Preheat oven to 350°F. Line a cookie sheet with parchment paper and spray with non-stick spray.

In a stand mixer combine butter and both sugars, mix on medium speed using a paddle attachment until well blended.

Add the egg and mix until the egg is incorporated thoroughly.

Add your whole milk, mix on low speed then turn to high briefly, mixing just into milk incorporates fully.

Add your flour, salt and baking soda to the mixer, and mix on low until combined. Turn mixer off and remove bowl.

Add vanilla and chocolate chips, and mix those by hand with a wooden spoon.

Spread on a parchment lined round pizza pan.

It is helpful to start in middle and push outwards. Smooth as best you can with an offset spatula, or use the back of a metal spoon sprayed with non-stick spray.

Place in oven and bake for 12 to 15 minutes.

Remove the pizza pan from oven and allow to cool completely.

Scoop Nutella into a medium sized bowl. Set aside.

In a small saucepan warm your heavy cream until it just starts to boil.

Pour it over the bowl of Nutella you set aside, and whisk until smooth. It takes some time so just keep whisking until it starts to thicken. It takes a few minutes to get it smooth and thick. If it's not thick enough for you add a little more Nutella, 1 tablespoon at a time until you reach the desired thickness you like.

Melt the white chocolate in the microwave until it's smooth, 2 to 3 ounces should take 1 to 1 1/2 minutes in the microwave. My microwave is pretty powerful and everyone's varies so much. So I suggest cooking for 30 seconds, then start checking it every 15 seconds. Stir with a spoon to check how it's doing every 15 seconds.

Once it's melted drizzle it in random patterns over the cookie pizza with Nutella ganache. Allow chocolate to cool.

Toss on once the chocolate cools slightly so you don't melt the candies.

Cut with a pizza cutter for even slices. You can also use a pizza rocker. We love ours.

Serve with a big old Cookie Pizza loving smile.
