Best EVER Chocolate Chip Cookies

adapted from: Anna Olson

3/4 c. unsalted butter, softened

3/4 c. brown sugar

1/4 c. sugar

1 egg

2 tsp. vanilla extract

2 c. all-purpose flour

2 tsp. cornstarch

1 tsp. baking soda

1/2 tsp. salt

chocolate chips, as many as you like

Cream together butter, brown sugar and sugar until light and fluffy.  Add the egg and vanilla and beat to combine.  Combine the flour, cornstarch, baking soda and salt and add to wet ingredients.  Mix to combine and stir in the chocolate chips.  Chill dough for at least 30 minutes.  Preheat oven to 350 degrees.  Use a small cookie scoop and drop dough onto a greased cookie sheet.  Bake 8-10 minutes or until barely golden around the edges.  The key is to NOT overbake.  

If you want crispy cookies, omit the cornstarch and replace the baking soda with baking powder.

**Jenn's Notes Update:  I LOVE these cookies and I make them all of the time.  If the dough looks a little crumbly while mixing, don't worry, it will come together.  I get between 27 and 30 cookies and I bake them for 10 minutes (NO LONGER).  They will look underdone, but they set up perfectly.
