Preheat: Preheat oven to 350°F and line sheet pans with parchment paper and set aside.
Mix wet ingredients: In a large bowl, add the softened butter and sugars and beat with a mixer or whisk for 2-3 minutes, until the mixture looks fluffy and creamy and is no longer gritty. Scrape down the sides of the bowl with a rubber spatula. Add the egg and vanilla and beat for another 1-2 minutes. The mixture will look fluffy, smooth, and glossy.
1/2 cup salted butter, 1/4 cup granulated sugar, 3/4 cup light brown sugar, 1 large egg, 2 teaspoons vanilla bean paste
Add dry ingredients: Add flour, cinnamon, baking powder, and baking soda and mix just until combined. Mix in the chocolate and cinnamon chips briefly (don't overmix the dough!)
1 3/4 cup all purpose flour, 1 1/2 teaspoons ground cinnamon, 1 teaspoon baking soda, 1/2 teaspoon baking powder, 1/2 cup semi-sweet chocolate chips, 1/2 cup cinnamon chips
Bake: Use a small cookie scoop to scoop the cookie dough onto the prepared baking sheets. Bake for 9-12 minutes. Cooking time will vary based on your oven, so bake the cookies until they are golden brown on the edges but still soft in the middle (they'll continue to cook as they cool on the pan).
