Salty, sweet jam bars made with thick guava jam sandwiched between a buttery macadamia nut, shredded coconut, and oat crumble topping. An easy-to-make, simple tropical treat for breakfast, brunch, or any day of the week!
Preheat the oven to 350ºF. Lightly grease and line an 8x8 baking dish with parchment paper. Set aside.
In a large bowl or stand mixer, mix butter, flour, brown sugar, and granulated sugar until well combined. Fold in the oats, macadamia nuts, and shredded coconut flakes. The dough will be thick, buttery, and crumbly. Don't be alarmed if it looks dry, that's totally ok!
Evenly press 2/3 of the dough into the prepared baking dish using the bottom of a cup. Make sure the layer is as even as possible so it cooks evenly.
Make sure the jam is warm, at room temperature, or cold so it spreads easily. Top the crust with a thick layer of the guava jam making sure it is evenly spread over the crust.
Using your fingers, break apart the remaining dough and sprinkle it on top of the guava jam so it looks like a crumble topping. Personally, I don't like to cover the jam completely with the crumble because I like to see some of the jam oozing out of the bar. You do you!
Bake the bars for 35-38 minutes or until golden brown and the guava jam is bubbling. Careful the guava will be scorching.
Allow to cool completely before slicing with a sharp knife. You may have to clean the knife as you go since the guava jam gets sticky. Serve for brunch or dessert. Enjoy!
