I wasn’t always a fan of nuts in brownies. As a child I often encountered brownies where the nuts overwhelmed the chocolate, so I learned to inspect a brownie before taking a bite. Over time I came to prefer brownies that are fudgy and chocolaty on their own, served simply with a glass of milk. For many years I avoided adding nuts to my brownies.
Recently I began experimenting with new brownie variations. I enjoyed the crunchy top of the Caramel Oatmeal Brownies I tried and the playful notes in Peppermint Cookies and Cream Brownies, which nudged me to revisit the idea of nuts. I skipped the usual walnut route and chose toasted pistachios instead. Their vibrant green hue and rich, buttery flavor pair beautifully with chocolate.
This recipe uses a double-chocolate base: melted dark chocolate folded into the batter for depth, and milk chocolate chunks stirred in to add sweetness and complement the pistachios. I used a 60–72% dark chocolate; the dark chocolate gives the brownies an intense, rounded chocolate flavor while the milk chocolate adds soft sweetness. The result is a moist, rich brownie that isn’t overly gooey or cake-like — it almost melts in your mouth. The balance of texture and flavor is excellent, and these have earned a permanent place in my baking rotation despite the addition of nuts.
Store extra brownies in an airtight container in the refrigerator or freezer. They are pleasant chilled, and crumbled cold brownies make a tasty ice cream topping.
Double Chocolate Pistachio Brownies
1/2 cup butter
9 oz dark chocolate, chopped (60–72% cacao)
3/4 cup brown sugar
1 cup all-purpose flour
3 large eggs
2 tsp vanilla extract
1/4 tsp salt
1/2 cup milk chocolate chunks or chips
1/2 cup toasted pistachios
Preheat the oven to 350°F (175°C). Line a 9-inch square baking pan with aluminum foil or parchment and lightly grease the lining.
In a medium heatproof bowl, combine the butter and chopped dark chocolate. Melt gently—either in the microwave in 30-second intervals, stirring between each, or over a double boiler—until smooth. Stir in the brown sugar while the chocolate is still warm so it dissolves slightly.
In a large bowl, whisk together the eggs, flour, vanilla, and salt. Pour the warm chocolate-butter mixture into the egg-flour mixture and whisk until just combined. Fold in the milk chocolate chunks and toasted pistachios.
Pour the batter into the prepared pan and spread it evenly. Bake for about 30 minutes, or until a toothpick inserted near the center comes out with moist crumbs but no wet batter.
Allow the brownies to cool in the pan for about 10 minutes, then lift them out using the foil or parchment and transfer to a wire rack to cool completely. Once cooled, slice into 25 small squares with a sharp knife for neat edges.
