Okay, this was really fun! I used NFSC for the cookie and then used the same cookie cutter to cut the cone out of brown fondant and then a small roller to get the cone design. For the ice cream part I cut a larger circle out of orange fondant and cut off a straight edge. I put a small scoop of buttercream directly on the cookie and then laid the orange circle over that and sealed the edges. All of this was done as soon as the cookies came out of the oven.
