Add ice cream, chocolate syrup, and maca powder and blend on low until creamy and smooth. If it has trouble blending, add a bit of almond or coconut milk (I didn't find it necessary and prefer my malts thick).
Taste and adjust flavor as needed, adding more chocolate syrup for intense chocolate flavor or maca for a more "malty" flavor.
Enjoy as is or top with coconut whipped cream and more chocolate syrup (optional). Best when fresh.
*If you don't care to make chocolate syrup, either use a store-bought vegan-friendly brand, or try subbing cocoa or cacao powder. *Maca powder adds the malty flavor in this dessert. If you can't get your hands on it, just leave it out! *Nutrition information is a rough estimate calculated without additional chocolate syrup or coconut whipped cream.
