Crockpot Blueberry Butter

Featured in Sweet Creations and Baking Adventures.

Crockpot Blueberry Butter turns simple blueberries into a rich, deeply flavored spread with hardly any work. Unlike traditional preserves, this fruit butter is smooth, not too sweet, and lets the fresh berry flavor stand out. The slow cooker works its magic by slowly reducing and intensifying the berries’ natural sweetness alongside warm spices like cinnamon and nutmeg. A splash of lemon cuts the richness, making it a bright and balanced treat. Long cooking gently caramelizes the sugars for a jam-like alternative that's versatile and easy to make. Use it on toast, swirl into yogurt, drizzle over pancakes, or pair with cheese for something fancy. It’ll fill your home with an irresistible aroma during the process!

This crockpot blueberry butter turns regular berries into a rich, smooth spread that bottles up summer in every bite. Unlike the run-of-the-mill fruit jams that tend to be too sweet and flat, this butter builds rich flavor layers during its low and slow cooking time.

I tried making this blueberry butter for the first time after coming home from a berry farm with way too many blueberries to eat before they went bad. Watching those ordinary berries turn into this deep, intense spread was truly amazing.

Basic Components

  • 6 cups fresh blueberries: Forms the main ingredient giving rich color and taste
  • 1 cup light brown sugar: Brings in warm, sweet notes that work well with the fruit
  • ¼ cup honey: Adds glossiness and helps keep the spread smooth
  • Zest of 1 lemon: Lifts the flavor profile with aromatic oils from the skin
  • 2 tablespoons lemon juice: Cuts through sweetness with a touch of tang
  • ½ teaspoon cinnamon: Offers a cozy background flavor that doesn't take over

Your blueberry quality really matters for the end result. Though frozen ones will work if you're in a bind, freshly picked ripe berries give you the brightest taste and most beautiful color.

Simple Steps

Fruit Prep:
Clean and dry your blueberries well. Take off any stems and toss out mushy ones.
First Cooking Phase:
Mix everything in the slow cooker. Let it go on high for 1 hour until the berries get soft.
Smoothing Step:
Blend everything until totally smooth with your regular or stick blender.
Long Cooking Time:
Put it back in the slow cooker. Cook on low with the lid slightly open for 4-5 hours till it gets thick.
Putting Away:
Pour into clean jars, leaving space at the top. Let them cool all the way before putting in the fridge.

This slow cooker blueberry butter has become one of my trademark DIY goodies – it's the recipe everyone always asks me for.

Frequently Asked Questions

→ Can I swap fresh blueberries for frozen?
Of course! Frozen ones work perfectly. Just toss them in straight from the freezer. Keep in mind they might take a little longer to cook since they’ll release extra liquid.
→ When’s the blueberry butter ready?
You’ll know it’s done when it sticks to the back of a spoon and stays put when you run your finger through. If you put a dab on a cold plate, it shouldn’t spread much, and it’ll take on a dark purple hue.
→ Can I use less sugar?
You can cut back a bit, but sugar helps with the texture and keeps it fresh. Try not to go below 1 cup for the batch. Swapping some sugar for honey works too!
→ How can I make this shelf-stable?
You’ll need to can it the right way. Use a water bath to process sealed jars for 10 minutes. Make sure to check up-to-date canning safety tips, like from the National Center for Home Food Preservation.
→ What creative ways can I use it?
Other than waffles and toast, try it in crepes, thumbprint cookies, or between cake layers. Mix it into cheesecake, use it on grilled pork or chicken, or add to barbecue sauce or smoothies. It’s also a thoughtful homemade gift!

Cuisine: American

Yield: 32 Servings (Roughly 4 cups (fills around 8 half-pint jars))

Dietary: Vegan, Vegetarian, Gluten-Free, Dairy-Free

Ingredients

→ Main ingredients

01 1 lemon, both its zest and juice
02 ¼ teaspoon of nutmeg, ground
03 1½ cups of brown sugar, light
04 1 tablespoon of honey
05 3 pounds of fresh and ripe blueberries
06 1 teaspoon cinnamon, ground

Instructions

Step 01

Throw the blueberries, brown sugar, honey, lemon zest and juice, cinnamon, and nutmeg into your slow cooker. Give it all a good stir so everything is coated and mixed up nicely.

Step 02

Put the lid on the slow cooker and set it to high. Leave it for an hour. This gives the blueberries a chance to soften and release their juices.

Step 03

Carefully pour the hot blueberry mix into a blender and blend until it’s smooth. Don’t overfill—work in smaller batches if needed. Be extra careful when handling hot liquids!

Step 04

Dump the blended blueberry mixture back into your slow cooker. Let a little steam out by propping the lid open with a wooden spoon or a chopstick. This setup helps it reduce and thicken.

Step 05

Turn the heat down to low and let it cook for another 4 to 5 hours. Stir once in a while if you can. You’ll know it’s ready when it sticks to a spoon and feels nice and thick.

Step 06

When the blueberry butter reaches the texture you want, scoop it into clean 8oz mason jars while it's still hot. Leave just a bit of space at the top (about ¼ inch).

Step 07

Let those jars cool down fully before putting the lids on. Once they’re sealed, store them in the fridge. They’ll stay good for up to 2 months.

Notes

  1. You’ll end up with around 4 cups of blueberry butter, which is just the right amount for 8 small (8oz) jars.
  2. After cooking, if you want it even silkier, blend it once more before jarring.
  3. Try it out before packaging. If it needs more sweetness, toss in extra sugar or a touch of honey to your liking.

Tools You'll Need

  • A slow cooker (4-6 quart size works best)
  • A blender or stick blender (immersion type)
  • Mason jars (8oz size) with matching lids
  • A ladle to scoop things into jars
  • A wooden spoon for stirring and propping up the lid
