How to Make Weed Edibles: Decarb, Infuse, and Dose Them Right

You’ve probably eaten an edible. Maybe you’ve eaten one or two more than you meant to. But have you ever made your own weed edibles?

Almost every edible out there, from brownies to gummies to a little infused oil over popcorn, comes from the same simple process. Learn it once and you can turn nearly any recipe into an edible. 

So, how do you make weed edibles? Making weed edibles is a three-step process: decarboxylate (bake) your flower to activate the THC, infuse it into a fat like butter or oil over low heat, then cook or stir that infused fat into whatever you’re making. The one step people skip — and the reason homemade edibles go sideways — is the math: knowing how strong each piece actually is, and we’ll make sure you don’t have to wing it. 

Rather skip the kitchen altogether? Our edibles menu is lab-tested, perfectly dosed, and ready when you are.

The 3 Steps Behind Every Edible

Here’s the whole thing in one breath. Every cannabis edible is made by (1) activating the THC in your flower with heat, (2) dissolving it into a fat, and (3) using that fat in food. The bit that makes it click: THC isn’t water-soluble, but it loves fat — which is why edibles start with infused butter or oil instead of just tossing ground-up flower into the batter (a common first-timer move, and one we’ll steer you around). Nail these three steps and the specific recipe barely matters.

Step 1: Decarboxylate Your Flower (Don’t Skip This)

Here’s a detail that saves a lot of disappointment: raw cannabis won’t get you high, no matter how much of it you eat. That’s because the flower is full of THCA, an inactive acid that only turns into the THC you’re after once it’s heated. When you smoke or vape, the lighter handles that instantly. For edibles, you do it in the oven first — a step called decarboxylation, or “decarbing.”

To decarb, bake your flower at about 225–240°F (107–115°C) for 30–40 minutes, until it’s dry and a light golden-brown. Here’s the play-by-play:

1. Break it up. Pull your flower into small, even pieces and spread it in a single layer on a parchment-lined baking sheet.
2. Bake low and slow. Pop it in at 225–240°F (107–115°C) for 30–40 minutes, until it’s dry and a light golden-brown.
3. Let it cool. Give it a few minutes before you handle it — it’ll be a little crumbly, which is exactly what you want.

Low and slow is the whole game here. Crank the heat and you’ll scorch off the THC and the terpenes you worked to keep. And don’t rush it to save time: a hurried decarb is the number-one reason homemade edibles come out weak.

Step 2: Infuse It Into Butter or Oil

Now we pull that activated THC out of the flower and into a fat, where it’s happy to live. Butter or oil? Well, that depends on what you’re making. Butter is the classic for baking; a neutral oil like coconut, MCT, or olive is the more versatile pick for dressings, savory dishes, and gummies. Good news, either way, the method’s the same, and our friendly team is always happy to talk it through if you get stuck.

How to Make Cannabutter or Canna-Oil

A good starting ratio is about 7 grams (a quarter-ounce) of flower per 1 cup of butter or oil. Here’s the method, start to finish:

1. Combine. Add your decarbed flower and your fat to a saucepan or slow cooker.
2. Infuse low and slow. Hold it around 160–200°F for 2 to 3 hours, stirring whenever you wander past. It should barely simmer — never a rolling boil.
3. Strain. Pour it through cheesecloth into a clean jar, give it a good squeeze to get every last drop, and toss the spent plant material.
4. Butter with water? If you added a splash of water to keep it from scorching, chill the jar so the butter firms up on top, then lift it right off the water.

When you’re ready to actually bake with it — brownies and all — we’ve got the recipes in our guide to cooking with cannabis.

Step 3: Do the Dosing Math (The Part Everyone Skips)

This is the step it’s tempting to skip, and the one we’d never let you skip. Because you’re making a whole batch at once, you want to know roughly what’s in each piece — guessing is how a nice evening turns into “I think I took too much.” 

From behind the counter

The number-one thing we hear from folks making edibles at home isn’t “how do I infuse it” — it’s “I think I made them too strong.” Almost every time, it traces back to this one step: eyeballing the dose instead of doing the math. Run the numbers once and you’ll never be the one texting the group chat.

The Simple Potency Formula

Start by estimating the total THC in your flower:

Grams of flower × THC% (as a decimal) × 1,000 = milligrams of THC (theoretical maximum).

So 7 grams of flower at 20% THC works out to 7 × 0.20 × 1,000 = 1,400 mg of THC as your ceiling. You won’t actually capture all of it — home decarbing and straining leave a little behind — so it’s smart to plan for maybe half to three-quarters of that landing in the finished oil. 

