Mexican Chocolate Cookies {Cottage Cheese Cookies}

Preheat oven to 375 degrees. Line a baking sheet with silicone baking mats or parchment paper; set aside. In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, salt, and cinnamon; set aside. In the bowl of a stand mixer fitted with a paddle attachment, beat the cottage cheese for about a minute. Stir in the butter and sugars on low for 30 seconds; turn up speed to medium and beat for 1 minute. Reduce speed to low and add egg and vanilla, beating for 1 minute. Gradually add the flour mixture to the butter mixture, and stir until incorporated. Using a small cookie scoop, drop dough balls onto prepared baking sheets about 2 inches apart. Gently push 1 chocolate disk into each dough ball. Bake on center rack for 10 minutes, or until edges of cookies are set. Let cookies cool on sheet for 2-3 minutes. Transfer to a wire rack to cool. While cookies are warm (not hot), sift some powdered sugar over them.
