Vanilla Melting Moments Sandwich Cookies with Nutella-Cream Cheese Filling

"These buttery cookies are so soft and literally melt in your mouth. They're solid in your hand, but upon biting into one, they softly crumble and melt away into a smooth, buttery haze. The cookies are a great blank canvas for the intensity of the chocolaty, slightly tangy, Nutella-cream cheese filling. The cookies can likely be made with margarine or a vegan buttery spread, thereby keeping them vegan since there's no egg. There's also no baking powder or baking soda in these feathery soft and tender cookies, so chilled dough is mandatory. Optional tweaks include adding peppermint extract or lemon extract/lemon zest to the dough and if going the lemon route, a lemon buttercream would be a great filling. Optionally, using a smear of Nutella, peanut butter, or Cookie Butter/Biscoff rather than making a proper filling is a time-saving tip...."
