Share
By Makai Cake Decorating Supplies
In every cake business, there are times when a little buttercream, batter or sponge is left over.
Instead of throwing it away, why not turn it into something valuable?
Whether it’s a sweet gesture for your customer or a clever way to boost sales, using leftovers creatively is a win-win.
1. Make Mini Treats
Use leftover sponge and buttercream to make:
-
Cake jars – Layered sponge and cream in small jars
-
Cake pops – Bite-sized fun for kids and adults alike
- Mini cupcakes – Perfect for tasters or party bags
These are easy to batch and sell, or give as bonuses.
2. Offer a “Bonus Box”
Create a small treat box with a mix of mini items and offer it:
- As a surprise thank-you gift
- At a discounted price (“Today’s Extra Treats – £5”)
- On your social media story with limited availability
It shows generosity, avoids waste, and delights customers.

This small gesture can lead to glowing reviews and repeat orders.
Sometimes, a small sweet gesture goes a long way in keeping customers happy.
