Sonic the Hedgehog Cake

Yesterday my baby turned six!  During this past summer he announced that he wanted a Sonic party for his birthday.  Due to the fact that my four children and I were pulled into a slot at 3:58 pm ordering half price beverages from roller skating attendants at, you guessed it, Sonic, I assumed he meant that type of Sonic party, a Sonic the-very-popular-in-Texas-fast-food-restaurant party.  My mind immediately went to visions of gum paste tater tots and fondant corn dogs dancing on top of a sprawling sheet cake and a good game of 'Pin-the-Straw-on-the-Cherry Limeade".  My older son, however, quickly clarified that he thought his little brother meant Sonic-the-Hedgehog from the cartoon and video game.

Oops, likely mistake!  I quickly shifted gears, although the other type of Sonic party does have it's appeal, and plotted my Sonic the Hedgehog party including the cake.  I followed my own tried-and-true birthday cake decorating tips.  I interviewed my son to find out what he envisioned for his birthday cake, I studied other Sonic cakes that I found on the internet, and I purchased a few Sonic figures from Toys R' Us.  I also decided on a cake and an icing recipe, gathered all of my cake decorating paraphernalia, and purchased an ample supply of baking ingredients and embellishments.  Despite all of this obsessing planning, as is usually the case when I create cakes, I had no idea how the cake would actually turn out until it was completed.  After the fact, however, I can share that these are the steps I followed to create my Sonic the Hedgehog cake.

 Steps for creating a Sonic the Hedgehog Cake
  1. Mix up a double batch of your favorite cake.  I used Anne Byrn's Birthday Cake for a Crowd from her book The Cake Mix Doctor Returns.  This is a moist yellow cake with a prominent vanilla flavor.
  2. Bake half of the batter (which is one batch) in a round 14 inch round cake pan.
  3. Bake half of the other half of the batter (which is half of one batch) in the 9 inch round cake pan.  I baked my extra batter into 12 cupcakes which my family enjoyed on our son's real birthday.
  4. Allow the cake to fully cool.  Either decorate the cake right away or tightly wrap it in plastic wrap and refrigerate.
  5. Make a double batch (six cups) of your favorite Buttercream Icing.  Although I usually use the recipe that is on the side of the Domino's Confectioner's sugar box or one of the Cake Doctor's frosting recipes, this time I used the recipe for "Wilton Buttercream Icing" which was printed on the back of the 14 inch round cake pan insert.  The difference between the recipes is that the Wilton one includes a combination of butter and vegetable shortening and the Domino's one calls for just butter. Tint the icing blue using gel icing pastes.
  6. Place a dab of icing on a 16 inch cake round.  Edge the cake round with two inch strips of wax paper. Place the cake in the center of the cake round.
  7. Using an offset spatula, frost the 16 inch cake with blue frosting.  If you are a nonprofessional like me, read this article at Whisk Kid on "How to Frost a Cake".  I gathered many tips from this post.
  8. Center the 9 inch cake on top of the fully iced 16 inch cake.  Frost the 9 inch cake.
  9. Using a bench scraper and a offset spatula, smooth the frosting.  Remove wax paper strips from beneath cake.
  10. Gently press mini-oreos into the bottom edge of each cake.  
  11. Crush more oreos in the food processor until fine crumbs are formed.
  12. Edge the 9 inch cake with yellow M & M's.
  13. Place a 3 inch bowl in the center of the 9 inch cake.  Using a spoon, sprinkle Oreo crumbs around the bowl and spread to the M&M edge to create a road.
  14. Slowly remover the bowl.  Place more yellow M&M's around the inside edge of the cookie crumbs.
  15. Pipe yellow dashes along the center of the cookie crumb road.
  16. Using Wilton icing decorations spell Happy Birthday along the edge of the 12 inch cake.
  17. Place Sonic the Hedgehog figures on the cookie road.  Place candles inside the road.
  18. Cover loosely with plastic wrap.  Place in refrigerator if serving time is over a few hours away.
  19. Take lots of pictures!  Serve with a smile!
Add lots of icing for the crumb coat.  Remover excess with a bench scraper.
Use an ice cream scoop to place more frosting on the cake as needed.
Smooth frosting as much as possible with an offset spatula and bench scraper, but then accept that the imperfections add to the charm of the homemade birthday cake. 
Use mini Oreo cookies (like race wheels) to accentuate the edge and further hide any imperfections.
Use yellow M&M's to edge the race track.
Use a bowl to create the cookie crumb race track.
Take deep breaths and embrace imperfections.
Perch Sonic and his pals on top of the cake along with some pre-made letters to spell out "Happy Birthday!"
Bask in the glory of a homemade cake!
