Step 1: Preheat your oven to 350°F (175°C). This temperature ensures that the cookies bake evenly without burning. Line a baking sheet with parchment paper. Parchment paper prevents the cookies from sticking to the pan and makes cleanup a breeze. Using a baking sheet is highly recommended, as greasing the pan directly can lead to uneven baking and potential sticking.
Step 2: In a medium-sized bowl, whisk together the all-purpose flour, baking powder, and salt. Whisking ensures that these dry ingredients are evenly distributed, which is essential for consistent baking. This step also helps to incorporate air into the flour, resulting in a lighter cookie. Set this bowl aside.
Step 3: In a large bowl, cream together the softened butter, granulated sugar, and brown sugar using an electric mixer. Beat on medium speed until the mixture is light and fluffy, about 3-5 minutes. This step is crucial for creating a tender cookie. Creaming the butter and sugar incorporates air, which contributes to the cookie's soft texture. Ensure that the butter is properly softened to avoid lumps in the dough.
Step 4: Add the egg and vanilla extract to the creamed mixture and mix until well combined. Then, blend in the softened cream cheese until the mixture is smooth and creamy. The cream cheese should be at room temperature to avoid clumping. Be sure to scrape down the sides of the bowl to ensure that all ingredients are fully incorporated.
Step 5: Gradually add the dry ingredients (flour mixture) to the wet mixture, mixing on low speed until just combined. Be careful not to overmix, as this can result in tough cookies. Mix only until the flour is just incorporated; a few streaks of flour are acceptable. Overmixing develops the gluten in the flour, which can lead to a denser, chewier cookie.
Step 6: Use a cookie scoop or a spoon to drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart. This allows the cookies room to spread as they bake. If you don't have a cookie scoop, you can use a tablespoon to portion out the dough.
Step 7: Bake for 12-15 minutes, or until the edges are lightly golden brown. The cookies should be slightly soft in the center when you remove them from the oven. They will continue to set as they cool. Avoid overbaking, as this can result in dry cookies.
Step 8: While the cookies are still warm, prepare the cinnamon sugar coating. In a small bowl, mix together the 1/4 cup of granulated sugar and 1 tablespoon of ground cinnamon. Ensure that the cinnamon is evenly distributed throughout the sugar.
Step 9: While the cookies are still warm, gently roll each cookie in the cinnamon sugar mixture to coat evenly. The warmth of the cookies will help the sugar to adhere better. Ensure that each cookie is thoroughly coated for the best flavor and texture. Place the coated cookies on a wire rack to cool completely.
