DIY Marshmallow Cake Topper from Stelloberry Designs

It’s no secret that I have a soft spot for cake toppers and when it’s a cake topper that can be easily put together in 5 minutes, I’m all for it. So, I’m excited to have the lovely Steph of Stelloberry Designs sharing a super sweet and simple DIY – marshmallow cake toppers! They’re the cutest little toppers and are perfect for topping off cupcakes and when bunched up at different heights, would look totally sweet on your wedding cake!


Okay first thing’s first – I’d be lying through my teeth if I said I was a baker extraordinaire. I think ‘giving people grievous indigestion with my horrendous culinary skills’ is probably closer to the truth. But although I may lack ability in the kitchen I try to make up for it after the cooking’s done by making it look good. And if presentation’s as important as they always stress on cooking shows, then I’m halfway there right?

If you’re like me and you like to make your food pretty, then follow the instructions below to make yourself some cute cake toppers that are perfect for a wedding and edible to boot!


  • White marshmallows
  • Gel food colouring
  • Mini heart-shaped cookie cutters (I got mine here) <— insert link (
  • Skewers
  • A cake to decorate

Step 1

I used the second smallest cookie cutter in the set I had, which is around 2cm across at it’s widest point. Give your marshmallows a bit of a squash to make them flatter, then cut a heart shape out of each one using your cookie cutter.


Step 2

Place each marshmallow onto a skewer.

Step 3

Drop some gel food colouring into small bowls (sauce bowls work well), add water and briefly dip your marshmallows in to colour them. You don’t need much food colouring – one drop plus a few teaspoons of water creates a nice colour wash. Naturally, the more drops of colouring you add, the deeper and brighter the colour becomes.


Step 4

Leave your marshmallows to dry. Then stick them into your cakes and that’s it, you’re done!


There are a few ways you can use these little hearts – if you don’t fancy adding them individually to cupcakes you could bunch several together in differing heights on the top tier of your wedding cake, or you could also stick the skewers into drinks as an edible drink stirrer. Not bad for a five minute DIY hey?
