Take the guava paste and put it in a small plate. Heat it up in the microwave for 8 seconds. Mash the paste until smooth.
In a big bowl add the butter and paste. Using a hand blender, mix it until all the guava is completely combined with the butter. Serve and enjoy!
Notes
This recipe was made using a hand blender but you can also mix this by hand. But if you don't want to feel small guava pieces in the butter, it is best to make this in a food processor.
You can make a guava butter compound by simply adding the finished butter to parchment paper, plastic film, or wax paper. Then roll it to make a cylinder and tie up the corners. Chill until the butter hardens and then you're ready to use the compound butter.
