How to Build a Diaper Cake for a Baby Shower Step by Step

Quick Answer

Building a diaper cake is simpler than it looks. You need about 35 size 1 diapers, a few rubber bands, and a cardboard base. Stack the rolled diapers in three tiers, secure each layer, and decorate with baby essentials like shampoo and lotion.

What You’ll Need Before You Start

Gather 35–50 size 1 diapers (the most common newborn size), a round cardboard or cake board for the base, rubber bands or ribbon, and a hot glue gun. For a ready-made option, Honest Diaper Cakes like the Turtle Time style come pre-packed with 35 Clean Conscious Diapers plus a 2.0 fl. oz Shampoo + Body Wash, saving you assembly time.

Choose a theme or color scheme to match the baby shower. Neutral greens and blues work for any gender, while character prints like those in the Above It All cake add a playful touch. Avoid using diapers smaller than size 1—they won’t stack as neatly and may not fit the baby long.

Rolling the Diapers Correctly

Take each diaper and roll it tightly from the waistband toward the back, then secure it with a small rubber band or a piece of ribbon. The roll should be firm but not so tight that the diaper loses its shape. A common mistake is rolling too loosely, which makes the cake wobble.

If you’re using a pre-made cake like the Turtle Time, the diapers are already rolled and layered, so you can skip this step and focus on decorating. For a DIY approach, roll all diapers before stacking to keep the process smooth.

Stacking the Layers

Start with the bottom tier: arrange rolled diapers in a circle around a central support (like a rolled-up towel or a cardboard tube). Use a rubber band to hold them together. Repeat for the middle and top tiers, making each tier slightly smaller. A three-tier cake typically uses 20 diapers for the bottom, 12 for the middle, and 8 for the top.

Checkpoint: Ensure each tier is level before adding the next. If the cake leans, adjust the rubber bands or add a small piece of cardboard under one side. A level base prevents the cake from toppling during transport.

Decorating and Adding Practical Gifts

Once the tiers are stacked, secure them with a long ribbon or decorative string tied around the entire cake. Then tuck in baby essentials like a small bottle of lotion, a pacifier, or a teether between the layers. Honest’s Disney and Pixar's Toy Story Face + Body Lotion (2.0 fl. oz) fits perfectly in the gaps and adds a practical, moisturizing gift for the new parents.

Avoid overloading the cake with heavy items that could crush the diapers. Stick to lightweight, flat items for the top tier. A common mistake is using too much glue or tape, which makes the cake look messy—use ribbon or string for a clean finish.
