Preheat Your Oven: Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking.
Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, cornstarch, and baking powder. Set aside.
Cream Butter and Cream Cheese: In a large mixing bowl, beat together the unsalted butter and cream cheese until the mixture is smooth and creamy.
Add Wet Ingredients: Add in the egg, milk, and vanilla extract. Mix thoroughly until well combined.
Combine Dry and Wet Mixtures: Gradually add the flour mixture to the wet ingredients, stirring until just combined. Be careful not to over-mix!
Fold in Chocolate Chips: Gently fold in the mini chocolate chips, making sure they are evenly distributed throughout the dough.
Form Cookies: Using a tablespoon, drop rounded dollops of dough onto the prepared baking sheet, leaving space between each cookie.
Bake: Place in the preheated oven and bake for 10-12 minutes or until the edges are lightly golden.
Cool and Enjoy: Allow the cookies to cool on the baking sheet for a few minutes before transferring to a wire rack. Enjoy their gooey goodness!
