10 Tips To Keep Your Cake Cool in Hot Weather

When the summer heat is on, the last thing you want is for your beautifully decorated cake to turn into a melting disaster. Keeping your cake cool in hot weather requires some planning and strategic measures to ensure that your creation remains intact and delicious. In this comprehensive guide, we will share expert tips and tricks to help you keep your cake cool and prevent it from melting in the scorching heat.

1. Choose the Right Frosting

The type of frosting you use plays a crucial role in keeping your cake cool and stable in hot weather. Some frostings have better heat resistance and hold their shape better than others. Buttercream and fondant are known for their ability to withstand heat. They provide a protective barrier around the cake, preventing it from melting or losing its shape. On the other hand, whipped cream or cream cheese frostings are more prone to melting in hot temperatures.

To weatherproof your frosting, there are a few things you can do:

  • Increase the stability of your frosting by adding more powdered sugar or reducing the amount of liquid ingredients.
  • Use a frosting with more heat-resistant ingredients, such as buttercream or fondant.
  • Avoid using fillings that are runny or gooey, as they can compromise the stability of your cake. Opt for fillings that are more stable, such as fruit preserves or ganache.

2. Proper Storage and Transportation

Proper storage and transportation are essential to prevent your cake from melting on the way to your destination. Here are some tips to ensure your cake remains cool and intact:

  • Before transporting your cake, make sure it is thoroughly chilled in the refrigerator. This will help the frosting and filling to set, providing better stability.
  • If possible, transport your cake in an insulated cooler or a cake carrier with built-in cooling features. These containers help to maintain a cool temperature and protect your cake from the heat outside.
  • If you don't have access to a cooler or a cake carrier, you can create a makeshift portable refrigerator by using a large box lined with freezer packs or ice packs. Place your cake box inside the second box, ensuring it is surrounded by the cooling elements.
  • Use dry ice to keep your cake cool while transporting it. Wrap the dry ice in a towel or newspaper and place it in a separate container beside the cake box. Handle dry ice carefully and follow safety guidelines. When traveling by car, turn on the AC and let it circulate before placing the cake inside to create a cooler environment.

3. Strategic Timing

Timing is everything when it comes to keeping your cake cool in hot weather. By planning your cake preparation and transportation strategically, you can minimize the time your cake spends in the heat. Here are some tips to help you manage the timing effectively:

  • Finish decorating your cake as close to the event or serving time as possible. This will reduce the amount of time your cake is exposed to the heat.
  • If you are transporting the cake to an outdoor venue, try to arrive as close to the serving time as possible. This will minimize the time your cake spends in the heat outside.
  • If you need to refrigerate your cake before serving, remove it from the refrigerator at the last moment before transporting it to the venue. This will help maintain its cool temperature for as long as possible.

4. Shield Your Cake from the Sun

Direct sunlight can quickly turn your beautifully decorated cake into a melted mess. It's crucial to protect your cake from the sun's rays to keep it cool and intact. Here are some strategies to shield your cake from the sun:

  • When setting up your cake at an outdoor venue, look for a shaded area or create shade using umbrellas or canopies. This will help prevent direct sunlight from hitting your cake.
  • Avoid placing your cake near windows or areas with direct sunlight, both during transportation and at the venue.
  • If you're traveling with your cake in a car, use a car window shade for un-tinted windows to block out the sun's heat.

5. Strategic Support and Stacking

Proper support and stacking techniques are essential to keep your cake stable in warm weather. Here are some tips to ensure your cake remains structurally sound:

  • Use a sturdy base for your cake, such as a wooden board or a cake drum. Corrugated cardboard cake rounds are not sufficient for stacking tall or heavy cakes.
  • If you're stacking multiple tiers, make sure to use dowels, straws, or a premade cake stacking frame to provide support between the layers. Dowels should be cut slightly longer than the tier's height to prevent the upper tiers from putting pressure on the lower ones.
  • Consider creating a "dam" around each layer of your cake by using a ring of frosting, such as buttercream or ganache. This helps to hold back the filling and provides additional stability, especially in hot weather.
  • Choose cake recipes that are denser and more stable, such as pound cakes or mud cakes. These types of cakes can withstand the weight of stacking and are less prone to tearing or crumbling.

