Toasted Marshmallow Milkshake Recipe

This Toasted Marshmallow Milkshake is a thick, creamy chocolate marshmallow shake made with chocolate ice cream, marshmallow fluff, vanilla, and golden toasted marshmallows. It has all the gooey, slightly caramelized flavor of a campfire marshmallow blended into an easy frozen dessert you can make right in your kitchen.

If s’mores and an old-fashioned chocolate milkshake had a ridiculously delicious summer fling, this would be it.

You can toast the marshmallows under the broiler, with a kitchen torch, or over a fire pit. Blend the darkest toasted marshmallows right into the shake, save the pretty golden ones for the top, and add graham cracker crumbs if you want to take it straight into s’mores territory.

Why You’ll Love This Toasted Marshmallow Milkshake

I have a weakness for desserts that are just a little excessive, and this marshmallow milkshake understands the assignment.

The secret is using marshmallows twice. Some are toasted deeply and blended into the shake, where their caramelized edges add a subtle campfire flavor. The rest are toasted until golden and gooey and piled on top.

• It tastes like summer camp. Toasting the marshmallows gives you flavor that plain marshmallow fluff alone cannot create.
• It is easy. Toast, blend, pour, and garnish.
• You control the thickness. Start with less milk for a spoonable shake and add more until it is exactly how you like it.
• No campfire is required. Your oven broiler works beautifully.
• It is easy to turn into a s’mores milkshake. Graham cracker crumbs and chocolate syrup are all it takes.

And if over-the-top milkshakes are your particular brand of happiness, save my Donut Milkshake Recipe for next time.

Ingredients for a Marshmallow Milkshake

You only need a handful of ingredients to make this chocolate marshmallow milkshake. Use an ice cream you genuinely like because its flavor makes up most of the shake.

• 1-pound bag jumbo marshmallows, divided: Toast one batch more deeply for blending and a second batch lightly for topping. You can also use my Homemade Marshmallows.
• 2 cups chocolate ice cream: Classic chocolate gives you that nostalgic ice-cream-shop flavor. Dark chocolate makes the shake richer.
• 1 to 2 cups milk: Start with about 1 cup and add more as needed. Whole milk produces the richest texture, but 2% also works.
• 1/2 cup marshmallow fluff: This distributes sweet marshmallow flavor throughout the entire shake.
• 1/2 teaspoon vanilla extract: Vanilla rounds out the chocolate and toasted-marshmallow flavors.
• Graham cracker crumbs, optional: Add these if you want a s’mores-style finish.

My thick-shake rule: You can always add more milk. You cannot politely ask it to leave once it is in the blender. Start thick and thin the milkshake a little at a time.

How to Make a Toasted Marshmallow Milkshake

Want to see just how easy this gooey, chocolatey milkshake comes together? This quick video walks you through toasting the marshmallows, blending the shake until thick and creamy, adjusting the consistency, chilling the glasses, and finishing everything with toasted marshmallows and a s’mores-inspired garnish.

How to Make a Toasted Marshmallow Milkshake

1. Toast the Marshmallows for Blending

Preheat your broiler and line a baking sheet with foil. Arrange half of the jumbo marshmallows in a single layer.

Broil until they are deeply golden and toasted in spots, watching them constantly. This batch can get fairly dark because those caramelized edges are going into the blender and giving our marshmallow shake its campfire flavor.

Remove them from the baking sheet and allow them to cool slightly.

2. Toast the Marshmallows for Topping

Place the remaining marshmallows on the prepared baking sheet and return them to the broiler.

This time, toast them only until they are puffed and beautifully golden. These are the show-off marshmallows going on top of the finished shakes.

And do not walk away.

Broilers do not believe in second chances. One minute you have perfectly golden marshmallows. The next you have tiny charcoal pillows and a smoke detector questioning your life choices.

3. Blend the Marshmallow Milkshake

Add the chocolate ice cream, 1 cup of the milk, marshmallow fluff, vanilla extract, and deeply toasted marshmallows to your blender.

Blend until smooth and creamy.

Check the consistency before adding the remaining milk. Add additional milk a little at a time until the shake reaches your favorite thickness.

If you accidentally make it too thin, add another scoop of chocolate ice cream and blend briefly.

4. Garnish and Serve

Pour the milkshake into chilled glasses and top each one with the lightly toasted marshmallows.

Add graham cracker crumbs, chocolate syrup, whipped cream, or whatever else makes your inner 10-year-old happy.

