Jenny Han Celebrates Her Birthday with Jeremiah’s Mirror Glazed Cake from The Summer I Turned Pretty

Warning: The Summer I Turned Pretty spoilers ahead! 

The Summer I Turned Pretty author and showrunner Jenny Han shares Jeremiah Fisher’s love for dark chocolate mirror glaze cake.

In an Instagram post shared on Saturday, Sept. 6, the series creator shared some highlights from her star-studded 45th birthday celebrations.

Photos showed stars including Lauren Graham, Ali Wong and Bill Hader all in attendance — but eagle-eyed TSITP fans online were noticed one small nod to her hit Amazon Prime Video series.

Although some photos from her birthday party showed the novelist and TV producer enjoying a white cake with a crumble and heart-shaped candle on top, another snapshot showed her sticking a fork into a mini dark chocolate cake with a raspberry coulis filling and a mirror glaze on top — just as Jeremiah Fisher, one of the love interests in the teen series, requested for his wedding.

“Ohh so Jenny you are the two tiered mirror glaze with raspberry Stan 😍,” one person commented underneath the post. “Happy birthday!”

“The cake 💯🎉,” another wrote.

“was this the $700 raspberry cocoa cake [Jeremiah] was rambling about?” another joked.

Adapted from Jenny Han’s best-selling book trilogy, The Summer I Turned Pretty follows Belly’s (Lola Tung) love triangle between brothers Conrad (Christopher Briney) and Jeremiah (Gavin Casalegno).

In one viral episode from the show’s third and last season, the engaged Belly and Jeremiah quarrel over the details for their wedding, arguing over which elements to spend their tight budget on — including one dilemma is at a bakery.

Belly asks the baker for “a two-tier dark chocolate cake with a raspberry coulis filling and a mirror glaze on top” because Jeremiah “had his heart set on” it. She is quoted $750 for the sweet, which is out of their meager budget.

In the episode, Belly calls Jeremiah with a new plan, explaining that they can still get a cake from his “preferred bakery,” but it would be a single-tiered milk chocolate cake with raspberry coulis.

“Belly, cacao is the bean. It’s what the chocolate is made of. Look, the whole flavor profile depends on the bitterness of the dark chocolate and the sweet tartness of the raspberry,” he replies stubbornly. “The cake is my one thing, and you said each of us get one thing.”

Belly pleads with him to be “realistic,” and Jeremiah responds, “Well, then I’ll put it on a card and pay it off later.”

The cake was fuel for fans who debate whether Belly will go Team Jeremiah vs. Team Conrad debate — though viewers who are up to date on the series know that she and Jeremiah called off their wedding.

Han, who wrote the trilogy of books the Prime Video series is based on as well as hits like To All The Boys I Loved Before, gave some rare insight into her thoughts on whether Belly will choose Jeremiah, or Conrad.

After the host suggested that Belly has to choose Jeremiah or Conrad, Han interjected. “Well, she doesn’t,” she said. “I don’t think she has to choose one.” during an interview on the Wild Card with Rachel Martin podcast.

Han has previously teased that the series’ ending is going to “surprise” fans — even those who’ve read the books — and that it will leave people “devastated and heartbroken,” because that’s how a “successful love triangle” ends.

“That is the tragedy of the story, is that no matter what, you’re going to be hurting somebody that you love dearly,” she continued.

Despite the tragedy, Han said fans “will still feel hope” at the end of the series. “I hope so.”

New episodes of The Summer I Turned Pretty drop on Wednesdays at 12 a.m. PT/3 a.m. ET on Prime Video.
