Fossil Cookies - baking and science combined!

April 5, 2017


 Take a look at the fossil cookies that were made by the white house class. Do you recognize any of these prehistoric fossils? This is a fun recipe to make at home! 



1 cup walnuts, toasted

2 1/4 cups all-purpose flour, plus more for dusting


2 sticks unsalted butter, room temperature

3/4 cup plus 2 tablespoons confectioners sugar

1 teaspoon vanilla extract




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. 

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

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. 

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