Preheat oven to 350°F.

Line 3 baking sheets with parchment paper and set aside.

Sift together the flour and baking soda in a small bowl and set aside.

In a large mixing bowl, combine the butter, granulated sugar, and light brown sugar; beat on medium speed until light and fluffy.

Add the salt, vanilla extract, and eggs; continue to beat on low until thoroughly combined.

Slowly add the flour mixture and mix until just combined.

Stir in the semisweet chocolate chips.

Drop by rounded tablespoon onto prepared baking sheets, spacing them 2 inches apart.

Bake for 8 to 10 minutes, or until cookies are golden brown around the edges.

Remove from oven and let cool for 2 minutes on the baking sheet; transfer to a wire rack and let cool completely.

While cookies cool, prepare the filling by combining cream cheese and powdered sugar in a bowl; beat until creamy.

Add melted white chocolate chips and Nutella; mix until fully combined.

Refrigerate filling for 10 minutes before use.

Spread filling on the flat side of half the cookies and top with remaining cookies.

Refrigerate sandwiches for 20 minutes to allow filling to set slightly.

Serve at room temperature.
