Guava Jam Coconut Macadamia Oat Bars (Printable)

Buttery bars with sweet guava jam topped with coconut, macadamia, and 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 It:

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 flour, oats, granulated sugar, brown sugar, salt, and cinnamon. Stir in melted butter until mixture forms moist crumbles.
03 - Add shredded coconut and chopped macadamia nuts to the mixture, stirring until evenly combined.
04 - Reserve 1 cup of the crumble mixture for topping. Press remaining mixture evenly into the bottom of prepared pan to form the crust base.
05 - In a small bowl, stir together softened guava jam and lime juice until smooth and well combined.
06 - Spread guava jam mixture evenly over the crust layer. Sprinkle reserved crumble mixture uniformly over the jam layer.
07 - Bake for 30 to 35 minutes, until topping is golden brown and jam is bubbling at the edges.
08 - Cool completely in the pan. Using parchment overhang, lift out and cut into 16 equal bars.

# Expert Advice:

01 -
  • The contrast between crispy, buttery crumble and jammy sweetness feels luxurious but comes together in under an hour.
  • Macadamia nuts and toasted coconut elevate these bars beyond ordinary, making them feel like a bakery find from your own oven.
02 -
  • If your guava jam is stiff straight from the jar, warming it gently for 20 seconds in the microwave makes spreading effortless and prevents you from accidentally punching holes in your crust.
  • Toasting your coconut and macadamia nuts separately for 5 to 7 minutes before mixing transforms the entire flavor profile from nice to genuinely unforgettable.
03 -
  • Measuring your ingredients by weight rather than volume, if you have a scale, takes the guesswork out of getting the crumble texture just right every single time.
  • Don't skip the parchment overhang—it transforms removal from a demolition project into something smooth and professional that makes you feel like you actually know what you're doing.
