Princess Castle Cake!

Are you ready for this?  This may have been the most time consuming cake that I have ever made at  almost 6 hours from start to finish, but it was totally worth it to see the birthday girl admiring it!

 Rapunzel, Rapunzel let down your hair!  I just love this cake!!!
I honestly didn’t have any plans when I set out to make this cake (hence the long time it took to make it).  I looked online for princess cake’s to get some ideas, but in the end I just didn’t see what I was looking for!  I think this cake is sure to please any little girl that loves princesses!!! Now I will have to warn you that this is not a beginners project.  I will say though that this was my first time working with fondant… and I loved working with it!  I actually made the fondant myself and it tasted really good.
Here is what you will need to replicate this:  you can change decor to make your own look too!
I used 1 white cake mix and 2 chocolate cake mixes (and items to prepare them from the box)
sugar cones and ice cream cups
chocolate rocks (found mine at walmart!)
2 bottles of pearlized white sprinkles (they look like little pearls)
1 bottle of tiny white sprinkles
purple gel food color
aqua gel food color
1 large kit kat bar
piping bag
several tips: I used a mini shell tip, flower tip, and line tip along with a large tip for filling in areas.
2 batches of fondant: recipe here
2 batches of buttercream icing recipe here

1 9×13 rectangle cake pan (you can bake different flavors see tutorial here)
rectangle cake board… big enough for a 9×13 cake- so about 12×14 or so.
4 toilet paper rolls
large oatmeal can
ribbon, princess doll and anything else you want to decorate with!

Let’s get started!  Bake your cake according to the directions on the box.  I used 3 cake mixes for mine.  If you use 3 mixes it take a little longer to cook so make note, but just make sure the cake bounces back when you press it and toothpick comes out clean.
 Cut the cake in a 9×9 square and 2 4×4 squares like picture above.
 Start icing the bottom layer then use fondant to cover the bottom layer first.  Put a little icing where the llayer will go… Then place one of the 4×4 squares on top of that.  Put icing on that and layer it again.  Ice the 2 top layers and place fondant over them.
 Make your fondant according to the directions.
 Now on each corner take your TP roll and cover it with fondant.  Carefully take the covered TP roll and cut it through one of the corners of the cake.  Repeat with each roll.
 Spread some icing out on the space in front of the cake.  Build up your rock section first.

 Next make some custom colored sprinkles for the water.  I made an aqua color using a little tiny bit of food coloring mixed in a plastic bag with the pearl sprinkles and the tiny sprinkles.  I also make purple sprinkles too for the rest of the design.
 Lay the sprinkles out to dry on a paper towel for a minute after mixing with the color.
 Place sprinkles out on top of the icing next to the rocks.  I also cut out an oatmeal container for the bridge.
 Ice the oatmeal container and place Kit Kats on top… Note that I ended up making the bridge go on top of the first layer of the cake in the final design.
 I used paper straws and ribbon for the bridge rope.
 The towers were made using an ice cream cup cone with the top outer layer covered with icing and dipped in sprinkles and placed inside the TP roll.  I used a mini shell tip to make the outline after placing a sugar cone on top of that.  The sugar cone has a ball of fondant rolled in sprinkles with a cut paper straw and ribbon.
 The custom sprinkles are SOOO pretty!!!  I love the rocks too.
 Rapunzel was perfect for this cake, but any small 3-5 inch princess would work.  The sugar cubes are placed around each layer also using a dab of icing on each one to keep it down.   And that completes this lovely cake!!!
 Isn’t it stunning?  I really think that it was worth it!!!
How about you?  Have you or would you make a cake like this for a birthday party?  Or am I just crazy…lol… you don’t have to answer that one… I think we all know! haha
Happy Creating!!!

Wow! I love this!! My mom made me a Princess cake which was like a dome cake for a skirt with a doll torso on top which was the stuff of dreams! This is even more amazing! Love how you decorating with normal materials, sometimes I feel people believe that they can only decorate a fondant cake using sugarcraft. Thanks for sharing such a creative cake! :) I'm still finding my feet on the blogosphere so would appreciate any support/advice you can give! x
