Alice's Little Kitchen: 3-Color Butter Cupcake

Initially, when I wrote this recipe down, I had in mind to make a butter loaf cake. I changed my mind after I have made the banana cupcake. It's easier to make it into cupcake form. Save me some time for cleaning the pan after the baking. Hehe.. Just too lazy I guess. I love to minimize all the workloads...>.<..

3-Color Butter Cupcake (16 cupcakes)
Ingredients:
1 cup butter
130g sugar

4 eggs
230g flour
2 tbsp baking powder
1/2 cup milk
1 tbsp vanilla extract
(a)*1 tbsp cocoa powder, 1 tbsp coffee powder, 5 tbsp hot water
(b)*1/2 tbsp green tea powder, 4 tbsp hot water

Steps:
1. Preheat oven to 360 F. Line cupcake pan with cupcake liners.
2. Cream butter and sugar till creamy and pale in color.
3. Beat eggs one by one to avoid forming lumps.
4. Add sifted flour mixture (flour+baking powder) into batter. Add milk and vanilla extract.
5. Divide the batter to 3 portions. Put aside 1 portion for original taste. Add (a) into the 2nd portion and mix well. Add (b) into 3rd portion.
6. Scoop batter into cupcake liner. First put original batter, then green tea batter, then cocoa batter. (Any combination will do too. You can swirl the batter with toothpick or not, based on own choices, I did both.)
7. Bake in oven for 20-25 minutes or toothpick inserted comes out clean.
8. Cool completely on wire rack.

Very moist cupcake, and you can smell three different smells, not a bad combination! Although I think loaf pan format will be nicer, you can see the color difference more obvious.
