Step 1

Preheat the oven to 325 degrees Fahrenheit.

Step 2

Combine the butter and brown sugar in a large bowl. Mix until they are creamy, well-blended, and fluffy. Then, add the egg and vanilla; mix thoroughly.

Step 3

Using a separate bowl, combine the flour, baking soda, and salt. Then, add this mixture into the first bowl with the butter and brown sugar mixture.

Step 4

Add the remaining ingredients and stir until everything is blended.

Step 5

Grease the cookie sheets with butter or use parchment paper. Then, spoon the dough onto the cookie sheets in tablespoon-sized balls. Leave approximately an inch between each ball of dough.

Step 6

Bake in the oven at 325 degrees Fahrenheit for approximately 8 to 10 minutes or until the cookies are golden-brown.

Step 7

Remove them from the oven and allow the cookies to cool before storing them in an air-tight container. For best results, serve them after a couple of days have passed.