6. Plan Your Path and Handle with Care

When transporting your cake, it's essential to plan your path and handle it with care to minimize any potential mishaps. Here are some tips to help you navigate the journey smoothly:

  • Before transporting your cake, plan the pathway you will take, both indoors and outdoors. Look for areas with extra shade and free from any obstacles that could cause accidents.
  • If you have a second person available, it's always helpful to have someone assist you in carrying the cake. They can provide additional support and ensure a steady grip.
  • Drive carefully and avoid sudden movements or sharp turns that could jostle the cake. Leave ample time for travel to avoid rushing, which can lead to accidents or mishandling of the cake.

7. Be Prepared for Emergencies

Even with all the precautions in place, emergencies can still happen. It's essential to be prepared and have a cake repair kit on hand to fix any unexpected mishaps. Here are some items you should include in your cake repair kit:

  • Extra frosting or icing for touch-ups.
  • Additional decorations, such as flowers or cake toppers, to replace any damaged or droopy ones.
  • Small tools, such as an offset spatula or piping bags, for quick fixes and adjustments.

Having a cake repair kit ensures that you can handle any last-minute emergencies and maintain the appearance of your cake, even in the face of unexpected challenges.

8. Enjoy Indoors or Under Protective Canopy

Once you have successfully transported your cake to the venue, it's crucial to set it up in an environment that will keep it cool and protected until it's time to serve. Here are some recommendations for displaying your cake:

  • If you're indoors, ensure that the temperature of the venue is around 72 degrees Fahrenheit (22 degrees Celsius). This will help maintain the stability and quality of your cake.
  • If the venue is outdoors, make sure there is a protective canopy or shade covering your cake. This will shield it from direct sunlight and minimize exposure to the heat.
  • Avoid placing your cake near sources of heat, such as grills or warm lamps, as these can cause the frosting to melt or soften.

By carefully selecting the display location and ensuring proper environmental conditions, you can keep your cake cool and intact until it's time to enjoy it.

9. The Importance of Buttercream Stability

Buttercream is a popular choice for frosting cakes, but it can be prone to melting in hot weather. To ensure the stability of your buttercream, follow these tips:

  • Use room temperature ingredients when making your buttercream. This helps the buttercream hold its shape better in warm temperatures.
  • Consider adding a small amount of shortening to your buttercream recipe. Shortening has a higher melting point than butter, providing more heat resistance and stability.
  • Chill your cake before serving, as this helps to keep the buttercream from sliding off and maintains its firmness.

By taking these steps, you can enjoy the smooth and stable consistency of your buttercream even in the hottest weather.

10. Additional Tips to Keep Your Cake Cool

Here are some additional tips and tricks to keep your cake cool in hot weather:

  • Use wafer paper or non-melting decorations, such as sugar flowers or chocolate decorations, instead of frosting sheets. These alternatives are more resistant to heat and won't melt or deform easily.
  • Avoid stacking your cake too far in advance. The weight of the upper tiers can compress the lower ones, leading to instability and potential collapsing.
  • If you're serving your cake outdoors, consider placing it on a cake stand with built-in cooling features. These stands are designed to keep the cake cool and fresh.
  • If you notice your cake starting to soften or melt, try placing it in the refrigerator or freezer for a short period to firm it up again. Be cautious not to leave it for too long, as extreme cold temperatures can affect the taste and texture.

By following these additional tips, you can enhance the cooling effect and stability of your cake, ensuring it remains a showstopper even in the hottest weather.


With the right preparation, planning, and proper techniques, you can keep your cake cool and prevent it from melting in hot weather. From choosing the right frosting to strategic storage and transportation, these tips will help you maintain the integrity and appearance of your cake, even in scorching temperatures. Whether you're attending an outdoor event or hosting a summer celebration, you can confidently showcase your beautifully decorated cake, knowing that it will stay cool, stable, and delicious until it's time to indulge. So go ahead, bake with confidence, and create unforgettable cake creations that can withstand any heatwave!
