Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be stored inside a locker in Site-16. Said locker must be monitored by security cameras at all times in order to prevent attempts at stealing or creating copies of the item. No copy of SCP-XXXX must be made without express permission from the site director.
Any leftovers of SCP-XXXX-1 that remains after tests must be disposed of via incineration.
In order to prevent the possibility of SCP-XXXX being used for personal gain all researchers assigned to it must be in a stable relationship. In case of a breakup or aparision of domestic problems said researcher will be given a Class C amnestic in order to forget SCP-XXXX's exact measurements and then transferred to a different project.
All personnel assigned to SCP-XXXX must go through psychological analysis every four months. Suspicion of romantic interest for someone who isn't that person's current partner will lead to reassignment to another project, as well as being forced to forget SCP-XXXX’s measurements.
Description: SCP-XXXX is a piece of paper containing a recipe for a chocolate cake. The paper doesn't show any anomalous property and any copy of the recipe will be regarded as an instance of SCP-XXXX.
The recipe starts with the title “Lana’s Lovely chocolate cake” written in pink ink, followed by a list of ingredients, which are, in order: flour, milk, eggs, sugar, salt, cinnamon, vanilla extract, buttermilk, cocoa powder, and baking soda. Each ingredient is followed by the exact brand required and measurements detailing the exact number of grains in the case of the dry ingredients or [drops] in the case of the wet ones. Under the ingredient list are the steps for the preparation of the cake, also detailed with millimetric precision.
Finally, there's a list of substitutions for a vegan cake and a gluten free cake, also accompanied by the exact brands and measurements.
When the recipe is correctly followed a chocolate cake designated as SCP-XXXX-1 will be created. The cakes made by following with the regular recipe and the ones using the substitutions have the same effect, and are both designated as instances of SCP-XXXX-1. Any failure at following the exact recipe will create a regular chocolate cake with no special effects.
When SCP-XXXX-1 is given as a gift to someone and ingested, the receiver will instantly fall in love with the one who gave them the cake, independent if the one giving it was the one who made it. The feelings of the receiving party are always romantic in nature, and the effect will manifest independent of sexual or romantic preferences.
If SCP-XXXX-1 is acquired in a way different than a gift, such as stealing or purchasing it, the effects won't manifest until that person gives it to someone else. If someone who acquired SCP-XXXX-1 as a gift decides to give a part of it to another person the effects won't show up.
Any portion of the SCP-XXXX-1 will conserve the anomalous effects, and the feelings expressed by the receiver will be the same independent of the quantity of cake eaten. Eating more SCP-XXXX-1 given by the same person won't produce any new effect. If an already affected subject is given a part of SCP-XXXX-1 by someone new they will develop the same feelings towards the new party without losing those present for the previous one, and won't be happy until achieving a romantic relationship with both people at the same time. There doesn't seem to exist an upper limit to how many people can a person be made to hold feelings for.
There's a level of variety in the way the feelings will manifest, but in general the subject tends to express an extreme level of devotion towards the one who gave them SCP-XXXX-1 and a desire to pursue a romantic relationship with said person.
If the subject experiences a rejection by the person they're in love with they will continue to romantically pursue them in hopes to change their mind. While these pursues can lead them to take extreme actions, such as significant lose of material possessions or severing ties with friends and family, subjects usually will draw the line at causing physical harm to themselves or other people, unless they already had violent tendencies before eating SCP-XXXX-1. No subject has ever attempted to physically harm the person they're in love with.
If the subject is forcefully feed with SCP-XXXX-1 or threatened to eat it the effects won't manifest, as well as if they aren't aware the cake is a gift. It is possible however for the effects to manifest without the receiver knowing who gave them the cake, such as leaving it for then with a note stating the cake is a gift. In this case the subject will express confusion and an overwhelming desire to meet whoever sent them the cake, and won't be fooled if introduced to someone different from the person who left the cake, stating that "It doesn't feel right". The effects will also show up if the receiver isn't aware of what they're eating, such as feeding them while blindfolded or mixing a part of SCP-XXXX-1 with another food.
While the feelings created by ingesting SCP-XXXX-1 don't seem to diminish over time, it's worth keeping in mind the oldest known use of it dates from less than 10 years ago, and as such whether or not the effect wears over time is still inconclusive.
Erasing the memory of eating the cake with amnestics won't do anything to eliminate the effects, however, it is possible to force the subject to forget who it is they were in love with, in which case most of them express “feeling like something is missing”, and if not introduced again to that person will usually develop symptoms of depression, often leading to suicide.
Recovery
SCP-XXXX was recovered after the online store Lana's Sweet Bakery exploited in popularity in 2017. The store sold different baked goods across USA and Canada, some of which were instances of SCP-XXXX-1, referred by the site as “a lovely chocolate cake that will help you get the heart of that special someone.”
After discovering this website the foundation followed the I.P to an abandoned house in [], Texas, residence of Lana [], currently disappeared. SCP-XXXX was found inside a drawer in the kitchen, as well as several other recipes of which SCP-XXXX seems to be the only one displaying anomalous properties. After retrieving SCP-XXXX, the website was replaced by a simple message stating “I’m sorry everyone but I'm closing the store. See you soon.” which stayed for three days before the site went down.
Since the effects of SCP-XXXX-1 can't be reversed and victims are unlikely to commit real harm to others unless there were already violent tendencies, the foundation decided not to interfere with those affected by these instances of SCP-XXXX-1 sold by the store. Several recurrent clients were interviewed and Class C amnestic were administered in order to make them forget ever buying anything from the website.
