Hello Kitty Birthday Cake Decorating Idea

Hello Kitty fans would love this Hello Kitty birthday cake.

I made this for 2-year-old Lisa whose birthday theme was Hello Kitty. The mother requested for the cake to be in white and pink and so I made little Lisa a 2 tier birthday cake, all in white and pink (with occasional black that is part of Hello Kitty features).

Hello Kitty Birthday Cake

This was a pretty birthday cake and I truly enjoyed decorating it. I also thought it would be good to do a step by step tutorial on how to decorate this cake, so you will find as you read along, detailed step by step images on how I decorated this Hello Kitty birthday cake.

How to Make a Hello Kitty Birthday Cake

Main supplies for the birthday cake:

Raw Materials

Cake – this was a 2 tier cake measuring 6 inches and 9 inches in diameter. Each tier was 6 inches high, so that made the total cake height to be 12 inches. I used my butter pound cake recipe to bake the cakes.
Buttercream – I used buttercream to fill all the cake tiers as well as to crumb coat them.
Fondant – the entire cake was covered in fondant. I used Satin Ice in white, pink and black .
CMC powder – I added CMC powder to the Hello Kitty topper on the cake as well the number 2 topper on the cake. CMC helps the 3D fondant work to dry harder and firmer and therefore hold their shapes better.
Shortening – I used shortening as the glue to stick fondant cut-outs on the cake.
Fondant glue – I used this to stick the Hello Kitty topper and number ‘2’ topper on the cake.

Tools

Hello Kitty cutters – I used 2 different Hello Kitty cutters in this project. The first one was slightly larger and had Hello Kitty image up to its chest. The second one was just Hello Kitty’s face. I used the larger one for the cake topper while the smaller one for the 2D Hello Kitty faces for the sides of the top tier cake. Both these set had tools to emboss the facial features of Hello Kitty.
Scallop paper template – I drew this template by hand to guide me in attaching the pink vertical strips as well as the white scallops all around the bottom tier of the cake.
Pizza cutting wheel
Clikstix alphabet cutter – this was for the birthday girl’s name.
Number ‘2’ cutter.
Plaque cutter – I used this for the pink name plaque.
Extruder tool – I used 2 different disc patterns for this project. One is a small plain round disc for the name plaque border. The other is a 3 combined holes disc for the rope borders of the cake.
Teardrop plunger cutter and round plunger cutter – these were used to make Hello Kitty’s bows on the cake.

Assembling the Hello Kitty birthday cake:

The cakes

Since there were no major fondant deco on the cake that needed to be prepared in advance, I started the entire cake decorating processing by baking the cakes.
Once the cakes have cooled down, I leveled and filled them with buttercream. And then I crumb coated them with buttercream before covering them with white fondant.

Hello Kitty and Number Topper

Next, I made the Hello Kitty topper and the number ‘2’ topper. I added some CMC to white fondant, kneaded it well and then rolled it to about 1cm thickness. I used my larger Hello Kitty cutter for the topper.

And then, while the fondant was still inside the cutter, I used the embossing part of the cutter to imprint Kitty’s facial features and bow on the fondant. And then I removed both the cutter and embossing tool. This was how it looked like.

Next, I added all the facial features. To do this, I used black fondant, rolled them into tiny black oval balls and attached them to the face. For the whiskers, I rolled some black fondant into really thin ropes and attached them to the sides for whiskers.

And finally, for the bow, I used my teardrop and round plunger cutters to make 2 teardrops and one small circle of fondant and attached them on Kitty as its bow. Once that was done, I left Kitty aside to firm up.

As for the number topper, again, I added a little CMC to pink fondant and cut the number out with my number ‘2’ cutter. This too was left aside to firm up while I worked on the rest of the cake decoration.

The pink stripes on the birthday cake

Next was the bottom tier of the cake.
To ensure I had the strips and scallops consistently spaced out all around the cake, I started by measuring the diameter of the cake. Once I had the diameter, I divided it into equal sections. I marked the sections on the paper and used my round cutter to draw a semi-circle, making sure the circle was exactly on the intervals I marked earlier. I then cut out the scallops and used them as my templates.
To guide with the vertical strips, I attached my paper templates all around the cake with shortening. And then I attached the pink stripes to the cake. To make sure the stripes were perfectly straight, I used a ruler to push them to straight lines.

And then, using the round cutter that I used to draw my paper templates earlier, I cut the top of each pink strip to a pointed end.

The white scallops

Next were the white scallops. To ensure the scallops were all same length and height on the cake, I used my paper template again as a guide. That way I was able to get perfectly consistent scallops all around the cake. Once the scallops were all done, I slowly removed my paper templates away.

The pink bows

Next to go on the bottom tier of the birthday cake were the Hello Kitty bows. I made them in the same way, I did for the Kitty topper and attached them all around the cake.

The birthday girl’s name

For the top tier, I started by put the birthday girl’s name on first. I cut out the letters in white fondant and attached them to a pink fondant plaque with shortening. I attached the plaque to the front side of the cake and then added a border to it in the same pink fondant.
The border was piped using my extruder tool and attached to the sides for the plaque with shortening. I have prepared a separate tutorial on how to get your wordings on your cake well centered and you can read all about it here.

Back to the cake. Once the lettering was done, I attached Hello Kitty’s faces all around the cake. I cut using these using my smaller Hello Kitty cutter and attached them to the cake with shortening.

The birthday cake borders

Next, I piped out long strips of pink fondant ropes using my extruder tool, twisted it to make it look like a rope and attached it around the base of both tiers as the cake border.

And finally, I added both the Hello Kitty and the number ‘2’ on the birthday cake with the help of some fondant glue.

With that, the Hello Kitty birthday cake was complete.
