Purple sweet potato and Green tea Pound cake

Today, our cake has two colors.

The green part of the cake is green tea, and the purple part is purple sweet potato (using purple sweet potato powder).

The reason for making this cake was simple ^^ because I wanted to use the purple sweet potato powder that I keep it for a long time in the freezer, haha. Anyway, I didn't want to make something complicated.

Turning it into a pound cake is the best way (for me) because my family members love to eat this kind of cake very much.

But only sweet potato will make the cake purple, not cute enough, and a bit boring hehe. 

When coming with green tea, the bitterness taste of the green tea goes very well with the sweetness from the sweet potato, and yes, the color is more lovely too.

There are many pound cake recipes, for this one, the main ingredients (egg, butter, sugar, and flour) are almost the same weight. With only a small amount of the baking powder and liquid, the cake comes out very moist and dense. Serve a thin slice of this cake with a cup of hot tea or black coffee is the best for me.
