This easy slow cooker strawberry butter recipe makes an addictive, spreadable treat perfect for toast, pancakes, or gifting.
Place the strawberries, honey, sugar, lemon juice, and a pinch of salt into a slow cooker. Stir to combine.
Cover and cook on low for 6-7 hours, stirring occasionally, until the mixture thickens and darkens in color.
Remove the lid and blend the mixture with an immersion blender until smooth (or carefully transfer to a blender in batches).
Continue cooking uncovered on low for another 1 to 2 hours, stirring occasionally, until thick and spreadable.
Stir in the vanilla extract at the end of cooking.
Let cool slightly, then transfer to sterilized jar.
Store in the refrigerator for up to 2 weeks, or freeze for longer storage.
