Cannabis Coconut Oil Recipe: Crockpot Method, Ratios & Capsules

Cannabis Coconut Oil Recipe: Crockpot Method, Ratios & Capsules

Coconut oil is the infusion base you reach for when butter is the wrong tool: capsules, vegan baking, topicals, smoothies, and anything that has to sit in a warm kitchen without going off. It is also the easiest fat to infuse well, because there are no milk solids to scorch and no water bath to manage.

This guide covers the parts that are specific to coconut oil: which kind to buy, how much flower to use per cup, a hands-off crockpot method that needs no water, and how to turn the finished oil into evenly dosed capsules. For the theory behind decarbing, our decarboxylation guide goes deeper; this one stays practical.

Which coconut oil: refined, virgin, or MCT

Three products sit on the same shelf and behave differently once infused.

Oil	Room temperature	Flavor	Smoke point	Best for
Refined coconut oil	Solid below about 76°F (24°C)	Neutral	~400°F (204°C)	Baking, savory cooking, capsules kept cold
Virgin (unrefined) coconut oil	Solid below about 76°F (24°C)	Mild coconut	~350°F (177°C)	Sweet bakes, smoothies, topicals
MCT oil	Liquid	Neutral	~320°F (160°C)	Capsules, drops, anything measured by the millilitre

Refined is the default. It carries no flavor into a brownie or a pan sauce, and it solidifies in the fridge so a tablespoon stays a tablespoon. Virgin coconut oil tastes of coconut, which is welcome in a smoothie and unwelcome in garlic bread. MCT oil is coconut oil with the long-chain fats removed; it never solidifies, which is exactly what you want when filling capsules or dosing by dropper, and exactly what you do not want in a cookie recipe that relies on solid fat. The infusion steps below are identical for all three.

One more detail worth knowing: coconut oil is about 82% saturated fat against roughly 63% for butter. THC and CBD are fat-soluble and bind readily to saturated fat, so a cup of coconut oil holds a little more cannabinoid than the same cup of butter before it stops taking any more.

How much flower per cup of coconut oil

The oil has a ceiling. Past roughly 14 grams of flower per cup (200 g) of coconut oil the fat is saturated and extra flower mostly wastes money. Below that, potency scales with the amount of flower and its THC percentage. The table assumes 20% THC flower and the 10% loss most home infusions see.

Batch	Flower per cup of oil	Approximate THC in the batch	Per tablespoon
Light	3.5 g	630 mg	~39 mg
Standard	7 g	1,260 mg	~79 mg
Strong	14 g	2,520 mg	~158 mg

The arithmetic behind it: grams × THC% × 1,000 × 0.9, divided by the 16 tablespoons in a cup. A 7 g batch at 20% THC is 7 × 0.20 × 1,000 × 0.9 = 1,260 mg, which is about 79 mg per tablespoon or 26 mg per teaspoon. Plug your own flower and cup count into the oil calculator and it does that math and gives you a per-serving number for whatever you bake.

[mini-dosage-calculator]

If you are new to edibles, make the light batch. A teaspoon of it is about 13 mg, which is still more than most first-timers should eat in one go; you can always dilute infused oil with plain oil, but you cannot un-infuse it.

Decarb first, every time

Raw flower is mostly THCA, which does nothing until heat converts it. Spread pea-sized pieces on parchment and bake at 240°F (115°C) for 40 minutes, stirring once at the halfway point, until it turns golden and smells toasty. The decarb calculator adjusts the time for other temperatures and for kief or concentrates, and the decarboxylation guide covers sous vide and low-odor options.

Crockpot method (no water, no babysitting)

This is the method the article is named for, because it suits coconut oil better than anything else. Butter needs a water bath so its milk solids do not scorch; coconut oil has none, so it can sit in a slow cooker on its own for hours.

You need: 1 cup (200 g) coconut oil, 3.5-14 g decarbed flower, an optional teaspoon of sunflower lecithin, a slow cooker, a thermometer, cheesecloth, and a glass jar.

1. Melt the coconut oil in the crockpot on LOW with the lid on. Most slow cookers hold 170-200°F (77-93°C) on low; check yours with a thermometer the first time, because "low" varies by brand.
2. Stir in the decarbed flower and the lecithin, if using. The flower should be fully submerged.
3. Cook for 4 to 6 hours with the lid on, stirring every hour. Keep the oil under 200°F (93°C); if it creeps higher, switch to WARM or prop the lid.
4. Switch the cooker off and let the oil cool for 20 to 30 minutes so it is safe to handle but still liquid.
5. Line a fine strainer with two layers of cheesecloth over a glass jar and pour the oil through. Let it drain on its own; squeezing pushes chlorophyll through and makes the oil taste like lawn.
6. Seal, label with the date and the mg-per-tablespoon figure from the table above, and refrigerate.

