When you want the big, beautiful cake– but you don’t want all the leftovers. This Half Birthday Cake is a fun, small-batch alternative to a traditional layered birthday cake!

I knew I wanted a BIG, beautiful, layered chocolate cake with chocolate frosting and vanilla buttercream filling for my birthday. But I also knew I wasn’t going to have many people eating it.

Between diets, food sensitivities, and the fact that my parents showed up with an entire pie (so freaking good).

I could have ended up with a LOT of leftover birthday cake. So I preemptively solved the problem by making only half of a cake!

It’s so much easier than you would think! I even made you a video to show you how I did it.

A FEW THINGS TO NOTE ABOUT THIS RECIPE:

  • CHILL, CHILL, CHILL! The key to any layered cake is to keep it chilled every step of the way. But when working with HALF of a cake (with half the stability), it was especially crucial to have a completely chilled cake from start to finish. In the video, you can see my cake is leaning a little bit. That’s because I didn’t have the time to let it chill completely! If I had taken the time to chill it after each step, I’d EASILY have a perfectly straight standing cake.
  • I’d also highly recommend keeping it chilled up until it’s time to serve!
  • I used my favorite doctored up cake mix recipe for the cake. And it makes A LOT of cake. As you can see in the video, it made two VERY thick 10-inch rounds. Which was a little too much to stack in 4 layers, so I only used 3. If you use my recipe, you can just save half of one cake by wrapping it in plastic wrap and freezing it. But FYI: if you were to simply bake a cake using a cake mix according to the directions on the box (instead of my fancied-up version), you should be able to stack all four layers with no problem.
