Prep the Oven:
🌡️ Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper.

Cream Butter & Sugars:
In a large bowl, beat the softened butter, granulated sugar, and brown sugar until light and fluffy (about 3 minutes).

Add Wet Ingredients:
Beat in the eggs one at a time, then stir in the vanilla extract.

Mix Dry Ingredients:
In a separate bowl, whisk together the flour, baking soda, baking powder, cornstarch, and salt.

Combine Wet & Dry:
Gradually add the dry ingredients to the wet mixture. Stir until just combined—don’t overmix. Fold in the chocolate chips.

Shape the Cookies:
🍪 Use a large cookie scoop or 1/4 cup of dough per cookie. Roll into balls and slightly flatten them for that signature Crumbl look.

Bake:
Bake for 10–12 minutes, or until the edges are lightly golden. The centers should look slightly underbaked for a soft texture.

Cool:
Allow the cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Optional Frosting:
For frosted cookies, beat together the frosting ingredients until smooth and fluffy. Once the cookies are cool, frost and enjoy!
