How to make wax melts with essential oils

These cheerful melts are an easy way to scent your space.

White wax melts on wooden table.

Wax melts make for a simple, effective alternative to candles.

Melts are easy to master, and this recipe allows you to make them in whatever size, shape and colour you prefer.

Most importantly, you can customise them with whichever essential oil, fragrance oil or blend you want.

Cheaper and simpler to make than candles, wax melts might just become your new favourite way to diffuse essential oils in your space.


  • 300g soy wax flakes
  • 40g essential oils

That’s it! You can also use wax dye in the colour of your choice if you’d like to customise your wax melts even further.

This isn’t essential however – your melts will smell just as nice either way.

This is a fully customisable recipe, and as such you can change the quantity of essential oil to make the scent of your wax melts stronger or more subtle depending on your preference.

You can use 40g of just one oil, or you can split that 40g between several.

You can also decide whether you would rather use essential oils or fragrance oils to scent your wax melts.

You will also need:

  • A glass jug
  • Silicone molds in your preferred shape
White oil burner.


  1. Melt the wax in a glass jug by placing in the microwave for thirty seconds. Take out the wax and stir, then place back in the microwave for a further thirty seconds. Repeat until the wax is melted. Take care not to overheat the wax, as if you do it will start to develop little white spots. These can make your wax melts look less professional, but they won’t affect the quality or scent of the wax melts overall.
  2. If you want to add a wax dye to your melts, then you should do that here. Otherwise, you’re ready to add the oils. When the wax has cooled slightly but is still not solidifying, add the essential oils and stir well.
  3. Pour the wax into the molds and leave in a cool place until the shapes have hardened. It’s usually better to leave them overnight. Don’t place the molds in the fridge, as the wax will crack if it gets too cold.
  4. Once the wax has hardened, remove from the molds. Your melts are now ready to use.

How to use:

In order to use your wax melts you will need a melt warmer.

Place 1-3 melts in the tray of your melt warmer, depending on your preferred length and duration of scent, and light below.

You can choose melts of the same scent or mix and match to get your ideal blend. Be careful never to touch hot wax. 

You can also place melts in drawers, cupboards and even shoes to keep them smelling fresh.
