Cannabis-Infused Heavy Cream (Canna-Cream)

Cannabis-infused cream, or canna-cream, is an easy way to infuse most foods that require cream like soups, ice creams, and it can even be added to coffee! Canna-Cream can easily be made at home using these simple steps.

Preparation time: 50 minutes
Cooking time: 1 hour Yield: 1 cup


  • Double boiler or pot and mason jar
  • Cheese cloth or fine sieve
  • Large bowl


  • 1 cup Heavy cream
  • 7 grams of decarboxylated cannabis


  1. With any recipe involving cannabis, it is always important to decarboxylate or “decarb” your cannabis before cooking or baking with it. To decarboxylate your cannabis, preheat your oven to 115°C (240°F). Grind cannabis, then spread on a baking sheet in a single layer, and tent with tinfoil. Bake for 40-50 minutes, until the cannabis appears dry and brown with a crumbly consistency.

  2. Heat heavy cream and decarboxylated cannabis in a double boiler on medium heat. If you don’t have a double boiler, pour heavy cream and decarboxylated cannabis into a mason jar and place in boiling water, with about ¾ of the jar immersed.

  3. Let simmer for at least one hour, stirring occasionally if you are using a double boiler. If you are using the mason jar technique, just let the water around the mason jar boil.

  4. Remove heavy cream and cannabis mixture from heat and let cool completely.

  5. Once cooled, strain through a cheese cloth or fine sieve into a large bowl to separate the cream from the cannabis.

  6. Store in refrigerator for 7-10 days.

Edible Calculations

  1. Calculate the total milligrams of THC or CBD in one gram of dried cannabis, for JWC’s Dark Helmet GE, which tests at ~20% THC, this equals 200mg.

1g = 1000mg 0.20 x 1000mg = ~200mg THC/g

  1. Calculate the total amount of THC or CBD in the infused cream that you are making. To do this, multiply the milligrams of THC and/or CBD per gram by the total grams you are using.

200mg THC x 7 grams = ~ 1,400 total mg of THC

  1. You can determine the amount of THC in one tablespoon of canna-cream by dividing the total mg in the cream by the number of tablespoons you have produced. There are 16 tablespoons in one cup.

~1.400mg THC ÷ 16 = 87mg/THC

  1. Determine the amount of THC you would like per serving. In this case, we are aiming for ~10mgTHC per serving of ¼ cup whipped cream. 1 tablespoon of canna-cream combined with a scant 1 cup of cream would contain 87mg THC and make 8 servings. Therefore, each serving would contain ~10.9mg/THC. You can increase of decrease the amount of THC per serving by adjusting the amount of canna-cream used.

These calculations are approximate. Always consume responsibly.

Remember, it can take anywhere between 60-180 minutes for you to begin to feel the effects of ingested cannabis and the effects may be felt up to 8+ hours after consumption. If you are unsure how cannabis may affect you, we recommend referring to Health Canada’s consumer information here. Always consume responsibly.


*With any cannabis-infused edibles, the general rule is to start with a low amount, and only increase slowly. Here at JWC, we would like to remind you that determining your dosage should be based on the information provided to you on your medical document. Do not change your dosage without first consulting with your healthcare provider. As always, make sure that your edibles are properly labelled and are stored out of reach of children and pets.

When working with edible, cannabis-infused products, try to understand and maintain the ratios between the amount of cannabis and the butter or oil being infused. If your cannabis butter or oil is potent, consider reducing the amount used in your recipe by using a mix of infused and regular butter.
