Let us talk about space cake in Amsterdam. It is the snack with the biggest stories attached. Every tour guide in this city has one. Ours usually starts the same way: "So my friend ate the whole thing..."
A space cake is a cake, brownie or muffin made with cannabis. It looks innocent. It smells like chocolate and butter, with a little green, grassy note if you sniff hard. It sits under the glass at the coffeeshop counter like a slice of grandma's baking. Then, about two hours later, it hits you like a tram on the Damrak.
We are Oranje Umbrella. We have run tours in Amsterdam since 2012. We have seen more edible mistakes than we can count. This guide is the friendly talk we give every guest before they try edibles in Amsterdam. Read it once and you will have a fun night instead of a long one.
What is space cake, exactly?
Space cake is the local name for any baked good with cannabis inside. It can be a slice of sponge cake, a brownie, a muffin or a cookie. Some shops also sell cannabis chocolates or gummies, but space cake is the classic.
The cannabis is usually cooked into butter or oil first. That butter goes into the batter. When you eat it, your body processes the THC through your stomach and liver. THC is the part of cannabis that gets you high.
Here is the key thing. Eating cannabis is very different from smoking it. When you smoke, you feel it in a few minutes. When you eat it, you might not feel anything for an hour or two. Then it can come on strong, and it can last a long time.
You can only buy space cake legally in licensed coffeeshops. A coffeeshop sells cannabis. A café or koffiehuis (coffee house) sells coffee. Do not buy a "space cake" from a guy on a bridge, or from a souvenir shop with a cartoon leaf in the window. Those lollipops and "cannabis cakes" in tourist shops usually have no THC at all. They are just expensive candy with a hemp label.
How strong is space cake in Amsterdam?
This is the question everyone asks. The honest answer is: you cannot be sure.
Strength varies a lot from shop to shop. It can even vary from one batch to the next in the same shop. Dutch coffeeshops often do not print the exact THC amount on edibles. Back in the US, a legal state dispensary edible usually lists the dose, often 5 or 10 mg of THC. In Amsterdam, you might just get a slice of cake on a napkin.
That is why we treat every space cake as strong until it proves otherwise. Ask the budtender. That is the person behind the counter. Ask how strong it is, how much they would eat as a first-timer, and how long it takes. A good shop will give you a straight answer.
Your own body matters too. How much you weigh, what you ate, how often you use cannabis, and how tired you are all change how strong it feels. Two friends can eat the same piece and have very different nights.
How much space cake should you eat?
Start small. Smaller than you think.
Our rule for first-timers is simple. Eat a quarter. If you are a regular smoker back home, maybe half. Then wrap the rest in a napkin and put it away. Out of sight helps.
Here is why. Space cakes in Amsterdam are often made for experienced users. A whole slice can be far too much for someone who smokes twice a year. You can always eat more later. You can never un-eat it.
The space cake dose plan
- Eat a real meal first. Not just a cake. A proper dinner or lunch. Stamppot, a burger, an Indonesian rijsttafel, whatever. Food in your stomach makes the ride smoother.
- Cut the cake into four pieces. Use a knife or your fingers.
- Eat one piece. One quarter. That is it.
- Check the time. Write it down on your phone.
- Wait at least 1.5 to 2 hours. Do not eat more during this time. This is where people go wrong.
- Check in with yourself. Feeling nothing after two hours? Then you can think about another small piece.
- Plan for a long session. Effects can last 6 hours or more.
How long does space cake take to kick in?
Most people feel space cake in about 30 minutes to 2 hours. Some people take even longer. It depends on your body and on how much food is in your stomach.
This slow start is the number one trap. Here is the story we hear every week. Someone eats a slice at 7 p.m. At 8 p.m. they feel nothing. They say, "This is fake," and eat another one. At 9 p.m. both pieces arrive at once. Now they are lying on the hotel bathroom floor, staring at the tiles and wondering how long tiles have existed.
Do not be that person. Wait two full hours. Go for a walk along the canals. Watch the boats. Eat some fries. Time will pass.
Erik says it best: "In fourteen years, I have never seen anyone get in trouble from waiting too long. I have seen plenty of people get in trouble from not waiting long enough."
How long does a space cake high last?
Longer than you expect. A strong edible can last 6 hours or more. Some people feel a little foggy or sleepy the next morning too.
That changes how you plan your day. Do not eat a space cake at 4 p.m. if you have dinner reservations at 8 p.m. and a canal cruise at 10 p.m. Do not eat one before a museum with a timed ticket. Do not eat one before you have to pack for a flight.
The best time is when you have a free afternoon or evening and a safe place to land. Think of it like a long movie. Clear your schedule, have snacks ready, and know your way home.
