I love these cookies. So simple and only 3 ingredients. There are hundreds of nearly-identical recipes for this on the Internet.
Flourless Peanut Butter Cookies
3/4 cup creamy peanut butter
3/4 cup sugar (a combination of white/brown sugars is ok)
1 egg
3/4 cup sugar (a combination of white/brown sugars is ok)
1 egg
Preheat oven to 350F. Mix egg, sugar and peanut butter together. Roll into balls, whatever size you want.
Place on an ungreased, parchment-lined cookie sheet. Flatten with a fork, making a crisscross pattern.
Bake for 15 minutes at 350°F. Cookies are done with they are light brown and a little shiny in the middle.
