- 1/4 teaspoon salt
- 1/4 teaspoon baking powder

How to Make St. Patrick’s Day Brownies
Whip up these incredibly fudgy St. Patrick’s Day Brownies in under an hour. Their rich chocolate flavor is enhanced by festive green swirls and pops of color, making them a crowd-pleaser for all ages. With a prep time of just 15 minutes and a bake time of 25-30 minutes, you’ll be enjoying these delightful treats in no time, perfect for a spontaneous St. Paddy’s Day celebration.
Step-by-Step Instructions
- Preheat your oven and prepare your pan: Preheat your oven to 350°F (175°C). Grease and flour an 8×8 inch baking pan, or line it with parchment paper, leaving an overhang on the sides to easily lift the brownies out later. This step ensures your brownies bake evenly and don’t stick.
- Combine wet ingredients: In a medium bowl, whisk together the melted butter and granulated sugar until well combined and slightly lighter in color.
- Incorporate eggs and vanilla: Add the two large eggs, one at a time, beating well after each addition. Stir in the vanilla extract until everything is incorporated into a smooth mixture.
- Add dry ingredients: In a separate small bowl, whisk together the all-purpose flour, unsweetened cocoa powder, salt, and baking powder. This ensures all the dry ingredients are evenly distributed.
- Gently fold in dry ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can lead to tough brownies. A few streaks of flour are okay at this stage.
- Prepare the green swirls: In a small microwave-safe bowl, melt the green candy melts according to package directions (usually in 30-second intervals, stirring in between). If using white chocolate chips for contrast, melt those separately as well.
- Assemble the batter: Pour about two-thirds of the brownie batter into your prepared baking pan and spread it evenly.
- Create the green layer: Drizzle the melted green candy melts over the brownie batter in the pan. If using, drizzle the white chocolate chips over the green as well.
- Add remaining batter and swirl: Dollop the remaining one-third of the brownie batter over the green chocolate layer. Use a knife or a toothpick to gently swirl all the layers together, creating a marbled effect. Be creative with your swirls, but avoid over-swirling, which can mix the colors too much.
- Bake the brownies: Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs, not wet batter. The edges should be set.
- Cool and decorate: Let the brownies cool completely in the pan on a wire rack. Once cooled, you can lift them out using the parchment paper overhang. Cut them into squares. If desired, decorate with green sprinkles, shamrock candies, or edible glitter for an extra festive touch.

Storing and Reheating Tips

If you wish to freeze them, wrap individual squares tightly in plastic wrap, then place them in a freezer-safe bag or container. They can be frozen for up to 3 months. To reheat gently warmed brownies, place them on a microwave-safe plate and heat in 10-15 second intervals until just warmed through. For frozen brownies, thaw them at room temperature for a few hours or gently warm them.
