Ingredients:

• 1 cup butter, softened
• 1 cup sugar
• 1 cup brown sugar
• 2 eggs
• 2 tsp vanilla extract
• 2 1/2 cups all-purpose flour
• 1 tsp baking soda
• 1/2 tsp salt
• 2 cups chocolate chips

Method:

1. Preheat oven to 350°F.
2. In a large bowl, cream butter and sugars together.
3. Add eggs and vanilla, mixing well.
4. In a separate bowl, combine flour, baking soda, and salt.
5. Gradually add the flour mixture to the butter mixture.
6. Stir in the chocolate chips.
7. Spread the cookie dough in a greased 9x13-inch baking pan.
8. Bake for 20-25 minutes until golden brown.

Directions:

• Ensure the butter is softened to allow for easy creaming.
• Spread the cookie dough evenly in the pan using a spatula.
• Use a toothpick to test for doneness; if it comes out clean, the cookie bars are ready.

Tip: Use a non-stick baking pan to prevent the cookie bars from sticking and make cleanup easier.
