A space cake (or cannabis cake) is precisely what it sounds like: a delicious cake infused with cannabis. Available in dispensaries nationwide, space cakes have become immensely popular for cannabis consumers with a sweet tooth. Space cakes are delicious, discreet vehicles used to reach an out-of-this-world high (pun 100% intended).
While many space cake recipes exist, each boils down to combining the same materials. A space cake is simply a cake recipe of the user’s choice made with cannabutter or another cannabis-infused fat such as coconut oil.

Here we’ll break down a popular space cake recipe so you can whip up the tasty cannabis treat in the comfort of your own home. But first, let’s answer some common questions about dosing.
How long do the effects of a space cake last?
Space cakes are edibles, which means the THC takes a lot longer to kick in than with other cannabis consumption methods. It’s always smart to start with a small serving and wait for one to two hours to evaluate the high’s effects before taking more. Remember: you can always eat more, but you can’t eat less.
Why do edible highs end up feeling more potent than vaping or smoking highs? Well, when you ingest cannabis, the THC in the edible converts to 11-hydroxy-THC in the liver, which is notably more potent. Edibles take longer to process, too, as the THC has to travel through your digestive system to kick in.
How do You calculate the dose per serving?
To find out the dose of one serving of your space cake, you need to do a little math. Start by finding out the THC percentage of the flower you’re using to bake with. So, for example, if you start with 1 g of flower containing 20% THC, that would leave you with 200 mg of THC total. After decarbing the flower, you’ll lose roughly 10% of that THC (200 x 0.9), leaving you with 180 mg of THC total. Following the extraction in oil or butter where you lose another 40% of the THC (180 x 0.6), you will have 108 mg of THC in that oil.

The decarboxylation process:
- The heat activation of THC prior to ingestion. In other words, if someone were to eat a quarter-ounce of weed at once, they wouldn’t feel the effects because no decarboxylation process occurred. When marijuana is smoked, the heat igniting the plant matter causes decarboxylation to occur and the activated THC is ingested on the spot.
- In cases of THC consumed in the edible form, decarboxylation needs to occur before ingestion for any effects to be truly felt. Scarfing down a decarbed quarter-ounce of weed would result in seriously potent effects (not recommended). Instead, this quarter ounce worth of activated THC is processed into a solution that can be used in place of butter, or oil, in many common recipes. Either used in a weed cake recipe, or an equally inviting pastry, the decarbed marijuana is now primed for THC transfer into the kitchen-ready butter or oil forms.
- Activating THC so it can be operative once ingested is important, but so is processing the decarbed plant matter into something that’s viable in the kitchen. At the heart of the cannabis cake recipe is preparing the cannabutter. These hypothetical wedding caterers would most likely have had cannabutter stored on deck, prepped ahead of time so any weed cake recipe could be handled without extensive prep work.

Final Thoughts on How to Make a Weed Cake:

- Properly decarbing your weed will ensure that your weed cake recipe turns out with a decent potency.

THC vs CBD edibles
THC edibles are wonderful for both medicinal and recreational purposes, as they can provide an intoxicating sense of euphoria alongside strong painkilling qualities. They can also help with appetite, system regulation, and mood leveling, which is the reason why they are one of the most popular cannabis products on the market today.
CBD edibles offer most of the very same benefits without the drawbacks that can come from the psychoactive nature of THC. That means patients can often achieve relief without feeling sedated or groggy.
No matter the type of edibles chosen, it is always a good idea, to begin with, a low dose and slowly works your way up until you’ve found the most suitable potency. That is especially true with CBD edibles, as they will remain in your system long term, which means that eventually, a lower dose can be taken and will achieve the very same benefits.
Ate weed space cake while having ADHD and on medication with antidepresives. Worst decision ever. People, be save and don’t mix different drugs (or consume drugs while you are medicated). Feels stupid to advise but when it happens you wish you had seen this before.
