Frosting and Decoration

Instructions

Baking the cake

  • Preheat oven to 170 °Celsius.
  • Beat butter and sugar till soft and creamy for about 2 minutes. Add eggs, one at a time, beating well after each addition.
  • In a separate bowl, sift flour, baking powder, and salt. Fold in the sifted ingredients into the creamed mixture alternately with milk, starting and ending with flour.
  • Finally, add in vanilla extract and combine well. Pour batter into 2 a well greased and floured 9 inches square cake pans and bake for 45 to 50 minutes until the top of the cakes spring back when lightly pressed. The cakes are done when a skewer inserted in the center of the cakes comes out without any wet batter.
  • Remove the cakes from oven and let them cool completely before icing and decorating.

Preparing the cake

  • Once the cake layers are baked and have cooled completely, level the tops and fill the layers with buttercream. And then crumb coat with a thin layer of buttercream. The crumb coat is to make sure the top and sides of the cake are all level and flat.

Buttercream sea effect on the cake

  • Next, tint the butter icing in blue with Wilton Royal Blue food color. Since the icing has a natural yellow hue to it, adding blue to it will turn it into a blue with a slight hint of green. That sea blue color is perfect for this cake as the blue cake covering is meant to represent the seawater.
  • Apply the icing all over the cake and then, instead of smoothing it flat, press it down with your fingers. The dents are meant to represent sea waves.
  • Once the entire cake is covered in butter icing sea waves, make the border. Use blue fondant for the border and the waves cutter to make a layer of waves and attach them all around the base of the cake.
  • The butter icing will be able to hold the fondant strips in place without the need for any additional fondant glue.

The lettering on the cake

  • Roll some pink fondant thin and cut the letters out with alphabet cutters. Place them on the cake.
  • Once the letters are in place, make the rest of the decoration to match the Little Mermaid theme.
  • Start by adding the long sea grass on the corners of the cake. To make the grass, roll some dark green fondant and use a pizza cutting wheel to cut the grass blades. You can do this freehand. Mark the lines on the grass with a sugar craft needle scriber tool before attaching to the cake.

The pink corals

  • Shape the pink corals by hand with pink fondant. Use a thin wooden skewer to poke holes all over the coral.
  • And then attach them to the sides of the cake. You do not need any special glue to stick the corals to the cake, the butter icing will be able to hold the decoration well in place.

Edible sea creatures in fondant

  • For the brown and yellow fondant sponges, roll some brown and yellow fondant thin, and use the round plunger cutters to make random holes in random order all over the rolled pieces. Place the sponges on the sides of the cake (brown sponge) as well as the top (yellow sponge) of the Little Mermaid cake.
  • Next is the cluster of purple cylinder-shaped sea plants. Make these individually by rolling some purple fondant into sausages. Using the pointed end of the shaping tool ( the one that is shaped like a pencil), make holes on one end of the sausages. Group a few of them together and attach them to the cake.
  • When grouping these together, dampen them slightly with a damp brush so that they would stick to one another. And in attaching the clusters to the cake, again, the icing is sufficient to hold them in place. Make a few clusters of these and add them to the sides of the cake.

DIY fondant fish

  • Make the yellow fishes by hand. Simply form them with some yellow fondant and enhance the shape with fondant tools. Add the blue strips and black eyes to complete the fishes before attaching them to the cake.

The fondant starfishes

  • Roll some brown fondant thin and cut out the starfishes using a 5 petal daisy flower cutter. To make the white dots, dip a fine tipped cake decorating brush into undiluted white gel based food color and mark the dots on the starfishes.
  • Let the paint dry and place the completed starfishes randomly on the sides and top of the butter icing covered cake.
  • Once all the cake decoration is done, arrange the Disney themed toy toppers on the cake. For the figurines on the cake board, you can use hot glue to hold them in place. The ones on the cake can be simply placed on the cake if they have wide bottom bases. They should be able to stand on the cake well.
  • Add more decoration on the sides of the Little Mermaid themed figurines on the cake just so that everything looks as naturally placed as possible.
