To make the vanilla sandwich cookies and the Nutella filling, you’ll need: Simply beat the butter, then add flour, cornstarch, confectioners’ sugar, vanilla, and mix until the dough comes together. My dough started out very dry and crumbly, but after a couple minutes, it came together perfectly, to the point it was quite soft.
What’s in Melting Moments Cookies? To make the vanilla sandwich cookies and the Nutella filling, you’ll need: Simply beat the butter, then add flour, cornstarch, confectioners’ sugar, vanilla, and mix until the dough comes together.
Vanilla-Cream Filling: Put the butter and shortening in a mixing bowl and, at low speed, gradually beat in the confectioners' sugar and vanilla, until blended. Turn the mixer up to high and beat for 2 or 3 minutes more, until fluffy. With a pastry bag fitted with a 1/2-inch tip, pipe teaspoon size blobs of filling onto the tops of half the cookies.
I made the filling by using 3/4 cup Nutella, 1/4 cup light cream cheese, confectioners’ sugar, vanilla, and a splash of cream. You’ll need to play with the cream ratio to get your frosting to combine. I find that not all jars of Nutella are the same.
