I remember Grandma making them for me when I was growing up. They were an especially nice treat when I was in college and would receive a tin!
You can make them with crunchy peanut butter or smooth & creamy.
My mom wrote the recipe down for me when I left home as a newlywed in 1985 when we were college sophomores.
Peanut Butter Cookies
1 cup (2 sticks) butter
1 cup peanut butter
1 cup sugar
1 cup brown sugar
1 tsp vanilla
2 1/2 cups flour
1 1/2 tsp baking soda
1/2 tsp salt
Cream butter, peanut butter, sugars, eggs, and vanilla. Sift together your dry ingredients and add into your creamed mixture.
Or you can be lazy like me and add in the baking soda and salt first to make sure it gets into the creamed mixture really good, then add your flour, without sifting any of it.
Shape into 1-inch balls, or something like that. Roll in more sugar. Place on your cookie sheet and criss-cross each cookie with a fork. I have to dip my fork in the sugar so it doesn't stick.
Bake at 375 degrees for 10-12 minutes. You might need to adjust this, because when I use my dark cookie sheet they get really dark and crunchy at 10 minutes. But we like chewy cookies.
This makes about 5 dozen cookies.
I won't even tell you how many I ate the first day, except that it was less than a dozen.