Small crockpots are often too hot on LOW for a single cup of oil. If yours runs above 200°F, double the batch or put a ramekin of oil inside a water-filled crockpot, which behaves like a sous vide bath.

Stovetop method when you are in a hurry

Same ingredients, two to three hours instead of four to six. Melt the oil in a small saucepan over the lowest burner setting, add the flower and lecithin, and hold the oil between 160 and 180°F (70-82°C) with a thermometer in it. It should shimmer and give off a faint steam, never bubble. Stir every 20 minutes, then strain as above. The stovetop needs more attention than the crockpot because a gas burner on low can still push the oil past 200°F, and every excursion above that costs you THC.

Sous vide when smell matters

Seal the melted oil and flower in a zip-top bag with the air pressed out, and hold it in a 185°F (85°C) bath for four hours. Nothing evaporates, so the kitchen stays close to odor-free, and the temperature cannot drift. Strain after the bag has cooled enough to handle.

Straining, cloudiness, and why lecithin helps

Freshly strained cannabis coconut oil is often cloudy or slightly green, and both are normal. The color is chlorophyll and the cloudiness is fine plant matter and water released from the flower; it settles as the oil cools. Sunflower lecithin is worth the teaspoon if you plan to use the oil in anything water-based, such as gummies or drinks, because it keeps the oil dispersed instead of separating; our lecithin guide explains the amounts. It does not raise potency, despite what forums say, but it does make each spoonful more consistent.

Turning it into capsules

Capsules are where coconut oil beats butter outright. A size 00 gelatin or vegetarian capsule holds about 0.9 ml, and coconut oil weighs close to 0.9 g per ml, so each capsule holds roughly 0.8 g of oil.

Work out the dose per capsule from the per-tablespoon figure. A tablespoon is 15 ml, so the standard batch above (79 mg per tablespoon) is about 5.3 mg per ml, or roughly 4.7 mg in a 00 capsule. The light batch gives about 2.4 mg per capsule and the strong batch about 9.5 mg. If you want 10 mg capsules, use the strong batch or go right up to the saturation ceiling of 14 g per cup.

1. Set a capsule-filling tray with empty 00 capsules, bottoms in the tray.
2. Warm the infused oil until just liquid, around 80°F (27°C) for refined coconut oil. MCT oil is already liquid and skips this step.
3. Draw the oil into a syringe or a dropper and fill each capsule bottom to just below the rim.
4. Cap immediately and set the capsules in the fridge for 30 minutes so the oil solidifies and stops seeping.
5. Store in an airtight jar in the fridge, and label the jar with mg per capsule.

Refined coconut oil capsules should stay cold; they soften above about 76°F (24°C). MCT oil capsules are more forgiving at room temperature but still keep longest chilled. The capsule guide covers gelatin versus vegetarian capsules and how to test a batch before dosing anyone else.

Storage and how fast potency fades

Coconut oil resists rancidity better than butter, but light and heat still degrade THC. Refrigerated in a sealed glass jar it holds well for about a month; frozen in ice-cube portions it keeps six months with little loss. At room temperature it is stable for a week or so, though it will go soft and the top layer can pick up off flavors. Wrap the jar or use an amber one; the edibles storage guide has shelf-life details for finished bakes.

Coconut oil or butter?

Pick coconut oil when the recipe is vegan, when you are making capsules or topicals, when you want the longer fridge life, or when you simply do not want to manage a water bath. Pick butter when the flavor is the point, such as shortbread, toast, or a pan sauce. The infusion temperatures are the same for both; only the handling changes, and butter's water bath is the extra step this article lets you skip.

FAQ

How much cannabis coconut oil should I take?

Dose by milligrams, not spoons. Work out the mg per teaspoon of your batch (a standard 7 g per cup batch is about 26 mg per teaspoon), measure a 2.5-5 mg starting dose, which is roughly a fifth of a teaspoon of that batch, and wait two hours before taking more.

Can I use MCT oil instead of coconut oil?

Yes, and for capsules or drops it is the better choice because it stays liquid. Infuse it exactly the same way. It will not work in bakes that need solid fat, and it has a lower smoke point, so keep it under 200°F during infusion.

Do I need to add water when infusing coconut oil?

No. Water is a butter trick that keeps milk solids from scorching. Coconut oil has no milk solids, so infuse it neat; adding water only means an extra step separating the two afterwards.

Why did my cannabis coconut oil turn out weak?

Almost always one of three things: the flower was not decarbed or was decarbed too cool, the oil ran above 200°F long enough to degrade THC, or the flower's THC percentage was lower than assumed. Recheck the decarb step first, then rerun your numbers in the oil calculator.

How long does cannabis coconut oil last?

About a month in the fridge, six months in the freezer, and about a week at room temperature. It rarely spoils inside that window, but potency and flavor both drift, so date the jar.

Gear for this job: refined coconut oil is the flavor-neutral base this recipe wants, and grade-90 cheesecloth strains it clean without pressing bitterness through (affiliate links).
