Stacked Cakes created this awesome R2-D2 cake that makes R2′s signature astro droid sounds and have even posted pictures of how they assembled it so that you can make your own.
This necessitated making his legs and feet out of non-edible, structural materials (wood and polystyrene). His body and head is made entirely out of choc mud cake and icing.
R2D2 was the perfect opportunity to add a sound module to one of our cakes. These modules allow the cake to make any noise you can imagine with the push of a button. Music, sound effects, engine noises, talking, anything at all is possible.
This video below shows of the cakes sound module.
Perfect for my husbands 40th in October! Going to give it a go although may not be as professional as this one!
