How to Make Fluffy Latte with Marshmallow and Nutter Butter Crumbs Recipe
Step 1: Prepare Your Glass
Begin by spreading 3 tablespoons of marshmallow fluff around the inside of your glass using the back of a spoon. This little trick not only ensures each sip has that luscious sweetness but also creates an irresistible sticky coating that’s pure delight. Then fill the glass about three-quarters full with ice to keep your latte perfectly chilled.
Step 2: Mix the Espresso Base
Into a separate glass or small jug, combine 2 tablespoons of creamy peanut butter, 2 teaspoons of light brown sugar, and â…› teaspoon of salt. Brew 2 ounces of fresh, hot espresso right over this mixture. Use a hand frother or whisk vigorously until the peanut butter fully dissolves and the sugar is perfectly blended, forming a smooth and rich coffee base.
Step 3: Combine and Chill
Pour your freshly frothed espresso mixture over the ice in your marshmallow-coated glass. Follow this by adding 1 cup of your preferred milk (dairy or plant-based works wonderfully). This combination will begin to meld those deep coffee flavors with creamy sweetness for a flawless latte base.
Step 4: Whip the Fluffy Foam
In a clean glass or small bowl, mix 3 tablespoons heavy cream, 2 tablespoons milk, 1 tablespoon marshmallow fluff, and a pinch of salt. Use your hand frother to whip this mixture until it becomes thick, light, and cloud-like—this is that signature fluffy foam that makes this recipe so special and unbelievably indulgent.
Step 5: Top and Garnish
Gently spoon the velvety foam on top of your iced latte, creating a pillowy layer that’s both visually stunning and delicious. Finally, sprinkle 2 teaspoons of Nutter Butter crumbs over the foam for that much-needed crunch and nostalgic peanut buttery flavor that ties the whole drink together in the most delightful way.
How to Serve Fluffy Latte with Marshmallow and Nutter Butter Crumbs Recipe
Garnishes
To really elevate your Fluffy Latte with Marshmallow and Nutter Butter Crumbs Recipe, try a light dusting of cocoa powder or a drizzle of peanut butter sauce alongside the Nutter Butter crumbs. A mini marshmallow or two perched on the foam also adds a charming, whimsical touch that will make both you and your guests smile.
Side Dishes
This indulgent latte pairs exceptionally well with buttery pastries, such as croissants or nutty biscotti, which complement the nutty peanut butter notes in the drink. If you want to keep things light, a fresh fruit salad with berries provides a refreshing contrast that balances the creamy richness.
Creative Ways to Present
Present this latte in a clear glass mug to showcase the beautiful layers of marshmallow fluff, espresso, and milk. Consider serving with a cute spoon or stirrer that guests can use to mix up the marshmallow fluff coating inside the glass as they sip. For a festive touch, top with edible gold dust or a sprinkle of crushed Nutter Butter crumbs on the rim.
Make Ahead and Storage
Storing Leftovers
Although this Fluffy Latte with Marshmallow and Nutter Butter Crumbs Recipe is best enjoyed fresh, you can store prepared espresso and milk mixture in the fridge for up to 24 hours. Keep the fluffy cream foam separate and whip fresh before serving to maintain its light texture.
Freezing
Freezing this latte is not recommended, especially because the delicate marshmallow foam and ice would be compromised. For best flavor and texture, make each serving fresh.
Reheating
If you find yourself with leftover latte mixture (without ice or foam), reheat gently on the stove or in the microwave until warm but not boiling. Add freshly whipped marshmallow foam and ice just before serving to recreate that perfect texture.
FAQs
Can I use regular marshmallows instead of marshmallow fluff?
Marshmallow fluff has a lighter, spreadable consistency ideal for coating the glass and whipping into the foam. While you can melt regular marshmallows and try, the texture won’t be quite as smooth or fluffy, so marshmallow fluff is definitely the preferred choice.
Is this recipe suitable for non-dairy milk?
Absolutely! Plant-based milks like almond, oat, or cashew milk work wonderfully here, each lending a subtle flavor twist while keeping the latte creamy and delicious.
Can I make this latte hot instead of iced?
You can! Just skip the ice and prepare the marshmallow fluff coating on the inside of a warmed glass or mug. Pour the hot espresso mixture and warm milk over it, then top with freshly whipped marshmallow cream as usual.
Where can I find Nutter Butter crumbs?
If you can’t find pre-made Nutter Butter crumbs, simply crush Nutter Butter cookies in a sealed bag using a rolling pin or heavy pan until finely crushed. They add that perfect peanut buttery crunch.
Can I double or triple this recipe for more servings?
Yes! The Fluffy Latte with Marshmallow and Nutter Butter Crumbs Recipe scales beautifully. Just multiply ingredients accordingly and whip the foam fresh for each batch to keep it fluffy and light.
