How to Make Cannabutter at Home

Making cannabutter is an easy but methodical process perfect for beginners. Heat weed, immerse in melted butter and steep.

Cannabutter (or weed butter) is regular butter that’s been infused with dry cannabis to use for cooking, baking, or spreading onto a hunk of bread. Making weed butter is an easy but methodical process that any beginner can do.

I started taking a CBD oil a few years ago when I developed trouble sleeping and peri-menopausal induced anxiety. The sleep I could help by doing these few things every night.

The anxiety was tougher.

It saw me greet every morning by jumping out of bed, saying here we go again, and promptly forgetting how breathing works. In and out, I knew that much, but how often?

Should I count my breaths? I feel like I’m breathing too many times, why can’t I get a deep breath? I’m dizzy, let’s curl up in a ball on the floor next to the dirty cat food dish while I contemplate why my stomach is in a constant state of trying to turn itself inside out.

It was that experience and the success of using CBD that prompted me to grow my own cannabis plants for making weed butter. If you like growing things, I’m an experienced gardener who also writes for publications like The Old Farmer’s Almanac – you can see my best vegetable gardening tips here .

My meno is pausing. And this THC butter recipe helps.

Cannabis can be split into 2 groups – THC dominant strains and CBD dominant strains. I recommend a 1:1 for making your own weed butter. That means your pot strain will have 1 part THC to 1 part CBD.


7 – 10 grams of dried, decarboxylated cannabis (CBD or THC) – About 1 cup

1 cup of butter

1 cup water

Step 1 – Decarbing

  • Decarb your cannabis by breaking it into pieces and laying it on a parchment lined baking sheet. Bake for 40 minutes in a 240 F oven.
  • Remove the decarbed cannabis from the oven and let it cool a bit. It’ll have lost some of its green colour and turned crispy.

For a superior product work with the buds for this (on the left), not the stems or the leaves (on the right). Having said that, you can make marijuana butter using stems, leaves, shake weed and kief.

Whatever garbage pot parts you have – they can be made into cannabutter!

If you’re wondering how to decarb kief, leaves and stems – do it the exact same way. By heating in a 240 F oven for 40 minutes.

Step 2 – Grinding

  • Now you have to either cut or grind the buds so that it’s smaller but not a fine powder, which is best for infusing. You can use a grinder (I have a fancy gold, metal grinder) or just cut it up with scissors.

Gold grinder on AMAZON in Canada.

Gold grinder on AMAZON in US – (currently not for sale in the U.S., but it does pop up every now and then)

TIP: A weed grinder is also perfect for grinding dried herbs. I use one for the grinding up the thyme, basil, oregano and sage that I grow and dry. It makes it the perfect consistency for cooking.

Step 3 – Infusing

  • Combine 1 cup butter and 1 cup water in a pot and bring to the simmer until butter melts. Once you add your cannabis in the next step you don’t want your mixture to go over 200 F.

Anything between 160 F and 200 F is O.K.

  • Add your decarbed cannabis to the pot of butter and water and stir.* Let it steep at a temperature of around 180 for 3 hours stirring fairly often to keep things mixed up. Use a thermometer in your pot so you can keep an eye on it. If your mixture is at a boil you KNOW you’ve gone over 200 F. :(

NOTE: The reason you add water is to prevent your butter from scorching and burning. You’ll separate the butter and water later.


*I have made this cannabutter recipe two ways. With the above controversial method which inserts the Sous Vide stick right in the cannabutter as well as the more traditional method of setting the jar of cannabutter into a pot of water, with the Sous Vide stick in the water. I’ve found putting the stick right in the butter makes a more consistent product. But you do you! Either way works.

NOTE: You can also use a slow cooker and make crock pot cannabutter but remember to stir it the odd time and use an instant read digital thermometer to make sure you’re staying at 180 F.

Step 4 – Straining & Storing

  • After 3 hours take the pot off the heat (or turn off the Sous Vide) and strain your mixture through multiple layers of cheesecloth to strain the cannabis from the butter.
  • Squeeze the cheesecloth to get all the butter in it out.
  • Refrigerate the mixture of butter and water overnight. The next day the butter will have hardened at the top of the water and you can use a spoon to lift it out and put it in a new dish.
  • The butter will be grainy and weird. Mash it with a fork and once it’s softened enough, whisk it to smooth it out. If you want to be an overachiever you can use an electric beater to get it really smooth.
  • Refrigerate until you want to use it.

