oz of syrup. If you prefer a less sweet cocktail, reduce the amount to 1/4 oz.
Use a quality cherry: Luxardo-style cocktail cherries add a rich, dark cherry flavor that complements the bourbon beautifully.
Don't skip the orange twist: Fresh orange oils brighten the cocktail and balance the deeper caramel and spice notes.

Choosing the Right Bourbon

The bourbon you choose can completely change the character of this drink. A sweeter wheated bourbon will highlight the vanilla and caramel notes, creating a softer, smoother cocktail.

For a bolder experience, reach for a high-rye bourbon. The additional peppery spice provides a nice contrast to the cherry and vanilla sweetness of the Dr Pepper reduction.

If you're looking for something with a little more backbone, a bottled-in-bond bourbon is an excellent choice. Its higher proof helps the whiskey remain the star of the cocktail instead of getting lost behind the syrup.

Make It Your Own

Want to give this Old Fashioned an extra layer of flavor? Try adding a few drops of chocolate bitters alongside the Angostura bitters. The chocolate notes work surprisingly well with Dr Pepper's cherry and vanilla profile.

For a deeper cherry character, add a bar spoon of syrup from a jar of premium cocktail cherries. Just remember to slightly reduce the Dr Pepper syrup to keep the sweetness balanced.

You can also swap the bourbon for rye whiskey if you prefer a spicier, drier finish. Rye brings a peppery edge that contrasts beautifully with the sweet reduction.

Storage and Make-Ahead Tips

Store leftover Dr Pepper reduction syrup in a clean, airtight container in the refrigerator.
Use refrigerated syrup within approximately 1 week.
Prepare the syrup ahead of time to make cocktail assembly quick and easy when entertaining.
Keep the bourbon, syrup, and bitters separate until you're ready to mix and serve.
Always use fresh ice and garnish each cocktail just before serving.

Final Thoughts

The Cherry Vanilla Dr Pepper Bourbon Old Fashioned proves that a classic cocktail doesn't have to follow every rule to be outstanding. With rich bourbon, homemade soda reduction, aromatic bitters, and a bright citrus finish, this drink delivers a balance of nostalgia and sophistication.

It's sweet, spiced, bourbon-forward, and just a little rebellious. Pour one over a big cube of ice, kick back, and enjoy a different take on an old favorite.
