I made this printable a while ago when I was in Activity Days (scouts type group for 8-11 yr old girls). I needed a cheap and easy way to say that we care, and, of course, Happy Birthday. This fit the bill perfectly. I just filled each cake with candy/toys and we're set! Quick and inexpensive - which is perfect!
Cut out along the solid lines. Use this chance to sign your name or write a message on the bottom of the cake.
Fold like so.
I didn't put dotted lines to help with this part because I didn't want it to be ugly. :) Notice that the image goes over the fold lines, that's part of the look. When folding follow the corners to make rectangles and triangles as common sense dictates.
I found a combination of glue stick and tape are the best way to keep it together.
Attach the corners together to form the slice.
Next, wrap the candle around a pen, and take and glue closed.
I clipped the bottom to make it look like a little rocket. That will make it easy to attach to the cake slice.
Use a hole punch to make a hole for the candle wherever you want.
Your candle is likely bigger than your hole punch, so clip the hole to look like a little sun. I pushed in the hole with my pen and slid in the candle.
You should be left with the candle flaps flared out inside the box. Tape that sucker down.
Next fill the box with your desired treats and slide the tabs together. Tabs inside to leave a clean back.
Here's a view of your finished box and...
... here's the top! All done! Not quite as awesome and delicious as a real cake, but pretty close, and WAY more convenient. Plus it's sugar, fat, dairy, gluten free and 100% fiber! Ha!
