Creating Christmas Kitchen Sink Cookies is simple and fun. Follow these steps to bake your holiday treat:

1. Preheat your oven: Set your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking soda, and salt. Set aside.
3. Cream Butter and Sugars: In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Mix in the eggs one at a time, followed by the vanilla extract, until well incorporated.
5. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients and mix until just combined.
6. Fold in Add-Ins: Gently fold in the chocolate chips, nuts, dried fruit, oatmeal, and coconut flakes, if using.
7. Scoop the Dough: Using a cookie scoop or a tablespoon, drop mounds of dough onto the prepared baking sheet, leaving space between each cookie.
8. Bake: Place the baking sheet in the preheated oven and bake for 10-12 minutes or until the edges are lightly golden.
9. Cool: Remove from the oven and let the cookies cool on the baking sheet for about 10 minutes before transferring them to a wire rack to cool completely.

With these straightforward steps, you’ll create a batch of Christmas Kitchen Sink Cookies that everyone will love!
