Cardboard Cake Boards

Basic Properties

Cardboard cake boards are made from pressed paper and come in thicknesses of 1/16 inch (supports 2–3 pounds) and 1/8 inch (supports 5–6 pounds). They are available in round (6–18 inches), square, and rectangular shapes.

  • Single-ply boards (1/16 inch): Suitable for cakes up to 2–3 pounds.
  • Double-ply boards (1/8 inch): Can handle cakes weighing 5–6 pounds.

Gloria's Cake & Candy Supplies provides food-grade cardboard boards coated with a non-toxic, grease-resistant layer. This coating helps protect against moisture and increases durability.

These features influence how these boards perform in different situations.

Pros and Cons

Aspect Advantages Disadvantages
Cost Affordable option Limited to single-use
Weight Lightweight and easy to carry May bend under heavier cakes
Storage Compact and space-saving Can warp if stored improperly
Versatility Available in various sizes/shapes Not ideal for very moist cakes
Disposal Recyclable and eco-friendly Needs frequent replacement

Cardboard cake boards are best suited for:

  • Single-tier cakes weighing less than 5 pounds
  • Sheet cakes up to 12 × 18 inches
  • Short-term displays (1–2 days)
  • Indoor events with controlled temperature and humidity

For buttercream cakes, use a moisture barrier like food-safe aluminum foil or decorative wraps to keep the board intact. If you're handling heavier cakes, double-stack the boards to add extra support. Always place the board on a flat surface to avoid mishaps.

Foam Cake Boards

Key Features

Foam cake boards come with a core that resists moisture and a finish that’s safe for food contact. Below, you'll find a breakdown of their advantages and drawbacks.

Pros and Cons

Feature Advantages Drawbacks
Durability Resists moisture, reducing warping Can be damaged if not handled carefully
Weight Support Stable enough for heavier cakes Often more expensive than alternatives
Reusability Easy to clean and reuse Needs extra storage space
Temperature Works well in refrigerated settings Unsuitable for direct heat exposure
Surface Smooth finish for a polished look Limited options for surface designs

Best Uses

Thanks to their lightweight yet sturdy nature, foam boards are ideal for cakes that need both style and function. They’re especially great for layered cakes. Just make sure the board is slightly larger than the cake to keep everything stable.

Masonite (MDF) Cake Boards

Masonite boards are a solid choice when you need extra support for heavier cakes, offering a middle ground between standard boards and professional-grade options.

Key Properties

These Medium Density Fiberboard (MDF) cake boards are known for their strength and stability. Made from engineered wood composite, they have a smooth, food-safe coating that keeps moisture out. Their thickness typically ranges from 1/4 inch to 1/2 inch, making them a reliable option for heavier cake designs.

Property Specification
Material Engineered wood composite
Thickness 1/4" - 1/2"
Weight Capacity Up to 50 lbs
Surface Finish Food-safe sealed coating
Core High-density compressed fibers

Pros and Cons

Masonite boards have distinct strengths and trade-offs that influence their practicality for cake presentations:

Feature Benefits Limitations
Strength Handles multi-tiered cakes with ease Heavier than other board types
Durability Retains shape under heavy loads Not washable
Surface Quality Smooth and flat for perfect presentation Limited color options
Cost Long-lasting and reliable Higher upfront cost
Moisture Resistance Sealed to resist humidity Avoid direct water exposure

Masonite boards shine in situations where extra strength and stability are key. They work particularly well for:

  • Wedding Cakes: Perfect for multi-tier designs weighing 25–50 lbs.
  • Display Cakes: Great for bakery window displays that need to last.
  • Sculpted Cakes: Provides a steady base for intricate 3D designs.

To get the best results, choose a board that’s at least 2 inches larger than your cake’s base. For tiered cakes, use proper supports to evenly distribute the weight.

Plastic Cake Boards

Plastic cake boards are a practical choice for displaying and serving cakes. They combine sturdy construction with features that make them a good option for certain cake styles and events.

Key Properties

These boards are made from food-safe plastic, offering strong moisture resistance and the ability to be reused. They typically range in thickness from 1/8 inch to 1/4 inch and have a smooth, non-porous surface that keeps liquids from soaking in.

