The main user of the Sweets Memory was Yukiko Sasaki (佐々木 由貴子 Sasaki Yukiko), a maid at the Sonozaki estate with a sweet tooth that she cannot satisfy, only able to be a food critic instead of a pâtissière because she could not cook very well. As her Dopant form, Yukiko kidnapped the top pâtissiers hired by the Sonozaki family by dragging them in her "Sweets Cream" (スイーツクリーム Suītsu Kurīmu) state to a small building on the grounds to make pastries only for her. However, when Akiko attempted to weed out the wrong culprit with her sweets, Yukiko kidnapped her with Mai Asakawa, the daughter of her previous victim. Though intending to kill Akiko for disgracing her love for sweets, the Sweets Dopant is battered by Akiko using a chair before Kamen Rider Double finishes her off with HeatJoker's Joker Grenade Maximum Drive.

Another Sweets Dopant appears in Kamen Rider W Returns's Kamen Rider Eternal entry, transforming from a man named in the credits as the Sweets Man (スイーツの男 Suītsu no Otoko). The character is portrayed by Riku Sanjo (三条 陸 Sanjō Riku), who is the head writer for Kamen Rider W and future Kamen Rider Drive.
The costume design of Sweets Dopant is very similar to Alien Metron, a Kaiju from the Ultraman Series
