Prepare a sheet cake pan for baking - grease and line with parchment paper.In a bowl, combine flour, baking powder, baking soda, and salt - set aside.
In the mixing bowl of a stand mixer, cream butter and sugar until light and fluffy. Add eggs one at a time until well combined. Use a spatula and scrape the sides of the bowl when necessary.
Next, add the flour and milk mixture in three batches. Followed by the vanilla extract.
Vanilla batter - Lift one side of the sheet cake pan by placing a small plate or spoon under one side of the pan. Pour half the batter. It will rest on one side.
Chocolate batter - Add the cocoa and milk mixture to the other half, remove the bowl/spoon from under the pan, and pour the second batter.
Bake in the preheated oven on the middle rack for about 30 to 40 minutes, or until the skewer inserted into the center comes out clean. Cool in the pan for 10 minutes, then invert on a cooling rack and cool completely before you frost it.
SpongeBob
Print a picture of the character (SpongeBob SquarePants) for reference.
Level - cut any dome off the cake with a serrated bread knife. Brush the cake with sugar syrup.
Cut the cake in half, then in half again. This will give you 4 - 3 x 9-inch pieces. Cut each piece to about 6 inches. Stack two pieces with buttercream (see video.
Add three dowels (I use straws), a cake circle/board, and 2.5 x 5-inch pieces. Add the next two layers with frosting in between.
Then, crumb coat with ganache. Chill 15 minutes, then coat with more ganache. Chill for another 15 minutes.
Meanwhile, roll out yellow fondant. Cut strips about 8 x 9 inches for the front and back and 4 x 7 inches for the sides. (don't make them too large to prevent waste).
Lay the fondant on a baking tray lined with parchment paper. Chill the fondant pieces in the fridge for 10 minutes. Then, brush the cake with water and press the cold fondant pieces to SpongeBob. Use a cake smoother to cut off the excess as shown in the video.
Once the cake is paneled and the excess cut off. You can now make holes using a ball tool (if you don't have a ball tool, dip your knuckles in flour and gently press in).
After this, it is time to make the remaining details as shown in the video.
SpongeBob's eyes - White fondant with blue and black.
Brown pants - with a rolling pin, roll a long strip of fondant about 11/2-inches thick. Roll the dough on the work surface like a jelly roll, then unroll it onto the cake as shown in the video. You will also need a thin strip of black for his belt as well.
Shirt - A strip of white above the belt. Don't forget to make his tie and collar.
Hands and Legs - Roll the same yellow fondant into a thin cylinder. Cut and shape as shown in the video.
Shoes - Small balls of black rolled into a ball, then shaped into a shoe as shown in the video
Nose - You will need a small piece of yellow fondant rolled into a cylinder about 5 inches long - Use a cocktail stick to attach it to the cake.
Small details - Mouth, teeth, tongue, outline for the eyes, eyebrows, etc.
Patrick Star
Print the picture of the character to use as a reference.
Bake two dome/ sphere cakes using a ball pan. Cool completely.
Join the two halves with frosting to make a ball. Chill so the frosting holds them together.
Place them on the cake board - cut off a little on the bottom to create a flat base.
Use cake trimmings mixed with frosting (cake pop mixture) to create Patrick's tall head (see video).
Roll the fondant and cover the cake as shown in the video. Cut off excess, then use your hands to rub gently and seam the edges.
Now, make the rest of the details as shown in the video.
Pants - Lime green fondant with purple flowers. As shown in the video, roll the two sides in and then unroll onto the cake.
Eyes - White fondant in oval shapes with black circles.
Hand and legs - Patrick's hands are the same color as his body, rolled into a cylinder and then tapered towards the end.
Mouth - A black strip for the mouth.
Sand and Shells
Sand - I used cookie crumbs and brown sugar, pulsed in the food processor for the sand.
Shells - The shells are melted white chocolate in shell molds.
