Step‑by‑Step Instructions for Slow Cooker Blueberry Butter
Step 1: Combine Ingredients
In your slow cooker, add fresh blueberries, light brown sugar, honey, lemon zest and juice, cinnamon, and nutmeg. Stir the mixture gently until all the ingredients are well-combined, ensuring the blueberries are evenly coated with sugar and spices. This step takes about 5 minutes and sets the foundation for your delicious Slow Cooker Blueberry Butter.
Step 2: Cook on High
Cover the slow cooker with its lid and set it to cook on high for 1 hour. During this time, the blueberries will soften and release their juices, creating a fragrant syrupy mixture. You’ll know it’s ready when the blueberries appear plump and bubbling, filling your kitchen with a delightful aroma.
Step 3: Blend for Smoothness
Once the cooking time is complete, carefully remove the lid and let the mixture cool slightly. Using an immersion blender or a regular blender, blend the blueberry mixture until it reaches a smooth and creamy consistency. This step takes about 2-3 minutes and transforms your Slow Cooker Blueberry Butter into a spreadable delight.
Step 4: Evaporate Extra Liquid
Return the blended mixture back to the slow cooker, propping the lid open with a wooden spoon to allow steam to escape. Set your slow cooker to low and let it cook for an additional 4 to 5 hours, stirring occasionally. This will help thicken the butter, giving it that rich texture reminiscent of a fruit jam.
Step 5: Jar and Refrigerate
Once the blueberry butter has thickened to your desired consistency, turn off the slow cooker and let it cool for about 10 minutes. Ladle the warm blueberry butter into glass jars, sealing them tightly once cool. Store in the refrigerator for up to 2 months, ready to spread on toast, pancakes, or anything your heart desires!

Make Ahead Options
These Slow Cooker Blueberry Butter will save you precious time during busy mornings! You can prepare the ingredients by washing and measuring the blueberries, sugar, honey, and spices up to 24 hours in advance, storing them in the refrigerator. Simply combine everything in the slow cooker and follow the initial cooking steps when you’re ready to enjoy this delightful spread. Additionally, after making the butter, it can be refrigerated in glass jars for up to 2 months or frozen for longer storage. To maintain quality, ensure jars are sealed tightly and refrigerate as soon as they cool. When you’re ready to serve, just scoop out the amount you need and savor the taste of homemade bliss!
