Preheat your oven to a cosy 350°F (175°C), and prepare those baking sheets with parchment paper.
In a big bowl, beat the butter and cream cheese with your trusty mixer until they’re creamy and friendly.
Add the sugar and beat it like nobody’s watching until the mix is fluffy like a cloud.
Toss in the egg and vanilla extract and give it more mix-love.
Whisk flour, baking powder, and salt; let them get to know each other.
Gradually introduce the dry friends to the cream cheese party, mixing until everyone’s having fun.
Chill the dough in the fridge for 30 minutes—just enough time to dream about cookies.
Mix 1/4 cup sugar and cinnamon in a small bowl—time for a sugary cinnamon ball!
Roll a tablespoon of dough into a ball and give it a cinnamon-sugar coat—like a cookie in a snazzy sweater.
Place those balls on the prepared baking sheets and flatten them.
Bake for 10-12 minutes; wait until the cookies’ edges are just a shade of golden sunshine.
Let the cookies cool on the sheet, then transfer to a wire rack to chill out thoroughly.
