Peanut Butter Cookies - the United Nations of cookies

There is an amazing amount of agreement for peanut butter cookie recipes. This is not my recipe, but, apparently, a recipe from the global community. You might find variation on how the instructions are written, but the ingredients stay pretty much the same, in the vast majority of online and book sources.

1 cup (8oz/228gr) butter, room temperature
1 cup (9oz/255gr) creamy peanut butter
1 cup (7 ounces/200 grams) packed brown sugar
1 cup white sugar
2 eggs
1 tsp baking soda
1 tsp baking powder
1 tsp vanilla extract
2½ cups flour

1. Cream butter, peanut butter and both sugars together.
2. Add eggs, one at a time, beating well.
3. Add baking soda, powder and vanilla.
4. Stir in flour.
5. Wrap and put in the refrigerator to rest for 1 hour and up to 72 hours.
6. Preheat oven to 375°F.
7. Roll into balls, place on an ungreased cookie sheet, and flatten, using a fork, to create a grid pattern.
8. Bake for 10 minutes depending on the size of your cookies (bottoms should just start to colour if you wanted to check).
