The best way  to get started making shaped cakes is with the Wilton pans. You can  find Wilton shaped pans at craft shops with cake supplies (Michael’s,  Joann’s etc.) for $10-15/pan. You can also find pans at garage sales,  e-Bay or order online from Wilton.  Here is a link to the Wilton website  showing all the shaped pans. http://www.wilton.com/shapedpans/   The pan will come with instructions for how to decorate the cake shown  and (usually) a few variations.   (Instructions are also online, if you  have an older or used pan.) 
Use  your imagination to branch out.  I have a Teletubbies pan that my mom  picked up off a clearance rack when the kids were tots. I was in the  attic for a few years, but then I used to make a cake for a laser tag  party… Dipsy and LaLa became boys in laser tag vests.  They could easily  be Luke and Chewbacca! 
 
 
The Sports Ball cake is shown as a soccer ball, baseball, etc.  It makes a good Death Star.  It also made the Geode cake below, which is one of the easiest cakes to make.
Spend  a few minutes at a shop with cake supplies to get an idea of what’s  available. I also recommend that you spend some time looking at the  Wilton website – it’s got tons of information on how to decorate cakes,  cupcakes, etc. I am totally self-taught from this website, other cake  decorating sites and trial/error. The stuff is actually not that hard,  it just takes a bit of practice to make it smooth. Assume you can, and  you will.  (Or to paraphrase Yoda: If you believe, you will not fail!)  http://www.wilton.com/cakes/  or http://www.wilton.com/decorating/browse.cfm  
 
 
The  shaped cake pans are very easy to use – they hold one standard box cake  mix. Spray the pan liberally with cooking spray. Then just mix the  recipe on the box, pour into the pan and bake as directed for a sheet  cake on the box. Do check the cake a bit early in case it cooks faster  in the pan. When done, flip the cake out of the pan onto a wire rack and  let cool completely on a wire rack. Completely cool – you cannot  decorate a warm cake! 
 
 
To decorate, follow the instructions on the cake pan, but feel free to improvise. Here are the basics:
 
 
1.       Start with Good Basic Buttercream Icing 
Box  cake mixes are wonderful, but canned icing is not!  Start with homemade  Buttercream Icing.  It tastes wonderful, has no trans fat, and is easy  to make and use.  
                Buttercream Icing  Recipe 
2 sticks (1 cup) unsalted butter – room temp if possible.
1 stick (1 cup) Crisco – not butter, just the plain ones
2 teaspoons real vanilla extract
2 lb powdered sugar (1 large bag) – sifted if it is at all clumpy
6 Tablespoon milk
 
 
2 sticks (1 cup) unsalted butter – room temp if possible.
1 stick (1 cup) Crisco – not butter, just the plain ones
2 teaspoons real vanilla extract
2 lb powdered sugar (1 large bag) – sifted if it is at all clumpy
6 Tablespoon milk
Cream  the butter and Crisco thoroughly. Mix in the vanilla. Slowly work in  the powdered sugar, a bit at a time, alternating with TSPs of milk. This  is the base frosting. You can tint with food coloring as you like. I  use the Wilton pastes – there will be a rack of these little pots in the  cake aisle. Note that the color will get a bit darker as the frosting  dries. 
 
 
Note:  this recipe does not produce a true white icing, since both the butter  and the vanilla have color. If you are going to color the icing, it  doesn’t matter at all. If you want to work with whiter icing, buy a  bottle of “clear vanilla” – right next to the real vanilla at the  grocery store. 
If  you want truly white, you have to swap the butter for Crisco, so no  butter and 2 cups Crisco. This seriously affects flavor, so compensate  by adding ¼ tsp of butter flavoring. (Available at grocery store or  craft shop cake isle.)  But my theory is that the “butter white” is fine  for everything except wedding cakes. And it tastes the best.
To  color the buttercream, use any food coloring. I personally use the  Wilton pastes from the cake aisle as they have a wide assortment of  colors, work with all frostings and fondant, and last for a very long  time. You can also find liquid food coloring and powdered food coloring.   Note that it is virtually impossible to tint the buttercream true red  or black. Start with a cake with easier colors, using tubes of red/black  icing to provide details.
 
 
2.       Supplement your homemade icing with Wilton tubes of colored icing as you like.
I  always use the tubes to accent in black and red, colors that are hard  to make at home.  The reindeer shown is made with homemade buttercream  for the white and tan, but I used tubes for the red, green and black.  I  also use tubes if I need a bunch of colors – such as the “sail into  summer” cakes. You can find the tubes in the cake aisle at Michael’s  Joann’s, etc. 
 
