How far in advance can I make a smash cake?

You can bake the cake base up to 2 days ahead and store it wrapped at room temperature. Frosted smash cakes stay fresh for 24 hours when stored in the refrigerator. I recommend assembling your final decorations the morning of your party for the freshest appearance and best photo results.

What size should a smash cake be for a one-year-old?

A 6-inch round cake is perfect for smash cake adventures. This size provides enough cake for thorough exploration without overwhelming your little one. The proportions photograph beautifully and give babies plenty of surface area to dig into while remaining manageable for their tiny hands

Can I make these smash cake recipes without eggs for babies with allergies?

Absolutely! Replace each egg with 1 tablespoon of ground flaxseed mixed with 3 tablespoons of water, let it sit for 5 minutes until gel-like. You can also use commercial egg replacers following package directions. The texture will be slightly different but still delicious and perfect for smashing adventures

Instructions

1. Prepare the Base Cake

Preheat oven to 350°F (175°C) and grease a 6-inch round cake pan.
In a large bowl, cream butter and sugar until light and fluffy. Add eggs one at a time, then vanilla extract.
In a separate bowl, whisk flour, baking powder, and salt. Alternate adding dry ingredients and milk to butter mixture, starting and ending with dry. Mix until just combined.
Pour batter into pan and bake 25–30 minutes. Cool completely.

2. Frosting & Decorating Options

Classic Vanilla Rainbow:

Divide buttercream into 3 bowls, tint each with different colors. Pipe or spread in swirls and top with rainbow sprinkles.

Chocolate Mud:

Cover cake with chocolate buttercream, create textured peaks. Press in crushed chocolate cookies and add gummy worms for a playful effect.

Strawberry Cloud:

Mix strawberry puree into cream cheese frosting for pink color. Spread or pipe generously and decorate with fresh strawberry slices.

3. Timing

Cake Base: Bake 2 days before party.
Frosting: Prepare 1 day before, store covered in fridge.
Assembly: Assemble 2–3 hours before celebration for best freshness and photos.

Notes

Room temperature ingredients blend better; leave eggs and dairy out 1–2 hours before baking.

Cool cake completely or freeze 15 min before frosting for stability.

Apply a thin crumb coat and chill 30 min for smooth final layer.

Use offset spatulas for smooth application; piping bags enhance decorative designs.

Store leftovers in fridge for up to 4 days; unfrosted layers freeze up to 3 months.

For baby-friendly version, replace sugar with unsweetened applesauce, use whole wheat pastry flour, or dairy-free ingredients.

Gluten-free option: substitute gluten-free chocolate cookies.

Overmixing creates dense cake – mix just until combined.

Pair with fresh fruit cups; set up plastic tablecloths for a mess-friendly smash session.
