Mash bananas until mostly smooth; set a medium saucepan over medium heat.
Stir in bananas, crushed pineapple with its juice, sugar, lemon juice, salt, and cinnamon.
Bring to a gentle bubble, then lower heat. Simmer, stirring often, until thick and glossy, 18–22 minutes.
Fold in shredded coconut and vanilla; cook 1–2 minutes to meld flavors.
Remove from heat. Cool 10 minutes, then spoon into clean jars. Chill until set.
