If you’re interested in making your own cannabis-infused edibles, brownies, cookies, and bars are among the easiest and most reliable to start with. Here’s a simple guide for beginners that covers infusion, baking, and safe THC dosing.

1. Infusing Your Fat: Decarb & Cannabutter (or Oil)

Before you bake, you need to decarboxylate your cannabis — that’s how you convert inactive THCA into psychoactive THC. Many home methods assume about 70-80% efficiency for decarb and infusion. (The Clever Root)

Here’s a basic process:

  1. Grind your cannabis lightly and spread it on a baking sheet.
  2. Bake it at a low temperature (around 225–250 °F) to decarb, taking care not to burn the cannabinoids.
  3. After decarbing, infuse it into butter or oil by simmering gently — do not exceed ~350 °F while baking your edibles, as high heat can degrade THC. (Greenlight Cannabis Doctors)
  4. Strain out the plant material so you’re left with a THC-infused fat.

Mix this cannabutter (or infused oil) thoroughly into your brownie, cookie, or bar batter to ensure even THC distribution. Poor mixing is a common mistake and can lead to inconsistent potency. (Smokeland)

2. Baking Your Edibles: Brownies, Cookies, Bars

Once your infused fat is ready, you can substitute it for regular butter or oil in nearly any recipe.

  • For brownies, use a standard boxed mix or scratch recipe and simply swap in your cannabutter.
  • For cookies, do the same, ensuring the dough is mixed thoroughly.
  • For bars, use a recipe that relies on butter/oil (rather than water-based ingredients) so THC stays distributed.

Be mindful of oven temperatures: baking too hot can degrade potency, while too low may undercook the batter. (Greenlight Cannabis Doctors)

After baking, let your edibles cool completely before cutting them into servings. Use a ruler (for brownies or bars) or, ideally, a kitchen scale to divide them evenly.

3. Calculating THC Dosage & Safe Guidance

Dosing is critical — edibles hit harder and last longer than smoked cannabis. (theathenaforum.org) Here’s how to estimate your dose:

  1. Figure out total THC in your cannabis: multiply the grams of flower by its THC percentage. (atriumstore.com)
  2. Adjust for efficiency: most home infusions will extract around 70–80% of the total THC. (The Clever Root)
  3. Divide by number of servings: total activated THC ÷ number of brownies/cookies/bars = mg of THC per piece. (BudBuddies)

As for how much to take:

  • Beginners: 2.5–5 mg THC per serving is widely recommended. (Veriheal)
  • Casual users: ~5–10 mg per serving. (Veriheal)
  • More experienced: 10–20+ mg, depending on tolerance. (The Clever Root)

Experts also suggest that first-time edible users may start even lower (e.g., 1.25 mg) if they are especially sensitive. (NATA)

4. Safety Tips & Responsible Use

  • “Start low, go slow.” After eating an edible, wait at least 2 hours before taking more — its effects may take time to fully develop. (Greenlight Cannabis Doctors)
  • Label your edibles. Clearly mark the THC content per serving so you and others know what you’re eating. (atriumstore.com)
  • Store safely. Keep your edibles in childproof containers and out of reach — they often look like regular food. (Cincinnati Children’s Hospital)
  • Be aware of onset and duration. Edible effects can peak 2–3 hours after consumption and last much longer than inhaled cannabis. (theathenaforum.org)
  • Avoid overheating. Stay under ~350 °F when baking to preserve THC potency. (Greenlight Cannabis Doctors)

Final Thoughts

Making your own THC brownies, cookies, or bars can be a fun and rewarding way to enjoy cannabis — but it comes with responsibility. By carefully decarboxylating, using a reliable infusion method, calculating your dose, and starting very low, you can enjoy a safer, more controlled experience. If you’re unsure about potency, consider using a dosage calculator (many are available online) to help guide you. (glowcalculator.com)
