Welcome fall into your home with the warm smell and taste of this Slow Cooker Apple Butter! This recipe uses a combination of sweet Honeycrisp apples and tart Granny Smiths for a unique apple butter that's bursting with flavor. Spread it on toast, swirl it into oatmeal or yogurt, or spoon it over pancakes to transform anything into a cozy fall treat!
Add apples, brown sugar, spices, cider, and salt to a large (preferably 6-quart) slow cooker.
Cover and cook on low for 8-9 hours, until the apples are completely soft.
Puree the apples with an immersion blender (or in batches using a regular blender) until the mixture is smooth.
Cook uncovered on low for 3-5 hours, stirring occasionally until the butter is thick and spreadable. Stir in vanilla extract and lemon juice, taste, and add more flavoring as needed. Cool, then transfer to jars.
Notes
Storage: You can fill about 8-10 half-pint jars or 4-5 pints with the apple butter.
Silky smooth butter: If you prefer silky smooth butter, peel the apples first or press through a fine strainer after blending.
Test for doneness. Butter that is done should be a deep mahogany brown, and it should be thick enough to mound on a spoon and not run off right away. You can also dip a spoon in the apple butter and drag it in a line. If the line stays clear and doesn't fill in with liquid, it's done. Just remember to keep a good eye on the butter during the final few hours of cooking, as this is when it's most likely to burn!
