In a medium bowl, combine light brown sugar, matcha powder, ground cinnamon, and a pinch of fine salt. Whisk to ensure even distribution.

In a large bowl, sift together all-purpose flour, matcha powder, instant dry yeast, and fine salt. Mix thoroughly.

In a microwave-safe bowl, combine whole milk, unsalted butter, and granulated sugar. Heat until butter melts. Pour mixture into flour mixture.

Add eggs one at a time, stirring well until a sticky dough forms. Gradually add more flour if needed and knead until smooth.

Transfer to a greased bowl, cover, and let rise in a warm place for 10-20 minutes.

Roll out dough into a rectangle. Spread softened butter and sprinkle prepared filling on top.

Roll tightly from one edge and slice into 12 equal pieces using dental floss.

Place rolls in a greased baking pan and cover. Let proof for 30 minutes.

Preheat oven to 350°F (175°C). Bake rolls for 28-32 minutes until golden brown.

In the meantime, prepare frosting by beating together cream cheese, softened butter, vanilla extract, and powdered sugar until smooth.

Once baked, drizzle frosting over the rolls and swirl additional matcha for decoration.
