# What You'll Need:
→ Crust and Crumble
01 - 1 cup all-purpose flour
02 - 1 cup old-fashioned rolled oats
03 - 1/2 cup granulated sugar
04 - 1/3 cup packed light brown sugar
05 - 1/2 teaspoon salt
06 - 1/2 teaspoon ground cinnamon
07 - 1/2 cup unsalted butter, melted
08 - 1/2 cup unsweetened shredded coconut
09 - 1/2 cup roasted macadamia nuts, roughly chopped
→ Filling
10 - 1 cup guava jam or guava paste, softened
11 - 1 tablespoon fresh lime juice
# Method Steps:
01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving overhang on two sides for easy removal.
02 - In a large mixing bowl, combine flour, oats, granulated sugar, brown sugar, salt, and cinnamon. Stir in melted butter until the mixture forms moist crumbles.
03 - Add shredded coconut and chopped macadamia nuts to the crumble mixture. Mix until evenly distributed throughout.
04 - Reserve 1 cup of the crumble mixture for topping. Press the remaining mixture evenly into the bottom of the prepared baking pan to form a compact crust.
05 - In a small bowl, combine guava jam and fresh lime juice. Stir until smooth and well blended.
06 - Spread the guava jam mixture evenly over the crust layer. Sprinkle the reserved crumble mixture evenly over the jam, covering completely.
07 - Bake for 30 to 35 minutes, until the topping is golden brown and jam bubbles at the edges. Remove from oven when fully cooked.
08 - Allow bars to cool completely in the pan. Lift out using parchment paper overhang and cut into 16 equal bars using a sharp knife.
