Here’s a step-by-step guide to making a great pot brownie using butter in a professional manner with some key tips to help you control the potency, texture, and flavor of the final product:

Materials & Ingredients

  • Baking Tray/Pan (oven-safe), Parchment Paper, Small SaucePan, Fine Strainer/Cheesecloth, Mixing Bowl, 20 x 20 cm Baking Pan.
  • Ground cannabis flower (7-10g) or shake/trim (10-14g) (well-dried).
  • Unsalted Butter (your amount).
  • Brownie Mix (or Classic Batter): 2 Eggs, 120g Sugar, 70g Flour, 45g Cocoa Powder, Pinch of Salt, Vanilla.

Step 1 – Decarb (Converts THCA → THC)

Spread the cannabis thinly across parchment paper. Bake at 115-120°C for 35-45 minutes while stirring every 15-20 minutes. A light golden color is what you are aiming for, but avoid browning. Decarbing is important as it unlocks THC in cannabis, which will otherwise not produce any effects.

Step 2 – Cannabutter (Clean Flavor + Consistent Dose)

Combine melted butter and 30-50ml of water in a small saucepan and place on low heat (do not let it boil). Add decarbed cannabis to the melted butter mixture. Simmer for 75-90 minutes while stirring occasionally. Cool slightly, then strain through cheesecloth and press gently. Allow it to chill. If you added water during the cannabutter process, simply remove the solid butter from the top and discard the water.

Tip: To maintain terpenes and avoid the “grassy” taste of infused products, make sure to use a short, gentle infusion method.

Step 3 – Brownie Batter

Replace all or most of the fat in your favorite brownie recipe with cannabutter (if you’d like milder brownies, replace half of the fat with regular butter). Mix until just combined. Over-mixing creates tough brownies.

Step 4 – Bake

Preheat the oven to 170-175°C. Place a parchment-lined baking sheet inside the oven. Bake for 18-25 minutes (insert toothpick to check for moist crumbs). Once baked, allow to completely cool prior to cutting (this allows the potency of the edibles to develop).

Dosing (Basic Math You Can Trust)

Input (Example) THC % Amount of Cannabutter Produced Efficiency Approximate Amount of THC in Whole Pan
8 g flower 18% 170g 70% ≈ 1000mg

As you may be aware, home infusions typically achieve a maximum of ~60-75% extraction efficiency. Therefore, the chart is using 70% to provide a safe and reliable estimate.

To calculate the amount of THC per square, divide the total amount of THC in the pan by the number of squares you intend to cut (in the example provided, if you cut 20 squares, each would contain approximately 50mg of THC. If you wanted each square to contain approximately 5-10mg of THC, either reduce the amount of cannabutter used in the recipe (i.e. combine with regular butter), use less flower, or cut the squares smaller (for instance, if you cut the squares into 40 instead of 20, each would be approximately 25mg).

Serving Guidelines

For first-time servings, take 5-10mg of THC and wait 2-3 hours to reassess. As mentioned previously, edible products tend to creep in slower and longer (approximately 6-8 hours). Always label your edibles and store them safely away from children and pets. Store refrigerated for up to one week, or frozen for a longer period of time.

Taste and Texture Fixes

  • Too “Herbal”: Shorten infusion time, add a bit of espresso powder or additional vanilla to counterbalance herbal flavors.
  • Dry/Crumbly: Pull the brownies out of the oven earlier than suggested, as they will continue to set as they cool.
  • Uneven Potency: Ensure that you’ve strained your cannabutter thoroughly, and also ensure that you’ve mixed your batter consistently. Cut the brownies into even-sized squares.

Why Butter?

Butter provides flavor, produces a traditional crumb, and also effectively binds the cannabinoids. For those who are dairy-free, coconut oil is another option; however, you’ll need to adjust cooking temperatures, and the brownies will likely have a different consistency.

Quick Recap

  • Decarb Gently.
  • Low and Slow Infusion Method.
  • Use cannabutter in place of the fat called for in the original recipe (all or most of it).
  • Cool, Cut Evenly, Label, and serve responsibly.
