Last Updated on September 14, 2024 by Shari Mason

**Grabbing frosting from the store** is a quick way to finish decorating cakes and cupcakes, yet **getting that ideal texture** can be tough.

If your store-bought frosting is too thin or runny, it can be not easy to work with and may not hold its shape. 

Fortunately, there are several simple ways on how to thicken store-bought frosting and achieve the perfect consistency for your decorating needs. 

5 Ways To Thicken Store-Bought Frosting

1. Add Powdered Sugar

Adding powdered sugar is a quick and easy way to thicken the store-bought frosting. Add a tablespoon of powdered sugar to the frosting, mixing well after each addition. 

Continue adding powdered sugar until the frosting reaches the desired consistency. Be sure to taste the frosting to avoid adding too much sugar. 

Remember that adding powdered sugar [1] can also change the flavor and sweetness of the frosting, so use this method with caution. 

Additionally, be careful not to add too much sugar, as this can cause the frosting to become too thick and difficult to spread.

2. Chill The Frosting

Chilling store-bought frosting is another effective way to thicken it up. Place the frosting in the refrigerator for 15-20 minutes, then stir it well. 

This allows the frosting to cool and solidify, which can help it to thicken. If the frosting is too thin, repeat the process until it reaches the desired consistency. 

However, remember that chilling the frosting may affect its flavor and texture, so use this method cautiously. 

Additionally, if the frosting becomes too thick after chilling, let it come to room temperature and stir it well to loosen it up again. 

This simple technique lets you quickly thicken your store-bought frosting and achieve a smooth and spreadable texture.

3. Use Cornstarch

Using cornstarch is another effective way to thicken the store-bought frosting. Mix a small amount of cornstarch [2] with water to create a slurry. Then, add the slurry to the frosting and mix well. 

Heat the frosting in the microwave or stove for a few seconds to activate the cornstarch, frequently stirring to prevent clumping. Be careful not to add too much cornstarch, as this can cause the frosting to become too thick and difficult to spread. 

This technique lets you quickly thicken your store-bought frosting and achieve a smooth and spreadable texture.

However, keep in mind that adding cornstarch can also affect the flavor and color of the frosting, so use this method cautiously.

4. Whip The Frosting

Whipping the frosting can help to thicken it by incorporating air and making it fluffier. To whip store-bought frosting, use a hand or stand mixer on low speed, then gradually increase the speed to medium-high. 

Whip the frosting until it reaches the desired consistency, being careful not to overwhip it, which can cause it to become too thick and difficult to spread. 

This method gives your frosting a light and airy texture, perfect for decorating cakes and cupcakes. However, remember that this method may not work well for frostings that are already too thin or runny.

5. Add Cream Cheese

Adding cream cheese to store-bought frosting can help to thicken it and add a tangy flavor. To add cream cheese to your frosting, start by using softened cream cheese, as this will make it easier to mix into the frosting. 

Mix the cream cheese into the frosting using a hand or stand mixer to ensure it is fully incorporated. Be sure to mix the frosting well to avoid any lumps or clumps of cream cheese.

Remember that adding cream cheese will change the flavor and texture of the frosting, so use this method with caution.

This technique works particularly well for frostings that are too thin or runny, as it can help to add structure and thickness to the frosting.
