Pink 21st Birthday Cake

🧾Supplies Required

• Cake – Only the bottom tier was cake, measuring 12 inches in diameter. My customer chose coffee-flavored butter cake and so I baked it using my coffee cake recipe.
• Styrofoam dummy – Both the top and second layers of the cake were Styrofoam dummies. 
• Buttercream – I used buttercream to fill the real cake layers as well as to crumb coat the cake.
• Fondant – this was used to cover the whole cake. I used Satin Ice in pink, white, and black. I also used fondant for the stars, the ribbon, and the tiara, however, for these items, I added a bit of CMC so that they set hard and firm.
• Extruder tool – This tool helped me in producing even-sized roll for the tiara, the pink rope border, the white plain border as well as the key.
• Gold dust & lemon extract – I mixed these two to make gold paint and used it for the key and tiara.
• Star cutters – I cut the bursting stars on the cake with these cutters. Each one was attached individually to white floral wires. I also used tiny stars for the back of the cake. These were cut out using star-shaped plunger cutters.
• Heart shaped cutters –  I used 2 different sizes to make the pink bow on the cake.
• Round scalloped cutters – These were used to cut out the black circles on the sides of the 1^st and 3^rd tiers where I attached the number ‘21’ and the gold key respectively.
• Floral wires – the wires held the bursting stars on the cake. I used gauge 18 so that they could hold the weight of the stars and not bend away.
• Alphabet cutters - I used Clikstix cutters for the name on the cake board as well as the number ‘21’.
• Diamond embossing mat– I used this mat to imprint the diamond patterns on the sides of the second tier.
• Fondant glue & shortening

👩‍🍳How to Make

Step 1: Decorate the Dummy Layers

Since the first and second tiers of the 21st birthday cake were dummies, I could decorate them ahead of time. I covered the top dummy with pink. The second one was covered in white. There was no need for a crumb coat when covering dummies. All I had to do was brush them with water and cover them with fondant. Click here to read all about using cake dummies.

I used my diamond embossing mat to imprint diamond shapes all around the tier and attached tiny pink balls (hand-shaped) at equal intervals.  At the back of the cake where the imprint didn’t quite align, I used little pink stars to hide it.

Step 2: Make the Stars and the Tiara

I also made the stars and the tiara for the 21st birthday cake ahead of time. This was so that they could have enough time to dry and set hard. For the stars, I used 2 different sized cutters. I cut them in pink and black (that has been mixed with CMC). I attached one wire into each star and let them set completely, lying flat.

As for the tiara, I used my extruder tool to pipe out a long thin roll of fondant. I used a template for the tiara, drew it on a piece of paper, and glued the paper template to the sides of a 5-inch round cake dummy. And then, I guided the piped strip to follow the design on my template. I used fondant glue to attach all the pieces of the tiara together.

Once done, I left the tiara to set completely (I left mine overnight). And then I slowly removed it from the template, placed it on a cake board before painting it with gold edible paint (gold dust mixed with lemon extract).

Step 3: Make the Gold Fondant Key

I made the gold key for the 21st birthday cake in the same way as the tiara. 

Step 4: Assemble the Pink 21st Birthday Cake

Once the cake was baked, I leveled the layers. And then I sandwiched them and crumb coated the cake with buttercream. And then I covered it with white fondant. Next, I measured the circumference of the cake and drew out a scalloped template. I placed the template on the sides of the cake and marked the scallops using my needle tool.

And then I cut out black strips and attached them to the cake with some shortening.

Once the strips were done, I piped out a long thin fondant roll using my extruder tool and attached it to the cake, following the scallops’ markings I made earlier. To attach the roll, I used shortening.

As for the round black plaque on the first and third tiers, I used my round scalloped cutter and poked tiny holes all around them. I then used my fine-tipped brush to paint dots of white on the holes. For this purpose, I used Americolor liquid food color.

Step 5: Make and Attach the Bow

Next to go on this pink 21st birthday cake was the bow. I used heart-shaped cutters for the loops and attached them to the cake with shortening.

Finally, before placing the stars and the tiara on the cake, I added the border and the wordings on the cake.

And that completes the pink 21st birthday cake.