 
Tip:  you can get icing tubes at the grocery store too. These are usually  Cake Mate brand. They are fine, but the Wilton tips discussed below don’t fit  these tubs. So be sure to pick up a pack of Cake Mate tips at the  grocery store too. (Or else be prepared to squeeze the Cake Mate icing  into a disposable decorating bag.) I use the Cake Mate tips, but they  are larger and less nuanced than the Wilton Tips. You won’t be able to  do as much with them, but they’re OK in a pinch.
 
 
3.       Decorating Tips and Tip Accessories
To decorate your first cake you’ll likely need some Wilton decorating tips.   Most cakes call for an “open star” tip – e.g. Wilton No. 16 or 18.  The  first thing to do is to make an open star. You will cover most of the  cake with nestled stars. They are SUPER EASY. To make the star, just  hold the bag straight up, squeeze out a star, LET GO, then (after you  have stopped squeezing) pull the tip up and away. Voila! Repeat. Snuggle  the stars close together to cover.   See:  http://www.wilton.com/technique/Star and  http://www.wilton.com/technique/Star-Tip-Border  
 
 
You’ll  probably also want a round tip, e.g., No. 2 or 3 – for outlining and  writing.  Some pans require other tips as well, – but many only require  open star and round tips. 
Here is a link to the Wilton tip info page, showing all the tips:
http://www.wilton.com/store/site/department.cfm?id=3E304FE9-475A-BAC0-542C86E6718519F9&fid=3E305C8B-475A-BAC0-54E61BA4686884CF

The  Wilton website has detailed instructions for how use each tip, and how  to create designs, such as ribbons, flowers, etc. Start with the open  star, then work your way through. 
 
 
Tip: It’s  a pain to try to use the same tip for different colors – if you want to  use 3 colors on the cake (e.g., using the stars), buy 3 tips so you  have for each color.  It’s a huge pain to wash the tips between colors,  and you will invariably want to swap back to touch up. The aggravation  will put you off. It’s not that expensive to have several of the most  popular tips, and a much better approach!  Trust me.
You use the tips with a decorating bag.   Buy a box of disposable decorating bags at the craft store.  Do NOT buy  the reusable bags – they are impossible to wash.  Disposable is the way  to go. The bags are perforated, separate into clear plastic triangle  bags. You’ll snip off a little bit at the end of the bag and drop in  your decorating tip.  Make sure the hole isn’t too big, otherwise the  tip can pop out.
 
 
Tip:   get a big box of bags.  They are useful for many things.  For example, I  like to melt chocolate in the microwave, fill a bag, snip the bottom  & drizzle on cookies, strawberries, etc.  Looks really fancy, takes  just moments… You can also let the kids decorate cookies, ice cream,  etc. with them. Very fun! 
 
 
The tips also work with the Wilton tubes of colored icing.  To use them, purchase a plastic coupler ring.  These will be available near the tips.  Using the ring, you can attach the tip right to the Wilton icing tubes. 
If  you like, you can also purchase a full coupler set for your tips.   These work with the decorating bags, so the coupler goes inside the bag  and the tip is held on from the outside with a ring.  The advantage of  this is that you can swap different tips on the same bag.  The  alternative is to just put your icing into different bags, one for each  tip you want to use.   I find the couplers convenient, but they are not necessary. 
4.       Decorating the Cake
To decorate, place your cake on a board or plate. A word about boards…
·         Cakes are heavy, and there is nothing worse than trying to move a cake that isn’t on a sturdy surface.   Big cakes weigh a TON. 
·         Make  life easy, go to Home Depot and buy a large square of plywood or  particle board. Then go to party city and buy a plastic table cloth (or a  roll of plastic) to cover the board. Just cut a piece and tape to the  bottom of the baord. (You can also use generic aluminum foil – don’t  waste your money on Wilton “cake foil” – you don’t need this!) Cover the  board with the plastic/foil, then position the cake as you like. If you  look at my cakes, almost all are on a piece of wood that my better half  cut for me, covered with blue plastic from a big roll I got years ago.  The nice things are (1) I know the cake will fit, and (2) I can decorate  on the plastic, and if I make a mistake, it wipes off cleanly. I  usually write on the plastic – it’s totally forgiving. 
 
