Rainbow pancakes are very simple and very attractive, so you should give them a try
First you will need to make your regular pancake/crepe batter. You can find these online or in a cookbook.
Next you will need 4 mugs.
Divide the batter equally into each if the mugs, and in one, add 3 drops of orange food coloring. In the 2nd, add 3 drops of green. Now 3 drops of blue, then 3 drops of yellow. Use a separate lolly stick to mix the coloring into each one
Now take a frying pan and put it in the stove to heat up. Grease the pan, and pour in the first color. Swirl it round and let it cook. Flip with spatula and cook the other side. Do this until your first color has run out.
Repeat with the 3 remaining colors.
