A few summers ago, my husband and I visited a little seaside town while on our way to see our eldest daughter. We ducked into a tiny boardwalk café to escape the afternoon sun, and I noticed a chalkboard sign advertising “Butterbeer Milkshakes.” I couldn’t resist.
One sip of that smooth butterscotch sweetness, with a hint of warmth from the spirits, felt like the perfect mix of nostalgia and indulgence. I remember leaning across the table, insisting he try it, and the two of us spent the rest of the afternoon strolling the pier, sharing that single frosty shake and watching the waves roll in.
That memory stuck with me, and I’ve been recreating my own version ever since—one that captures that same magic but is easy to whip up at home. Now, it’s become a special treat we make for family movie nights or after-dinner desserts with friends. My grandchildren get the non-boozy version, while the adults enjoy the extra little kick that makes it feel a bit more special.
The best part about this milkshake is that you don’t need fancy equipment or rare ingredients. Everything comes together in minutes, and it’s as much fun to make as it is to drink. Each time I blend one up, the sweet, buttery aroma of butterscotch reminds me of warm summer evenings and that first seaside café adventure.

This Boozy Butterbeer Milkshake is a creamy, sweet blend of vanilla ice cream, butterscotch syrup, and a splash of spiced rum or whiskey. Topped with whipped cream and a drizzle of syrup, it’s an easy, crowd-pleasing dessert drink perfect for parties or cozy nights in.
Key Ingredients

Tools Needed

Cooking Instructions
Step 1: Blend the base
Add the vanilla ice cream, milk, butterscotch syrup, and spiced rum or whiskey into a blender.
Step 2: Blend until smooth
Process on high speed for about 30 seconds or until thick, creamy, and completely smooth. If you like a thinner milkshake, add another tablespoon or two of milk.
Step 3: Serve and garnish
Pour the milkshake into tall dessert glasses. Top generously with whipped cream and drizzle extra butterscotch syrup over the top. Serve right away while it’s cold and frothy.
Troubleshooting Tip: If the milkshake is too runny, add a few extra scoops of ice cream and blend again. If it’s too thick for your blender to process, add a splash of milk at a time until it reaches the desired consistency.

Mistakes to Avoid & Solutions
Using melted ice cream: If the ice cream is too soft, the milkshake can become watery. Keep it frozen until ready to use.
Over-blending: Blending too long can cause the milkshake to thin out. Stop as soon as it’s smooth.
Adding too much liquid at once: Start with the listed milk amount; you can always add more if needed.
Skipping the garnish: The whipped cream and syrup drizzle elevate the flavor and presentation—don’t skip them!
Serving warm glasses: Chill the glasses beforehand to keep the milkshake cold for longer.
Serving and Pairing Suggestions
Serve in chilled tall glasses for the best texture.
Pair with chocolate-dipped pretzels or buttery shortbread cookies for a sweet-salty contrast.
For a themed party, garnish with golden sugar sprinkles or a cinnamon stick for stirring.
Offer a non-alcoholic version for kids by omitting the rum or whiskey.
Perfect as an after-dinner dessert or served at a backyard barbecue for adults.
Storage and Reheating Tips
Milkshakes are best enjoyed fresh.
If you must store, freeze the milkshake in an airtight container for up to 2 days. Let it thaw for about 10 minutes and re-blend before serving.
Keep whipped cream separate until ready to serve to maintain its fluffiness.
FAQs
Can I make it without alcohol?
Absolutely—just skip the rum or whiskey. It’s still deliciously creamy and sweet.
What’s the best non-dairy alternative?
Swap dairy ice cream for coconut or almond-based ice cream and use almond or oat milk for a creamy result.
Can I prepare it ahead of time?
It’s best made fresh, but you can blend it ahead and freeze. Re-blend before serving to restore creaminess.
Is there a substitute for butterscotch syrup?
Caramel syrup works well and adds a slightly richer flavor.
How do I adjust the sweetness?
Add or reduce the syrup to suit your taste. Start with the listed amount and adjust after blending.

Chill the glasses before serving for a milkshake that stays frosty longer.
For extra richness, replace 2 tablespoons of milk with heavy cream.
A pinch of sea salt in the blender enhances the butterscotch flavor.

Final Thoughts
This milkshake is simple enough for a quick weeknight dessert but special enough to serve at parties. My grandchildren love watching the blender whirl the ingredients together, and my husband still claims that first seaside café version was unbeatable, though I’m convinced this one comes pretty close.
I’ve grown to love how easy it is to customize, whether I’m adding a pinch of salt for depth or dressing it up with festive garnishes for the holidays. Sharing it with friends around the table or sipping it slowly on the porch during summer sunsets always makes the moment feel a bit more magical.
