Hawaiian Macadamia Coconut Squares

These bars borrow the bones of a classic pecan pie bar and trade the cast for the Pacific: toasted macadamia nuts and flaked coconut instead of pecans, with a brown-sugar-coffee shortbread base that hits like a buttery espresso cookie.

The instant coffee in the crust is the move here. It deepens the brown sugar without making the bars actually taste like coffee, the same way cocoa works in a chocolate cake. Don’t skip it.

Bake the shortbread on its own first, just twenty minutes until set but still pale. Cool slightly, then pour the coconut-macadamia custard topping over and bake again. The double-bake is what keeps the bottom layer crisp and the top chewy instead of mushy all the way through.

Toasted macadamias are mandatory. Raw ones taste flat and waxy; five minutes in a dry pan or 350°F (175°C) oven brings out the buttery, almost-vanilla flavor that makes this island bar work.

Pro Tips

• Loosen the edges with a knife while the bars are still warm; they release cleanly that way and won’t tear once cooled
• Cut the cooled slab with a long sharp knife wiped between slices for clean squares
• These freeze for up to two months wrapped tight; thaw at room temperature for 15 minutes before serving
• A sheet of parchment with overhang in the pan lets you lift the whole slab out for easier cutting

Variations

• Use sweetened flaked coconut for chewier bars or unsweetened shredded for less candy-bar sweetness
• Swap macadamias for pecans, cashews, or a mix of toasted nuts
• Drizzle the cooled bars with melted white chocolate for an even more tropical finish
