Customizable toppings – From cocoa to chocolate curls, it’s easy to finish beautifully.

What You’ll Need (Ingredient Highlights)

Instant coffee granules – The base of the flavor. Choose a rich, good-quality brand.

Gelatin powder – Helps the mousse hold its delicate structure.

Sugar – Either caster sugar or granulated white sugar works to sweeten the mix.

Cold whipping cream – Beaten to firm peaks to give the mousse volume and lightness.

Vanilla extract – Balances the bitterness of the coffee.

Cocoa powder or chocolate shavings – Optional, but add a touch of luxury to serve.

Pro Tips Before You Start

Don’t boil the mixture – High heat can damage the gelatin and overpower the flavor.

Use a rubber spatula – It helps dissolve any undissolved gelatin granules more gently.

Cool the syrup fully – Too warm and it’ll melt the whipped cream.

Whip cream to firm peaks only – Stop once it holds its shape—don’t overbeat.

Fold gently – Keep the airy texture by folding carefully from the bottom up.

How to Make Coffee Mousse

Step 1: Dissolve the Gelatin

Place water in a saucepan over low heat and sprinkle gelatin on top.

tir constantly with a rubber spatula until fully dissolved. Do not let it boil.

Step 2: Add Coffee and Sugar

Add the instant coffee granules and sugar.

Continue stirring over low heat until dissolved and combined.

Again, do not boil.

Step 3: Cool the Mixture

Transfer the coffee syrup to a large bowl.

Refrigerate for 15–20 minutes until cool (not cold)—a thick syrup that hasn’t set.

Step 4: Whip the Cream

In another bowl, whip cold whipping cream to firm peaks.

Stop when the cream holds its shape—do not overwhip.

Step 5: Combine Syrup and Cream

Stir vanilla extract into the cooled coffee syrup.

Add one-quarter of the whipped cream and mix in gently to loosen the syrup.

Step 6: Fold in the Remaining Cream

Add the second quarter of whipped cream and gently fold it in.

Repeat with the final two additions, folding gently each time to maintain volume.

The final mixture should be fluffy, light, and able to hold its shape.

Step 7: Chill and Serve

Spoon or pipe the mousse into small dessert glasses.

Refrigerate for at least 2 hours or overnight until fully set.

Step 8: Garnish and Enjoy

Just before serving, top with chocolate shavings or a dusting of cocoa powder.
