A dinosaur cake can be a sweet addition to a child's dinosaur-themed birthday party. You can make a three-dimensional cake that pops a bit more than a traditional, flat sheet cake. A dinosaur-shaped cake sits up and draws attention to itself. A professionally made cake like this can be costly, and you can bake and decorate one yourself without breaking the bank. A few basic baking materials and some other adornments are all you need to quickly put together a 3-D dinosaur cake.

Mix a basic cake batter of your choosing per the cake mix instructions. Pour the batter into a round cake pan and bake. Let the cake cool before handling.

Cut the cake in half so you have two matching half moon cake halves. Attach the pieces together by using some frosting as a glue to hold them together in a double-layer half moon shape. Set the piece sitting upright, with the round part up, on a baking tray.

Lay an oval-shaped snack cake on both sides of the upright cake at one end, and on both sides at the other end, to look like the legs of a dinosaur as it is sitting down.

Attach a round doughnut at the top of the cake on one end to look like the dinosaur's head. Attach it in place by sticking a toothpick through the doughnut and into the cake.

Cut two graham crackers in half at a diagonal so you have four triangular graham cracker pieces. Stick these upright into the top edge of the cake to look like the spikes on a dinosaur's back.

Coat the entire cake, Twinkies, doughnut and graham cracker pieces with green icing (frosting).

Draw eyes and a mouth onto the doughnut face of the dinosaur using coloured icing (frosting).


Let kids help decorate the cake with sweets and icing (candies and frosting).


If any pieces start to shift or fall, reinforce them with toothpicks.
