Remember this?

It’s the Lego Bionicle “thing” my son wanted his birthday cake to look like. You know I’m always up for a birthday cake challenge, right? (Just for the record, it’s called a Thornax.)
Well, I’m pleased to report that I came, I saw, I baked that cake!
The frosting job wasn’t the best, but I blame the virus I’ve been fighting for the last few weeks. And you know what? My kid didn’t complain. He was really pleased — and really polite, too.
To make this Lego Bionicle Thornax cake, you’ll need:

1 boxed cake mix, prepared according to package directions
Wilton sports ball cake pan (or two same sized bowls to bake in)*
1 can of prepared frosting
a small wide mouthed jar with lid (or some other container to hold the Tornax off your serving plate)
8 sugar cones
powdered sugar

Bake cake according to the directions included with the sports ball cake pan. Remove from pans and cool completely. Tint frosting the desired shade of yellow with the paste food coloring. “Glue” the jar to your serving plate with a little frosting. Frost one half of the cake and place it flat side up on the jar. Frost the flat side. Place second half of the cake flat side down on the first half. Frost the entire ball. Frost the sugar cones and place them about the cake at equal intervals, four on each half of the cake as shown. Use toothpicks to support the cones on the top half. Cones on the bottom half will rest lightly on your serving tray. Roll out fondant on a surface sprinkled lightly with powdered sugar. Cut a 1-inch strip of fondant to place around the “equator” of the ball.

*This sports ball cake pan also works well if you’re making a Pokeball cake for a Pokemon fan.

    It turned out great!

    By the way, I adore that you mentioned an alternative to buying a specialty cake pan. I am so often tempted to buy those, but finding other ways is much more frugal!

    My middle son just put in an order to me for this cake for his birthday. I knew it was a Bionicle piece when you gave the sneak peek the other day. It's fun to be a momma of boys!

  8. Thank you so much for this article. My son just had his 6th birthday and we did a Bionicle theme. My wife and I took a stab a copying your recipe and it didn’t come out too bad. We couldn’t get black color for the fondant so we went with blue instead. The cake was a huge hit. Here’s a picture:

Thanks so much for participating in this conversation about "a mom's life."

This is a place where moms can be themselves. Remember that each mother's path looks a little different. Please keep your comments respectful and kind. Reasonable minds will disagree in a nice way.

So let's talk about it, using "our big girl words."
