Baby Shower "Gifts" Cake

This cake I made for my sister in law's very first baby shower.  As you can see she is having a little girl and everyone is just ecstatic!

Note: I know the pictures are not so great, I forgot my camera and these are taken with my phone.  Also, I'm sorry I don't have step by step pictures, I did most of this cake in one night and was super rushed to get it done.

The bottom tier is a 12x12 3 layer cake: Almond/ Vanilla Cake with Cream Cheese Filling (mommy to be's favorite).  The "lid" of the gift box is a single layer of cake covered in fondant.
The middle tier is a 9 inch round 3 layer cake: Chocolate Cake with Chocolate Fudge Filling.  The "lid" of the gift box is rice krispie treats covered in fondant.
And the top tier is the smallest pan of the Wilton Pillow set.  It was pound cake but I did not serve it.

All the fondant is homemade marshmallow fondant and the decorations are 50/50 fondant and gum paste (Satin Ice). 

To get the boxes to look open here is what I did...

I started with a piece of plywood (1/2") and screwed a flange to the middle of it.  Then I screwed a piece of PVC to that to give the cake stability.  Then as I would finish a tier I would cut a hole in the center and "thread" the PVC through the middle of the tier.

Then I doweled the cake....  for instance on the 12x12 I placed three dowels on one side (flush with the cake) and then three on the opposite side about one inch above the cake.

Then when I placed the "lid" on the "box" it was propped open and I "glued" the area that touched the box with royal icing.  On top of the open lid I placed a wedge of cake covered in royal icing.  Then when the middle tier went on it was level.  The process was then repeated with the middle tier.

The baby shoes are made from a 50/50 gum paste fondant mixture and dried for two weeks.  I also painted them with luster dust.

The baby blocks on the side of the cake are rice krispie treats covered in fondant.

I hope I didn't forget anything... sorry I'm rushed for time posting this.  If you have questions please feel free to ask.  :)
