Cream together the butter and sugars in a stand mixer until smooth, about 2-3 minutes. Add the eggs and vanilla, making sure to scrape down the sides of the mixing bowl. Add the flour, salt, baking soda and baking powder and mix on low until everything is incorporated. Stir in the dark chocolate morsels by hand. Cover the dough with plastic wrap and refrigerate for at least 2 hours.

Preheat your oven to 350 degrees

Scoop out 3 tablespoons worth of dough and roll the dough into a ball. Place the cookies onto a parchment lined baking sheet, about 12 per sheet and add a few dark chocolate morsels on the tops of the cookie (these will allow the dark chocolate morsels to be front and center once baked), and bake for 12-13 minutes until the edges are just slightly golden brown and the center is still a bit soft.

Remove the baking sheet from the oven and let the cookies rest for about 10 minutes before transferring them to a cooling rack. Repeat this process for the remaining dough.

Stack 1 cookie on a small cake plate and add a dollop of frosting on top. Repeat so there are 3 layers to each cake and finish with a dollop of icing. Add a dark chocolate morsels on top and serve as needed. (I like to eat these with a knife and fork!!)
