Slow Cooker Blueberry Butter

Introduction

Slow Cooker Blueberry Butter is smooth, sweet, and full of rich berry flavor. It is not made with dairy butter. Instead, it is a thick fruit spread made by slowly cooking blueberries until they become soft and concentrated. The result is a deep purple spread that tastes like sweet blueberry pie filling, but smoother.

This recipe is simple and mostly hands-off. Your slow cooker does most of the work. You just add the ingredients, stir sometimes, and let it cook slowly. As it cooks, your kitchen will smell amazing.

Blueberry butter is perfect on toast, pancakes, biscuits, or even stirred into yogurt. If you love fruit spreads and homemade treats, this recipe is a must-try.

Cooking Time & Prep Time

• Prep Time: 10 minutes
• Cooking Time: 4–6 hours (slow cooker)
• Cooling Time: 30 minutes
• Total Time: About 5–6 hours
• Servings: About 2 cups

Ingredients

Here is everything you need.

• 6 cups fresh or frozen blueberries
• ¾ cup granulated sugar (adjust to taste)
• 1 tablespoon lemon juice
• 1 teaspoon lemon zest (optional)
• ½ teaspoon ground cinnamon (optional)
• Small pinch of salt

Step-by-Step Instructions

Follow these simple steps to make your blueberry butter.

Step 1: Add Ingredients to Slow Cooker

Place the blueberries into the slow cooker.

Add sugar, lemon juice, lemon zest, cinnamon (if using), and salt.

Stir everything together.

The blueberries will release juice as they cook.

Step 2: Cook on Low

Cover the slow cooker with the lid.

Cook on LOW for 4–6 hours.

Stir every hour if possible. This helps prevent sticking.

The berries will become very soft and juicy.

Small tip: If your slow cooker runs hot, check after 4 hours.

Step 3: Blend the Mixture

Once the blueberries are fully soft, turn off the slow cooker.

Use an immersion blender to blend the mixture until smooth.

If you do not have one, carefully transfer the mixture to a blender in batches.

Blend until silky and smooth.

Be careful. The mixture will be hot.

Step 4: Thicken the Blueberry Butter

After blending, leave the lid slightly open.

Cook on LOW for another 1–2 hours.

This allows extra moisture to evaporate and helps the mixture thicken.

Stir occasionally.

The blueberry butter is ready when it coats the back of a spoon and holds its shape slightly.

Step 5: Cool and Store

Turn off the slow cooker.

Let the blueberry butter cool completely.

It will thicken more as it cools.

Spoon into clean jars or airtight containers.

Store in the refrigerator.

Your homemade blueberry butter is ready to enjoy.
