Best recipe for marijuana brownies made from dry ice hash (kief)

If you’re looking best recipe for marijuana brownies made from dry ice hash (kief), check our our guide on how to make marijuana brownies with kief below.

We use kief that is collected using the dry ice hash method using trim and popcorn buds because it’s a simple way to extract the trichomes (the tiny crystals which contain THC). Kief adds a lot less plant flavor to the cannabutter in the brownies than if straight plant material is used, which results in a better tasting pot brownie.

You can also make weed brownies using this recipe with cannabutter prepared using butane hash oil (AKA BHO, shatter, ear wax, etc.), or cannabutter made from marijuana flowers or trim, bubble hash, or scissor hash.

Marijuana brownie ingredients

To prepare these fudge weed brownies you will need the following ingredients:

  • 1/2 cup butter (1 stick)
  • 1 cup white sugar
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all purpose flour
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder

How to make marijuana brownies:

  1. Preheat oven to 350 degrees.
  2. Grease an 8×8″ pan (using vegetable oil spray is easiest) and lightly dust the pan with flour. This will make it easier to remove brownies from pan once cooked.
  3. In large saucepan, melt your prepared cannabutter and remove from heat. Learn how to make cannabutter with dry ice hash here.
  4. Stir in sugar, eggs, and vanilla extract. If you’re using a stand mixer, mix using low speed until combined.
  5. In a mixing bowl, whisk together cocoa powder, flour, salt, and baking powder. Beat this powder into the sugar, egg, and vanilla mixture until mixed well.
  6. Cook at 350 degrees for 25 minutes. Allow to cool before cutting.


Before cooking pot brownies with marijuana extracts such as dry ice hash, kief, or shatter, you’ll first need to decarboxylate it to activate the THC.

How to decarboxylate dry ice hash kief

After you’ve made your dry ice hash, you’ll need to gently heat the kief to decarboxylate it. Decarboxylation will activate the THC in a way that can be processed by your liver when you eat your pot brownies.

Marijuana flowers and extracts contain a cannabinoid known as THCA. THCA is not psychoactive; this is why eating raw weed flowers won’t get you high. When exposed to heat in the decarboxylation process, THCA will be converted into THC. THC is the cannabinoid in marijuana with the most psychoactive effects.

When smoked or vaporized, marijuana is instantly decarboxylated so THC is made available to your lungs. For edibles, you can easily decarboxylate marijuana, kief, hash, or other concentrates in your oven.

Place dry ice hash on a piece of parchment paper or aluminum foil (never use wax paper) on an oven-safe pan. Spread out the kief so there’s just a thin layer to ensure equal exposure to heat.

Bake kief at 250 degrees for 25 minutes. Kief will brown lightly and have a slightly toasted smell.

Since the THC in kief is fat soluable, you’ll need to melt your kief into butter. View a recipe to make cannabutter from dry ice hash

How to determine the amount of THC in marijuana brownies

How much dry ice hash should I use in weed brownies?

The potency of your weed brownies is determined by how much dry ice hash you use, and how pure your kief is.

Dry ice hash is typically extracted using bags with micron levels of 25, 73, 160, and 220. The smaller the number, the less plant material will be in the hash. 25 and 73 micron kief is great for smoking,You can save that to add to bowls or joints. Using 160 micron hash for pot brownies is a good choice because it’s a little less pure but still doesn’t have the greenish tint of plant material seen in 220 micron hash.

This weed brownie recipe uses 2 grams of 160 micron hash for each 8×8 pan. Use hash  made from high quality strains that max out at 20-25% THC.

The estimated potency of this 160 micron hash should be about 30-33%. Dry ice hash is made from a trim pile very heavy with sugar leaves and finely cut popcorn buds will have a good yield. Good stuff for making cannabutter.

If you follow this recipe and use 2 grams of kief, this means there are 2000 milligrams of kief in the recipe. Since about 33% of that is THC, there is roughly 666 milligrams of THC in the entire brownie recipe.

If you’re trying to make this recipe using other extracts, you can adjust the amount based on the THC content.

How to determine the THC dosage for this weed brownie recipe

Since this recipe used 2 mg of 160 micron kief that has approximately 666 milligrams of THC, here is how you can determine the dosage per brownie:

  • If the pan is cut into 9 brownies (3×3 rows) each will contain 74 mg of THC.
  • If the pan is cut into 12 brownies (4×3 rows) each will contain 55 mg of THC.
  • If the pan is cut into 16 brownies (4×4 rows)  each will contain 41mg of THC.
  • If the pan is cut into 20 brownies (5×4 rows) each will contain 33mg of THC.

Keep in mind that the actual potency of your brownies may vary based on the quality of the hash or concentrate used in your cannabutter. Under-decarboxylated hash will have less potency, as will hash made from less-than-top-quality weed or trim.

How much THC should a person consume?

Determining the effects of edibles such as brownies depends on several factors. Newcomers to edibles should always error on the side of caution. It’s a good idea to take a half dose the first time you try your weed brownies, aim for a dosage around 20-30 mg.

If you eat brownies on an empty stomach, the effects will hit you much faster. NEVER wait 20 minutes and say “I barely feel anything, I better eat another one.” Terrible idea.

Regular users of THC will have a higher tolerance. But don’t be a hardo. If you smoke too much in a sitting, it really isn’t a big deal. If you eat too many edibles, your world will collapse around you. Don’t overdo it. It’s probably best to try your first brownie in the comfort of your own home just to see how it affects you. Better to find you’re passing out within range of your couch vs. being in the middle of a crowded concert.

How to store marijuana brownies

Your best bet to store marijuana brownies is to freeze them. Cut into serving-size pieces and seal in a ziplock bag. That way you can just pull out as much as is needed. They taste great frozen, but you can also microwave them for a few seconds to heat them up like fresh out of the oven.

Always clearly mark that the bag contains THC and the approximate dosage. KEEP OUT OF THE REACH OF CHILDREN! The biggest danger edibles pose is to be unwillingly eaten by children or pets. If you have kids, think twice about storing them anywhere that isn’t locked up away from prying hands and mouths. Be smart.


We’ve tried cooking lots of weed brownies, and this recipe is the best recipe for marijuana brownies we’ve tested. Always decarboxylate the dry ice hash or kief to activate the THC. Melt decarboxylated kief in butter to make cannabutter. Use this cannabutter in the brownie recipe above, making sure to not overcook the brownies. Store in a safe manner.
