Blue chocolate chip cookies | Percy Jackson

I recoiled at the taste, because I was expecting apple juice. It wasn’t that at all. It was chocolate-chip cookies. Liquid cookies. And not just any cookies – my mom’s homemade blue chocolate-chip cookies, buttery and hot, with the chips still melting.

-Percy Jackson and the Lightning Thief, Rick Riordan
While it may not be in liquid form, these delicious blue chocolate chip cookies are what I imagine Percy Jackson's elixir to taste like. Super quick and easy to make as well!

What looks like apple juice ends up tasting of Percy Jackson’s mom’s blue chocolate chip cookies. The taste of her warm buttery recipes is Percy’s elixir drink, replenishing his energy and helping heal injuries.

Instead of trying to tackle making a drink that tastes like buttery choc chip cookies and looks like yellow liquid(!!), I’m going to tackle making warm, buttery cookies instead. Which might seem simple, but the ‘right’ type of chocolate chip cookie can be difficult to get right. Not because the recipe can’t be made, but because people have such specific thoughts on what a good chocolate chip cookie should taste like. Is it soft? Crunchy? Both? Fluffy? Flat? Made with white sugar? Brown sugar? Do you chill them or make a batch that is baked straight away? With one type of choc chip, or multiple types?

See my dilemma?

I ended up baking up a batch first as a ‘ test cookie’ to compare my recipes to. Since the recipe was practically the same on the Nestle choc chip bag and the Cadbury one, I used their recipe as my sample. While delicious, because Percy’s mom makes hers taste buttery, I needed to adjust to get the taste right. I was hoping for a more sugar cookie taste, but I think it’ll need more tweaks to get the balance. In the end I added an extra egg to make them fluffier, increased the butter and added a mix of brown and white sugar.

Blue chocolate chip cookies | Percy Jackson

  • Author: Bryton Taylor
  • Total Time: 40 minutes
  • Yield: 12 1x


Units Scale
  • 175g butter, softened to room temperature
  • 1/2 cup brown sugar
  • 1/4 cup white sugar
  • 2 eggs
  • blue food dye
  • 2 cups plain flour
  • 1 cup chocolate chip pieces


  1. Start by making sure your ingredients are at room temperature.
  2. Preheat your oven to 160C.
  3. In a mixer, cream together the butter, sugars, and eggs.
  4. Add in a splash of blue food dye. If you add it to just the wet ingredients, you’ll get a nice blue consistency through your cookies.
  5. Stir in the flour, then stir in the choc chip pieces.
  6. Scoop a tablespoon onto a baking paper-lined tray. No need to press them down, they’ll flat themselves.
  7. If I’m wanting the cookies to look ‘pretty’ and Instagram or Pinterest worthy, I’ll press a few extra chocolate chip pieces onto the top of the cookie dough ball.
  8. Bake for ~15 minutes (depending on your oven).
  9. Remove from oven and let cool before eating.
  • Prep Time: 10 minutes

    1. Hi Laura, you’re reading correctly, I didn’t put baking soda or powder in these. How you like your chocolate chip cookie, I’ve found, is a very personal thing. If you want a fluffier cookie, feel free to add. However, this recipe is for a denser cookie.

  2. Just wondering, how many cookies does this recipe make? In the video, it shows 4 cookies, but it’s not actually listed anywhere.
    Thanks in advance! 🙂
