Creating a delicious Cookie Cake is straightforward. Just follow these simple steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease a 12-inch round cake pan or line it with parchment paper.
2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking soda, and salt until well combined.
3. Cream Butter and Sugars: In a large mixing bowl, beat the softened butter with granulated sugar and brown sugar until light and fluffy.
4. Add Eggs and Vanilla: Mix in the eggs one at a time, followed by the vanilla extract, ensuring everything is well blended.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined.
6. Fold in Chocolate Chips: Gently fold in the chocolate chips or any other mix-ins you desire.
7. Transfer to Pan: Pour the batter into the prepared cake pan, spreading it evenly.
8. Bake: Place in the preheated oven and bake for 25-30 minutes or until the edges are golden and a toothpick inserted in the center comes out clean.
9. Cool: Once baked, allow the cookie cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
10. Frost (Optional): Once cooled, you can frost the top with your favorite icing or serve as is.

These steps will ensure you create a delicious and satisfying Cookie Cake that everyone will love.
