# How to Make It:
01 - Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper, allowing excess paper to overhang for easy removal.
02 - In a medium saucepan, melt butter over low heat. Remove from heat and stir in sugar, eggs, and vanilla extract until the mixture is smooth.
03 - Add cocoa powder, flour, salt, and baking powder to the wet mixture. Mix until just combined, being careful not to overmix.
04 - Pour brownie batter into the prepared pan and smooth the top surface with a spatula.
05 - Bake for 25 to 30 minutes, or until a toothpick inserted into the center emerges with a few moist crumbs. Avoid overbaking.
06 - Allow brownies to cool completely in the pan on a wire rack.
07 - In a bowl, beat together powdered sugar, softened butter, milk, and vanilla extract until smooth. Add green food coloring a few drops at a time until the desired shade is achieved.
08 - Lift cooled brownies from the pan and use a shamrock-shaped cookie cutter to cut individual shamrock-shaped pieces.
09 - Spread green icing over each shamrock brownie. Top with green sprinkles or sanding sugar if desired.
10 - Allow icing to set completely before serving.
