Guava Jam Bars Coconut Macadamia Oat (Printable)

Buttery layers of sweet guava filling topped with coconut macadamia oat crumble

# 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

# How To Make:

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 to 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.

# Top Suggestions:

01 -
  • The contrast between chewy jam and crispy, golden crumble makes every bite feel indulgent without being heavy.
  • These bars are a conversation starter—most people have never tasted guava in a dessert bar, so you'll get genuine surprise and delight.
  • They're simple enough to make on a weeknight but impressive enough to bring to a potluck and have people ask for the recipe.
02 -
  • Don't skip cooling completely—I learned this the hard way when I cut too early and the jam was still molten, making a mess that tasted great but looked chaotic.
  • The magic happens when the topping is golden but not dark brown, so set a timer and check at 30 minutes rather than walking away.
03 -
  • Lightly toasting your coconut and macadamias separately for 5 minutes before adding them to the crumble elevates the entire bars from good to unforgettable.
  • Use an 8-inch square pan religiously—going bigger or smaller will affect baking time and the ratio of crumble to jam.
