Ingredients

  • 1 cup walnuts, toasted
  • 2 1/4 cups all-purpose flour, plus more for dusting
  • Salt
  • 2 sticks unsalted butter, room temperature
  • 3/4 cup plus 2 tablespoons confectioners' sugar
  • 1 teaspoon pure vanilla extract

Directions

  1. Preheat oven to 325 degrees. Pulse walnuts in a food processor until finely ground. Transfer to a bowl, and whisk in flour and 1/2 teaspoon salt.

  2. Beat butter, sugar, and vanilla with a mixer on high speed until pale and fluffy. Reduce speed to low. Gradually beat in walnut mixture.

  3. Divide dough into eighteen 1 1/2-inch balls, and press into irregular stone shapes using the palm of your hand; transfer to a parchment-lined baking sheet. Dust food-safe plastic insects with flour to coat; press into dough to make fossil impressions. Freeze until dough is very firm, 20 to 30 minutes.

  4. Bake until golden brown and firm in center, 25 to 28 minutes. Transfer sheet to a wire rack, and let cool.

    I made these cookies using a bag of Halloween characters I found at the dollar store. I washed them with anti-bacterial soap and let them air dry. They worked great and I had some scary skeleton, bug, spider, and snake cookies. Great, delicious, and fun recipe.

    Oh, and you can also use shells, which are typically found as fossil imprints - Best Buy has a small bag for under $4!

    I found a small plastic bag with a variety of insects at Party City; you have to look in the party favours section, not the Hallowe'en areas. I also made a couple of dinosaur "feet" to make footprint fossils by cutting the shapes out of a cross-sectioned potato, as you would for childcraft stamping/printing. This is a great, classy variation to the more obvious ghouls and graveyards decorated foods to bring to a Hallowe'en party - thanks, Martha!

    Found what look to be the same insects on Ebay for $6.95 (that's w/ shipping)--that'll save me time, energy, and gasoline--oooh, hope they're the correct size.....

    I must make them, too. I couldn't find the plastic insects on the craftforless site either so while running errands today I checked Michael's, JoAnn's, Big Lots, and Target, to no avail. Guess I'll try finding them elsewhere on line--oh, maybe a party store.... Why is everything a QUEST???

    I'm dying to make these for my paleontologist 3-yr-old, but can't find the "food safe plastic bugs" on createforless. Any ideas?