Serve immediately with a straw, a spoon, and absolutely no shame.

Expert Tips for the Best Marshmallow Shake

Start With Less Milk

If you like a thick milkshake, do not add all the milk at once. Begin with about 1 cup, blend, and then add more by the splash until the shake is thick enough to sip but still spoon-worthy.

Toast the Marshmallows in Two Batches

The marshmallows going into the blender can be darker than the ones you use for garnish. Those deeply toasted edges add more caramelized marshmallow flavor, while the second batch stays golden and pretty for serving.

Chill the Glasses

Put your glasses in the freezer while you make the shake. A cold glass helps the milkshake stay frosty longer, particularly on a hot summer day.

Watch the Broiler Constantly

Marshmallows can go from pale to golden to burned surprisingly fast. Keep the oven light on and stay nearby while they toast.

Blend Only Until Smooth

Once everything is incorporated, stop the blender. Excessive blending warms the ice cream and can make your shake thinner.

How to Make a S’mores Milkshake

This toasted marshmallow shake is already about two graham crackers away from becoming a s’mores milkshake.

Drizzle chocolate syrup around the inside of the serving glass before adding the milkshake. Sprinkle graham cracker crumbs on top and finish with a toasted marshmallow and a square of chocolate.

Can You Make a Marshmallow Milkshake Ahead of Time?

The finished milkshake is best made immediately before serving. Once ice cream and milk are blended together, the shake will begin to melt and lose that thick, frosty texture.

You can, however, toast the marshmallows ahead of time. Have your toppings ready, chill your serving glasses, and wait to blend the milkshake until everyone is ready for dessert.

If you do have leftover milkshake, freezing it is a better option than leaving it in the refrigerator until it completely melts. Let the frozen shake soften slightly, then reblend it with a small splash of milk until creamy again.

Troubleshooting Your Marshmallow Milkshake

Why Is My Milkshake Too Thin?

Too much milk is the most common reason. Add another scoop or two of chocolate ice cream and blend just until the mixture thickens.

Why Is My Milkshake Too Thick?

Add milk one or two tablespoons at a time and blend briefly after each addition. Small adjustments make it easier to get exactly the consistency you want.

Why Did My Marshmallows Burn?

Marshmallows brown extremely quickly beneath a broiler. Move the baking sheet farther from the heating element if necessary and watch them continuously.

Why Can I Still See Pieces of Toasted Marshmallow?

The sticky centers can take a little extra blending. Stop the blender, scrape down the sides if necessary, and blend again just until smooth.

Frequently Asked Questions

How do you make a marshmallow milkshake?

Blend chocolate ice cream, milk, marshmallow fluff, vanilla extract, and toasted marshmallows until creamy. Start with less milk for a thick marshmallow shake and add more until you reach your preferred consistency.

Can you put marshmallow fluff in a milkshake?

Yes. Marshmallow fluff blends easily into a milkshake and gives the entire shake a sweet marshmallow flavor rather than limiting the marshmallow flavor to the garnish.

Can I use mini marshmallows instead of jumbo marshmallows?

Yes. Spread mini marshmallows in a single layer and watch them especially closely because their smaller size allows them to toast very quickly.

Can I make toasted marshmallows without a broiler?

Yes. Toast marshmallows with a kitchen torch on a heat-safe surface, over an outdoor fire pit, or carefully over a grill.

What ice cream is best for a chocolate marshmallow milkshake?

Classic chocolate ice cream gives this recipe its traditional chocolate-marshmallow flavor. Dark chocolate, chocolate fudge, Rocky Road, vanilla, and even coffee ice cream can also be used for variations.

Can I turn this into a Rocky Road milkshake?

Absolutely. Substitute Rocky Road ice cream for the chocolate ice cream and finish the shake with chopped peanuts, mini marshmallows, chocolate syrup, and toasted marshmallows.

Is a marshmallow milkshake the same as a marshmallow smoothie?

Not really. This recipe is a true dessert-style milkshake made with ice cream, milk, marshmallow fluff, and toasted marshmallows. A smoothie generally uses fruit, yogurt, juice, or similar ingredients rather than an ice cream base.

Can I make this milkshake dairy-free?

You can substitute dairy-free chocolate ice cream and your favorite creamy non-dairy milk. Check the labels on the marshmallows and marshmallow fluff as well if you are preparing the shake for a specific dietary need.
