Here is how the cake shaped up.
Step 1 : Bake your chocolate cake, let it cool in the pan and remove it from your pan after 10 mins. The cake may not be completely cooled when it is removed from your pan. Thats alright, you just don't want the cake to stick to the pan. After your cake is completely cooled, tort your cake. If you want to take it up another step, add a filling inside. Generally, caramel filling really adds dimension to the taste of a chocolate cake. If you don't plan to add a filling, thats alright too. Instead, add a few spoons of sugar water (4 tbsp of water : 1/2 tsp powdered sugar) to keep the cake inside moist.
Step 2: Ice your cake. The best part about this cake is that, your icing doesn't have to be perfect (not even close to how it looks in the picture above).
Step 3: Place kit-kat bars around the cake such that it appears like a barrel.
Step 4: To keep the kit-kat bars in place and also to add a dash of color to your cake, bow them together with a ribbon of your choice. You can also use fondant strips instead of ribbons. I also added brown sugar around the cake board to give a sandy look. Go ahead, get more creative!
Step 5: Once you are here, just add in your piglets. I had hand-made these piglets a day prior. Once you place them in the chocolate pool, twist and turn them so that a puddle effect is created around them. You got your "Pigs in a puddle cake", Oink !
