Preheat the oven to 350°F and line a baking sheet with parchment paper.

In a mixing bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy.

Add egg, corn syrup, molasses, and vanilla extract. Mix until well combined.

Incorporate flour, salt, and baking soda. Continue mixing until a sticky dough forms.

Stir in mini chocolate chips evenly throughout the dough.

Use a small scoop, spoon, or clean hands to portion the dough into 1 tbsp balls. Arrange them on the prepared sheet.

Bake at 350°F for 7-9 minutes until the edges turn golden brown.

Let the cookies cool on the pan before transferring to a wire rack.

For the soft edges characteristic of Costco cookies, store them in an airtight container overnight. The edges will soften as they sit.
