# Directions:
01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a large bowl, combine the flour, oats, granulated sugar, brown sugar, salt, and cinnamon. Stir in melted butter until the mixture forms moist crumbles. Add coconut and chopped macadamia nuts, mixing to combine.
03 - Reserve 1 cup of the mixture for the topping. Press the remaining mixture evenly into the bottom of the prepared pan to form the crust.
04 - In a small bowl, stir together guava jam and lime juice until smooth. Spread evenly over the crust.
05 - Sprinkle the reserved crumble mixture evenly over the jam layer.
06 - Bake for 30–35 minutes, until the topping is golden brown and the jam is bubbling at the edges.
07 - Let cool completely in the pan. Lift out using the parchment overhang and cut into 16 bars.
