Icing is thinner and smoother for glazing or decorating, while frosting is thicker, fluffier, and used to coat and fill cakes and cupcakes.
If you’ve ever watched a cake decorating video or followed a baking recipe, you’ve probably wondered about the difference between icing and frosting.
Many people use the terms interchangeably, but professional bakers often treat them as two different toppings with distinct textures, ingredients, and purposes.
The difference between icing and frosting mainly comes down to consistency and application. Frosting is usually thick, fluffy, and spreadable, while icing is thinner and often poured or drizzled.
Understanding the difference between icing and frosting can help you choose the perfect finish for cakes, cookies, cupcakes, donuts, and pastries.
In this guide, you’ll learn what icing and frosting are, how they differ, when to use each, common mistakes, real-world examples, and expert baking insights that make choosing the right topping easy.
Difference Between Icing and Frosting
Frosting is thick, creamy, and spreadable, while icing is thinner, smoother, and often used as a glaze or drizzle. Frosting adds volume and decoration, whereas icing creates a shiny finish.
Example: A birthday cake is commonly covered with buttercream frosting, while cinnamon rolls are often topped with a sweet icing glaze.
Definition of Icing and Frosting
- Icing: A sweet topping made from powdered sugar and liquid that creates a smooth, thin coating or glaze.
- Frosting: A thick, creamy topping typically made with butter, sugar, cream, or similar ingredients for spreading and decorating baked goods.
Example: Royal icing is used on decorated cookies, while buttercream frosting is commonly used on cakes.

Key Differences Explained Between Icing and Frosting
1. Texture
The biggest difference is texture.
Icing flows easily and creates a smooth coating. Frosting holds its shape and can be piped into decorative designs.
Example: Cookie decorations often use icing, while cupcake swirls use frosting.
2. Thickness
Frosting is much thicker.
This makes it ideal for covering entire cakes and creating decorative borders.
Icing is thinner and spreads naturally.
3. Ingredients
Most icing recipes use powdered sugar combined with milk, water, or lemon juice.
Frosting often includes butter, cream cheese, whipped cream, or shortening.
4. Decorative Function
Icing excels at intricate details.
Frosting excels at creating volume and texture.
Professional cake decorators often use both in the same project.
5. Hardening Ability
Many icings dry and harden after application.
Most frostings remain soft and creamy.
This difference affects storage and transportation.
6. Visual Appearance
Icing typically produces a shiny surface.
Frosting creates a rich, textured finish.
7. Flavor Experience
Frosting usually offers a richer taste because of butter and dairy ingredients.
Icing tends to provide a sweeter, lighter sugar flavor.
What Is Icing and How Does It Work?
Icing is a sugar-based coating that forms a smooth layer over baked goods.
Common types include:
- Glaze icing
- Royal icing
- Fondant icing
- Sugar icing
- Lemon icing
The liquid-to-sugar ratio determines how thick or thin the icing becomes.
In practical baking, icing is often chosen when a clean, polished appearance is desired.
What Is Frosting and How Does It Work?
Frosting is a creamy mixture designed to add flavor, texture, and decoration.
Popular frosting varieties include:
- Buttercream frosting
- Cream cheese frosting
- Whipped frosting
- Chocolate frosting
- Swiss meringue buttercream
Because frosting contains fats such as butter or cream, it creates a richer mouthfeel than icing.
Difference Between Icing and Frosting for Cakes
When decorating cakes, frosting is usually the preferred choice.
Why Bakers Choose Frosting
- Covers cake layers easily
- Creates decorative borders
- Supports piping designs
- Adds moisture
- Provides richer flavor
Icing may still be used on cakes, particularly for glazes and specialty finishes.
Difference Between Icing and Frosting for Cookies
Cookies often use icing because it hardens after drying.
Advantages of Icing on Cookies
- Smooth finish
- Detailed artwork
- Easier stacking
- Longer-lasting decorations
This is why holiday cookies and decorated sugar cookies frequently use royal icing.
Why Does the Difference Between Icing and Frosting Matter?
Choosing the wrong topping can affect:
- Appearance
- Texture
- Flavor
- Storage
- Decoration quality
For example, using icing where frosting is needed may result in insufficient coverage. Using frosting where icing is needed may prevent intricate decorative work.
Professional bakers select the topping based on the desired final result.
How Professional Bakers Use Icing and Frosting
Commercial bakeries use both products strategically.
Frosting Applications
- Birthday cakes
- Wedding cakes
- Cupcakes
- Layer cakes
Icing Applications
- Donuts
- Sugar cookies
- Cinnamon rolls
- Pastries
In real-world bakery operations, choosing the correct topping improves both appearance and customer satisfaction.
Can Icing and Frosting Be Substituted?
Sometimes, but not always.
A glaze icing can replace frosting for a lighter finish.
However, frosting cannot always replace icing when detailed decorations or hardening properties are required.
Understanding the purpose of each helps achieve better baking results.
