3. Use the cookie stamp side of the tile (without the border) and dust mold thoroughly with all-purpose flour to prevent the dough from sticking to the mold.
4. Form half the dough into a large round ball, and keep rolling it round and round until it is smooth as you can get the outside surface. Dust lightly with flour to keep it from sticking to the mold. Place on cookie sheet on a piece of parchment paper (to keep from sticking to cookie sheet).
5. Press the dusted tile down onto the dusted ball of dough – gently, with a rocking motion, until it is about 1/2" thick.
Gently lift the tile off of the cookie. You may see impressions on the 4
sides where the edge of the tile made a mark on the dough (right).
These can be smoothed out with a dampened finger so cookie looks smooth
all the way around (see photo below right).
7. We baked our giant cookie at 350° F. for 30 minutes.
