If you already have cannabis butter made, you can skip to step five.

  1. Decarboxylate Cannabis: Preheat the oven to 240 degrees F(115 °C). Weigh out the desired amount of cannabis. Use your judgement and experience level as a guide. Edibles can often end up being too strong to handle, even for those with a high tolerance. Use a potency calculator or see “Space Cake Tips” below for guidance.
  2. After weighing, use a grinder, scissors, or your hands to break up the weed and spread it out evenly on a parchment-lined baking sheet. Toast in the oven for 40 minutes, stirring every ten minutes or so. This process is called decarboxylation, which converts the non-psychoactive THCA to the psychoactive cannabinoid, THC.
  3. Infuse the Butter: Next, you’ll need to infuse the THC into a fat to make it easier for your body to absorb. Melt your butter or butter substitute in a medium-sized saucepan over low heat. Add your decarboxylated cannabis and one cup of water. Stir to combine. The water will help prevent the cannabutter from scorching. Continue to simmer this mixture on very low for three hours, stirring regularly. Set a timer and don’t leave the stove unattended.
  4. Strain and Cool: When time is up, place a coffee filter or cheesecloth over the opening of your glass container and carefully strain out your mixture. Discard the plant matter. Place your butter and water mixture in the refrigerator to set up. As the mixture cools, the water will sink to the bottom and the cannabis-infused oil will float. When the butter becomes firm, use a knife to poke a small hole and pour out the water. The more firm the butter, the easier this step will be. This process, while somewhat lengthy, will yield highly potent cannabutter that you can use for space cakes or a wide range of other edibles.
  5. Prep: Preheat oven to 350 degrees F(175 °C) . Grease and flour your baking pan or insert cupcake papers. Use a microwave or saucepan to melt the cannabutter.
  6. Combine ingredients: In a large mixing bowl or electric mixer, combine all ingredients and blend until smooth and well combined. Add any optional flavoring at this time. 
  7. Bake: Pour batter into your prepared baking or cupcake pan. If making cupcakes, consider using a measuring cup to ensure equal servings.
  8. Check to see if the cupcakes are fully cooked after 15 minutes. If using a 9 x 9 pan, check after about 20 minutes. Insert a toothpick straight down into the center of the cake. If the toothpick comes out clean, remove the space cake from the oven. If not, continue to bake for three more minutes and check again.
  9. Chill out: Allow the space cakes or space cupcakes to cool in the pan for 20 minutes before turning out. Allow the cake to cool completely before cutting.

Space Cake Tips

Dose carefully. Edibles take much longer to kick in than smoking or vaping cannabis. It’s wise to start with a small serving and wait an hour or more to evaluate the effects before increasing your serving size. 

You can easily calculate the amount of THC per serving by multiplying the THC percentage by the weight of cannabis in milligrams and dividing by the number of servings per batch. For example, if you use 5 grams(5,000mg) of cannabis with a THC content of 20%(.2) to make a space cake, the entire cake would contain approximately 1000mg of THC.

If you cut the cake into eighths, each piece would contain roughly 125mg THC(5,000 ✕ 0.2 ÷ 8). If you cut it into 12 pieces, each would contain closer to 83mg. If being incredibly stoned is your goal, this will most likely do the trick. If you’re unaccustomed to edibles or sensitive to THC, use less weed in your cannabutter. 

Store in the freezer. If you’re not planning on eating an entire space cake, place your leftovers in an airtight container and store in the freezer for up to a month! Remember to CLEARLY LABEL your space cakes, especially if you have roommates. Keep well out of reach of pets and little ones.

Easier space cakes: While space cakes are already an easy recipe that tastes great, you can make it even easier by using a store-bought cake mix. Just make sure the recipe calls for butter or oil. Simply make your cannabutter using the steps above and then follow the instructions on the back of the box.
