Spray whipped cream on one aside of a cookie and set it on a plate. Spray another cookie and stick it on the first. Keep doing this until you have a stack of five. Then turn the stack on edge to make the start of a "log". Continue adding as many cookies as you have room for. Refrigerate at least 4 hours before serving so cookies will soften. When ready to serve, spread with more whipped cream to cover cookie log completely. Add colored sprinkles. Cut diagonally so each piece is striped.
