Key Takeaways
- Cannabutter requires decarboxylation at 230°F for 30 minutes before infusion — skipping this step is the number one reason homemade edibles fail to produce effects
- The full process takes approximately 2 hours from start to finish, with only 20 to 30 minutes of active hands-on time required
- One cup of unsalted butter infused with 3.5 grams of 20% THC flower yields approximately 560mg of usable THC after accounting for 80% transfer efficiency
- Maintain infusion temperature between 160°F and 190°F for 45 to 60 minutes and never let the mixture boil, which degrades cannabinoids
- Store finished cannabutter in an airtight container for up to 3 months refrigerated or 6+ months frozen

What Is Cannabutter and Why Do Edible Recipes Need It?
Cannabutter is cannabis-infused butter made by simmering decarboxylated flower in unsalted butter, serving as the base fat for most homemade edible recipes because THC and CBD are lipophilic compounds that bond with fats.
Cannabutter is regular unsalted butter infused with cannabinoids extracted from cannabis flower. Think of it like herb-infused butter, but instead of rosemary or thyme, the active compounds from cannabis dissolve into the fat.
Butter works exceptionally well because of its high fat content. Cannabinoids, specifically THC and CBD, are lipophilic compounds that bond with fats. When flower is placed in warm butter, the cannabinoids naturally migrate from the plant material into the butter fat, creating an infused cooking ingredient.
Cannabutter distributes THC and CBD evenly throughout finished products like brownies, cookies, and sauces. With proper preparation, approximately 80% of the THC from your flower transfers into the butter, making it easy to calculate dosing.
How Long Does It Take to Make Cannabutter from Start to Finish?
Making cannabutter takes approximately 2 hours total, including 30 to 40 minutes for decarboxylation, 45 to 60 minutes for infusion, and 1 to 2 hours for cooling — with only 20 to 30 minutes of active hands-on time.
Want to make it faster?
If you’re searching how to make cannabutter fast, the best shortcut is making the process efficient, not aggressive:
- Keep your cannabis coarsely broken up (not powder)
- Use controlled heat (avoid boiling or frying your butter)
- Don’t assume “longer infusion = stronger butter.” Past a certain point, you’re often just extracting more green, bitter flavors.
Bottom line: cannabutter doesn’t have to take all day, but the “fast” version still respects the two non-negotiables: decarb and gentle infusion.
What Is Decarboxylation and Why Is It the Most Important Step?
Decarboxylation is the process of heating raw cannabis at 230°F for 30 minutes to convert inactive THCA into active THC — without this step, your edibles will not produce psychoactive effects regardless of how much flower you use.
Raw cannabis flower contains THCA (tetrahydrocannabinolic acid), not THC. THCA is the inactive precursor that does not produce psychoactive effects. Gentle heat converts THCA into THC through decarboxylation.
The optimal temperature is 230°F (110°C) for 30 minutes. This range efficiently converts THCA to THC without degrading cannabinoids or burning terpenes.
Step-by-step decarb process:
Preheat oven to 230°F — use an oven thermometer because home ovens often run 10-25 degrees off
Break flower into small, popcorn-sized pieces (do not grind to powder)
Spread evenly on parchment-lined baking sheet in a single layer
Bake 30-40 minutes, stirring gently every 10 minutes
Remove when flower appears light golden-brown and feels dry and slightly crumbly
How Do You Calculate Cannabutter Dosing and Potency?
Cannabutter potency is calculated by multiplying the cannabis weight in grams by the THC percentage, then multiplying by 0.80 to account for the approximate 80% transfer rate during infusion.
Formula: (weight in grams x THC% x 1000) x 0.80 = total mg THC in batch
Example: 3.5g of flower at 20% THC = 3.5 x 0.20 x 1000 = 700mg total x 0.80 = 560mg usable THC
Strength Level | Cannabis per Cup Butter | Approx Total THC | Per Tablespoon (~16/cup) |
|---|---|---|---|
Mild | 1-2 grams | 160-320 mg | 10-20 mg |
Standard | 3.5 grams | ~560 mg | ~35 mg |
Strong | 7 grams | ~1,120 mg | ~70 mg |
Always test a single small dose and wait 2 full hours before consuming more.
What Are the Step-by-Step Instructions for Stovetop Cannabutter?
Stovetop cannabutter is made by melting 1 cup unsalted butter with 1/4 cup water, stirring in decarboxylated cannabis, and maintaining 160°F to 190°F for 45 to 60 minutes before straining through a fine mesh strainer.