 The move that keeps you safe: divide the batch total by the number of servings to get your per-piece dose. That one bit of arithmetic is the whole ballgame.

One quick label tip: if your package lists THCa instead of “Total THC,” multiply that number by about 0.87 first — a little THC is lost when the flower is heated. If it already says “Total THC,” that’s done for you, so use the number as-is.

A Quick Dosing Reference

Here’s how per-serving strength changes with the same batch, using that 1,400 mg example (before efficiency losses — your real numbers will be lower):

Batch THC (theoretical)	Servings in the batch	Approx. THC per serving*
~1,400 mg	24 servings	~58 mg (very strong)
~1,400 mg	48 servings	~29 mg (strong)
~1,400 mg	100 servings	~14 mg (moderate)
~1,400 mg	140 servings	~10 mg (a common single serving)

*These are theoretical maximums before extraction losses, so treat them as a ceiling, not a promise. For reference, a common store-bought single serving is about 5–10 mg of THC, and plenty of people start around 2.5 mg. A good rule of thumb: when in doubt, make it weaker. You can always eat two — you can’t un-eat one.

Start Low, and Respect the Wait

This is the one we really want you to hear. Because homemade potency is always an estimate, treat your first edible like a taste test. 

Have a small piece, then wait at least 2 hours before having more — edibles are slow on purpose, and reaching for a second one too early is the most common mistake there is. 

Our guide to how long edibles take to kick in explains exactly why that wait matters, and our THC dosage guide helps you pick a starting amount. Start low and go slow — it’s the advice we give everyone.

A Simple Starter Recipe: Cannabis-Infused Oil

If you want one versatile thing to make first, make infused oil. It works in nearly any recipe — drizzle it, bake with it, or stir it into honey or a salad dressing.

You’ll need:

• ~7 g decarbed flower
• 1 cup coconut or olive oil

Make it:

1. Combine the flower and oil in a saucepan or slow cooker.
2. Hold at 160–200°F for 2–3 hours, stirring occasionally and never letting it boil.
3. Strain through cheesecloth into a clean jar.
4. Label it with the date and your estimated potency (your calculator number from above).

That’s it — you now have a base for countless edibles. Add a spoonful to a brownie mix, whisk it into a salad dressing, or stir it into tea or honey.

Making Your Edibles Taste Better

Let’s be honest — a homemade infusion can taste a little… green. That grassy, herbal note is completely normal, and the good news is it’s easy to tame. A few ways to make edibles taste better:

• Pick a bold carrier and pairing. Coconut oil and browned butter carry flavor beautifully, and rich, punchy flavors — chocolate, peanut butter, coffee, citrus, honey, cinnamon — cover the herbal taste far better than something plain and delicate.
• Add an extract. A little vanilla, peppermint, almond, or citrus extract goes a long way toward masking the cannabis flavor.
• Don’t over-cook the infusion. Keeping the heat low and straining well — squeeze the plant material, but don’t force the last bit of sludge through — keeps the green taste down.
• A pinch of sunflower or soy lecithin while it infuses helps everything blend smooth and even. Optional, but nice for texture.
• Try infused honey or simple syrup. Stir your canna-oil into honey, or make an infused simple syrup, to sweeten tea, coffee, or lemonade without a strong weed taste.

Aunt Mary’s favorite: brown the butter before you infuse it, then finish whatever you bake with a splash of vanilla and a pinch of flaky sea salt. It turns “tastes like weed” into “tastes like a bakery” — it’s the little trick she swears by.

How to Store Homemade Edibles Safely

Homemade infusions and edibles keep best in an airtight container in the fridge (infused oil and butter last a few weeks; freeze for longer). Two rules matter most: label everything clearly with the date and estimated dose so no one mistakes it for regular butter, and keep it locked away from children and pets — homemade edibles look exactly like ordinary food, which is precisely the danger. In New Jersey, making edibles for your own personal use is for adults 21 and older only.

Common Edible Mistakes to Avoid

Most homemade-edible horror stories trace back to a handful of fixable errors.

•  Skipping the decarb gives you weak, barely-active edibles. 
• Cooking too hot — boiling the infusion or baking above ~340°F for long stretches — burns off THC. 
• Skipping the math leaves you blind to how strong each piece is.
•  Uneven mixing concentrates the dose in a few servings, so stir your batter thoroughly. 
• And taking more too soon turns a pleasant evening into a rough one. Measure, mix well, start low, and wait.

What our budtenders wish you knew

Two habits save more batches than anything else: a patient, low-and-slow decarb, and stirring your batter like you mean it so the dose isn’t all hiding in one corner brownie. If you remember nothing else from this page, remember those two — and when in doubt, come ask us. It’s what we’re here for.