Property Specification
Material Food-grade plastic
Thickness 1/8" - 1/4"
Weight Capacity Up to 15 lbs
Surface Finish Smooth, non-porous
Core Solid plastic design

Pros and Cons

Here’s a closer look at what plastic cake boards bring to the table, as well as their potential downsides:

Feature Benefits Limitations
Durability Reusable and dishwasher-safe Can scratch or warp with heat
Weight Lightweight and easy to carry May not be stable for very heavy cakes
Moisture Resistance Completely waterproof Can become slippery when wet
Temperature Tolerance Safe for -40°F to 140°F May deform in extreme heat
Cost Efficiency Saves money over time with reuse Higher upfront cost compared to disposable options

These boards shine in certain situations, but it’s important to consider their limitations when planning your cake project.

Plastic cake boards are especially useful in scenarios where their unique features stand out:

  • Single-Layer Cakes: Best for cakes weighing 15 lbs or less.
  • Refrigerated Displays: Great for cakes stored in cold environments.
  • Outdoor Events: Moisture resistance makes them ideal for humid conditions.
  • Frequent Transport: Their lightweight design is perfect for easy delivery.

For optimal results, select a board that’s 2-3 inches wider than your cake. When working with tiered cakes, use additional supports between layers to evenly distribute the weight. Always store these boards flat in a cool, dry spot, and keep them away from direct sunlight or heat sources above 140°F to avoid warping.

How to Pick the Right Board

Choosing the right board is crucial for ensuring your cake's safety and presentation. Building on earlier material insights, your board selection should align with your cake's specific needs.

Key Factors to Consider

When choosing a cake board, focus on these important factors:

  • Weight Capacity: The board must support your cake's weight without bending or breaking.
  • Moisture Resistance: Think about the type of frosting or filling and whether it might affect the board.
  • Usage Duration: Decide if you need a single-use or reusable board.
  • Environment: Consider conditions like heat, humidity, or cold storage.
  • Transportation: Account for how far and how often the cake will be moved.
Factor Considerations Best Board Choice
Heavy Cakes (15+ lbs) Strong structure, weight distribution Masonite/MDF
Humid Environments Resistance to moisture and warping Plastic or Foam
Short-term Display Budget-friendly, disposable Cardboard
Frequent Transport Durable and lightweight Plastic or Foam
Cold Storage Handles temperature and moisture Plastic

Matching Board Types to Cake Sizes

The size and weight of your cake determine the best board type and size. Proper support is essential for stability and safe transport. Use the table below as a guide:

Cake Size Weight Range Recommended Board Type Board Size Recommendation
6" Round 2-4 lbs Cardboard or Foam 8"
8" Round 4-6 lbs Foam or Plastic 10"
10" Round 6-10 lbs Plastic or MDF 12"
12"+ Round 10+ lbs MDF 14"+
Sheet Cake 15-25 lbs MDF or Double-layer 2" larger than cake
Tiered (3+) 20+ lbs MDF with supports 4" larger than base

For cakes that are tiered or frequently moved, prioritize boards that are durable and distribute weight evenly. Heavy or tiered cakes often benefit from using a sturdy base board combined with thinner separator boards between layers.

Thickness Matters: For smaller cakes (under 8 inches), a 1/8-inch thick board is usually enough. Larger cakes (10 inches or more) should have boards at least 1/4-inch thick to prevent sagging and ensure safe handling.

Summary

Picking the right cake board is crucial for safe display and transport. Here's a quick rundown of the main materials and their ideal uses:

  • Cardboard boards: Great for lightweight, single-use cakes.
  • Foam boards: Resist moisture and work well for medium-weight cakes.
  • Masonite/MDF boards: Perfect for heavy, tiered cakes.
  • Plastic boards: Combine reusability with moisture resistance.

Choose a board material that matches your cake's weight and display needs. For thickness, go with 1/8-inch boards for cakes under 8 inches and at least 1/4-inch for larger ones. For tiered cakes, use a strong base and thinner separators to ensure stability.

Gloria's Cake & Candy Supplies offers a wide selection of cake boards for any project. Their team can guide you in picking the right board, whether it's for a simple 6-inch round or a complex tiered design.

When making your choice, consider:

  • The cake's size and weight
  • Display conditions
  • Transportation needs
  • How long the board will be used
  • Your budget
