FAQs
Can I use instant coffee instead of espresso?
Yes, mix 2 teaspoons of instant coffee with 2 ounces of hot water to substitute for espresso.
What kind of peanut butter works best?
Creamy peanut butter works best for smooth blending, but crunchy peanut butter can add texture if preferred.
Is marshmallow fluff the same as melted marshmallows?
Not exactly. Marshmallow fluff is spreadable and blends easily. Melted marshmallows can work in a pinch but may be harder to dissolve.

How sweet is this latte?

Can I make this vegan?
Yes, use dairy-free milk, plant-based cream, and a vegan marshmallow fluff alternative.
Can I make it hot instead of iced?
Yes, skip the ice and use steamed milk instead of cold milk. Great for cooler days.
What if I don’t have a frother?
You can whisk vigorously by hand or shake ingredients in a tightly sealed jar.
How do I make nutter butter crumbs?
Crush nutter butter cookies in a zip-top bag with a rolling pin or use a food processor.
Can I use chocolate syrup for extra sweetness?
Yes, swirl chocolate syrup inside the glass or drizzle it on top for added flavor.
