For the pancakes: (for 2 rainbow stacks)
4 eggs
4g baking powder
4g baking soda
Pinch salt
250g flour
50g sugar
50ml oil
120ml buttermilk
2 Lemons (organic)
Food coloring : red, orange , yellow, green, blue, purple
Utensils:  7 small bowls (yes, you read it right, seven), 1 big bowl, whisk, 6 teaspoons, well coated pan, grater, lemon press (optional), handheld mixer

1. Take one small bowl and stir the flour, salt, baking powder and baking soda together and put it aside. Take the grater and pull of the skin of one of the lemons and add it to the flour mixture (make sure the lemon is organic if you are adding zest into the batter). Now you can squeeze the lemon juice of both (for example into a glass).
2. Separate the eggs. The egg white goes into the big bowl and the egg yolk in one of the empty small bowls. Add the sugar to the egg yolk and stir well until it gets a little bit brighter. Then you can add the oil. Put this bowl aside too.
3. Now you should whisk the egg white with the handheld mixer until it is nearly stiff. Add the buttermilk and the lemon juice to it and mix it again.
4. Add the egg yolk mixture into the big bowl. Now you can use the whisk so stir it. Pour the flour mixture from the first bowl in and stir it until everything is combined. Divide the batter into 6 equal parts in the little bowls. You can use the big bowl as the 6th bowl.
5. Add the food coloring to each bowl (red, orange, yellow, green, blue and purple). Use 6 different teaspoons to mix it!
6. Let's cook! Take a well coated pan and preheat it on low heat and use only a little bit of oil: put the oil on a paper towel and wipe the pan with it (this creates a thin oil coat). If the pan is big enough you can make more than one pancake at a time. But only use one colored dough at the time! You can flip the pancakes when you see some bubbles on the top. Don't wait until the pancakes are brown, we are trying to keep the rainbow colors here (that's why the low heat). We used a big cookie cutter to cut the pancakes, so the colors are more visible and vivid, but you can skip this part.

For the topping:
200g powdered sugar
1 Lemon
Utensils:
1 small bowl, a lemon press, sifter

1. Since the topping hardens pretty quick you should make it AFTER you make the pancakes. Squeeze the juice of the lemon in a small bowl. If you don't have a Lemon press you can also use a fork. Stick the fork in the lemon and turn it around and around. Now you need a sifter. Without your frosting will get some crumbles, but if this is OK for you you can also make it without a sifter. Add the powdered sugar to the juice and stir well. So easy and good!
2. Stack the pancakes it the rainbow order (purple, blue, green, yellow, orange and red) and pour the lemon frosting all over it (unless you already ate it)! Happy Birthday to everyone!
