The one that i LONG to make... Green tea marble cake..

Ingredients
3 eggs
1 cup sugar
1 1/2 cups plain flour
3/4 teaspoon baking powder
pinch of salt
1/2 cup full fat plain yogurt
2 teaspoons vanilla extract
1/2 cup of melted unsalted butter
2 tablespoons green tea powder (matcha)
1 teaspoon of lukewarm water

Frosting
125g cup butter, softened
225g cream cheese, softened
3 cups icing sugar
2 tablespoons green tea powder (matcha)


Method

Preheat oven to 375°F / 190°C, remembering to subtract 20°C if using a fan-forced oven, and another 10°C if using a non-stick cake pan.

Line a 10cmx21cm standard loaf pan with baking paper or lightly oiled greaseproof paper.

In a large bowl, beat the eggs and sugar together until pale and creamy.

Add the sifted flour, baking powder and salt. Mix until combined.

Add the vanilla and yoghurt and stir until well combined.

Slowly add the melted butter and using an electric mixer, beat until you have a uniform batter.

In a separate bowl, make a thick paste with the matcha powder and warm water. Add a third of the cake batter to the matcha paste and incorporate until the batter is an even green.

Place alternate spoonfuls of green and white batter into the loaf tin until all the batter has been used. This doesn't have to be exact. Using a skewer, make a few gentle swirls through the batter so the colours meld around each other.

Carefully tap the cake tin on the counter a few times to remove any air bubbles. You can also drop the cake tin onto the counter from a height of about 10cm to force out any air bubbles.

Bake cake for about 40 minutes or until a skewer inserted comes out clean.

To make the frosting, beat butter and cream cheese until light and fluffy. Add sifted icing sugar and half the matcha powder and beat until combined. Add more matcha to taste. Spread icing on cooled cake and dust with extra matcha powder for decoration.
