Preheat oven to 350°F and line 2 baking sheets with parchment paper.
In a medium bowl, combine flour, baking soda, and salt. Set aside.
In the bowl of a standing mixer with the paddle attachment or a handheld mixer, combine butter and sugars, mixing until light and fluffy (1-2 minutes).
Add in the egg and vanilla extract, and beat until just combined (do not over-mix!).
Mix in the dry ingredients until a dough forms. Stir in the chocolate chips and mix until just combined.
Use a medium cookie scoop or spoon to make 1.5 tablespoon sized balls and place them on the baking sheet around 3-4 inches apart.
Gently press an Oreo cookie into each ball of dough, then cover with another 1-1.5 Tablespoons of dough to seal the edges. Add a few more chocolate chips on top of the dough if desired.
Bake the cookies (one sheet at a time for even baking) for 8-11 minutes. Remove them from the oven when the edges look set. They should look a little under-baked in the middle! Remove from the oven and leave them on the baking sheet for 5 minutes, then transfer to a cooling rack to cool completely. Enjoy!

Notes
Measuring Flour: Properly measure your flour using either a kitchen scale or by fluffing it up in the bag with a fork, then using a spoon to scoop the flour into the measuring cup and then use the back of a butterknife to level it off (the is the scoop and level method)Chocolate Chips: You can use any kind of chocolate chips here. I like to use semisweet. You can also use a chopped up chocolate bar or even white chocolate chips.Oreos: Feel free to use any kind of Oreo flavors if you want to mix it up!Storage and Freezing:Store the cookies in an airtight container or ziploc bag at room temperature for 5-6 days.The baked cookies can be frozen in a freezer bag for up to 2 months. Thaw at room temperature when you're ready to eat them.
