Decorating & Delivering Cakes in Hot Weather

How to Decorate, Store, and Deliver Cakes in Hot Weather: Summer Tips for Bakers

It’s heating up over here in the UK, the warm weather is lovely for garden parties and weddings, but it can be stressful for us cake decorators. Buttercream softens, fondant sweats, and delicate decorations can wilt if you’re not prepared!

If you’re a cake decorator, home baker or baking business owner, summer can be a tricky season. Heat and humidity aren’t kind to buttercream, fondant, or delicate decorations. Whether you’re baking from home, running a cupcake business, or just decorating cakes as a hobby, knowing how to prep, store, and deliver cakes safely in warm weather is essential.

In this post I’m sharing my top tips from years of experience running Lady Berry Cupcakes, especially during the warmer months. You’ll also find a helpful checklist you can print or copy, edit for your customers when they collect or receive a cake order in hot weather.


Why Cakes Need Extra Care in Summer:

High temperatures can cause:

  • Buttercream to melt or slide off the cake

  • Fondant to sweat or crack

  • Decorations to wilt, especially sugar flowers or piped details

  • Cakes to collapse in transit if not chilled properly


Here’s how I handle cake decorating, prepping, storage, and delivery when the temperature rises and how you (or your clients) can keep your cake looking and tasting perfect after it leaves your kitchen.

Prepping Cakes for Hot Weather

  • Use stable buttercream: Swap out soft butter for a high-butterfat or shortening-based recipe if needed. As this will stabilise your buttercream will hold up better.

  • Chill between steps: Chill your cake between layers, crumb coat, and final coat to keep everything firm and workable.

  • Avoid cream cheese frosting: It softens quickly in heat. If needed, keep it for well-refrigerated cakes only.

  • Go light on dark colours: Deeply coloured fondant or buttercream (black, navy, red) can become sticky or stain easily in the heat.

    Staying cool is Key

  • Work in a cool space: Keep your kitchen as cool as possible. Close blinds, avoid ovens on unnecessarily, and use a fan (but not directly on the cake). I recently invested in an Air Cooling Fan for my kitchen Best purchase ever for the summer months!

    Here is why:

Helps set buttercream faster :A gentle fan can help crust buttercream quickly, making it easier to pipe details and handle cakes without smudging.

Reduces humidity in your workspace: Humidity can make fondant sticky or cause buttercream to melt. A fan improves airflow and can help reduce that clammy feeling.

Improves comfort during hot baking sessions: Ovens can heat up small kitchens quickly. A fan keeps you cooler, so you’re less tired or irritable on busy baking days.

Helps fondant figures dry faster: Airflow speeds up the drying of fondant and gum paste decorations, meaning you can work more efficiently.

Prevents sweaty cakes in summer: On humid days, condensation can form on cold cakes. A fan can help balance room temperature and avoid that sticky finish.

Cost-effective alternative to air conditioning: Fans are cheaper to buy and run, making them a budget-friendly way to keep your workspace more comfortable.

Improves air circulation in small home kitchens: Avoids stagnant, stuffy air (especially helpful when baking in small or enclosed spaces).

Can help keep flies away: The airflow from a fan can deter flies from landing on your beautiful bakes in summer.

Storing Cakes in Hot Weather

  • Keep cakes in the fridge until delivery or collection.

  • Don’t store near strong-smelling foods (like onions or garlic).

  • Use cake boxes that are tall enough to prevent decorations from being squashed.

  • Add a ‘best out by’ time if the cake will sit out on display for hours (especially for outdoor events).

Delivering Cakes Safely

  • Chill the cake before travel – it should be cold and firm.

  • Use a flat, non-slip surface in your vehicle – like a boot mat or shelf liner. Ideally in the foot well. Or a secure space in the boot where it cannot slide.

  • Drive with air-con on and avoid direct sun hitting the cake box. Black out blinds are great.

  • Allow extra time in case you need to park or carry the cake further to avoid heat.

Cake Decorating Tips for bAKERS iN Hot Weather

If you’re baking during a heatwave or warm spell, here’s how to prep your cakes to keep them stable:

🍰 Use a heat-stable buttercream – Choose a recipe with shortening or high-fat butter. Avoid soft, whipped frostings in summer.

🍰 Work in the coolest part of the day – Early mornings or late evenings are best if your kitchen gets hot.

🍰 Chill between stages – After stacking, crumb coating, and decorating, always pop the cake in the fridge to set.

🍰 Avoid soft fillings – Swap fresh cream or fruit curd for more stable options if the cake will be out of the fridge for long.

🍰Go easy on dark colours – Deep buttercream shades (black, red, navy) absorb heat and can stain or melt more easily.
