Turn ordinary berries into a smooth, irresistible spread with this slow cooker blueberry butter. It captures all the summer goodness in every bite. Unlike regular jams that can be too sweet, this butter slowly develops rich flavor layers as it cooks down.

I came up with this blueberry butter after a farm trip left me swamped with more berries than we could eat. Watching those plain berries turn into this thick, concentrated spread felt almost like magic happening in my kitchen.

Basic Components

  • 6 cups fresh blueberries: Forms the main body with their gorgeous color and taste
  • 1 cup light brown sugar: Brings sweet, toasty notes that work well with blueberries
  • ¼ cup honey: Gives a nice gloss and helps keep the texture smooth
  • Zest of 1 lemon: Adds brightness from the fragrant oils in the skin
  • 2 tablespoons lemon juice: Cuts through sweetness with a touch of tang
  • ½ teaspoon cinnamon: Introduces a warm background flavor that doesn't take over

Your blueberries really matter for this spread. While frozen ones work in a jam (no pun intended), fresh berries picked at just the right time will give you the brightest flavor and most beautiful color.

Quick Instructions

Getting Berries Ready:
Clean blueberries well and let them dry. Take out stems and any bad berries.
First Cooking Stage:
Mix everything in your slow cooker. Let it cook on high for 1 hour until berries get soft.

Long Cooking Time:

This slow cooker blueberry butter has become one of my go-to homemade treats – it's what everyone asks me to make again and again.

Frequently Asked Questions

→ Can I use frozen blueberries instead of fresh ones?
Absolutely! Toss frozen berries straight in—no thawing is needed. Just keep in mind it might take a bit longer since they release more liquid.
→ How can I tell when the blueberry butter is done?
When a spoon's back gets coated and holds its shape after a finger swipe, it's ready! Try placing a dab on a cold plate—it shouldn't spread, and the color will have deepened.
→ Is it possible to use less sugar in this?
You can trim the sugar a bit, but it does help with consistency and shelf life. Avoid going below 1 cup. Honey makes a good alternative too!
→ How do I make this shelf-stable for storage?
For long-term storage, use water bath canning. Boil filled jars for 10 minutes (longer at higher altitudes) and stick to recommended preservation guidelines from trusted sources.
→ What creative ways can I use blueberry butter?
Try it on crepes, thumbprint cookies, or layered cakes. Swirl into cheesecake or BBQ sauce, glaze meat, or use in smoothies. It also makes a thoughtful gift!

Yield: 32 Servings (About 4 cups (8 half-pint jars))

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

Ingredients

→ Main ingredients

01 1½ cups packed light brown sugar
02 1 tablespoon raw honey
03 3 pounds of ripe blueberries
04 1 lemon, juiced and zested
05 ¼ teaspoon nutmeg, ground
06 1 teaspoon cinnamon powder

Instructions

Step 01

Toss the blueberries, brown sugar, honey, lemon zest, lemon juice, cinnamon, and nutmeg into your slow cooker. Give it a good stir to blend it all together.

Step 02

Put the lid on your slow cooker and set it to high for an hour. This helps soften the blueberries and pulls the juices out.

Step 03

Carefully move the hot blueberry mix into a blender and blend it until it's smooth. You might need to split it into smaller batches if your blender is small. Be super careful blending hot stuff!

Step 04

Pour the smooth mixture back into the slow cooker. Prop the lid open a little using the handle of a spoon or a chopstick so some steam can escape, which helps it get thicker.

Step 05

Let it simmer on low heat for another 4-5 hours. Stir it here and there if you can. When it's thick enough to coat the back of a spoon, it's ready.

Step 06

While the mixture is still hot, scoop it into clean 8oz mason jars. Leave about ¼ inch of room at the top of each jar to allow for expansion.

Step 07

Let the jars cool completely before sealing them with lids and putting them in the fridge. It'll stay good for up to two months when refrigerated.

Notes

  1. Yields around 4 cups of blueberry butter—just right to fill 8 small (8oz) jars.
  2. Want it silkier? You can run it through the blender one more time after it's all cooked.
  3. Like it sweeter? Taste the mixture before jarring and add more honey or sugar if you'd like.

Tools You'll Need

  • 4 to 6-quart slow cooker
  • A blender or stick blender
  • 8oz mason jars and matching lids
  • A ladle for scooping
  • Wooden spoon
