Make Your Cake & Mail It Too!

Anytime I find something with Sandra Denneler’s name attached to it, I immediately know it’s going to be great! Take this cake mail for example. Who wouldn’t love getting cake in their mailbox?

From the first time I saw this, I knew I wanted to try it, but it has taken me a while to convince myself to actually do it. I have three friends with birthdays on the same day, and I thought I might give this a try for them this year. (My supplies only made two slices of cake, so the third birthday girl is getting something different that I’ll be showcasing next week.)

Here’s the pin for Sandra’s original post.

In the steps below, I’ll show you my attempt to recreate Sandra’s clever creation. I’ve got to admit that I found myself craving cake during several steps of this, especially when it started to finally look like cake.

Step 1 Gather supplies.

Although this is a multi-phase project, it is still helpful to gather all supplies in the beginning. I used a grout sponge for this project, and it was the perfect size to make two cake slices. I also used the cheapest white caulk I could find; it was less than $2. The tan was around $4. I recommend using a thick cardstock for your postcard backing. The thicker the better.

Step 2 Cut the sponge into two wedges.

I ended up not having a serrated knife long enough to do the job, so I used a toothed knife. It was more difficult than I expected. I couldn’t use a sawing motion, so I had to cut in one direction, lift the knife, and re-insert to make the next cut. In some of the pictures, you can see all the ridges created by this method of cutting. For this project, the ridges aren’t a big deal because they ended up being covered by the postcard.

Step 3 Trim the cake edges to resemble real slices.

I used scissors to trim the cake slices. Scissors are much easier to use than a knife.

Step 4 Create the icing layer.

Cut out a middle section for the icing separating the cake layers. Super easy step. After you cut straight lines with the box knife, look how you can arch the cake slice and just cut out the piece with scissors. At this point, you’ll also want to trim off the narrow end of your cake. The end of mine wasn’t smooth and had a tear where I cut the icing layer.

Step 5 Paint the cake.

This step isn’t necessary if you want yellow cake. I wanted to send my friends chocolate cake, so I used a brown glossy paint. It required several layers of paint from various angles to really cover the yellow sponge.

Step 6 Trace and glue the postcard.

I chose colorful cardstock for my cake, but you could use any thick paper. Trace on the side of the paper that will be glued down so that your tracing lines won’t show and so that your paper is facing the right direction for your cake shape. I also chose to use hot glue instead of the spray adhesive Sandra uses because hot glue is what I have at home.

Step 7 Prep the caulk and caulking area.

Spread out some wax paper to protect surfaces. Also keep some dry and wet paper towels handy, as well as tools for spreading and swirling your caulk. I used wooden skewers and toothpicks. If you’re comfortable using a caulking gun, then I say have at it! I don’t feel like I get as much control using a gun as I do using cake decorating bags, so I put my caulk in Ziploc freezer bags for piping. I also didn’t realize until I was home from the hardware store that our caulking gun isn’t the same size as the tubes I bought, so I attempted to squeeze the caulk into the bags using the end of a hammer, and that made a huge mess when the hammer pushed through the bottom of the tube. I finally just spooned it into the bag.

Step 8 Pipe and swirl the icing layer.

Believe it or not, this is when the project got easier for me. I’m a big fan of keeping things simple, and the fact that this was similar to icing a real cake or playing with kids’ slime just made it easy. I just spread it and swirled it until it looked good.

Step 9 Pipe and swirl the top and sides.

The best part about this is that you can make it look like whatever you want – smooth it, swirl it, spike it. Have fun! It took less than half of a 10-ounce tube to do one slice.

Step 10 Dry them.

Let the slices air dry for a few days. Mine were okay to handle after two days, and I mailed them on day four. The thicker your caulk, the longer they will take to dry. Be sure to put them out of reach of kids and pets. Also try to put them in an area with less traffic to prevent dust from settling on them while they’re drying.

Step 11 Mail them.

Once dry, I was able to write my notes and add addresses and postage. Depending on weight, these cost between $2.50 and $3 to mail. Happy birthday, my friends!

Have your cake and mail it too...a fun mail tutorial from The Little Red Flag

My thoughts:

This project went mostly how I thought it would. It’s simple enough but must be done in steps because of paint and caulk drying times and because I have kids who would surely destroy the cake if I did this while they are awake. Sandra’s tutorial is easy to follow. I also found this tutorial that includes a video and a clever way to add sprinkles to your cake.

Overall, this is definitely a project I’d like to make again. It’s easy. It’s fun. And it’s sure to make any recipient smile.
