Buttery bars with sweet guava jam and golden coconut macadamia oat crumble topping.

# 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

# Step-by-Step:

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 the 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 mixture for topping. Press the remaining mixture evenly into the bottom of the prepared pan to create an even crust.
05 - In a small bowl, stir together guava jam and fresh lime juice until smooth.
06 - Spread the guava mixture evenly over the crust layer. Sprinkle the reserved crumble mixture uniformly over the jam layer.
07 - Bake for 30 to 35 minutes, until the topping turns golden brown and jam begins to bubble at the edges.
08 - Let cool completely in the pan. Lift out using the parchment overhang and cut into 16 equal bars.

# Expert Advice:

01 -
  • They taste like a vacation in dessert form, but come together faster than you'd expect.
  • The crumble topping stays golden and crunchy even after a few days, making them perfect for grabbing throughout the week.
  • You can swap the guava jam for whatever you have on hand and still get something delicious.
02 -
  • Don't skip the complete cooling step, no matter how impatient you feel—cutting into warm bars means they'll fall apart and the jam will be molten.
  • If your guava jam is very thick from the jar, warming it gently in the microwave for 15 seconds makes spreading infinitely easier.
03 -
  • Using melted butter instead of cold is non-negotiable—it's what turns dry ingredients into those perfect moist crumbles.
  • A squeeze of fresh lime juice in the jam is the secret that keeps everything from tasting one-dimensional and sweet.
