Ingredients List
Main Ingredients:
- 4 cups fresh or frozen blueberries
- 1 cup granulated sugar (adjust to taste)
- 1/4 cup lemon juice (about 2 lemons)
- 1 teaspoon ground cinnamon (optional)
- 1/4 teaspoon salt
- 1/4 cup unsalted butter (optional, for added richness)
Timing
Preparation takes about 10 minutes, and cooking in the slow cooker will take around 6-8 hours on low. In total, expect to devote about 8 hours from start to finish—but the hands-on time is minimal!
Step-by-Step Instructions

Step 1: Prepare Blueberries
If using fresh blueberries, rinse them under cool water. If using frozen, no need to thaw; you can add them straight to the slow cooker.
Step 2: Combine Ingredients
In the slow cooker, combine the blueberries, sugar, lemon juice, ground cinnamon (if using), and salt. Stir until well combined.
Step 3: Slow Cook
Cover the slow cooker and set it to low for 6-8 hours or until the blueberries are soft and the mixture is syrupy.
Step 4: Blend the Mixture
Once cooking is complete, use an immersion blender to puree the blueberry mixture until smooth. If you don’t have an immersion blender, you can transfer the mixture to a regular blender, but be cautious with the hot mixture.
Step 5: Add Butter (Optional)
If desired, stir in the unsalted butter until melted and fully incorporated into the blueberry spread for added richness.
Step 6: Cool and Store
Let the blueberry butter cool to room temperature. Transfer to sterilized jars and seal tightly. It can be stored in the refrigerator for up to 2 weeks or frozen for up to 6 months.
