For Parshat Pekudei, Shabbat Shekalim, and Rosh Chodesh, I made silver and black cookies. Some of the cookies were half glazed with white frosting and then sprinkled with silver sprinkles (the half shekels). Some had a mere sliver of silver sprinkle covered white frosting (the new moon).
This is super easy: just stick pareve coins in the top of cupcakes glazed with melted chocolate chips.
For the cupcakes, use the vegan Moosewood chocolate cake batter or the Amazon cake batter in cupcake pans, 350 degrees for 20-25 minutes. Vegan batter means the little ones can lick the spoon because there are no worries about raw eggs. For the frosting, just sprinkle chips on the warm cupcakes and let the kids spread it around when the heat from the warm cupcakes melts the chocolate.
