Remove filling from cookies and place in a mixing bowl. Set the cookies aside. Remove the icing from the top of the Honey Bun, add to the cookie filling, and mix until smooth.
Crush the cookies thoroughly by placing them in a storage bag and pounding with a heavy pan, rolling pin or meat pounder. Small pieces will remain despite your valiant efforts and that is fine - it adds character. Place the cookies in a separate bowl.
Add water to the crushed cookies, one tablespoon at a time, mixing after each addition. Continue to add water just until the mixture forms a dough that holds together without crumbling. Knead the dough thoroughly before deciding to add more water. Just keep in mind that it is like when using legal, prescribed drugs: you can always take more, but you cannot take less once they are in your body.
Divide the cookie mixture into two, ensuring one section is slightly larger than the other. Flatten the cookie cakes with your palms to form two ¼” thick cakes that are larger than the Honey Bun. One of the dough cakes should be slightly larger than the other.
Set the Honey Bun on top of the smaller dough cake, ensuring there is a margin of dough around the edge of the Honey Bun. Drape the larger dough cake over the honey bun and join the edges into the bottom half, pressing together to seal and encase the honey bun to make one hefty cake.
Remove the icing from the bowl and knead with your hands. It should still be a little sticky but will become less so as you mold it in your hands. Flatten the icing into an oval that is slightly larger than the cake. Place the icing on top of the cake and smooth it down the sides.
Cut the cake into 1-inch slices using a sharp knife or metal ruler. A metal ruler works better than a knife, and also - rulers are allowed in prison. When you are finished cutting the cake, put the ruler away or else someone will steal it while your back is turned, just as mine was the last time I made this cake.
Pose handsome - the easiest step, just smile, then post. It can be enjoyed as-is, or slices can be warmed in the microwave for 10-15 seconds.
