Green Tea Ogura Cake

I came cross this Ogura Cake recipe from MiMi Bakery House and would like to attempt using Green Tea powder. The only mistake I did was I used 8 inch square baking pan instead of 7 inch so the cake turned out not as high as I expected. However, the texture was good and the pattern came out pretty. I would like to try with other flavours such as Milo or Coffee as in original recipe.
