• Step 1: Preheat your oven to 350°F (180°C). Grease an 8×8-inch baking pan with butter or non-stick cooking spray.
• Step 2: In a large bowl, whisk together the melted butter and sugar until well combined. Beat in the eggs one at a time, then stir in the vanilla extract.
• Step 3: In a separate bowl, sift together the flour, cocoa powder, matcha powder, and salt. Gradually fold the dry ingredients into the wet mixture, just until no dry pockets remain.
• Step 4: Pour the batter into the prepared baking pan, smoothing the top with a spatula.
• Step 5: Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs attached. Be careful not to overbake.
• Step 6: Allow the brownies to cool completely in the pan before cutting into squares and serving.
