Preheat oven to 175°C. Line a 20x20 cm baking pan with parchment paper, allowing overhang for removal.

In a medium bowl, whisk sweet rice flour, sugar, matcha powder, ground pistachios, and salt. Add milk, melted butter, and vanilla extract; whisk until smooth. Pour into a lightly greased, microwave-safe dish. Microwave on high for 2 minutes, stir, then continue for 1–2 more minutes until thick and sticky. Alternatively, steam over simmering water for 12–15 minutes, stirring occasionally. Set aside to cool slightly.

Place butter and chopped chocolate in a heatproof bowl over gently simmering water. Stir until fully melted and smooth. Remove from heat.

Whisk granulated sugar into the chocolate-butter mixture. Beat in eggs one at a time until glossy, then stir in vanilla extract.

Sift in all-purpose flour and salt. Mix gently until just combined, then fold in coarsely chopped pistachios.

Spread half of the brownie batter evenly into the prepared pan.

With lightly oiled hands, flatten cooled mochi into a square slightly smaller than the pan. Place mochi sheet over the brownie base.
08 -
Gently spread the remaining brownie batter over the mochi, covering completely and evenly.
09 -
Bake for 30–35 minutes, or until the top is set and a toothpick inserted at the edge comes out with a few moist crumbs. The center remains chewy due to the mochi.

Allow to cool completely in the pan. Lift out using parchment, slice into squares, and serve.
