Treat fans of ancient Egypt to a pyramid-shaped cake. Despite the mystery over the construction of the pyramids, building such a cake is more straightforward. While you could use a pyramid-shaped cake pan available from speciality baking stores, you can also use sheet cakes -- which gives you the ability to add fillings.
Frost the top of one 12-by-12 inch sheet cake with frosting or other cake filling, then place the second sheet cake on top. Press lightly to stick the two together.
Trace a square onto the top cake that is 2 1/2 inches in from the edge of the cake using the tip of a cutting knife.
Hold the knife at an angle, and cut from the traced line on the top of the top cake to the bottom edge of the bottom cake. Repeat on all four sides so that the cake looks like a flat-top pyramid.
Take two of the side pieces that you cut away and place them together on top of the cake. The cut sides of these portions should be facing outward. This will make the angle match the sides of the bottom of the pyramid.
Trim the top two pieces of cake on the sides that overhangs, holding the knife at the same angle you did to cut the bottom pieces of cake. This will make your pyramid-shaped cake.
Frost the pyramid cake with brown or golden frosting. Sprinkle toasted coconut onto a foil-covered cake board to look like sand, then transfer the frosted pyramid cake to the cake board.
Add toy palm trees, a miniature sphinx or other Egyptian figurines.
