These are melt-in-your mouth delightful Homemade Peanut Butter Cookies.
Cream the butter, peanut butter, vanilla, and brown sugar.
Beat in the egg.
Add the flour, soda, baking powder and salt. Give the dry ingredients a quick stir to mix them before beating them into the sugar mixture.
Beat the dry ingredients mixture into the sugars until thoroughly combined.
Roll the dough into 1-inch balls and place on a baking sheet, three across and five down (that is, 15 balls spaced evenly over the baking sheet).
Flatten the cookies with a fork in a crisscross pattern.
Bake at 300 degrees for 15 minutes until turning just a bit brown, but still somewhat soft. Bake longer if you like them extra crispy.
Remove cookies to a cooling rack and when cool, store in an air-tight container.
