Laurel also left a note with several cake puns next to it, explaining the truth. She posted a picture of both the cake and the note on her Tumblr.
"I'm gay," reads the note. "I've wanted to tell you for a long time. I thought doing it this way would be a piece of cake.
"I hope you still love me. I mean, it's hard not to love someone who baked you a cake.
"All my friends know and still love me. Your acceptance would be the icing on the cake."
Laurel later updated her Tumblr with her parents' reactions.
She posted: "My dad saw the cake and came into my room and hugged me and laughed. He said he loved me and the cake and the letter and everything was perfect."
Lauren then added: "My mum saw it and cried of happiness. We hugged and cried together. Then, we all ate the cake and talked. I am very lucky to have such supporting parents."
