In a large bowl, add the slightly melted butter, sugar, and brown sugar. Mix until well combined. Add the eggs, vanilla, and heavy whipping cream, then whip for about 2 minutes until creamy.
Add the flour, baking soda, and salt. Mix halfway, then add the roughly chopped chocolate chips.
Continue mixing until everything is fully incorporated and there is no flour remaining around the sides of the bowl.
Preheat the oven to 350°F. Scoop the cookie dough onto a parchment-lined baking sheet or silicone baking mat, leaving plenty of space between each cookie.
Bake for 12–15 minutes. About halfway through baking, gently tap the baking sheet on the counter to help the cookies spread and flatten.
Remove from the oven and let the cookies rest on the baking sheet for 15–20 minutes before removing them.
Enjoy! These cookies are thin, delicious, buttery, and loaded with chocolate—just like mine!