In order for Cannabutter to have any of the beneficial effects of the CBD or THC your cannabis flower (bud) needs to be activated by decarboxylating (decarbing) it.

More on Decarboxylation

It’s a big scary, sciencey looking word, but all it means is you need to heat up the cannabis to activate it. You need to decarb both THC and CBD to get the benefits out of them.

In fact, until you decarb the cannabis, what it contains is THCA and CBDA. It’s only when you heat it that it becomes THC and CBD.

You decarboxylate cannabis by heating it on a baking sheet in the oven at 240 F for 40 minutes.

NOTE: If you’re wondering how to make cannabis oil it’s the same as making cannabutter. All the steps and measurements are the same. Instead of 1 cup butter, use 1 cup oil. Olive, grape, MCT (unrefined coconut oil) & avocado oil all make excellent carrier oils. *For the steeping phase DO NOT ADD WATER.

Orrrr – you can make it all in one machine. Both The Magical Butter machine and the higher priced Levo II can decarboxylate and infuse butter or oil all in the handy casing of a small countertop appliance.


Dosing is a bit of a crapshoot but you can guide yourself if you know what you worked with to make your butter.

You can use this THC calculator for determining how strong your cannabutter is read this blog post on how to calculate cannabis dosing and stregth yourself.


  • To figure out dosing for yourself without all the math, just spread a small amount (1/4 tsp or so) onto a piece of bread and eat it. See how you feel 1 hour later and adjust from there.
  • Using more flower does not = more potent. The butter can only absorb so much of the cannabinoids so stick to a maximum 1:1 ratio. 1 cup of butter to 1 cup decarbed flower.
  • Homemade infused cannabutter will last for about 2 weeks in your fridge.
  • If you’ll only use it occasionally store it in the freezer.
  • If you find your butter isn’t strong enough the easiest way to make cannabutter stronger is to just take more of it. If you add 1/2 teaspoon to toast, add 3/4s or 1 full teaspoon. So basically eat twice as much.

To make cannabutter stronger you can also remelt the butter and infuse it again with a few grams of stronger cannabis and hope your butter still has room in it to grab more of that THC.

What to Make With Cannabutter

  • You can use it in everyday cooking like regular butter. Just substitute 1 part regular butter with 1 part weed butter. It’s as easy as that.
  • Use it on corn on the cob.
  • Melt it and drizzle it on movie night popcorn.
  • Toss with cooked pasta and parmesan cheese.
  • For your first attempt at cooking with cannabis try these delicious, classic pot brownies made with cannabutter.
  • You can also just slather weed butter onto a hunk of bread about an hour before bedtime. It’s an effective alternative to sleeping aids like pills or sleepy-time tea. (without filling your bladder up before bed)
  • Cannabutter can be used in baking, but as you can also try baking with weed itself when you’re feeling all pro about your cannabis cooking skills.

Kick the cat dish out of the way and enjoy effortless breathing and sleeping like an actual well adjusted human person who doesn’t have completely unpredictable hormone levels and mood swings.

How do you make cannabutter in an apartment?

Ah yes. The stink factor. Baking cannabis in the oven for decarbing does create an odor. If you have an oven vent, run it on high. This will help a bit. But if you want a completely odor free way to make weed butter you might want to look into one of the small infusion machines like The Magical Butter Machine which you can get on Amazon. These machines don’t completely 100% eliminate all of the marijuana scent, but they reduce them to very minimal levels.

How do you make CBD cannabutter?

Whether you’re making CBD butter or THC butter, they process is exactly the same. Heat the cannabis to decarb, mix it with warmed butter, then steep.

How much weed do you need to make cannabutter?

You can use any amount that you want as long as you follow the 1:1 ratio measured in cups. So 1 cup butter & 1 cup weed. Or 1/4 cup butter & 1/4 cup weed. And so on.

Why did my cannabutter mold?

Cannabutter needs to be stored in the refrigerator. Unlike regular butter, this very special butter has another ingredient in it – weed. It’s that distinction that makes it more prone to mold. Also, leaving crumbs or anything like that in the butter will cause it to mold more quickly.

Keep your butter clean and in the fridge and it should last for 2 weeks.

Can you freeze weed butter?

