Guava bars combine the sweetness of guava with the nuttiness of oats and the buttery goodness of a shortbread crust to create a delicious combination of flavors for your dessert table.
Prepare a nine-by-13-inch baking pan by lining the bottom and up and over all four sides with parchment paper to help remove the bars after they’re done. Set it aside.
For the crust, beat the butter and sugar together for several minutes until it is light and fluffy. Beat in the salt and flour until the mixture is smooth, and then press it evenly into the bottom of the prepared baking pan.
Cover the entire surface of the crust layer with slices of guava paste. You can cut it into smaller pieces to fill gaps, too. (You may have just a bit left over for you to snack on.)
Add the oats, butter, salt, sugar and flour to a food processor and pulse until the mixture kind of looks like wet sand and everything is well combined.
Sprinkle the topping evenly over the guava and bake for 40 to 45 minutes or until the topping is golden brown.
Let the bars cool completely before using the parchment paper to remove them from the pan. Slice them and store in an airtight container.
