Let’s get right to cake decorating, shall we?

GIANT CUPCAKE PAN

Giant Cupcake Pan with a heating core

To bake the cakes I used my Giant Silicone Cupcake Molds. When using a giant cupcake pan it is best to use a heating core to ensures even baking.

As I don’t have a heating core I always use a flower nail instead. Even for large 12 inch cakes. Flower nail always worked for me. I coated it with butter and flour.

For this super simple Willy Wonka cake I used my basic sponge cake but you can use a pound cake, chocolate cake, carrot cake.

Also, I torted both, top and bottom cake layers.

CAKE FILLING

Raspberry Jam and Buttercream filled cake

I love a generous dose of jam in the cake. To fill the cake I used raspberry jam and Vanilla Swiss Buttercream.

Use a spatula to crumbcoat the cake and chill until firm, about an hour or so.

ICE THE CAKE

To ice the outside of the cake I also used Swiss Buttercream. Are you wondering how I achieved bright purple and green colors? Follow my How to Color Swiss Buttercream tutorial.

It’s easier to ice the bottom of the cupcake cake when you turn it upside down. Having narrow end up and wide end down. Be sure to use a round cardboard cake board on the bottom and top.

Then chill it and turn it again so the wide part is up and narrow is down, just like it should be. You can watch how I did it the video below.

Then proceed to crumbcoat the top of the giant cupcake. Chill for 30 minutes and then with a Grass Piping Tip make the grass with green buttercream. Make sure to leave a section without piped grass for a chocolate river. Chill the cake until ready to add rest of the decorations.

COLORING FONDANT

To make all the rainbow lollipops, candy canes and mushrooms I used fondant. I used my Small Batch of Marshmallow recipe. I let it rest in the fridge for an hour before using.

Then I cut the fondant it in half. I kept one half white and divided other into 6 equal portions. I colored each with a get food color.

  • Few things to remember when coloring fondant:
  • Wear gloves
  • Have Crisco and cornstarch on hand
  • Use a silicone mat
  • Kitchen towel to dry your hands after washing

It’s best to wear gloves when coloring fondant. If you get color on you hands don’t panic. Try using Barbasol Shaving Cream to wash your hands. It usually does the trick for me.

To color fondant I first make a well in the center. I add few drops of color in the well. While kneading in the food color I also add about pea size of crisco and knead it in with the gel color. If for some reason fondant becomes too sticky I knead in little bit of cornstarch.

Test if fondant is thoroughly colored by cutting it in half. Check if color is even on cut sections. Knead little more as needed.

Be sure to wrap each colored fondant ball into plastic wrap to prevent from drying out.

QUICK GUMPASTE WITH TYLOSE

Tylose is great for making quick gumpaste. Knead 1/2tsp of Tylose Powder into about 1/4 cup of fondant. Use immediately. Cover remaining quick gumpaste while working to prevent it from drying out.

Fondant treated with Tylose powder dries significantly faster than fondant. It also dries hard.

GUMPASTE/FONDANT DECORATIONS

All the decorations need some time to dry, 2 – 3 hours. They can be made ahead of time. Store them in an airtight container until ready to use.

Mint fondant candies

Make candies, rainbow lollipops and candy canes. Watch the video tutorial below to see how I made them. Lollipops are so fun to make.

MUSHROOMS

Make variety of mushroom sizes. It is best to make mushrooms in steps.

  • Shape the cap using red quick gumpaste. Press a small flat white piece on an underside. Using a fondant ball tool make a hole for the tip of the white stem. With a tootphick make the gills lines. Let dry.
  • Shape the white stem. Insert a toothpick and let dry.
  • Using edible glue attach stem and the cap. Keep the mushrooms upright. Let dry.
  • Attach small white dots onto the cap. Use a little bit of water for the glue.

Piping chocolate river onto a cake

We can’t have a Willy Wonka cake without a chocolate river, can we?! With Chocolate Swiss Buttercream and a Round Piping tip pipe the chocolate river. Start at the bottom of the purple cake layer and continue all the way up the grass cake tier.
