There’s a moment after every birthday party when the candles are blown out, the guests have gone home, and you’re left standing in the kitchen staring at… a lot of leftover cake.
This year, after celebrating our daughter’s 13th birthday (how did that happen so fast?), we found ourselves with several uneaten slices of perfectly good cake. Normally we’d send some home with friends or sneak forkfuls straight from the fridge for the next few days. But this time, we decided to try something a little different.
We’re freeze drying it.
Because if you live a homestead life, eventually you look at everything and wonder, “Can we preserve that?”

Why Freeze Dry Cake?
Freeze drying isn’t just for fruits, veggies, or full meals. One of the things we love most about having a freeze dryer is the ability to experiment and reduce waste in ways we never could before. Birthday cake felt like the perfect test:
- We didn’t want it to go to waste.
- It’s already a special memory—why not make it last?
- And honestly… we were curious what freeze-dried frosting would turn into.
(For science, obviously.)
What We’re Hoping For
From what we’ve learned, freeze-dried cake should come out light, airy, and almost melt-in-your-mouth—kind of like a crispy sponge that snaps when you bite it. The frosting should dry into a sweet, creamy crumble.
Our hope is that this turns into a fun treat we can:
- Toss into lunches as a surprise dessert
- Bring along on camping trips
- Save as a little time capsule from her 13th birthday year
- Or just snack on when we want something sweet without baking again
Because let’s be honest—if we can preserve memories and dessert at the same time, that’s a homestead win.
The Process (So Far)
We sliced the leftover cake into smaller portions so it would freeze-dry evenly, making sure there was space between pieces for airflow. Into the trays it went—frosting, sprinkles, layers, crumbs, and all.
Now the machine is doing its thing, pulling out moisture slowly and turning this once-fluffy birthday centerpiece into something shelf-stable.
And yes, the kitchen still smells faintly like vanilla cake, which is not a bad problem to have.

Why We Love Experiments Like This
Homesteading, for us, has always been about learning as we go. Not everything has to be traditional food preservation. Sometimes it’s about asking:
“What do we have right now, and how can we make it last?”
Sometimes that’s tomatoes.
Sometimes that’s broth.
And sometimes… it’s birthday cake.
It’s these little experiments that make the lifestyle fun and keep the kids involved. Our daughter is especially invested in seeing how her cake turns out—which makes this feel even more meaningful.
We’ll Share The Results Soon
We’ll report back once the cycle is finished and we’ve had a chance to taste-test (the best part). We’re just as curious as you might be:
Will it be crunchy?
Will the frosting work?
Will it actually taste like cake?
Stay tuned—we’ll do an update post with the final results, photos, and whether freeze-dried birthday cake is something we’ll be doing again… or chalking up to experience.
Either way, it’s one more memory preserved.

The Freeze Dryer We Use and Recommend
If you’ve been curious about getting into freeze-drying yourself, we use a Harvest Right freeze dryer on our homestead and have been very happy with it. It’s allowed us to preserve everything from garden harvests to full meals—and now even birthday cake—while reducing waste and building a pantry that truly lasts. It’s definitely an investment, but for our family, the ability to store food long-term, experiment with fun projects like this, and make the most of what we raise and grow has made it well worth it.
