How to Make Blueberry Butter

  2. After a couple of hours, puree the mixture until smooth and velvety using a blender or an immersion blender.
  3. Return the purée to the cooker and continue to cook uncovered for additional time to thicken the spread, stirring occasionally.
  4. Allow to cool, then spoon into jars or use right away.

Serving Ideas

  • Spread on toasted bread, English muffins, biscuits, or French toast for breakfast or snacks.
  • Use as a filling for cakes in place of traditional fruit fillings to add a fresh berry note.

Notes & Variations

Frozen blueberries work well and follow the same timing; they thaw and break down as they cook.

Store blueberry butter in mason jars or an airtight container in the refrigerator for 2–3 weeks. For longer storage, freeze it. This recipe is not intended for water-bath canning.

Stovetop option: Combine ingredients in a medium saucepan and simmer on low to medium heat, stirring frequently until thickened.

Absolutely fantastic! I get asked for this by all my “non able to cook friends”. It is perfect on a big southern biscuit.

  • 3 Tbsp. fresh lemon juice (fresh, not bottled)
  • 1 Tbsp. ground cinnamon
  • ½ tsp. ground nutmeg

Instructions

  • Cover and cook on HIGH for 2 hours.
  • Carefully transfer the contents to a blender, or use an immersion blender in the slow cooker, and blend until completely smooth.
