Creating Easy Marble Cookies with Chocolate Chip Swirls can be straightforward if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Prepare a baking sheet by lining it with parchment paper.

2. Creaming Butter and Sugars: In a large bowl, use an electric mixer to beat the softened butter, granulated sugar, and brown sugar together until light and fluffy.

3. Add Eggs and Vanilla: Beat in the eggs, one at a time, followed by the vanilla extract, mixing well after each addition.

4. Mix Dry Ingredients: In another bowl, whisk together the all-purpose flour, baking soda, cocoa powder, and salt until well combined.

5. Combine Mixtures: Gradually add the dry mixture to the butter mixture, stirring until just combined. Be careful not to over-mix the dough.

6. Add Chocolate Chips: Fold in the semi-sweet chocolate chips to the dough, ensuring an even distribution.

7. Scoop and Bake: Drop tablespoons of the cookie dough onto the prepared baking sheet, leaving enough space between each cookie for spreading. Bake for 10-12 minutes until edges are lightly golden. Allow cookies to cool on the sheet for 10 minutes before transferring to a wire rack.

These steps will guide you in creating incredible cookies that will become a staple in your baking repertoire!
