Preheat your oven to 350°F (175°C).
In a mixing bowl, cream together the butter, sugar, and brown sugar until light and fluffy.
Add the vanilla extract and eggs, one at a time, beating well after each addition.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add to the wet ingredients, mixing until just combined.
Spread the cookie dough onto a baking sheet, forming a large circle about ¼ inch thick.
Bake for 12-15 minutes, or until the edges are golden brown. Let it cool completely.
Once cooled, spread Nutella evenly over the cookie base.
Top with your favorite toppings like strawberries, bananas, and nuts. Slice and serve.
