School will be starting here soon and what better way to make your kids first day special than with cake? I cut a vanilla pound cake into the shape of a pencil. Then I used different colors of frosting and the star tip to decorate all the details. Also, if you want to make an end of the school year cake, consider making this Graduation Hat Cake.

Tips and techniques

Use pound cake– Because it is firm, making it easy to cut and carve into the correct shapes without crumbs ending up everywhere.

Don’t decorate warm cakes- Because the heat will cause the icing to melt and become sticky.

Use gel colors for tinting buttercream– Because they are thicker and more concentrated that liquid food coloring and won’t affect the consistency of the icing.

Buy black icing- It takes quite a few days for this color to develop into a deep black shade. Buying it is convenient and a time-saver.

Practice first- Before you start piping on the cake, practice on a sheet of wax paper or parchment paper first because this will allow you to get used to holding the piping bag and figure out how much pressure to apply. It allows you to get the hang of piping.

Room temperature- Once the cake is ready, store it at room temperature away from humidity, moisture, sunlight for up to 24 hours as long as there are no perishable fillings.

Refrigerate- Leftovers can be stored in a sealed container in the fridge for up to 3 days.  Decorated cake also can be stored in a cake box for 2-3 days.

Freeze- Unfrosted cakes and frostings can be stored separately in a sealed containers for up to 1 month. When you are ready to enjoy this dessert, let them thaw in the fridge overnight and then, decorate as per instructions below.
