- 1 tsp cinnamon
- ¼ tsp nutmeg
Instructions
- Add Ingredients: Add all the ingredients to a slow cooker and stir well to combine all the flavors thoroughly.
- Cover and Cook: Cover the slow cooker with the lid and cook on high heat for 1 hour, allowing the blueberries to start breaking down and release their juices.
- Blend Mixture: Transfer the cooked blueberry mixture to a blender and blend until smooth to achieve that buttery consistency.
- Return and Evaporate: Pour the blended mixture back into the slow cooker. Prop the lid slightly open with a wooden spoon to let excess liquid evaporate and thicken the butter.

Notes
- Use fresh blueberries for best flavor; frozen can be used but may increase cooking time.

- Ensure you stir the mixture occasionally during the slow cooking to prevent sticking or burning at the edges.
- Allowing the lid to be slightly open during the second cooking phase helps achieve a thicker, more concentrated spread.
