Directly into a 9- or 10-inch cake pan, measure out the flour, sugars, salt, and cocoa. Mix together thoroughly so it appears that you have a light brown moon sand.

Make a large crater in the center of the pan, a medium crater on one side of the big crater, and a small crater on the other side.

Spoon the baking soda into the medium crater. Measure the vanilla into the smallest crater. Pour the melted butter into the largest crater.

Pour the vinegar into the medium crater, right on top of the baking soda, so that the volcano erupts and lava flows over the surface of the moon.

Once the volcano subsides, pour the milk over the surface, flooding the moon.

Stir everything together until you have a nice batch of moon mud.

Now toss your chosen meteorites onto the surface of the moon.

Bake for about 35 minutes, or until a toothpick stuck in the cake’s center comes out dry.

Let the moon cool in the pan, then slice and serve.
