Zebra cake

Today I help my mom to make zebra cake (brindle cake like zebra). Unfortunately failed. The cake is not perfect, but although the cake still tastes good. The taste of milk from the cake is felt, I like it. Apparantly my mom knows the reason why the cake is not perfect. It's because the material combination is not right. Hahaha... may be next time I and my mom will try again to make zebra cake
