Eleanor's Peanut Butter Cookies

If you ever wondered how I started cooking, or where I got my tendency to change the recipes of others, this is where both started. You see, this is my mom's Peanut Butter Cookie Recipe. She took the recipe from a '60's-era Betty Crocker Cookbook, and changed it by a single ingredient. The original recipe calls for a combination of butter and shortening, but she found that if you used more butter instead of the shortening (a 1 for 1 substitution) then the cookies came out softer, and more flavorful.
Here's my mom's variation of the Betty Crocker Peanut Butter Cookie Recipe:

1/2 Cup granulated sugar
1/2 Cup dark brown sugar, packed
1/2 Cup peanut butter
1/2 Cup softened butter
1 egg
1-1/4 Cup flour
3/4 tsp baking soda
1/2 tsp baking powder
1/4 tsp salt

Mix together sugars, peanut butter, butter, and egg until smooth. Add all other ingredients and thoroughly mix them in. Cover and refrigerate for about 2 hours.
Set oven temperature for 350 degrees. Shape the dough into 1 to 1-1/4 inch balls by hand or using a melon-baller, placing them 3 inches apart on an ungreased cookie sheet. Press a checkerboard pattern into the top of each cookie with a fork. Bake 9-11 minutes until golden brown around the edges.
Remove from the cookie sheet and allow cookies to cool on a platter (they tend to fall apart if cooled on wire racks, unless supported by parchment paper.)
Optional: dip the fork into granulated (white or party-colored) sugar between pressing the checkerboard pattern into each cookie for an added decoration.
Tip: This recipe makes a lot of cookies, but you don't have to bake them all at once. The dough will keep in the refrigerator for a couple of days, or four to six months in the freezer. I like to make them into balls using a melon-baller, and then freeze them in a zip-seal freezer bag labeled with the expiration date. When I want fresh cookies, I put the frozen balls on a cookie sheet, press in the pattern, and bake them as directed.
