Fall is the perfect time for cocktails that feel both classic and seasonal, and few drinks do that better than an Old Fashioned. This year, I took my love for Pumpkin Spice Latte syrup—yes, the same syrup I use in coffee, pancakes, and even granola—and added it to this timeless cocktail. The result? A cozy, warm, slightly sweet drink that’s perfect for autumn evenings.

I’ve always loved using one ingredient across different meals and courses. It’s a simple way to elevate your cooking without cluttering your kitchen. A solid syrup like this doesn’t just sweeten—it adds depth, warmth, and an “out-of-the-box” quality that makes every dish or drink feel special. That’s exactly what happens in this Pumpkin Spice Old Fashioned.

Why Pumpkin Spice Works in an Old Fashioned

Most people think pumpkin spice only belongs in coffee, desserts, or baked goods. But a few dashes of this aromatic blend, or a spoonful of homemade PSL syrup (click here for the recipe), can completely transform a cocktail.

Here’s the magic: the syrup provides subtle sweetness and a layer of warm fall spices—cinnamon, nutmeg, cloves, cardamom, and allspice—without overpowering the whiskey. It enhances the rich, boozy base and makes every sip feel cozy and refined. The pumpkin itself is just there to add body; the spices do the flavor heavy-lifting.

Step-by-Step Instructions

Fill a rocks glass with ice.
In a separate mixing glass, stir bourbon, PSL syrup, and bitters with ice to chill and combine flavors.

Sip slowly and savor the warm fall spices balanced with rich whiskey notes.

Tasting Notes

The first sip is classic Old Fashioned—rich, boozy, slightly sweet, and complex. Then the pumpkin spice comes in as a warm, subtle wave of cinnamon, nutmeg, and cloves. It complements without taking over, adding a seasonal twist that feels elevated yet familiar.

This cocktail feels like autumn in a glass: cozy, sophisticated, and approachable all at once.

Tips for the Perfect Pumpkin Spice Old Fashioned

Use a quality whiskey: Bourbon adds sweetness, rye brings spicier notes—both pair beautifully with the pumpkin spice syrup.
Adjust sweetness: If you prefer less sweetness, reduce the syrup to ¼ oz.
Fresh orange peel: Expressing oils over the drink adds brightness and aroma.
Cinnamon stick garnish: Optional, but it doubles as a stirrer and adds a subtle spicy aroma.
Batch for parties: Pre-mix bourbon, syrup, and bitters in a bottle. Pour over ice and garnish when serving.

Pairing Suggestions

This cocktail pairs beautifully with fall foods:

Savory: Roast chicken, glazed ham, or spiced nuts.
Sweet: Pumpkin bread, apple pie, or chocolate truffles.
Snack: Cheese boards with aged cheddar, gouda, or creamy brie.

The layered spice of the PSL syrup complements both sweet and savory notes, making this cocktail versatile for any gathering.

FAQs

Q: Can I use store-bought pumpkin spice syrup?
Yes! But homemade syrup (recipe here) adds a richer, more balanced flavor with less artificial sweetness.

Q: Can I make this with non-alcoholic whiskey alternatives?
Absolutely. A non-alcoholic bourbon-style spirit or even a chilled black tea base can create a warm, cozy mocktail version.

Q: How long does leftover syrup last?
Store in a sealed glass jar in the fridge for up to two weeks. Shake before using, as spices and pumpkin may settle. (Check these jars)

Q: Can I add other spices?
Yes! A small pinch of ginger or star anise can add complexity. Start small—you don’t want to overpower the whiskey.

Why I Love Using Ingredients Across Recipes

What I love about this cocktail is that it’s built around one ingredient I already love using: Pumpkin Spice Latte syrup. I can use the same jar to sweeten coffee, drizzle over pancakes, stir into oatmeal, or mix into cocktails. It saves time, reduces waste, and makes my cooking feel creative without being complicated.

A solid syrup is like a flavor tool in your kitchen arsenal. It elevates everything it touches. And in the case of this Pumpkin Spice Old Fashioned, it transforms a classic cocktail into something uniquely fall-inspired.

Entertaining Tips

Batch cocktails: Pre-mix bourbon, syrup, and bitters for easy pouring at parties.
Use large ice cubes: They melt slower, keeping your drink chilled without diluting flavor. (Large ice cube molds)
Prep garnishes: Slice orange peels and cinnamon sticks in advance for a polished look.
