The Ultimate Fudgy Mochi Brownies Recipe Perfect Chew

Instructions:

1. Preheat oven to 350°F (175°C). Line an 8x8 inch (20x20 cm) metal baking pan with parchment paper, ensuring an overhang on two sides for easy removal.
2. Gently melt the butter and chopped dark chocolate together using a double boiler or in short bursts in the microwave until completely smooth. Let the mixture cool slightly for about 5 minutes.
3. Whisk the granulated and brown sugars into the slightly cooled chocolate mixture until just combined.
4. Whisk in the eggs and the extra yolk one at a time. Mix vigorously for a full minute after each addition until the batter lightens slightly and becomes glossy. Stir in the vanilla extract.
5. In a separate bowl, use a fine-mesh sieve to sift together the glutinous rice flour, cocoa powder, all-purpose flour, and salt.
6. Gradually fold the dry ingredients into the wet mixture using a rubber spatula. Mix only until the streaks of flour disappear. Over-mixing will ruin the signature chew of the mochi.
7. Gently fold in the optional chocolate chips. Scrape the sticky batter into the prepared pan, smoothing the top surface. Sprinkle generously with flaky sea salt, if using.
8. Bake for 30–35 minutes. The edges should appear set, and a toothpick inserted near the center should come out with moist, fudgy crumbs clinging to it—not wet batter, but definitely not clean.
9. This step is vital: Allow the brownies to cool completely in the pan on a wire rack (at least 2 hours) before attempting to lift or cut them. Cooling allows the unique mochi starch structure to set properly.
