Why you should try this blueberry butter recipe
There’s nothing quite like making fruit butter, and this homemade fruit butter does not disappoint. The sense of accomplishment that comes with making it on top of always having your favorite kinds of fruit butter on hand is a win-win. This crockpot blueberry butter can be used for many things (check the serving suggestions below), and I highly recommend giving this recipe a try. Just a word of caution, though… making blueberry butter can become addicting. 🙂
Blueberry butter (or apple butter or any fruit butters) do not contain real butter! It’s more of a silky jam.
Recipe Ingredients
- Blueberries: You can use fresh or frozen blueberries. I used two-18 ounce packages of blueberries. Make sure they are rinsed and dried well before using. (You can use frozen berries instead of fresh).
- Brown Sugar: Add the perfect amount of sweetness to the blueberry butter.
- Lemon Juice: You’ll want to use the juice of fresh lemons and not bottled lemon juice. We are just using the juice, not any lemon zest.
- Spices: Nutmeg and cinnamon add slightly warm, nutty, woody, and sweet flavors.
Step-by-Step Directions
Step One – Add the blueberries, brown sugar, nutmeg, cinnamon, and lemon juice to the crock pot.
Step Two – Stir everything together until all the blueberries are combined with the spice, lemon, and sugar.
Step Three – Cover and cook on HIGH for 2 hours.
Step Four – Use an immersion blender to puree the blueberry jam into a silky texture or until it reaches your desired consistency (or you can use a food processor or blender). Cook for an additional hour with the lid completely off. Serve and enjoy!
How to serve
- This blueberry butter makes the perfect topping for vanilla ice cream (or any flavor of your choice).

Can this be made with a brown sugar substitute?
You would want to use much much less, for they can be much sweeter.
Hi!
Just made! Love the flavor… for some reason a little runny… any thoughts on how to thicken a bit?
Also, do you serve this warm over english muffins/pancakes etc? Or cold like a jelly?
Thanks!
You can leave it in the slow cooker on low without the lid on. It will thicken a little as in chills. I serve this cold.
About how much does this make? Want to get some in jars for tge freezer
I did not measure, I apologize.
I made this so yummy I even put it on pancakes
Can you prepare this on the stove if you do not have a slow cooker?
Yes, it will work very well on the stove.
Why can’t you can this?
I am not a canning expert, you’ll want to make sure it has the right amount of acidity.
Plenty of acidity in blueberries (citric, tartaric, malic, etc.) alone, plus the addition of lemon juice (citric acid) makes this a perfect candidate for water bath canning. I’ve already canned one batch of this over eight months ago, and it’s still fine.
You can use bottled lemon juice just make sure its real, not the additive garbage one. That’s what I did and it was perfectly fine
Yes you can can it. I can a lot. Hot water bath 15 minutes.
WOW , I MADE THIS AND ITS SO GOOD. I USED FROZEN BLUEBERRYS JUST COOKED IT LONGER. THANK U!
If you use frozen blueberries to you need to thaw them
No, they will thaw quickly in the slow cooker.
Hi Sarah, how much is a serving? Thanks.
I don’t know measure. Serving amounts are just an estimate.
This sounds delicious! Can anyone tell me how much one serving is?
How long will they store in freezer.
About 6 months.
Can you leave out the nutmeg?
Yes!
If you freeze it, how long can you keep it after you thaw it?
Thank you