Equipment: small saucepan or double-boiler, cooking thermometer, wooden spoon, fine mesh strainer, heat-safe container with lid.
Ingredients: decarboxylated cannabis, 1 cup unsalted butter, 1/4 cup water (optional but recommended for beginners to prevent scorching).
Steps for Stovetop Cannabutter:
- Melt 1 cup unsalted butter and 1/4 cup water over low heat until fully liquid
- Stir in decarboxylated cannabis, ensure all plant material is fully submerged
- Maintain temperature between 160°F and 190°F for 45-60 minutes, stir every 10-15 minutes, never let it boil
- Pour through fine mesh strainer into a heat-safe container — do not squeeze the strainer, let gravity work for cleaner taste
- Refrigerate 1-2 hours, lift off the solid butter layer and discard the water underneath
Finished cannabutter should have a pale to mid-green tint. Bright green color or very herbal flavor indicates too much plant matter was extracted.
Is a Slow Cooker or Stovetop Method Better for Cannabutter?
Both methods produce equivalent cannabutter potency — the slow cooker offers more convenience and lower scorching risk while the stovetop method is faster at 45 to 60 minutes versus 2 to 3 hours.
Feature | Stovetop | Slow Cooker |
|---|---|---|
Active Time | 20-30 min | 5-10 min |
Total Time | ~1.5 hours | ~3-4 hours |
Scorching Risk | Moderate (requires monitoring) | Low (set and forget) |
Odor Level | Higher | Lower |
Temperature Control | Manual (thermometer required) | Automatic (LOW setting) |
Best For | Experienced cooks, faster results | Beginners, hands-off approach |
How Long Does Cannabutter Last and How Should You Store It?
Cannabutter stays potent for 2 to 3 months in an airtight refrigerated container and 6+ months in the freezer — discard immediately if it develops a sour smell or visible mold.
Method | Duration | Container | Notes |
|---|---|---|---|
Refrigerator | 2-3 months | Airtight glass jar | Keep away from light |
Freezer | 6+ months | Wrapped in parchment, then sealed bag | Label with date and potency |
Room temperature | Not recommended | N/A | Butter spoils quickly unrefrigerated |
What Recipes Work Best with Cannabutter?
Cannabutter substitutes directly for regular butter in brownies, cookies, sauces, pasta dishes, and toast — avoid high-heat frying above 350°F which degrades THC and reduces potency.
Start by substituting half the butter in a recipe with cannabutter to control potency. Avoid high-heat frying and searing since THC degrades above 350°F. Cannabutter works best in baking (325-350°F) and gentle stovetop cooking like sauces, pasta finishing, and toast.
Using Your Stovetop Cannabutter
You can use cannabutter in almost any recipe that calls for butter—brownies, cookies, banana bread, chocolate sauces, pasta finishes, garlic toast, and more.
Two quick guidelines:
- Avoid high heat (frying, searing) which can degrade THC.
- Substitute slowly: You don’t need to replace all butter in a recipe. Many beginners use half cannabutter, half regular butter to keep dosing manageable.
Next, we’ll walk through consistent dosing math so you know exactly what you’re working with and never end up with accidental “mystery brownies.”
Making Cannabutter With Shake & Trim (To Avoid a Bitter Taste)
Using shake or trim is a budget-friendly way to make cannabutter, and it works just as well as flower—as long as you manage flavor. Shake usually tastes cleaner; trim can carry more chlorophyll, which is why some batches turn out “grassy.”
Here’s how to get good results with both.
Use the Same Infusion Method, With Two Adjustments
- Don’t grind shake or trim.
Both already have small particle size. Grinding creates powder, which extracts more bitterness. - Strain through a fine mesh (no squeezing).
Chlorophyll and fine sediment are the main sources of harsh flavor. Give it time to drip.
Keep the Infusion on the Shorter Side
A 45–60 minute infusion window helps avoid over-extracting plant flavors, especially with trim. Longer simmers don’t mean stronger butter—they often just mean greener butter.
Optional: “Butter Wash” for Milder Flavor
If your cannabutter tastes too herbal, melt it with a bit of warm water, chill, lift off the solid butter, and repeat once. This removes some chlorophyll without affecting potency.
Bottom line: Shake makes excellent cannabutter. Trim works too—you just need gentler handling and a lighter touch with heat.
