Coffee Jelly Ingredients

  • Coffee – I use fresh brewed coffee. You can use any coffee you like. Whether it is instant coffee powder, freeze-dried coffee, or even mixed sachets, this recipe will work. It is mostly important to use coffee you like the flavour of.
  • Gelatin – Gelatin is not only a key ingredient in this recipe but also beneficial for your hair, skin, and nails. I recommend using Locako Gelatin for the best results. Its superior quality ensures a better set and doesn’t have the off-putting odour of standard gelatin. Agar Agar (Kanten powder) can be used instead of gelatin for a vegan coffee jelly option. (see notes in the coffee jelly cubes recipe card).
  • Sweetener – I use Natvia Brown sweetener. You can use almost any sweetener you prefer. Adjust to your preferred level of sweetness.

How to Serve Coffee Jelly

Once the coffee jellies are set, you can enjoy them as is or get creative with toppings. Some serving suggestions include whipped cream, double cream, mascarpone, milk (keto milk), or condensed milk. You can find more ideas in the blog post above.


Feel free to experiment with different flavours and add-ins. For instance, you can try incorporating various extracts like vanilla or almond for a twist on the classic coffee taste.

Add chai tea for dirty chai jelly. Swap coffee for hot chocolate, tea, fruit tea, or even a tablespoon or two sugar-free caramel syrup for a caramel jelly.

Add 1-2 tablespoons of collagen peptides for an extra nutritional boost. Serve with ice cream, custard, or on top of porridge for an amazingly tasty breakfast.


Can I use instant coffee instead of freshly brewed coffee for Japanese coffee jelly?

Yes, you can use instant coffee as a substitute for freshly brewed coffee in this recipe. Simply dissolve the instant coffee in hot water according to the package instructions, and then proceed with the recipe as directed. Keep in mind that the strength of the coffee flavour may vary depending on the brand and type of instant coffee you use.

How long does Japanese coffee jelly need to set in the refrigerator?

Japanese coffee jelly typically needs to be set in the refrigerator for about 5 to 6 hours. The gelatin will solidify, giving the dessert its jiggly texture. It’s best to prepare the coffee jelly in advance, allowing enough time to chill and set properly before serving.

Can I customize the sweetness level of Japanese coffee jelly?

Absolutely! The sweetness level of Japanese coffee jelly can be adjusted according to your preference. If you prefer a sweeter dessert, you can add a sweetener of your choice, such as sugar, honey, or a sugar substitute like stevia, erythritol, or monk fruit. Alternatively, if you prefer a less sweet option, you can reduce or omit the sweetener altogether. Keep in mind that some sugar substitutes may react differently with gelatin, so it’s best to use a syrup-based sweetener for a smoother texture. Feel free to experiment and find the perfect sweetness level that suits your taste buds.

All the tips you need to make coffee jelly!
I use hot expresso coffee. If you have a pod machine, use 1 pod per cup measure. Alternatively, use enough instant coffee per cup measure.
Sweetener – I use Lakanto Brown sweetener. Xylitol or allulose is fine if you have it. You can reduce or eliminate the sweetener completely if preferred. I tend to go without as I find when you serve it with cream or condensed milk it is more than sweet enough.
Gelatin – If you’re looking for substitutes for gelatin in a coffee jelly, there are a few options to consider. (I also add a big scoop of Collagen Protein to add a bit of extra protein – this is purely optional). Gelatin is primarily used to set the jelly and create its jiggly texture. Here are some alternatives and how to use them:
1. Agar Agar: Agar agar is a plant-based gelatin substitute derived from seaweed. It sets at a lower temperature than gelatin and is suitable for vegetarians and vegans. To use agar agar in place of gelatin, follow these steps:
  • For 1 tablespoon of gelatin, use 1 teaspoon of powdered agar agar.
  • In a saucepan, dissolve the agar agar in the liquid (coffee in this case) over medium heat, stirring continuously.
  • Bring the mixture to a boil and simmer for a few minutes until the agar agar is fully dissolved.
  • Pour the coffee mixture into cups or molds and refrigerate until set.
The coffee jellies are a softer set than a gummy recipe. They more like a jello that can easily be served as is or with some cream or milk. You can add more gelatin or collagen peptides to make the jelly firmer. 
Fridge – for up to 5 days.
Freezer – yes, they can be frozen. When frozen it is best to use directly in a cup with some kind of milk. Use condensed milk, regular milk or keto milk .

    I’ve never seen a recipe like this before so I had to try it. Yes, it was fun to make keto coffee jellies and the kids even helped me. These little goodies are excellent on their own – but I must confess I added some to our ‘adult’ drinks on the patio last night.

    This is such a creative idea. I like your suggestion to how the coffee jelly can be served. Your presentation looks so refreshing. Mine turned out delicious too!

  16. Wendy

    How much instant coffee in place of Nespresso pods?

  17. Marilyn Brack

    In the picture where you are holding the jelly it looks like you have the jelly sitting on a very thin base of something. What is it? A wafer cracker maybe?

    1. Megan Mad Creations Hub

      Hi Marilyn, it is actually the fat from the butter. It looks kind of weird but tastes great with the jellies

  18. Mary Janke

    You had to mention turkish delight in the write up. Yummo. So I think I could do it with rose water. Any ideas? Love it !

  19. JC

    silly question, but are you using unsalted or salted butter in yours?

    1. Megan

      I just use salted butter. You get a bit of a fat crust but it is nice on the jellies. Ironically not weird at all

  20. Anonymous

    Hi Megan, can I ask why the nutritional value has Fat 0% when it has coconut oil and butter in it? Ty

    1. Megan

      Due to serving portions. the nutrition calculator does not show measure of less than 1g per portion. Basically like 40g fat / 60 serves so less than 1g per serve.
