I am taking orders for these so i wont be able to give you the exact recipe but what i will do is give you the method and since i have soo many recipes of cakes and cupcakes on my page you can make them acording to those.
Make a cupcake batter and divide it into portions and color each portion with color of your choice. I used red, green, blue and yellow. Place a spoonful of each colored batter into your cupcake mould carefully. Place in the oven and bake at 180 degrees till done. Should take around 10-15 minutes.
take cream and whip it till its nice and frothy and stiff and then add sugar to taste and whip it a bit more. Remember to whip cream sucessfully you need to chill the cream 1st. You can also use ready made bought whipped cream. Take some cream cheese and leave it out of the fridge to get into room temperature. Mix it well with some vanilla essence and some food colouring of your choice. I used a red color and put just a teeny weeny bit to get this pale orange color. Then mix it with the whipped cream and put it into a piping bag and pipe it onto the cooled cupcakes!!!
