There are no traditional aspiring-rationalist foods that I know of. Here's a potential candidate for one. I started with a friend's family recipe and adjusted it to be vegan and slightly more thematic.

The white mini chocolate chips symbolize humanity (the light in the world) in the darkness of the universe (the bitter chocolate cookie). The dried cherries can be... nebulae.

Makes around 12 large cookies.

Ingredients

• 1 Tbsp instant espresso powder
• 1 Tbsp boiling water
• 133g (5/8c) coconut oil
• 176g (1c packed) brown sugar
• 80g (1/4c) mashed banana
• 1/4 tsp vanilla extract
• 120g (1c) flour
• 90g (3/4c)  unsweeted cocoa powder
• 1 tsp baking soda
• 2 tsp baking powder
• 1/4 tsp salt
• 100g (3.75oz, 3/4c) chopped sweetened dried cherries
• 80g (3oz, 1/2c) mini white chocolate chips (vegan)

Directions

Preheat oven to 350 degrees and line baking sheets with parchment paper.

Mix instant espresso powder and water in a small bowl, and reserve.

Cream the coconut oil, then add brown sugar and cream together. Add mashed banana and vanilla and beat until thoroughly combined. Add reserved espresso/water mixture and beat until combined.

In a separate bowl, mix the flour, cocoa powder, baking soda, baking powder, and salt, then combine with the wet ingredients. (Or if you're lazy like me, put them on top of the wet ingredients and mix the dry ingredients with a fork before mixing fully.) Fully combine until a dough forms.

Mix in chopped dried cherries and mini white chocolate chips.

Form dough into flattened balls and place on cookie sheets. Bake for about 13 minutes.

Remove from oven and cool for 10 minutes before transferring cookies to a wire rack to cool completely.

These taste slightly better the next day; they get a bit chewier.
