Bookish Baking #10: Ambrosia Squares and Nectar (Percy Jackson)

I love Percy Jackson. And with how much I loved the Blue Cookies recipe, I thought another iconic PJO recipe was in order.

My past recipes include:

The healing god food used in emergencies, when demigods are seriously hurt. Ambrosia will cure almost any injury, although too much can make a demigod feverish and kills mortals. At Camp Half-Blood ambrosia comes in squares in sealed bags. On Mount Olympus you can buy it on a stick.

Ambrosia Squares

(Sort of a combo cream cheese square and Blondie recipe)


  • 1 cup butter, melted
  • 1 (8 ounce) package cream cheese, softened
  • 2 eggs
  • 1 ½ tbps lemon juice
  • 1 tbsp flour
  • 3 1/2 cups confectioners’ sugar
  • 1/2 cup brown sugar
  • 2 1/4 cups all-purpose flour
  • 3/4 teaspoon baking soda
  • 1/2 teaspoon fine salt
  • 1 teaspoon vanilla extract
  • 1 1/2 cups butterscotch, semisweet chocolate, peanut butter, or white chocolate chips, optional – I think butterscotch works best though.


  1. Preheat the oven to 375 degrees F.
  2. Grease and flour a baking dish.
  3. Melt butter in a bowl, mix together cream cheese, 2 eggs, lemon juice, sugar and vanilla, pour in butter.
  4. In another bowl, whisk the flour, baking soda, and salt together. Add the flour mixture a bit at a time to the other mixture and mix until smooth.
  5. Fold in the chips, as desired.
  6. Spoon batter into baking dish. Bake for about 15 minutes at 375F, reduce to 300F and bake for about another 20-25 minutes, until a toothpick can be removed cleanly.
  7. Cool completely and cut into squares.

“Don’t strain yourself,” Grover said. “Here.” He helped me hold my glass and put the straw to my lips. 

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. Drinking it, my whole body felt warm and good, full of energy. My grief didn’t go away, but I felt as if my mom had just brushed her hand against my cheek, given me a cookie the way she used to when I was small, and told me everything was going to be okay.

Percy Jackson’s Liquid Chocolate Chip Cookies


  • 1 1/2 tablespoon butter
  • 2 tablespoons flour
  • 1/4 tsp cornstarch
  • 1 ½ cups milk
  • 3-4 tablespoons sugar, to taste
  • 1 teaspoon vanilla extract
  • ¼ teaspoon baking soda
  • pinch of salt
  • 3-4 tablespoons chocolate chips (or basically what you desire really)
  • Blue food coloring


  1. Melt butter in a saucepan on medium-low heat. Stir in flour and allow to cook for 3-5 minutes.
  2. Whisk in the rest of the ingredients, save the the chips, and add the food dye last, until desired coloring. Stirring as you add.
  3. Bring to a low boil and cook for 10-15 minutes, stirring frequently.
  4. Remove from stove when consistency is as desired (will thicken when cooled).
  5. When completely cooled, stir in the chocolate chips.

I hope you guys enjoyed this recipe! Let me know if you try it out, and if your enjoying this feature in general/have any requests!
