We made super easy peanut butter cookies...we mixed together 1 cup of peanut butter, 1 cup of sugar, and 1 egg.
We rolled the dough into balls and pressed imprint "fossils" into the dough using our playdough stampers. We baked the cookies for 8 to 10 minutes at 350.
Fun and simple!
(please excuse E's dirty fingernails...they are not actually dirty, but are dyed with tie-dye).
The inspiration for making fossil cookies came from here.
