Banana jam is made with firm, ripe bananas, sugar, fresh lemon juice, and vanilla, creating a smooth, caramel-flavored spread that’s perfect for toast or dessert.
Add the peeled bananas into a large bowl. Using a potato masher, mash the bananas very well. If you do not have a potato masher, use a fork to mash the bananas.
Add the white sugar, brown sugar, vanilla and lemon juice.
Stir until blended.
Add this banana mixture to the slow cooker.
Cook on HIGH for 1.5 hours. You can cook this for 2 hours on high if you want a darker jam.
Stir and serve hot over ice cream or put into jars and refrigerate or freeze. The jam will thicken as it cools.

Notes
Bananas are naturally high in pectin, which helps the jam set, but banana jam won’t be as thick as traditional fruit jams. For the best texture, use slightly green or just-ripe bananas—overripe ones can make the jam too thin. Keep in mind that the mixture will thicken more as it cools.Add a cup of sliced strawberries before mashing for strawberry-banana jam.
