Instructions
Preheat oven to 350°F. Line 8x8-inch baking pan with parchment paper.
In a small saucepan, heat butter until the butter melts. Add milk and coffee and continue heating until milk barely starts to bubble around the edges. DO NOT allow it to come to a boil. Remove the pan from the heat.
Sprinkle cocoa powder over warm butter/milk/coffee mixture in the pan and set aside to allow cocoa to bloom for 10-15 minutes.
In a mixing bowl, lightly whisk together 1 cup granulated sugar, 2 eggs, and 2 teaspoons vanilla until combined. Add 1 tablespoon vanilla extract, melted butter/milk and coffee/cocoa mixtures to sugar and eggs.
Sift together 1 cup mochiko, 1 teaspoon baking powder, ¼ teaspoon salt directly over the bowl with the liquid ingredients. Stir until well combined. Fold in chopped chocolate if using.
Pour brownie batter into pan and tap lightly against countertop to pop any large air bubbles.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Immediately sprinkle with flaky sea salt if using.
Let brownies cool in pan for 10 minutes, then lift out of pan using the parchment paper as handles. Cool completely on wire rack. To cut, use a disposable plastic knife for the cleanest cuts.
