Warning: You will want to nom all of the incredible-looking confections in Katy Perry's lyric video for her song 'Birthday.' Just letting you know in advance.

Perry puts on the chef's hat in this colorful video, baking decadent desserts like French macarons, ornate batches of cupcakes, and multiple kinds of cakes, including a six-layer rainbow cake, a Hello Kitty cake, a Rubik's Cube cake and even a cake modeled perfectly after a hamburger. And of course, they all spell out the lyrics to the sweet but sexy tune against a shimmering backdrop of sparkling bronze streamers. (Would you expect anything less from the bold singer?)

While you can't see anything but Perry's hands for the majority of the vid, her vivid, blinged out nails go perfectly with the video's theme and almost look like brightly-colored sprinkles themselves.

Watch the sugar-filled lyric video for 'Birthday' above -- but don't say we didn't warn you: you'll want to eat everything!
