Step 1

Preheat the oven to 350 degrees Fahrenheit.

Step 2

Stir together the flour, pudding mix, baking soda and salt. Set aside.

Step 3

Beat the butter and both sugars together in a large bowl with a stand up mixer or hand held mixer until the mixture is creamy and light.

Step 4

Add in the eggs and vanilla extract.  Mix until all the ingredients are combined.

Step 5

Gradually add the flour mixture into the egg mixture until just combined.  Be careful not to over mix. Add in green food coloring until the dough is a deeper green color.

Step 6

Gently stir in the white chocolate chips and crushed pistachios into the cookie batter by hand.

Step 7

Drop the cookie dough by rounded tablespoons onto a baking sheet.  Bake for 10-12 minutes until the cookies are slightly golden brown around the edges.

Step 8

Remove the cookies from the oven.  Press a few additional white chocolate chips into the tops of the cookies while they are warm.

Step 9

Let them sit on the baking sheets for 5 minutes and then transfer the cookies to a wire rack to cool completely.
