Peanut Butter Chocolate Chip Oatmeal Cookies

I found this recipe online a few years ago (I forgot where), and have modified it a bit. I increased the chocolate chips from 1 cup to 1 1/4 cup, and added 1/2 cup of chopped nuts.

Ingredients:
3/4 cup butter
1/2 cup white sugar
1 cup packed brown sugar
2 eggs
1/3 cup creamy peanut butter (if you use chunky, don't use the nuts)
1/4 cup water
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour
1/2 teaspoon baking soda
2 cups rolled oats
1 1/4 cup semisweet chocolate chips/chocolate chunks (more or less to taste)
1/2 cup chopped nuts (optional)

Directions:
1. Preheat oven to 350 degrees F (175 degrees C).
2. In a bowl, cream together the butter, brown sugar and white sugar.
3. Beat in the eggs one at a time, then stir in the peanut butter, water and vanilla.
4. Combine the flour and baking soda, stir into the creamed mixture.
5. Finally, stir in the rolled oats, chocolate chips, and nuts.
6. Drop by teaspoonfuls onto an unprepared cookie sheet.
7. Bake for 8 to 10 minutes in the preheated oven, until the cookies are lightly toasted on the edges.
8. If you want the cookies to stay softer/chewier, remove from the baking sheet immediately to cool on wire racks.
