准备

• Position a rack in the center of the oven and heat the oven to 325ºF. Line the bottom and sides of a 9×13-inch baking pan with foil, leaving some overhang on the sides, and spray with cooking spray.

Make the brownie layer:

• In a medium saucepan over medium heat, whisk the butter until it is melted. Remove the pan from the heat and add the sugar, cocoa powder, and salt. Whisk until well blended, about 1 minute. Add the eggs and vanilla and whisk until smooth. Add the flour and stir with a rubber spatula until blended. Scrape into the prepared pan and spread evenly. Bake until the top is shiny and dry-looking and the brownie springs back very slightly when pressed with a fingertip, about 20 minutes. (The brownie should not be completely baked.) Remove from the oven and put on a rack.

布朗尼层烘烤时，将澳洲坚果浇灌：

• 在一个大的搅拌碗中，将红糖和面粉混合在一起。搅拌直至充分混合，分解任何大团块。加入玉米糖浆，融化的黄油和香草。搅拌直至混合，约1分钟。加入鸡蛋，然后搅拌直至混合，约30秒。（不要过度混合或面糊会是泡沫状的。）加入坚果和椰子，然后用橡皮刮刀搅拌直至均匀混合。
• Pour the macadamia topping over the warm, partially baked brownie layer. Using a spatula, carefully spread the mixture into an even layer. Return the pan to the oven and bake until the top is golden brown, 37 to 40 minutes. Transfer the pan to a rack to cool completely.
• Using the foil as handles, lift the rectangle from the pan and invert onto a work surface. Carefully peel away the foil. Flip right side up. Using a sharp knife, cut into 2×2-inch squares and then cut each square into triangles.

提前提示

After the brownie and macadamia layers have been baked and cooled, the entire pan can be wrapped in plastic wrap, then foil, and frozen for up to 1 month.
