This Slow Cooker Blueberry Butter is a luscious, spiced fruit spread made by slowly cooking fresh blueberries with brown sugar, honey, lemon, and warming spices.

Ingredients

Scale

Ingredients

  • 3 pounds fresh blueberries
  • 1 ½ cups light brown sugar
  • 1 tbsp honey
  • 1 lemon, zested and juiced
  • 1 tsp cinnamon
  • ¼ tsp nutmeg

Instructions

  1. Combine Ingredients: Add all the fresh blueberries, light brown sugar, honey, lemon zest and juice, cinnamon, and nutmeg into the slow cooker bowl. Stir well to incorporate all the ingredients evenly.
  2. Initial Cooking: Cover the slow cooker with its lid and set it to cook on high for 1 hour, allowing the blueberries to break down and the sugar to dissolve.
  3. Blend the Mixture: After the initial cooking, transfer the blueberry mixture carefully into a blender. Blend until the mixture is completely smooth and free of chunks, achieving a consistent texture.
  4. Return to Slow Cooker: Pour the blended blueberry butter back into the slow cooker. Prop the lid slightly ajar using a wooden spoon to let steam escape and aid evaporation of excess liquid.
  5. Simmer to Thicken: Cook on low heat for an additional 4 to 5 hours. This slow simmer helps to thicken the blueberry butter to the desired consistency.
  6. Store: Once thickened, ladle the blueberry butter into clean jars. Allow to cool, cover, and store in the refrigerator for up to 2 months, ready to enjoy on your favorite baked goods.

Notes

  • Ensure the blueberries are fresh and ripe for the best flavor and natural sweetness.
  • The wooden spoon propped under the lid prevents condensation from dripping back into the mixture, which helps thicken the spread.
  • Smooth blending is essential for a creamy texture, so blend thoroughly.
  • Store in sterilized jars to prolong shelf life.
  • This blueberry butter can be used as a spread, filling, or topping.
