What Does Saiki K Coffee Jelly Really Taste Like?

Coffee Jelly Spoon


You can either serve the jelly cut up in cubes or shaped in a serving vessel. Since Saiki K’s coffee jelly is not cubed, we went for small mason jars.

The color of the jelly depends on the type of roast you use; it can be dark and dense like ours or paler. With the whipped cream on top, it reminds us of diner-style desserts!

And speaking of nostalgic desserts, this no-bake coffee fluff pudding should totally be up your alley too.


The coffee jelly has that characteristic coffee taste but is slightly diluted. Since we made it with sugar and topped it with whipped cream, it’s sweet, creamy, and just a little bitter.

You can make it sweeter by adding more sugar or make it completely sugar-free. However, don’t skip the whipped cream.

Coffee Variations

If you try to search for coffee jelly recipes, you’ll find out that everyone uses a different type of coffee. For example, the original Japanese recipe relies on canned instant coffee while the western world prefers espresso. There’s not a right or wrong choice, just different preferences.

Instant Coffee

Instant Coffee

Instant coffee comes up as a first choice since it’s the most convenient one of all. But it has the least amount of coffee flavor and aroma, so coffee lovers tend to avoid it.

However, it’s completely acceptable when making coffee jelly. The amount of caffeine per serving comes at approximately 30 mg.

Canned Japanese Coffee

Japanese Canned Coffee

Canned Japanese coffee(1) is another type of instant coffee. It’s available in Asian grocers or online retailers such as Amazon.

Always check the ingredients list to see if it comes with sugar since you might need to adjust the recipe accordingly. With canned Japanese coffee, a serving of coffee jelly will have 70 mg of caffeine.

Brewed Coffee

Brewed Coffee

Brewed coffee gives great flavor to your coffee jelly, but it can be a little mild for those who are big coffee lovers.

You can use any roast and brew method of your choice, a french press, Aeropress, or drip machine. The amount of caffeine comes at approximately 47 mg per serving.


Coffee Shot

Using espresso for your coffee jelly means you’ll have to dilute it. It’s too strong but the most flavorful type of brew.

If you decide to go with espresso, use ¾ cup espresso + 1 ¼ water. A single serving of the jelly will have around 95 mg of caffeine!

Dietary Variations

We’re aware that the Saiki K coffee jelly recipe is not a one-shoe-fits-all. Since many of the ingredients might not work with your dietary restrictions, we have a list of substitutes. You can still enjoy this fun anime dessert and stay true to your diet.

Creamer Contents

Caffeine Sensitivity

The caffeine content in the coffee jelly is significant. Therefore, if you suffer from caffeine sensitivity, opt for decaf coffee instead of regular coffee.

Decaf coffee still contains trace amounts of caffeine, but it’s minimal compared to the real deal. We don’t recommend using coffee alternatives like Dandelion Coffee or Lions Mane because it will alter the taste of the jelly.

Gelatin and whipped cream are not vegan-friendly. The best substitute for gelatin is agar powder. The ratios stay the same, as one tablespoon of agar replaces a tablespoon of gelatin.

The easiest way to replace whipped cream is to whip aquafaba – the water from canned chickpeas.


If dairy is your enemy, you can easily replace the whipped cream with vegan varieties. Even popular brands now carry dairy-free creams.

There are options for those suffering from lactose intolerance too! The cream doesn’t have to be made from plant milk to be lactose-free(2).

Coffee jelly can be made keto-friendly with some tweaks. First, use your own brewed coffee instead of instant coffee and sweeten it with Stevia.

For the topping, make your own cream by whipping heavy cream with no sugar. Agar is not only vegan but keto-friendly too, so use it as a substitute for gelatin.


Saiki K Coffee Jelly

More Questions

Does coffee jelly have caffeine?

The caffeine content of coffee jelly depends on the type of coffee used. With espresso, you’re looking at 95mg of caffeine per serving which is 1/4 of the daily recommended intake.

If you go for decaf, there will be trace amounts of caffeine in a single serving. Chose your type of coffee to regulate how much caffeine there will be in the final product.

How to make Saiki K Coffee Jelly?
