Step 1: Preheat the Oven

1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.

Step 2: Cream the Butter and Sugars

1. In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy (about 2-3 minutes).
2. Beat in the egg and vanilla extract until well combined.

Step 3: Combine Dry Ingredients

1. In a separate bowl, whisk together the flour, baking soda, and salt.
2. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Step 4: Add Chocolate and Cranberries

1. Gently fold in the white chocolate chips and dried cranberries until evenly distributed throughout the dough.

Step 5: Scoop and Bake

1. Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
2. Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden and the centers are set but still soft.

Step 6: Cool and Serve

1. Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
2. Serve warm or store in an airtight container for later enjoyment!
