Nothing can compare to a delicious chocolate chip cookie. But these cookies have a special treat inside -- white chocolate! Crispy on the edges and soft in the middle these chocolate chip cookies have both chopped dark chocolate, white chocolate and walnuts for an irresistible treat.
Preheat to 350°F. Place rack in the middle of the oven. Grease or place parchment on a baking sheet (These steps can wait if chilling dough overnight).
Combine and mix dry ingredients in a mixing bowl: flour, baking soda, salt. Set aside.
In a mixer fitted with a paddle attachment cream the softened butter, white and light brown sugars, and vanilla together. Then add the melted butter and egg. Mix until nicely combined - 2 minutes.
With the mixer on slowly add the dry ingredients to the bowl with the wet and mix together until flour is incorporated. Then increase to medium speed for 1 minute.
Finally, add the white and dark chocolate chips, nuts (optional) and mix until evenly combined. Chill overnight (24 hours). Chilling is not required but will intensify the flavor. Remove from the fridge and place on a baking sheet either greased or fitted with parchment or a Silpat mat.
Using a 1/8 cup measuring cup, mini ice-cream scoop or spoon drop cookies onto baking pan about 3 inches apart. Bake for 8 minutes or when cookies are lightly browned on the edges and risen in the middle.
