Blue Chocolate Chip Cookies Recipe
These easy blue chocolate chip cookies are made with white cake mix, white chocolate chips and blue food coloring.
They’re soft, chewy and simple enough to make when you need a colorful dessert without decorating individual cookies.
Serve this cookie recipe for a Percy Jackson party, a blue-themed birthday, a baby shower or a school color celebration.
Gel food coloring produces the brightest shade without thinning the cookie dough, and you can adjust the amount to create anything from pale blue to a deeper royal blue.

In the Percy Jackson series, Sally Jackson makes Percy blue food — including blue chocolate chip cookies — as a running joke and comfort tradition between them. It’s become a popular recipe for fans to recreate.
Percy’s favorite food is anything blue, especially his mom Sally’s blue chocolate chip cookies and blue candy — a nod to his stepfather Gabe insisting blue food didn’t exist.
No — the food coloring doesn’t affect the flavor. These taste like a classic chocolate chip cookie; only the color changes.
Tips for Perfect Blue Chocolate Chip Cookies
- This recipe uses a boxed cake mix as the base, which is what makes it so quick to pull together — no measuring out flour, baking soda, or salt separately.
- If you’re a fan of easy cake-mix desserts, this method works well for other fun colors too (just swap the food coloring).
- Some cake mixes have a yellow undertone that can pull your blue toward green or teal. If that happens, add a touch of purple gel coloring along with the blue to counteract it.
- Use gel, not liquid — it gives a more saturated color without thinning the dough.
- The color deepens slightly as the cookies bake, so stop just shy of your target shade.
