I came up with a quick template (well, it should have been quick, but I'm a dunce when it comes to Illustrator, so it took a while!), printed a bunch out on my kraft cardstock, cut, and taped. I made a really good, vanilla buttermilk cake with vanilla frosting and rainbow sprinkles, boxed up the slices, and delivered them! It was so much fun! Happy Birthday to me!
Click HERE to download the template. The assembled boxes will fit cake slices from a 1- or 2-layer 8" round cake that has been cut into at least 12 pieces. And click HERE if you'd like the recipe for the Vanilla Buttermilk Cake!
Print out as many boxes as you'll need on cardstock.
Cut on the solid lines.
Fold on the dotted lines. A bone folder would work nicely here, but I can never find mine when I need it, so I just used my fingernails.
Use double-sided tape to attach the overlapping flaps to the sides of the box.
Do this one first, then wait until you've slid the piece of cake into position to do the other two. Just trust me on that one. ;)
