How to Make Geometric Chocolate Cake Hearts

 This post may contain affiliate links. Please read my privacy policy for more details

These small individual geometric cake hearts are becoming so popular on social media at the moment and I think they may have become the new cakesicle! I love how sweet they are and how there are so many different ways to decorate them. You can then either add them onto your cakes or enjoyed them as a little cake treat. They also taste delicious. I am a huge fan of cakesicles and cake pops so these with their outer candy / chocolate shell filled with cake is just so yummy.

In this weeks video tutorial I am going to show you how I made my hearts in 3 different designs. There is a simple pastel pink heart decorated using pretty sprinkles by Happy Sprinkles, a black and white polka dot design and these pretty vintage rose inspired cake hearts.

Now before I talk about the cake hearts in more detail I am in love with these sprinkles. If you love them as much as I do, in this tutorial I used the Royal Glitter sprinkle mix and the Happy ever after mix by Happy Sprinkles.

3D chocolate Geometric Cake Hearts

For the cake hearts I used white candy melts and coloured them with the Colour Mill oil based colours which I got from The Cake Decorating Company. This was the first time I had used the Colour Mill colours and for colouring candy melts and chocolate they were amazing. The colours are really concentrated so you only needed a small amount, even for colouring the dots for the polka dot design.

You can buy candy melts pre- coloured but if you’re thinking of colouring your own chocolate or candy melts these give you so much more control and enable you to create the colours you want really easily. When colouring chocolate you will need to use an oil based or powdered colour else the colour will make the chocolate go hard and lumpy due to the water content of the colours.

Pink Rose Geometric Cake Heart design

I love them all, but I think out of the three if I had to choose my favourite design it would be the vintage inspired roses. I coloured some of my candy melts with the rose, raspberry and mint green Colour Mill colours and was able to use these as a paint inside my mould. In the tutorial you will also see this is the same technique I used for the polka dot design. I tested out different techniques and this method worked best as it made the design smooth and part of the outer shell. I tried painting the colour mill directly into the mould and it just didn’t dry, this also had the same effect if I tried painting onto the outside once they came out of the mould.

One little tip would be if you are using the candy melts as a paint to melt down a very small amount at a time as it will dry quite quickly, so once it become stiff just pop it into the microwave for a few seconds and it will become perfect for painting again.

Below you will find the full video tutorial showing how I made all 3 designs. I really hope you will find this tutorial useful and enjoy making your own version of these cake hearts. Let me know in the comments below which is your favourite design.

  1. I kept my hearts in an air tight container and when I checked them the next morning they were melted and broken. I’m not sure why.. or how to prevent this..
    PS they were hollow and I was going to decorate them the next day..

    1. Hi Alishka, I think the chocolate is getting too hot in the airtight container which is making the hollow shells melt. I would add them into the container with the lid off or so air can pass through.

  2. this video is helpful! I wondered how these geometric hearts would work filled with brownie. Would you use a similar technique? Hope you can help !

    1. Hi Nicole, I think they would be amazing with brownie inside as an alternative. I would use a similar technique, breaking them up to make them fit, and maybe adding some buttercream if you need the mixture to cling together better. Have fun trying them.

    2. That sounds like a great idea, Nicole. I’ve seen people doing it with a brownie and they add cream cheese to help the brownie crumbles stick together!

    1. Hi Amy, one pack of candy melts usually makes around 6 geometric hearts, but some packs of candy melts do differ in weight slightly.
