In the bowl of a stand mixer, or using a hand beater beat butter and both sugars on med-high speed, till light and fluffy. This should take about 1-2 minutes.
½ Cup Butter, ½ Cup Light Brown Sugar, ¼ Cup Granulated Sugar
Now add softened cream cheese and continue to beat till the mixture appears pale and fluffy. About 2 minutes. Next add in egg and beat again till it gets combined. Add vanilla and espresso powder and give it a quick whirl too.
2 oz Cream Cheese, 1 large Egg, 1 teaspoon Instant Espresso Powder, 2 teaspoon Pure Vanilla Extract
Now sift all the dry ingredients (Flour, cornstarch, cocoa, baking soda and salt) over wet. And slowly mix them all in to form dough. Add in chocolate chips. Chill the dough in refrigerator for a minimum of 30 minutes or up to 3-4 hours in the fridge.
1 ¾ Cups All Purpose Flour, 2 teaspoon Cornstarch, ½ Cup Unsweetened Cocoa, 1 teaspoon Baking Soda, ¼ teaspoon Salt, 12 oz Milk Chocolate Chips
When ready to bake, preheat oven to 350 deg F and line 2 baking sheets with silicone mat or parchment paper. Drop about 2 Tablespoons mounds of cookie dough on sheets and place them around 2 inches apart.
Bake for 10-11 minutes. When done, the cookies will appear just set on corners and puffy in the middle. Allow to cool for 4-5 minutes on baking tray and then transfer to wire rack to complete cooling.
