What Makes This Recipe So Good
It’s dessert-meets-coffee—without the sugar crash. The marshmallows sweeten and thicken the milk, giving you that café-style latte texture with minimal effort.
You can control the sweetness by adjusting how many marshmallows you melt.
Ultra-customizable. Dairy or oat, espresso or strong brewed coffee, vanilla or cinnamon—this latte plays well with all your favorites. It’s forgiving and still tastes like a cloud.
Quick and fancy-looking. From zero to cozy in under 10 minutes, and it looks like you paid $7 for it. Toasted marshmallows on top?
Your Instagram is already applauding.
Warm, nostalgic flavor. The melted marshmallows bring a gentle caramel note, especially if you give them the tiniest toast under a flame. It’s like campfire vibes… minus the smoke in your hair.
Shopping List – Ingredients
- Espresso or strong brewed coffee – 1–2 shots espresso (about 2 oz) or 1/2 cup strong coffee
- Milk of choice – 3/4 to 1 cup (dairy, oat, or almond work well)
- Mini marshmallows – 1/3 to 1/2 cup (plus extra for topping)
- Vanilla extract – 1/4 teaspoon
- Pinch of salt – enhances flavor, balances sweetness
- Ground cinnamon or nutmeg – optional, a pinch for warmth
- Whipped cream – optional but delightful
- Cocoa powder or chocolate shavings – optional garnish
The Method – Instructions
- Brew your base. Pull 1–2 shots of espresso or brew 1/2 cup strong coffee. Keep it hot.
If using coffee, make it bold so it doesn’t get lost under the marshmallow magic.
- Warm the milk. In a small saucepan over medium-low heat, add the milk. Don’t boil it. You’re aiming for steamy and warm, about 150–160°F if you like numbers.
- Stir in marshmallows. Add 1/3–1/2 cup mini marshmallows to the warm milk.
Whisk until melted and smooth. This should take 1–2 minutes. If it gets too thick, add a splash of milk.
- Flavor boost. Stir in vanilla extract, a tiny pinch of salt, and a pinch of cinnamon or nutmeg if using.
Taste and adjust sweetness by adding a few more marshmallows (no judgement).
- Froth it. Use a milk frother, whisk vigorously, or shake the mixture in a heat-safe jar (careful, it’s hot) for 15–20 seconds to build foam.
- Combine. Pour the espresso or coffee into a large mug. Slowly stream in the marshmallow milk, holding back the foam with a spoon, then spoon the foam on top.
- Finish strong. Top with a few mini marshmallows, whipped cream if you’re feeling extra, and a dusting of cocoa or cinnamon. For a pro move, lightly toast the marshmallows with a kitchen torch.
- Sip immediately. Lattes wait for no one.
The foam will settle and the marshmallows will melt into the cup—aka flavor evolution.
How to Store
Short answer: This is best fresh. Foam and melted marshmallows don’t age like fine wine.
- If you must: Store the marshmallow milk (without foam) in an airtight jar in the fridge up to 2 days. Rewarm gently and re-froth before serving.
- Do not store assembled latte. Coffee flavor dulls and the texture gets sad.
Make fresh coffee when ready to drink.
- Freeze? Not recommended. Thawed milk + marshmallow mix turns grainy, IMO.
Nutritional Perks
- Energy lift with comfort. Espresso brings focus, while the milk and marshmallow offer quick carbs for a cozy boost.
- Protein and calcium (if using dairy). A cup of dairy milk adds roughly 8g protein and a solid calcium hit.
- Customizable sweetness. You control the marshmallow count, so you can keep sugar reasonable while still getting that nostalgic flavor.
- Dairy-free friendly. Use fortified oat or almond milk for a lighter sip with added vitamins.
What Not to Do
- Don’t boil the milk. It scorches, separates, and ruins the smooth latte texture. Gentle heat wins.
- Don’t skip the pinch of salt. It doesn’t make it salty—it makes it balanced.
Chemistry, baby.
- Don’t use weak coffee.-strong> The marshmallow will steamroll it. Go bold or go home.
- Don’t add marshmallows to boiling liquid. They’ll seize and get gummy. Melt them low and slow.
- Don’t over-froth. Big bubbles = airy bath foam.
Aim for microfoam: tiny bubbles, silky feel.
Variations You Can Try
- S’mores Latte: Rim the mug with melted chocolate and crushed graham crackers. Add a square of chocolate under the foam. Try not to grin.
- Salted Caramel Marshmallow: Drizzle caramel sauce in the mug, add a bigger pinch of flaky salt on top.
Sweet-salty perfection.
- Peppermint Twist: Add 1–2 drops peppermint extract to the milk and garnish with crushed candy cane. Holiday in a cup.
- Mocha Cloud: Whisk 1 teaspoon cocoa powder into the milk before melting marshmallows. Chocolate + marshmallow = obvious win.
- Maple Vanilla: Swap some marshmallows for 1–2 teaspoons pure maple syrup and keep the vanilla.
Cozy breakfast vibes.
- Iced Version: Make the marshmallow milk, chill it, then pour over ice with cold brew. Top with cold foam and a few mini mallows.
- Protein Boost: Stir in unflavored or vanilla protein powder to the warm milk before frothing. Whisk thoroughly to avoid clumps.
FAQ
Can I make this without espresso?
Yes.
Use very strong brewed coffee or concentrated instant coffee. Aim for bold flavor so it stands up to the marshmallow sweetness.
Do I need a frother?
Nope. A whisk or a tightly sealed heat-safe jar works.
Frothers just make it easier to get that silky microfoam texture.
What’s the best milk for frothing?
Whole milk froths beautifully and tastes luxe. For non-dairy, barista-style oat milk is the most reliable, with almond and soy close behind.
Can I use large marshmallows?
Yes, just chop or tear them into smaller pieces so they melt faster and more evenly. Mini marshmallows are simply less drama.
How do I toast the marshmallows safely?
Use a kitchen torch to lightly brown marshmallows on top of the latte or on a parchment-lined tray before placing them on the foam.
No torch? Pop them under a broiler for 15–30 seconds—watch closely.
Is there a lower-sugar option?
Use fewer marshmallows and add vanilla plus a pinch of cinnamon for perceived sweetness. You can also use sugar-free marshmallows if you like, though texture may vary.
Can I make a big batch?
You can batch the marshmallow milk in a saucepan for 2–4 servings, then froth per cup.
Brew fresh espresso or coffee for each mug for best flavor.
