You’ve made a cake and now you have some leftover frosting. What should you do with it? You can either freeze your buttercream or come up with a few different treat ideas to serve the kids. Let’s run through your options!

How Do You Reuse Refrigerated Frosting?
If you have leftover refrigerated frosting that you want to reuse, follow these steps:
- Bring it to Room Temperature: Take the frosting out of the refrigerator and let it come to room temperature. This will make it easier to work with.
- Stir or Mix: Frosting can sometimes separate or become stiff after refrigeration. Stir or mix it well to restore its smooth consistency. You can use a spoon or an electric mixer for this.
- Add Liquid if Needed: If the frosting is too stiff, you can add a small amount of liquid to soften it. Add a teaspoon of milk or water at a time and mix until you achieve the desired consistency. Be cautious not to add too much liquid at once, as it can make the frosting too runny.
- Adjust Flavor and Color: Taste the frosting to check if the flavor is still vibrant. You can add a bit more flavoring (like vanilla extract) if needed. If you want to adjust the color, you can incorporate food coloring a little at a time until you reach the desired shade.
- Check for Lumps: If the frosting has developed any lumps during refrigeration, try to smooth them out with a spatula or the back of a spoon. If the lumps are stubborn, you can strain the frosting through a fine mesh sieve to remove them.
- Use it for Decorating: Once the frosting is at the right consistency and flavor, you can use it to frost cakes, cupcakes, cookies, or any other baked goods. If you’re using it for decorating, ensure that it has the right stiffness for your desired decorations.
Remember that the quality of the reconstituted frosting may not be exactly the same as freshly made frosting, but these steps should help you salvage and reuse refrigerated frosting effectively.
What To Do With Leftover Frosting
Cake pops are a fun and easy way to use up leftover frosting. To make them, simply combine the frosting with some cake crumbs and roll them into balls. Then, dip the balls into melted chocolate and decorate as desired. You can also freeze the cake pops for an easy and tasty treat!
For a fun twist on traditional cupcakes, try making candy cups by spooning frosting into cupcake liners and freezing them. Once they are frozen, you can pop them out of the liners and enjoy as is, or dip them in melted chocolate for an extra special treat!

Can you save leftover frosting?
Yes, you can save leftover frosting in an airtight container in the refrigerator for up to 2 weeks or in the freezer for up to 3 months. Be sure to thaw the frosting in the refrigerator overnight before using it.
Here are some tips on how to store it properly:
- Refrigeration: If your frosting contains perishable ingredients such as butter or cream cheese, it’s advisable to store it in the refrigerator. Place the frosting in an airtight container to prevent it from absorbing odors or drying out. Make sure the container is well-sealed to prevent the frosting from picking up any unwanted flavors from the refrigerator.
- Freezing: Many types of frosting can be frozen for longer-term storage. Transfer the frosting to a freezer-safe container, leaving some room for expansion, as liquids may expand when frozen. Label the container with the type and date of the frosting. Before using frozen frosting, allow it to thaw in the refrigerator, and then bring it to room temperature before using.
- Airtight Containers: A key factor in preserving the quality of your frosting is to store it in airtight containers. This helps prevent exposure to air, which can lead to drying and changes in texture. You can also place a layer of plastic wrap directly on the surface of the frosting before sealing the container to minimize air contact.
- Separation and Re-Mixing: It’s normal for certain frostings to separate or develop a different texture after being stored. Before using the leftover frosting, give it a good stir or mix to restore its original consistency. If necessary, you can follow the tips mentioned in the previous response for bringing refrigerated frosting back to the right texture.
- Quality and Shelf Life: The shelf life of leftover frosting can vary depending on its ingredients. Be mindful of any perishable components, and use or freeze the frosting within a reasonable time frame to maintain its quality. While properly stored frosting can last for several days to a few weeks in the refrigerator, freezing can extend its shelf life for several months.
Always use your judgment and inspect the frosting before using it to ensure it’s still good. If you notice any off smells, unusual colors, or changes in texture, it might be best to discard the frosting and make a fresh batch when needed.

How long can you keep leftover frosting?
The shelf life of leftover frosting depends on its ingredients and how it’s stored. Here are some general guidelines:
- Refrigerated Frosting: If your frosting contains perishable ingredients such as butter, cream cheese, or milk, it’s advisable to store it in the refrigerator. Typically, refrigerated frosting can last for about 1 to 2 weeks. Before using it, check for any signs of spoilage, such as off odors or changes in color and texture.
- Frozen Frosting: If you choose to freeze your frosting, it can last much longer. Properly stored, frozen frosting can maintain its quality for 2 to 3 months or even longer. Use airtight containers and label them with the frosting type and the freezing date.
- Non-Perishable Frosting: Some frostings, especially those made with powdered sugar and shortening ingredients, can be more shelf-stable. In these cases, the frosting may last longer at room temperature. However, it’s still a good idea to store them in a cool, dry place and check for any signs of spoilage.
Always use your best judgment when assessing the quality of leftover frosting.
How do you refresh buttercream icing?
One way to refresh buttercream icing is to place it in the refrigerator overnight. This will help to firm up the frosting and make it easier to work with. You can also try mixing in a small amount of softened butter or cream cheese to give your icing a richer, creamier texture.
Additionally, you may want to consider adding some flavorings or spices, such as vanilla extract, cinnamon, or nutmeg, which can help rejuvenate the taste of your buttercream. Whatever method you choose, just be sure to mix the ingredients thoroughly before using your refreshed buttercream on your favorite baked treats!
Can I leave buttercream frosting out overnight?
It is generally recommended that you do not leave buttercream frosting out overnight, as it may start to go bad or develop mold. If you need to use your leftover frosting quickly, you may want to consider storing it in the refrigerator or freezer until you are ready to use it.
Can I melt frosting to make a glaze?
Yes, you can melt frosting to create a glaze. Here’s a simple guide on how to do it:
- Choose the Right Frosting: Some types of frosting are better suited for melting into a glaze than others. For example, buttercream and cream cheese frostings can be melted to create a smooth glaze. However, ganache, a mixture of chocolate and cream, can also be melted into a glossy glaze.
- Heat Gently: Use a microwave or a stovetop to heat the frosting gently. If using a microwave, heat the frosting in short intervals, stirring in between, until it reaches the desired consistency. Using a stovetop, use low heat and stir continuously to prevent burning or sticking to the pan.
- Add Liquid if Necessary: Depending on the type of frosting, you may need to add a small amount of liquid to achieve the desired glaze consistency. For example, you can add a teaspoon of milk or water at a time and stir until you get a smooth, pourable glaze.
- Strain if Needed: If the melted frosting has any lumps or bits that you want to remove, you can strain it through a fine mesh sieve before using it as a glaze.
- Apply the Glaze: Once the melted frosting is at the desired consistency, you can immediately use it as a glaze. Pour it over cakes, cupcakes, cookies, or any other baked goods, spreading it evenly with a spatula if needed.
Keep in mind that the final result will depend on the type of frosting you’re melting and the specific recipe. Additionally, some frosting may set quickly, so it’s a good idea to work efficiently once the frosting is melted.
Experiment with the process to achieve the texture and flavor you desire for your glaze. Enjoy your glazed treats!