You bet you can. Cannabutter freezes perfectly either in premeasured doses, or as an entire stick. Science says it’ll last for 6 months but experience says it’ll still be fine after that.

Why is my weed butter watery?

There are two possible reasons for watery butter.

1. Your fridge just isn’t cold enough to make the butter solidify properly. Stick it in the freezer to get it in good solid form. But take it out before the water freezes as well. (fat freezes more quickly than water)

2. The butter might not be solidifying because of what the cow ate, believe it or not. The saturated and unsaturated feed an animal takes in is directly related to the fat in products made from that animal. Again the fix for watery weed butter is to just put the cannabutter in the freezer for a bit.

How much cannabutter does an ounce make?

One ounce of weed will make 4 cups of cannabutter.

.25 ounces = 7 grams
7 grams pot = 1 cup cannabutter


1/4 ounce (7 gr) weed = 1 cup cannabutter
1/2 ounce (14 gr) weed = 2 cups cannabutter
3/4 ounce (21 gr) weed = 3 cups cannabutter
1 ounce (28 gr)weed = 4 cups cannabutter

Oh hi. You’re still here. I know this was a mammoth post. As luck would have it, I’m well rested and feeling good so I have all the energy in the world to write 2,200 word posts.

Also, I don’t mean to brag but, I’m kind of a world champion breather. I don’t even have to think about it.

    Hello Karen. I can’t get seeds, plants or products with any THC in it where I live 🙄. I am able to aquire 50/50 THC/CBD tincture however. Do you know how I can use that to make cannabutter? My husband has a chronic painful autoimmune disease that reacts well to the tincture.

    • Karen says:

      HI Caroline! If that works for him, you probably don’t need to mess around with making butter anyway. :) It can only be made by steeping flower as far as I know. Tinctures are a bit different than a regular steeped oil. ~ karen!

      • Caroline says:

        Thanks Karen. I guess the old adage applies, if it’s not broke, don’t fix it!

  2. Rafiq Tawa says:

    Also i was suffering from anxiety and this cannabutter helped me alot in this issue. Also the remedy is tasty. I got form medical marijuana card from –

  3. Heather Powell says:

    I knew I loved you! Your blog is the only thing I follow on the internet! I wish you were my neighbor. Lol! Anyway, in your pictures the buds look very green. Do you cure and dry first? Thanks for this post!

    • Karen says:

      Hi Heather, thanks! I’m not sure which photo you’re referring to, but they did still look remarkably green after decarbing, but were definitely browner than they were to begin with. ~ karen!

  4. Gretchen sexton says:

    Maybe I could just buy it from you?

  5. Carol says:

    What is ig? I would like to follow for tips on how to grow. We do not have very good luck with growing, my husband uses for pain I don’t use but would like to learn how to make edibles .

  6. Carol says:

    Great post, I been wanting a simple recipe for this, but a cup of bud and you only get a cup of butter, guess my question is do you get more out of the butter then you would get out of the bud? If you smoked it ? Just trying to figure out money wise where you get the most benefit.
    Thank you for you great post.

  7. Kim Dunshie Herning says:

    Good Job, detailed and concise instructions ! I love Cannabis and Cannabis loves me. I use my homemade cannabis concoctions to treat arthritis, carpal tunnel and insomnia in myself. I too started with cannabutter (dairy, or coconut oil) and as my tolerance eeked upwards I was forced to learn to make concentrate. It is amazing what can be achieved with cannabis medicine. Thank you for joining the conversation and teaching the methods to give others the knowledge to help themselves and others.

  8. Kl says:

    For anyone who isn’t interested in butter (or interested in using this as a face/body cream— hell yes it’s AMAZING for your skin) coconut oil can be subbed for butter.

    There is also a way to make it in the oven in a mason jar with less fuss. The internet can tell you how. 😆💁‍♀️

  9. Lauren from Winnipeg says:

    If you are new to THC, remember that one person’s dose is not necessarily what will work for you. Everyone processes THC differently and your size has zero to do with it. You can be 6’4” and 250 lbs with a low tolerance and feel shitfaced with 10% THC or you can be 5’ nothing at 115 lbs with a high tolerance and function normally at 20%. It’s trial and error. Start small and work your way up.

    Karen – did you buy plants or did you grow from seed? It’s been quite a few years since I’ve grown any plants and thats when seeds came with the weed! – Anna
