Ultimate Oreo-Stuffed Chocolate Chip Cookies

Preheat the oven to 350 degrees F (175 degrees C). Line two baking sheets with aluminum foil.

Beat butter, brown sugar, and white sugar in a large bowl with an electric mixer on medium speed for at least 3 minutes. Scrape down the sides of the bowl and add eggs, vanilla, and cinnamon; beat on low speed until incorporated and fluffy, about 1 minute.

Scrape down the sides of the bowl again. Mix in 1 cup of flour and baking powder until incorporated. Fold in 1 cup of flour. Fold in remaining 1 cup flour with chocolate chips until nicely incorporated.

To form cookies, press 1 tablespoon batter between your hands and flatten slightly. Put an Oreo on top and add another tablespoon dough on top of the Oreo. Shape dough softly around the cookie to sandwich it. Place on a prepared baking sheet. Repeat to form remaining cookies, spacing them 1 inch apart on the sheets.

Bake in the preheated oven until edges are golden, about 15 minutes. Cool on the baking sheets briefly before removing to a wire rack to cool completely, 20 to 30 minutes.
