When I was first asked to make an Angry Birds cake, I have to admit, I didn't think I could pull it off.
I knew the hardest part would be making the birds and pigs, and if I could do that, the rest of the cake would be relatively easy. I researched pics online, and copied them as closely as I could using fondant. I made these over 5 days, so that they had time to dry out a bit before I needed to use them. While they are not an exact replica, the characters were actually a lot easier than I thought they would be to make.
To make the wooden structure and the sling shot, I used a cardboard base and then covered in fondant. I stuck skewers into the bottom of the "wooden" structure so it could then just be stuck into the cake. All the other decorations (nest with eggs, planks of wood & stones) were also made out of fondant. All decorations were made at least a day before needed so that they would harden.
The night before I covered the cake board in green fondant so that it had time to dry out a bit. The cake was a vanilla cake with vanilla frosting and covered in brown fondant.
Once the cake was done, it was just a matter of placing all the decorations on the cake and board. After that I did the name and age, and I was done!
The birthday boy was so happy with it, and his sister gave me the best compliment I could have asked for "it looks just like the game!" Given how worried I was that I wouldn't be able to pull this off, I was very happy with the end result.
This Angry Birds Cake is a three layer cake, bottom was vanilla cake with 4 different swirl colors to match the Angry Bird theme, middle was just plain vanilla cake, top layer same as bottom. I made the batter from a recipes I had (you can get scratch recipes on line also) and poured the batter into 4 bowls, used food coloring, mixed and poured into greased and floured 9 in circle pans. Each color was layered, blue, then green, then red then yellow. Icing was homemade with ingredients such as butter, powdered sugar, meringue powder, Crisco, milk, cream cheese, water and vanilla.
The cake was cooled and then frosted. Refrigerated while finishing the fondant Angry Birds. I had made most of them ahead of time keeping them on parchment paper in an air tight container. The letters were fondant cut outs used with alphabet cookie cutters. Everything is edible minus the toothpicks to keep the bodies on the cake. I used clear glitter gel (all I had that was clear) in a tube by Wilton since I didn't have time to make my own "glue" to fuse fondant pieces together. It did the job but make the back of the fondant gooey when trying to peel off when it was time to cut the cake.
The cake was covered in blue fondant. I had some cracks and ripples on the sides so I disguised them with the letters around the perimeter of the cake. Of course to a bunch of 9 years they didn't care. I was cutting everything very close to the last possible second so I am pleased with how this came out in the amount of time I had to do it.
