It was emotional celebration when Drew Barrymore's daughters surprised her on her talk show with multiple custom cakes in honor of her 50th birthday.

The Drew Barrymore Show celebrated its host's milestone birthday, which lands February 22, with a special episode the day prior that featured Flour Shop founder and baker Amirah Kassem unveiling cakes designed by Barrymore's two daughters, Olive, 12, and Frankie, 10, whom she shares with ex-husband Will Kopelman, per People.

"I wanted to bring in two of the very best cake designers ever, and your girls actually designed these themselves," Kassem said, showing off the two confections, Olive's colorful with a rainbow pattern and stick figure portrait and Frankie's white-and-pink striped and covered in flowers.

The 50 First Dates actress was left speechless as she stared down at the cakes her daughters designed just for her, but the surprises didn't stop there as Kassem revealed the girls had also written letters to their mom. An already teary-eye Barrymore held back the waterworks for as long as she could before breaking down while reading each heartfelt note.

"Dearest mommy, happy birthday," she read from her youngest's letter. "Can you believe it? 50 years of being the most fabulous, kindest person on earth, and 12 years of being the most caring, loving mom, I love you so much. Best birthday wishes, Frankie."

Olive's message was just as emotional as her sister's as she told her mom, "Not in my 12 years of living life have I found a mother as wonderful as you," she wrote, hilariously adding, "the search goes on."

Barrymore previously shared her excitement for turning 50, admitting that she has "no issues with aging" and that the milestone "[couldn't] come soon enough.

Happy birthday, Drew!
