Grey/black streaky buttercream pushed out of a decorating bag with NO tip. Make lumps and press them flat with your finger. Freeze and place whenever.

This is my favorite recipe for making rocks. I made a batch of this, colored with a touch of brown and black and they look absolutely real, like lava rock. Whatever you don't use keeps well in a covered plastic container for whenever the need arises. (I know, I've been glad to have them on hand...)

Sugar Rocks Receipe
Make royal icing with one fresh egg white and powdered sugar until it is piping consistency. Whip as much air into this icing as possible. Color unevenly. To get the streaked effect dont thoroughly mix the color through the royal icing. Cover with a damp cloth and reserve.
Line a shoe box with heavy duty tin foil. Grease the inside surface of the tin foil on the inside of the box with Crisco.
Melt 4 1/4 cups of granulated sugar in 1 cup of cold water over a low temperature in a large sauce pan. Bring to a boil and cook to 280º F on a candy thermometer. Remove from the stove and immediately stir the well beaten royal icing into the hot sugar syrup. Pour into the (greased foil) lined shoe box (or a container of comparable size). This mixtures original volume will grow and bubble up - doubling its volumne. Let cool completely and then break apart for wonderful textured rocks.
For fine grains of sand or gravel these rocks can be crushed or broken into small pieces.

I think it will be perfect for your fire pit. Good luck,

I made rocks recently out of black and brown marbled MMF. Just swirl and let the kids roll them out, worked like a charm!

I made a firepit with rocks. The easiest thing to do was make little rock shapes with pieces of extra fondant (or extra pieces of tootsie rolls in your case), then put them in a small container with some grey luster dust. Shake up the container to coat all the "rocks", and you're set. Mine are silvery because I didn't have a dull grey dust, but this should give you an idea of what it would look like:

I marble white, brown, gray and black fondant or modeling chocolate. Pull off small pieces and roll them SLIGHTLY to resemble rocks. Let them dry and place however you want them.

You can buy chocolate rock candies. I find them in the bulk section at my grocery store. They are really yummy icon_biggrin.gif
