How to Make a Castle Cake

I started making this princess castle birthday cake from the towers. I knew that it will take a while to complete this castle birthday cake so I made the towers on one day and the rest of the cake the next day.

For the towers I used two types of ice-cream cones. The cup looking like cone was used for the tower, and the actual cone shape for the top. I doubled my recipe of royal icing (2 egg whites) and iced the cones used for the tower, but not for the top.

I glued one inverted cone on top of another to make each tower. I used a small amount if royal icing to do that. I piped some royal icing around the seal in-between the two cones and using tweezers, I placed some pink and violet hearts. The hearts were store-bought.

Once the icing on the cones hardened, I colored some of the icing green and piped the vines. I used tip #2 for the stem, and used a leaf tip #67 for the leafs.

I colored some of the icing pink and using tip #225 made the flowers. Then, I used yellow icing and tip #2 for the dot inside the flower.

I piped the flowers onto parchment paper and let them dry before using them. That way, if you make a flower that is not so pretty, you can just throw it out, or eat it, instead of having to correct it on the cake. I saved the flowers for later.

I also colored some coarse sugar with red food coloring by placing the sugar in a small sandwich bag and adding couple of drops of red color. I kneaded the bag to distribute the coloring and ended up with all different shades of pink sugar. I saved the sugar for the next day.

On the same day I baked the small round cake. I used my recipe for chocolate sponge cake and a 6" spring form. I poured the rest of the dough into another small form and baked them next to each other.

After that, I baked the bottom of the cake using 1/2 recipe of sponge cake recipe. Next time I would use 3/4 of the recipe to make the cake higher. I used a 9.5’’ (23 cm) square form. I placed both cakes in the fridge to make it crumb less during icing.

On the second day, I made one batch of buttercream icing. It was enough for me, but if you like to use a lot of frosting, then you might need to double the ingredients.

The eggs I used had yolks which had a deep yellow color. The icing came out as light yellow. I cut both of the cakes into two layers and soaked each layer with syrup. I smeared some of the icing on each bottom part and covered with the top. Afterwards, I iced the bottom square cake completely. castle birthday cake I cut drinking straw into pieces that were the same length as the bottom cake was thick. I placed the straws into the bottom cake to serve as pillars to support the top cake.

From cardboard I cut out a circle that was the same size as the top cake. I placed the round cardboard onto the inserted straws and the round cake on top of that. I strongly recommend you to do that. The last thing you want after all this work is a sinking top of your castle birthday cake.

Once the top of the cake was placed, I iced the whole cake. While the cake was cooling, I made from melted chocolate the windows and the door.

I placed the chocolate in a freezer for 1 hour so it would set faster. I would recommend doing that a day before, since the chocolate was melting rather quickly while I was placing it on the cake. To pipe the windows and door I used a regular syringe that I got from my kid’s doctor.

To attach the towers to the cake, I cut some of the corners of the cake and attached the towers using more colored royal icing. I piped the royal icing all around the towers to make sure that they don't fall.

Once the chocolate was cooled, I attached the door and the windows to the castle birthday cake. I made the white window lines with royal icing.

It is easier to first place the window on the cake and then to pipe out the white borders. I tried doing it the other way around and it was just messy. I attached the royal icing flowers and leafs to the cake and piped with leftover buttercream icing border all around the cake. For the border I used tip #18.
