INGREDIENTS
1/2 cup (1 stick) unsalted butter, softened
1 pkg cream cheese, softened
3/4 cup light brown sugar, packed
1/4 cup granulated sugar
1 large egg
2 teaspoons vanilla extract
2 1/4 cups all-purpose flour
2 teaspoons cornstarch
1 teaspoon baking soda
1 tsp Espresso
1/4 teaspoon salt, optional and to taste
2 1/4 cups semi-sweet chocolate chips or chunks
(I use 1 1/4 c chunks and 1 c semi sweet chips and white chips mixed)
INGREDIENTS
Combine the butter, cream cheese (measure it by smooshing it into a 1/4-cup measure), sugars, egg, vanilla, and beat on medium-high speed until well-creamed, light and fluffy, about 5 minutes (or use an electric hand mixer and beat for at least 7 minutes).
Stop, scrape down the sides of the bowl, and add the flour, cornstarch, baking soda, optional salt, and mix until just combined, about 1 minute.
Add chocolate chips and chunks, and beat momentarily to incorporate, or fold in by hand.
Cover with plasticwrap, and refrigerate for at least 2 hours, or up to 5 days, before baking. Do not bake with warm dough because cookies will spread and bake thinner and flatter.
Preheat oven to 350F, line a baking sheet with a Silpat Non-Stick Baking Mat or spray with cooking spray and place mounds on baking sheet, spaced at least 2 inches apart (I bake 5 to 8 cookies per sheet).
Bake for 8 to 9 minutes, or until edges have set and tops are just beginning to set, even if slightly undercooked, pale and glossy in the center. Do not bake longer than 10 minutes as cookies will firm up as they cool.
