Add a spark to your Jojo Siwa party with this recipe for a Sparkle Cake

There isn’t a complete party without a special cake. In this post I want to write about the Sparkle Cake which is a great addition to a birthday party with a theme like Jojo Siwa. It is a multilayered cake with colorful sprinkles on it to give it a special spark – just what a Jojo Siwa party deserves.

Sparkle Cake

It looks pretty delicious in its raw cake form, but covered in sprinkles, it's like a work of art! If you decide to put a bow on it, you got yourself a top-notch eye-catcher at the party!

Surely the little guests at your kid’s birthday will be impressed by it.

Baking the layers

Now you might be thinking to yourself, "The cake looks so good, but it's probably way too hard for me to make that". Well, there is good news for you. It is not! Let’s begin!

Step 1: Preheat oven to 180C (360F) / 160C (320 F) fan-forced. Grease 3 x 6 cm (1.2 x – 2.4 in.) -deep, 20 cm (7,8 in.) base round cake pans. Line bases with baking paper.

Step 2: Place eggs and caster sugar in a large bowl. Using an electric mixer, beat for 8 to 10 minutes or until thick and creamy.

Step 3: Sift flours together 3 times. Add to egg mixture. Gently fold to combine. Gently fold in sprinkles and 100’s and 1000’s. Divide mixture evenly among prepared pans. Bake for 20 to 22 minutes or until sponges spring back when touched. Line 3 wire racks with baking paper. Turn sponges out onto wire racks to cool.

Step 4: Make Mascarpone Frosting. Using an electric mixer, beat mascarpone, icing sugar and vanilla until just smooth. Add cream. Beat until soft peaks form (do not over-beat).

Cake Frosting

Bake as indicated on the package directions to make four layers. Once they're done, set aside the cake with the nicest top - this will be your top layer.

You will have to make sure the rest of the layers are flat and all the same shape. With a large serrated knife, slowly cut along the tops of the other layers until you've created an even surface. This will allow you to stack each layer without it being off-balance.

To begin building your cake, place the bottom layer on a cardboard circle that is smaller than the actual cake. You'll be using the cardboard to help hold and roll the cake in the sprinkles. If you don't have cake circles just take a piece of cardboard, trace around your cake, and cut your own circle. Simple and accomplishes the goal!

Spread a layer of icing between each layer of cake, stacking the layers on top of each other. Now place the layer you set aside at the beginning on top. Once you have four (or how many you decide) stacked layers, you can even out the edges by taking your knife and cutting around the cake until it’s a smooth cylinder.

Sprinkling Process

Now comes the fun part of “sprinkling” your cake and make it spark.

Step 1:  Frost the sides of the cake with a reasonably thick layer of icing.  Bring the icing over the top edge into the center of the cake and remove excess. We are not looking to frost the top of the cake at this stage.

Step 2: Using the cake lifter, lift the cake off the turntable and chill in the freezer for 15 minutes.

Step 3: While waiting for the cake to chill, pour the rainbow sprinkles into a large shallow tray.

Step 4: Using the cake lifter, lift the cake and gently lay on its side in the tray sprinkles. Supporting the cake with your hands on either side (with the help of the cardboard circle on top), roll until you have an even layer of sprinkles adhered to the butter cream.

Step 5: Place the cake back on the turntable. Spoon a generous amount of butter cream on top of the cake. Smooth evenly with the angled spatula, removing any excess. Chill in the freezer for 5 minutes.

Step 6: Place a small bowl upside-down in the center of the sprinkle tray. Remove cake from freezer and place on top of the bowl, being careful to balance the cake correctly.

Step 7: Spoon a large amount of sprinkles on top of the cake and smooth around to edges using the angled spatula, pressing gently as you go to make sure they adhere to the butter cream. Neaten up any missed areas around the edge using the spoon and spatula as shown.

Admire your finished cake for your Jojo Siwa party! This fun cake is sure to brighten up any day.

There are variations and you can certainly put a personal spin on it with some experiments. Some of the ideas we can offer, you can see in the pictures below. One - you can put a bow on it to give it an elegant effect plus it matches perfectly the Jojo Siwa theme party. Second - you can build more tiers and make them different – in different styles or colors. Furthermore you can combine these two ideas.