 
·         If  you put the cake on a cardboard cake plate (a “round”), be careful  because the cardboard gets “stained” by the fat in the buttercream. If  you use these rounds, cover with foil or plastic – or else by  pre-covered rounds.  Thick rounds (called cake drums) are very nice to  use, but expensive. 
Once  the cake is set on the board, ice the sides of the cake, just using a  spatula or a knife. If the cake has a lot of crumbs (e.g., if you have  cut it or leveled it), use 2 coats. Allow 15 mins for the first “crumb  coat” to set. Make sure you ice all the way up to the pattern on the top  of the cake! 
To  decorate the main part of the cake, put about a cup of frosting in a  decorating bag with the tip, and pipe the stars onto the top of the  cake, following the pattern and the instructions. (Improvise as you  like!) 
 
 
If  you are doing a character cake, the hardest part is always the eyes.  You can follow the Wilton instructions for decorating the eyes with  buttercream, but I’m often dissatisfied by the result. The instructions  will tell you to dip a finger in cornstarch and pat the buttercream  smooth. First, you need a really dry finger, not one covered in  cornstarch. So just wash/dry your hand well, and rub a bit of cornstarch  or powdered sugar on your hands for extra dryness. Use a clean towel to  remove excess powder - it will make your cake look dusty (esp the black  part of the eye). Then just gently pat the frosting to make it flat and  smooth. This works best with the icing from tubes, rather than the  homemade icing. 
 
 
The  alternative... if you want super cute (and super easy) “cartoon” eyes,  splurge on a box of fondant.  See my post on Fondant for info on this. 
5.       Final Thoughts
·         Don’t be afraid to use other things for decorations, esp candy.  Kids love to see candy on the cake! 
·         To  finish the cake, do a row of stars around the base.  You can also  finish with candy.  For Christmas cakes, I finish with white frosting  stars, then stick a red or green M&M in each one. So easy, but very  festive, and it also covers up any imperfect stars perfectly!   (And the  kids love it!) 
 
 
·         If  you screw up, just scrap off the frosting and start again. No one will  ever know. (But don’t worry about little mistakes – people truly do not  see flaws, they only see the coolest cake ever, because you made it for  them!  
·         When  you’re done, toss the tips and couplers in the dishwasher silverware  basket and toss the bags in the trash. Extra icing will keep in an  airtight container – and do keep the extra icing until the cake is  served, just in case it gets bumped! Wrap leftover fondant tightly in  plastic wrap and store in a tightly sealed zip top bag. 
·         Once  you get the hang of decorating the shaped cakes, per the instructions,  branch out. I have a great “football” pan – have never made a football  cake, but this pan created the bodies for both the gator and the  manatee… I have a sports ball pan. Have made various balls, but this pan  also made the geode cake and the death star… 
·         Play  with the techniques too. If you do open stars with green icing on a  sugar ice cream code, viola! You have Christmas trees… I once topped a  plain white sheet cake with 3 Christmas trees and a package of little  plastic animals I picked up on the clearance at the Disney store –  Bambi, Thumper and the skunk – and had a cake for a Christmas party that  the kids are still talking about. The hardest part was having the idea!  
 
 
·         If  you need more cake, you can bake 2 cakes using the same shaped pan and  stack them (like any layered cake) – decorating the top.  If you stack  the cakes, try to level the layers by slicing off the hump on the top  (when baking) side. This takes a bit of practice, but it’s important to  keep the cakes from cracking. You can use a serrated knife, or else buy a  leveler – they haven then on the cake aisle. (If you buy, get the  biggest one.)  See: http://www.wilton.com/cakes/making-cakes/leveling-cakes.cfm   
Or  else do 1 cake and a set of cupcakes. If you do cupcakes, you can  usually find some cool decorations to complement the cake – e.g., to  complement a dinosaur cake, get a set of small plastic dinos at Party  City or Toys R Us, and put one on top of each cupcake.   I extended the  geode cake with several batches of cupcakes – frosted them white with a  piece of rock candy on top.  Super easy! 
·         Next time you make cupcakes, use a big star tip to decorate.  They will look so pretty!
Example:  Reindeer Cake, made with Wilton Rudy Reindeer Pan 
         1 box cake mix, decorated with 1 batch of buttercream for the  white/tan/brown, used tubes for back, red and green, plus gumdrops and a  sour candy for the red nose!  Iced using open start and writing tip.
Example:  Easter bunny cake, made with Wilton Blues Clues Pan - white buttercream open stars
