Chris Hemsworth is celebrating his birthday with a special surprise from his kids!

In an Instagram post, the Thor actor showed off an extravagant cake that his three little ones baked for his 38th birthday. The sugary creation features a fondant figurine of Chris riding a huge wave on his surfboard.

Of course, the cake is complete with candles and lots of sprinkles.

"Thanks for all the birthday messages! Had an epic day with the family and succeeded in devouring 75% of this awesome cake that my kids made before collapsing into a giant sugary heap of joy," Chris captioned the slideshow of images. "Love you all ! Cheers 🎂 🥳"

Chris shares daughter India, 9, and 7-year-old twin sons Tristan and Sasha with his wife Elsa Pataky. On Wednesday, Pataky celebrated the actor with a sweet carousel of snapshots.

"Happy birthday to my favourite husband ever.😝You mean the world to me. For many more years of laughs and happiness," the actress wrote in the caption of the post.

In honor of Chris' big day, his brothers Liam Hemsworth and Luke Hemsworth couldn't pass up the opportunity to play a few pranks on him.

Liam, 31, wrote "Happy birthday @chrishemsworth" next to a shot of himself and Luke, 40, wrestling under a waterfall instead of posting a picture of Chris.

Chris went along with the joke by writing in the comments, "I'm the best photographer going [sic] round."

Luke also trolled Chris by posting a selfie of himself and Liam while wishing the Avengers: Endgame star a happy birthday.

"Happy birthday brother @chrishemsworth !! Love you mate will remember this trip [to] the Kimberly region for ever. So many memories together," Luke wrote, adding a laughing emoji.