What does eating space cake feel like?
Everyone is different. But many people describe it as a "body high." It can feel warm and heavy, like sinking into a soft couch. Music sounds better. Food tastes amazing. Jokes get very, very funny.
A smoke high often feels lighter and shorter. An edible high is often deeper and more physical. It can come in waves. One minute you feel normal, the next minute the lamp in the corner is the most interesting lamp in Europe.
At higher doses, some people feel anxious. Their heart beats fast. They feel dizzy, sleepy or a little paranoid. That is not fun, but it is not dangerous for most healthy adults. It passes.
What to do if you eat too much space cake
So it happened. You or a friend ate too much. Do not panic. Here is what to do.
- Go somewhere calm. Leave the loud bar or the busy street. A quiet room or a bench by the canal works.
- Drink water. Small sips. A dry mouth makes everything feel worse.
- Eat or drink something sugary. Orange juice, cola, a stroopwafel, a candy bar. Sugar helps some people feel better.
- Breathe slowly. In for four, out for four.
- Remind yourself it passes. It always does. You are not going to be high forever.
- Lie down and rest. Sleep is the best fix.
- Stay with a friend. Do not leave someone who feels bad alone.
- Call 112 in a real emergency. 112 is the European emergency number, like 911 in the US or 999 in the UK. If someone faints, cannot breathe well, or has chest pain, call. Doctors and police are there to help, not to arrest you for eating cake.
Two more things. Do not drink alcohol on top of an edible. That is the most common way people get sick. And never drive or ride a bike when you are high. Amsterdam bike lanes are busy and fast. Even walking, stay out of the red bike lanes.
Space cake mistakes we see all the time
After 14 years, we could write a book. Here is the short version.
- Eating the whole slice at once. Cut it into quarters. Please.
- Eating more because "nothing is happening." Wait two hours. Something is happening. It just has not arrived yet.
- Eating on an empty stomach. Food first, cake second.
- Mixing with beer, wine or jenever. Jenever is Dutch gin. It is lovely. It is not lovely with a brownie.
- Mixing with smartshop products. Smartshops sell things like magic truffles, which are legal here. Do not combine them with cannabis. Just do not.
- Buying from street sellers. You have no idea what is in it.
- Eating it right before a flight. Bad idea. And you cannot take edibles home anyway.
Can you take space cake home?
No. Absolutely not.
Taking cannabis out of the Netherlands is a crime. That includes space cake, gummies, chocolate and vapes. A brownie in your carry-on is still cannabis.
For British readers: in the UK, cannabis is a Class B drug. Bringing it into the country is treated seriously. For American readers: federal law still applies at the border, and US Customs does not care that your home state has legal dispensaries. Do not risk your trip, your visa or your record over leftover cake.
Finish it, give it away, or throw it out before you go to Schiphol. If you have a layover and want to see the city, our Schiphol layover private tour guide shows you how. Just skip the space cake on that one.
Where can you eat space cake in Amsterdam?
Inside the coffeeshop is the easiest choice. You can sit, order a mint tea and relax. Remember, coffeeshops cannot sell alcohol.
You can also eat it in a private place where the owner allows it. Many hotels ban cannabis in rooms, so check first. Edibles do not smell like smoke, but hotel rules can still apply.
Be careful about public places. Since May 2023, smoking cannabis on the street in the Red Light District (De Wallen) is banned, with fines. Many other public spots restrict cannabis too. An edible is quieter than a joint, but you still want to be in a calm, safe space when it kicks in. Our guide to smoking weed in Amsterdam's streets covers the rules in detail.

Learn about edibles on a coffeeshop tour
If edibles make you nervous, that is smart. The best way to learn is with someone who knows the shops and the rules.
Our Cannabis Culture & Coffeeshop Etiquette tour spends real time on edibles. We talk about timings, portions and what to do if someone overdoes it. The tour is 2.5 hours and visits two to three licensed coffeeshops. It meets at Beursplein, in front of the Beurs van Berlage on the Damrak, five minutes from Centraal Station.
The rules are simple. The tour is strictly 18+, and we check photo ID. We do not sell, supply or arrange cannabis. Products are not included. Nobody has to consume anything. We ask everyone to eat first, stay hydrated and not mix with alcohol.
Any of our tours can be private — just your group, your date, your pace. Private tours start at €295 excl. VAT for the whole group. Group tours start at €27 per person. For a full overview, see our weed tours in Amsterdam guide.
After the tour, the night is yours. Our concierge desk can book a dinner, a canal cruise or live music. Or keep it easy with a slow walk along the canals. Our Amsterdam canal ring history article is perfect reading for that stroll.
