Making cake boxes with cardboard paper

Updated March 23, 2017

Decorative cakes, cupcakes and cookies often require a small cardboard box to be transferred. Homemade cardboard boxes are simple to make and can be decorated to suit special occasions. You can make a box to suit the smallest of cakes or a larger cake with a thick layer of icing. Whatever the preference, cake boxes can be designed and constructed to suit all needs.

For a box measuring 5 inches by 5 inches, cut out two pieces of cardboard, the first 12 inches by 12 inches, the 12 1/2 inches by 12 1/2 inches. For a larger box, adjust the measurements.

On the smaller square, draw two lines, from one corner to the corner opposite. Essentially, the square should have an X on it.

Fold one of the corners into the centre of the X drawn in the previous step. Fold this fold toward the X again, so the first fold line is lined up to the middle of the X. Unfold both folds. Repeat this step for each corner.

Assemble the box by folding two opposite corners to meet in the centre of the X. Fold the folds again to create two sides of the box. Apply glue underneath the triangles created in the middle to hold these folds in place.

Pick a corner that has not been folded. Bend the corners of the box, not the square, inward, creating two triangles. The corner of the square has now become narrow. Bend it, so it stands straight up in the air. Apply glue to the top of the corner as it stands high. Fold this corner down over the two triangles to create a third side to the box. Apply pressure to the glue to secure the fold in the centre of the box.

Repeat this fold with the remaining corner of the square to complete the box.

Repeat the above steps with the larger square to create the other cardboard box. The larger box will serve as the lid.

Decorate the cake box to suit the occasions for which it will be used. Add decorative paper using glue, paint the box with acrylic paints or embellish the box with stickers for a quick alternative that adds sparkle.
