Preheat your oven to 350°F (175°C) to ensure even baking.
In a large mixing bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
In another bowl, cream together the cold butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes.
Add the eggs and vanilla extract to the butter mixture, mixing until well combined.
Gradually add the dry mixture to the wet ingredients, mixing on low speed until just combined to keep cookies tender.
Gently fold in the standard and mini chocolate chips with a spatula until evenly distributed.
Scoop heaping tablespoons of dough onto lined baking sheets, leaving space for spreading.
Bake for 10-12 minutes until edges are golden brown and centers are just set. They will firm up as they cool.
Let cool on baking sheets for about 5 minutes before transferring to wire racks to cool completely.
