I *NEED* the recipe. Please. The photo made my heart race! 
Here you go...I just got the Hummingbird Cake Cookbook from the Bookpeople and I tried this one first. I might do coconut later this week!
Green tea cupcakes
120mL whole milk
3 green tea bags
100 grams plain flour
20 grams cocoa powder
140 grams caster sugar
1 1/2 teaspoons baking powder
a pinch of salt
40 grams unsalted butter (at room temperature)
1 egg
1/4 teaspoon vanilla extractGreen tea frosting:
250grams icing sugar, sifted
80grams unsalted butter (at room temperature)
20 grams matcha green tea powder, plus extra to decorate
25 mL whole milka 12-hole cupcake tray, lined with cupcake cases
Put milk and green tea bags in a jug, cover and refrigerate for a few hours, or overnight if possible.
Preheat oven to 170°C/325°F (Gas 3).
Put the flour, cocoa powder, sugar, baking powder, salt and butter in a bowl and beat on a slow speed with an electric whisk until you get a sandy consistency and everything is combined.
Remove the green tea bags from the infused milk and combine with the egg and vanilla extract. Slowly pour half into the flour mixture, beating well until all the ingredients are well mixed.
Turn the mixer up to high speed and beat well to make sure there are no lumps. Turn the speed back down to medium-low and slowly pour in the remaining milk mixture.
Continue mixing for another couple of minutes until mixture is smooth.
Spoon the mixture into the cases until 2/3 full and bake in the preheated oven for 20-25 minutes, or until sponge bounces back when touched. A skewer inserted in the centre should come out clean. Leave the cupcakes to slightly cool in the tray before removing to wire cooling rack to cool completely.
When cupcakes are cool, spoon the green tea frosting on top.
Green tea frosting:
Beat the icing sugar, butter and matcha powder together with an electric mixer on medium-slow speed until the mixture comes together and is well mixed.
Turn the mixer down to a slower speed. Slowly pour in the milk, then when it is all incorporated, turn the mixer up to high speed.
Continue beating until the frosting is light and fluffy, at least 5 minutes.
Decorate the cupcakes with frosting and light sprinkling of matcha powder.
