Bake the chocolate cakes and vanilla cake and allow them to cool completely.
Prepare frosting and color them with gel colors. I recommend buying red and black frosting because it is time-consuming to develop those colors at home.
Place a chocolate cake on a serving dish.
Use a spatula to spread white icing on the outer edges, leaving the center empty.
Cut out a circle from the middle of the vanilla cake to make it hollow.
Place this hollow cake on top of the chocolate cake.
Press gently to secure it properly.
Fill the hollow center with small Pokemon toys and sprinkles.
Use a spatula to spread white icing on the outer edges of the vanilla cake.
Place the other chocolate cake on top.
Press gently to secure it properly.
Ice the side of the cake in white icing. You can ice the top too but I decided to skip frosting the top.
Cover the sides with sprinkles.
Use a toothpick to create a rough template on top of the cake.
Place a circle cutter in the center.
Leave a thin (about 2 inch wide) panel in the center empty without icing.
Fill a piping bag with red icing and attach a small star tip (Wilton's tip # 21). Pipe red stars on the top half of the cake.
Fill a piping bag with white icing and and attach a small star tip (Wilton's tip # 21). Pipe white stars on the top half of the cake.
Remove the circle cutter.
Fill a piping bag with black icing and and attach a small star tip (Wilton's tip # 21). Pipe black stars on the panel, leaving a small circular space in the middle empty.
Fill the empty space by piping white stars.
Stick a small Pikachu character on top of the cake, if you like and enjoy!
