Simon's Birthday Cake - A Firefly Recipe

“Couldn’t get a hold of no flour, so it’s mostly protein. In fact, it’s pretty much what we just had for dinner. But I tried to get the frosting as chocolate-y tasting as possible.”

-Kaylee, Firefly

It’s Simon’s birthday cake! In the Firefly episode, “Out of Gas,” Kaylee makes a birthday cake for Simon. It’s a sweet moment when she tries to make the day special for him even though she couldn’t find the proper birthday cake ingredients or real birthday candles.

In recreating this cake, I didn’t want to go fully authentic because I did want the cake to actually taste good, and let’s be honest, the cake Kaylee describes doesn’t sound like the most appetizing thing in the ‘Verse. But I took elements from the description to create a cake that I think fits the bill pretty well.

When thinking about protein to use in a cake, I immediately decided that peanut butter was the way to go. I adapted this peanut butter cake recipe for the cake layers. Since the frosting seems to be a mix of protein and chocolate, I went with this Nutella buttercream frosting. The protein from the hazelnuts is minimal, but it’s there.

This cake turned out awesome, I thought! The frosting was particularly yummy. As Kaylee says to Simon, “I hope you like it.”

For the cake

  1. Preheat oven to 350 degrees F, and grease two round cake tins.
  2. Stir together the flour, baking powder, baking soda, and salt in a medium bowl, and set aside.
  3. In a separate bowl, stir together the oil, peanut butter, sugar, eggs, and vanilla.
  4. Add the flour and milk, alternating between the two, and stir until just incorporated.
  5. Divide the batter between the two pans, and bake for about 25 minutes.
  6. Allow the cake to cool before attempting to frost it.

For the frosting

  1. Stir together the butter, powdered sugar, and Nutella.
  2. Slowly beat in the milk until the frosting reaches the desired consistency. You may need a little more or a little less than called for. If you accidentally overdo it and the frosting becomes too runny, just add more powdered sugar.

This cake isn’t fancy, but it sure tastes good!

#FireflyFeast : Celebrating the Food of Firefly and Serenity

I am so excited to be hosting Fandom Foodies this month! Fandom Foodies is a group of people who enjoy cooking yummy foods based off their favorite fandoms. Every month, there’s a different fandom theme. For this month’s theme, I chose Firefly!

For those of you who may not know, Firefly was a short-lived TV show in the early 2000s. It’s a sci-fi western (yeah, you read that right!) and it was cancelled after only one season. It quickly gained a cult following, though, and that fanbase continues to this day. In 2005, they made a movie sequel to the show to give fans “closure”. This movie was called Serenity, and it is equally awesome! If you’ve never seen Firefly or Serenity, I highly recommend you watch them both.

Below is a link-up where you can submit your recipes inspired by Firefly or Serenity. If you’re sharing on social media, use #FireflyFeast so we can find your recipe 🙂 Keep checking back here all month to see all the new recipes added. I’ll be cooking up a few myself. Can’t wait!


Good food is meant to be shared!
