Nothing says bananas like a monkey. A banana cake is a dessert that can be moulded into the shape of a monkey head for a child's birthday cake. Depending on the recipe, you can add more bananas to enhance the flavour, but don't add more than one or two. The bananas give the cake mildly gelatinous consistency that helps preserve the shape but also make it quite heavy. If you are set on making a twelve-layer cake, a banana cake recipe can be frustrating to stack because of the weight. Fortunately, with a few simple steps you can create a monkey-shaped cake of your own.
Bake a single layer, round banana cake and a separate batch of banana cupcakes from the same batter. Set both baked items in your refrigerator to cool for at least two hours to prevent tearing during cutting.
Remove the top of one cupcake. Cut the remaining cupcake base in half horizontally. Frost in between the layers to create a two layer mini-cake. Join the two halves with frosted sides together. Cut this mini-cake in half vertically and chill the two semicircles in the refrigerator for half an hour, firming the frosting in between the layers.
Frost the top and sides of your 12-inch cake with whatever colour you want for your monkey. The two half-circles you made earlier should continue chilling in the refrigerator during this time.
Remove the two half-circles from the refrigerator and spread icing on the cut sides and top of each half-circle. Adhere one half on each side of the monkey face as the ears, with the frosted cut sides facing the main cake. Place the entire monkey cake in the refrigerator. Cooling the unifying frosting between the ears and the face of the cake makes the attachment between the mini-cake ears and the 12-inch cake more secure.
Remove the monkey cake from the refrigerator after 30 minutes and apply a top layer of frosting with a flat cake server or wide knife to smooth out the creases and bumps. Waiting until after the first layer of frosting is cooled allows a smoother application for the final frosting layer.
Colour enough frosting for the ears and the face to avoid having two different colours.