How to Make Slow Cooker Cannabutter (Crock Pot Method)
If you prefer “set it and forget it,” the slow cooker version of how to make cannabutter in a slow cooker or how to make cannabutter in a crock pot is your best friend. It keeps the temperature steady and requires minimal stirring.
How to Do It
- Add butter, decarbed cannabis, and a splash of water to your slow cooker.
- Set to LOW. Most slow cookers run around 160–190°F, right in the infusion sweet spot.
- Cook for 2–3 hours, stirring once or twice.
- Strain gently and refrigerate until the butter separates and sets.
Pros
- Extremely beginner-friendly
- Less odor and less monitoring
- Harder to scorch the butter
Cons
- Slightly longer infusion time
- Some slow cookers run hot, avoid the HIGH setting
This method is ideal for anyone who prefers consistency over stovetop babysitting.
Small-Batch Cannabutter (Using Just 2–3 Grams)
You don’t need a full ounce, or even an eighth, to make infused butter. If you’ve only got a couple grams left, you can still make a perfectly usable batch.
Example: How to Make Cannabutter With 2 Grams
If your cannabis is around 20% THC, then:
- 2 grams contains roughly 320 mg THC total
- Infuse it into ½ cup of butter for a moderate-strength cannabutter
- Infuse into 1 cup for something milder and easier to portion
Why Make a Small Batch?
- Great for first-timers testing potency
- Easy to blend into a single recipe without leftovers
- Lets you try different strains without committing to a full pound of butter
Just follow the same decarb and stovetop steps, only the butter volume changes.
Start Infusing Cannabutter Like a Pro with Story Cannabis
Cannabutter doesn’t have to be complicated. Once you understand decarboxylation, gentle heat, and basic dosing, you can make infused butter that’s consistent, predictable, and easy to use in any recipe.
Keep your heat low, avoid over-grinding, and strain patiently for the best flavor. If you’re using shake or trim, shorter infusions and fine filtering make a big difference. And remember: potency is flexible, you can always adjust by changing how much butter or cannabis you use.
When you’re ready to make a batch, stop by your local Story Cannabis in Maryland, Arizona, or Ohio. Our budtenders can help you choose the right flower or shake for edibles and walk you through THC percentages so you can dose your butter confidently.
Making Cannabutter FAQs
Do you really need water in the butter infusion?
You don’t have to use water, but it helps prevent scorching and makes straining easier—your butter solidifies on top, water sinks below. If you prefer pure butter, skip the water and just keep your heat low. Both methods work; water simply gives beginners a wider margin of error.
Can I mix cannabutter with regular butter?
Absolutely. Blending infused butter with regular butter is the easiest way to adjust potency for different recipes. If your cannabutter ends up stronger than expected, dilute it until each tablespoon feels manageable. Many home cooks use a 50/50 blend for everyday recipes.
Can I use cannabutter in any recipe?
Mostly, yes. Just avoid high-heat frying, which degrades THC. For baking, you can replace some or all of the regular butter with cannabutter. If you want a lower potency, mix cannabutter with plain butter until you reach a comfortable strength.
How long does homemade cannabutter last?
Stored in an airtight container, cannabutter keeps 2–3 months in the fridge and 6+ months in the freezer. Light and air slowly degrade cannabinoids, so keep it sealed and use opaque containers when possible. If it smells sour or develops mold, discard and make a fresh batch.
Can I use cannabutter for sautéing or frying?
Infused butter loses potency at high heat. It’s fine for gentle stovetop cooking—like finishing veggies, pasta, or toast—but avoid pan-frying or searing. If you want infused foods at higher temperatures, add cannabutter after cooking instead of using it as the primary cooking fat.
Can I use coconut oil or ghee instead of butter?
Absolutely. Cannabis infuses into any high-fat, food-safe cooking fat, including ghee, coconut oil, avocado oil, and even olive oil. The process is the same: decarb, gently heat the fat, infuse, strain, and chill.
Potency and dosing math stay the same across all fats. Just follow the same low-heat infusion method and skip the optional water step when you’re not using butter.
Why does my cannabutter taste too grassy?
Grassy flavor results from over-grinding before decarb, infusing longer than 60 minutes, or squeezing the strainer. Use the Butter Wash technique to remove chlorophyll from already-made cannabutter.
How do I know if decarboxylation worked?
Properly decarbed cannabis appears light golden-brown, feels dry and slightly crumbly, and has a toasted aroma. Bright green color means undercooked.
