When it comes to baking, one of the most crucial elements that can make or break a cake or pastry is the frosting. A good frosting can elevate the overall taste and presentation of a dessert, while a bad one can be a major turnoff. One common issue that bakers face is achieving the right consistency for their frosting. It’s either too runny or too thick, and finding the perfect balance can be a challenge. This is where thickeners come into play, and one ingredient that has recently gained popularity as a thickening agent is potato starch. But can you use potato starch to thicken frosting? In this article, we’ll delve into the world of potato starch and its potential as a thickening agent for frosting.
What is Potato Starch?
Before we dive into its thickening properties, let’s first understand what potato starch is. Potato starch is a type of starch extracted from potatoes. It’s a fine, odorless, and flavorless powder that is often used in cooking and baking as a thickening agent. Potato starch is made by grinding potatoes and then separating the starch from the rest of the potato solids. The resulting powder is highly absorbent and has a high thickening power, making it an ideal thickening agent for a variety of applications.
The Science Behind Thickening Frosting
Thickening frosting is all about creating a stable emulsion that can hold its shape and provide a smooth, creamy texture. Frosting is typically made from a combination of sugar, fat (such as butter or cream), and liquid (such as milk or cream). When these ingredients are mixed together, they form an emulsion, which is a mixture of two or more liquids that don’t normally mix, such as oil and water. The key to a stable emulsion is to create a balance between the fatty and aqueous phases.
When we add a thickening agent to frosting, it helps to strengthen the emulsion by absorbing excess liquid and stabilizing the fatty and aqueous phases. This is where potato starch comes in. As a thickening agent, potato starch works by absorbing excess liquid and swelling, which increases the viscosity of the frosting. The starch granules also help to stabilize the emulsion by providing a physical barrier between the fatty and aqueous phases.
How to Use Potato Starch as a Thickening Agent for Frosting
Using potato starch as a thickening agent for frosting is relatively straightforward. Here are some general guidelines to follow:
- Start by mixing a small amount of potato starch with a liquid, such as cold water or milk, to form a slurry. This helps to prevent lumps from forming in the frosting.
- Add the potato starch slurry to the frosting mixture and mix until fully incorporated.
- Start with a small amount of potato starch, such as 1 tablespoon per cup of frosting, and adjust as needed.
- Be patient and mix slowly, as potato starch can take some time to absorb excess liquid and thicken the frosting.
Some important things to keep in mind when using potato starch as a thickening agent:
- Potato starch is a very effective thickening agent, so start with a small amount and adjust as needed. Too much potato starch can result in a stiff, unworkable frosting.
- Potato starch can affect the flavor and texture of the frosting, so it’s best to use it in combination with other thickening agents, such as butter or cream.
- Potato starch can also affect the color of the frosting, so it’s best to use it in conjunction with a stabilizer, such as glycerin or corn syrup, to prevent separation.

What is potato starch and how does it thicken frosting?
Potato starch is a starchy powder extracted from potatoes. It’s a popular thickening agent in many recipes, including frostings. When added to frosting, potato starch absorbs excess moisture and helps to strengthen the structure of the frosting, making it thicker and more stable. This is especially useful when making frostings with high-moisture ingredients like butter or cream.
The best part about using potato starch as a thickening agent is that it doesn’t affect the flavor or texture of the frosting. It’s a neutral-tasting ingredient that blends in seamlessly with the other ingredients. Additionally, potato starch is a great option for those with gluten intolerance or sensitivity, as it’s gluten-free.
How much potato starch do I need to add to my frosting?
The amount of potato starch needed to thicken frosting depends on the type of frosting and the desired consistency. As a general rule, start with a small amount (about 1-2 tablespoons) and add it gradually until you achieve the desired thickness. Be careful not to add too much, as it can make the frosting too stiff and difficult to spread.
It’s also important to note that the type of potato starch you use can affect the amount needed. Some potato starches are more concentrated than others, so be sure to check the packaging for instructions. Additionally, if you’re making a large batch of frosting, you may need to adjust the amount of potato starch accordingly.
Can I use potato flour instead of potato starch?
While potato flour and potato starch are both derived from potatoes, they are not interchangeable when it comes to thickening frosting. Potato flour is a coarser, more granular powder that contains more fiber and protein than potato starch. This can affect the texture and consistency of the frosting, making it grainy or dense.
If you don’t have potato starch on hand, it’s better to use cornstarch or another starchy thickening agent instead. However, if you do decide to use potato flour, be sure to sift it well to remove any lumps and use a small amount (about 1 tablespoon) to avoid affecting the texture of the frosting.
Will potato starch affect the flavor of my frosting?
One of the best things about using potato starch as a thickening agent is that it’s completely flavorless. Unlike other thickening agents like cornstarch or tapioca flour, potato starch won’t add any unwanted flavors or odors to your frosting. This makes it an ideal choice for delicate or sensitive flavor profiles.
Additionally, potato starch is odorless, which is a major advantage when working with frostings that require precise flavor profiles. Whether you’re making a classic buttercream or a fruity cream cheese frosting, potato starch is a safe choice that won’t disrupt the flavor.
Can I use potato starch to thicken whipped cream frosting?
While potato starch is an excellent thickening agent for many types of frosting, it’s not the best choice for whipped cream frostings. Whipped cream frostings rely on air incorporation to create their light and fluffy texture, and adding potato starch can disrupt this process.
Instead, try using a small amount of cornstarch or gelatin to thicken whipped cream frosting. These ingredients will help stabilize the whipped cream without affecting its texture or structure. If you do decide to use potato starch, be sure to use a very small amount (about 1 teaspoon) and whip the cream until it’s fully incorporated.
How do I store frosting thickened with potato starch?
Frosting thickened with potato starch can be stored in the same way as any other frosting. Simply transfer the frosting to an airtight container and store it in the refrigerator for up to a week. If you’re planning to store the frosting for longer, it’s best to freeze it and thaw it as needed.
When freezing frosting thickened with potato starch, be sure to press plastic wrap directly onto the surface of the frosting to prevent air from reaching it. This will help prevent the formation of ice crystals and keep the frosting smooth and creamy.
