Carrie Underwood celebrated her son Isaiah turning "six whole years old" over the weekend with an epic cake.

The powerhouse singer took to Instagram to share a photo of the awe-inspiring Power Rangers cake her friend and professional baker, Ivey Childers, made for Isaiah.

The three-layer cake features a red Power Rangers figurine on the top tier adorned by a pair of swords, ninja power stars and shields made of frosting.

Isaiah even got a "happy birthday" shout-out from the official Power Rangers account.

"Isaiah, you are kind, funny, smart, the best big brother, a lover of cuddles and crafts and you have the biggest heart and the best imagination!" Underwood wrote alongside another photo of her hugging her son.

"You love to make people feel good and you especially love to make them laugh!" she added. "God has given you so many gifts and every day, I thank Him that I get to be your mom! I love you, Monkey! Happy birthday!"

Fans flooded the comments section of the post with celebratory messages. Underwood's husband, Mike Fisher, also shared a sweet tribute for the occasion.

"Happy 6th birthday Isaiah!" he wrote. "I’m blessed to be your dad and proud of how you love Jesus and others so well! And please stop growing up so fast!!"

Isaiah is Underwood's and Fisher's oldest child; his brother Jacob is 2.
