Combine the pumpkin puree, brown sugar, apple cider, granulated sugar, maple syrup, lemon juice, pumpkin pie spice, ground cinnamon, sea salt and ground cloves in a medium sauce pan over medium high heat.
Bring mixture to a boil, stirring frequently. Once it reaches boiling, reduce heat to low and cover the pan.
Continue cooking, stirring occasionally, so the pumpkin butter doesn't burn on the bottom, until thickened, about 20 to 25 minutes.
Remove from heat and let pumpkin butter cool completely before transferring to an airtight container. Store pumpkin butter in the refrigerator for up to 2 weeks.
For a super smooth consistency, use an immersion blender.
