Chocolate Thai Green Curry Cake

Name: Chocolate Thai Green Curry Cake
Ingredients: 1 tablespoon unsalted butter; 1 tablespoon cocoa powder; 1 1/3 cup all-purpose flour; 1 teaspoon baking soda; 1/4 teaspoon baking powder; 1/4 teaspoon salt; 3/4 cups whole milk; 1/2 cup good quality cocoa powder; 1/4 cup coconut milk; 4 ounces (1 stick) butter; 1/2 cup turbinado sugar; 1/2 cup granulated sugar; 2 large eggs; 1 teaspoon grated ginger; 1/2 teaspoon vanilla; 1/4 cup granulated sugar; 1/4 cup water; 1 piece ginger, peeled and cut into 1/8 thick slices; 2 small Thai bird chiles; 4 Kaffir lime leaves; 6 ounces heavy cream; 6 ounces 70% dark chocolate; 5 large egg whites; 1 cup granulated sugar; 10 ounces unsalted butter, slightly cooler than room temperature; 3/4 teaspoons green curry paste (I use Maesri brand, as it's really flavorful and doesn't contain shrimp paste. I don't recommend the Taste of Thai green curry paste - it's really bland); 1/2 cup unsalted roasted peanuts; 2 tablespoons coconut milk powder (available at Thai grocery stores and probably on Amazon - what don't they sell?)
