  • For the Brownies
  • 1/2 cup (115 g) unsalted butter
  • 1 cup (200 g) granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup (40 g) unsweetened cocoa powder
  • 1/2 cup (65 g) all-purpose flour
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder
  • For the Green Icing
  • 1 1/2 cups (180 g) powdered sugar
  • 2 tablespoons unsalted butter, softened
  • 2 tablespoons milk
  • 1/2 teaspoon vanilla extract
  • Green food coloring, as needed
  • For Decoration
  • Green sprinkles or sanding sugar (optional)

Instructions

1. Preheat the oven to 350°F (175°C). Line an 8x8-inch (20x20 cm) baking pan with parchment paper, leaving an overhang for easy removal.
2. In a medium saucepan, melt the butter over low heat. Remove from heat and stir in the sugar, eggs, and vanilla until smooth.
3. Add the cocoa powder, flour, salt, and baking powder. Mix until just combined—do not overmix.
4. Pour the batter into the prepared pan. Smooth the top.
5. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Do not overbake.
6. Let the brownies cool completely in the pan on a wire rack.
7. While brownies cool, prepare the icing: 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 desired shade is reached.
8. Lift the cooled brownies from the pan. Using a shamrock-shaped cookie cutter, cut out shamrock brownies.
9. Spread green icing over each shamrock brownie. Decorate with green sprinkles or sanding sugar if desired.
10. Allow icing to set before serving.

Zusatztipps für die Zubereitung

Ensure the butter is completely melted before combining with sugar and eggs to achieve a smooth batter. Avoid overmixing when adding dry ingredients to keep brownies fudgy. Letting the brownies cool fully before cutting prevents crumbling and allows cleaner shamrock shapes.
