4ounces(113g)bittersweet chocolate, a heaping 1/2 cup
½cup(60g)coarsely chopped dry roasted macadamia nuts (see note)
1cup(170g)chopped bittersweet chocolate or chocolate chips
½cuphalf and half or cream
½cup(60g)coarsely chopped macadamia nuts
Preheat the oven to 350 degrees F. Lightly grease a 9X13-inch baking pan (I've only tested this recipe with a metal pan; you might want to decrease the oven temp to 325 if using glass). Set aside.
In a medium saucepan or in a microwave-safe bowl, combine the butter, sugar, and 4 ounces chocolate. Melt over low heat (or microwave) until smooth, stirring often; don't let the mixture overheat. Let cool for a bit (lukewarm is fine, hot is not).
Whisk in the eggs, salt and vanilla.
Stir in the flour and macadamia nuts together until just combined.
Spread the batter evenly in the pan. Bake for 20-25 minutes until set and a toothpick comes out clean or with a few moist crumbs (add time as necessary if they take longer to bake).
Remove the pan from the oven and let the brownies cool completely.
For the fudge topping, combine the 6 ounces chocolate and half and half (or cream) in a small saucepan or microwave-safe bowl. Heat over low heat, stirring constantly, until melted, smooth, and glossy.
Set aside for the topping to cool completely, stirring often if you want to speed up the process and avoid a skin forming on the surface.
When cool but still spreadable, use an offset spatula or knife to spread the topping evenly over the cooled brownies.
Sprinkle macadamia nuts on top.
Chill until ready to serve.
Macadamia Nuts: I have a hard time finding unsalted, dry roasted macadamia nuts unless I seek out specialty markets or online shopping. I've found that I really like the flavor of the lightly salted dry roasted macadamia nuts in this recipe. Try to find "lightly salted" so the salt flavor isn't too strong.Chocolate: I prefer bittersweet chocolate in this recipe but you could substitute semisweet, I am sure if you don't mind a slightly sweeter brownie (milk chocolate will be too sweet, I think).
