Why I Love This Recipe
Okay, here’s the thing—I love dessert cocktails, but I want them to taste like dessert first. This milkshake delivers. I first made this after a rainy fall day when I just wanted to chill out and watch a movie. I didn’t want to bake. I didn’t want to cook. I just wanted something easy and indulgent. Since then, it’s been a repeat favorite.

How to Make Toasted Marshmallow Baileys Milkshake
Step 1: Toast the Marshmallows
Place 1 cup mini marshmallows on a parchment-lined sheet pan. Broil on high for 1-2 minutes until golden brown and toasted.
Step 2: Add Ice Cream to Blender
Scoop 2 cups vanilla ice cream into the blender.
Step 3: Add Toasted Marshmallows
Add the warm, toasted mini marshmallows from the pan into the blender.
Step 4: Add Baileys and Milk
Pour 1/3 cup Baileys Irish Cream and 1 cup whole milk into the blender.
Step 5: Blend Until Smooth
Blend everything on high for 30–45 seconds until smooth and creamy.
Step 6: Optional – Caramel Drizzle Inside Glass
Drizzle caramel sauce along the inside walls of two glasses before pouring in the milkshake.
Step 7: Pour and Serve
Pour the milkshake into your prepared glasses. Top with whipped cream and extra toasted marshmallows if you like.
Leftovers & Storage
This one’s best served fresh, but if you’ve got extra, keep it in the freezer in an airtight container. Re-blend with a splash of milk to loosen it up before serving.
Why This Recipe Works (Quick Science)
Toasting the marshmallows caramelizes their sugars, bringing out a deeper, smoky-sweet flavor that balances the richness of the Baileys. Blending them while warm helps them emulsify into the ice cream, creating a silky texture. The cold milk keeps it drinkable, and the ice cream gives it body.
Common Mistakes
- Burning the marshmallows – They go from golden to black fast. Watch the broiler!
- Not blending long enough – You want it super smooth. No marshmallow chunks.
- Using light or low-fat milk – It waters down the shake.
What to Serve With
- A chocolate chip cookie on the side
- A salty snack like pretzels for contrast
- A small cheese plate for a fancy touch
FAQ
Can I make it without alcohol?
Yes! Just leave out the Baileys and add an extra splash of milk or a bit of marshmallow syrup.
Can I use marshmallow fluff instead of toasted marshmallows?
You can, but it won’t have that toasted flavor.
Do I have to use vanilla ice cream?
Nope—try caramel or chocolate for a twist.
