Best Chocolate Chip Cookies EVER!!

I have never in my life been able to make a really GOOD Chocolate Chip Cookie, you know the kind that stay nice and soft and chewy...Until yesterday! I had a few friends over for some treats in celebration of finishing an 11 day diet, I know I know kind of contradicting doing a diet then finishing with junk food. But lets just say that these cookies did not disappoint and were so worth the 11 days!!

Ingredients

2 sticks unsalted butter
2 1/4 cups bread flour
1 teaspoon kosher salt
1 teaspoon baking soda
1/4 cup sugar
1 1/4 cups brown sugar
1 egg
1 egg yolk
2 tablespoons milk
1 1/2 teaspoons vanilla extract
2 cups semisweet chocolate chips

Directions

Heat oven to 375 degrees F.

Melt the butter in a heavy-bottom medium saucepan over low heat. Sift together the flour, salt, and baking soda and set aside.

Pour the melted butter in the mixer's work bowl. Add the sugar and brown sugar. Cream the butter and sugars on medium speed. Add the egg, yolk, 2 tablespoons milk and vanilla extract and mix until well combined. Slowly incorporate the flour mixture until thoroughly combined. Stir in the chocolate chips.

Chill the dough for 24 hours. Bake for 14 minutes or until golden brown (mine were finished in 12 minutes), checking the cookies after 5 minutes. Rotate the baking sheet for even browning. Cool completely and store in an airtight container.

(I only baked half of the dough because I didn't want to completely undo my progress from the diet)

*TIP* When storing chocolate chip cookies, keep a slice of bread in the air tight container. It will keep the cookies moist and chewy!
