How to Make Coffee Ice Cream at Home

When the heat hits, nothing beats a scoop of cold, creamy coffee ice cream—except maybe making it yourself with real espresso and just a handful of ingredients. This isn’t a store-bought imitation. It’s a proper custard-based coffee ice cream with real depth, using espresso or instant coffee powder, egg yolks, sugar, cream, and a touch of Baileys. Here’s how to do it right, step by step.

To make enough coffee ice cream for several people, you’ll need: 2 egg yolks, 30g caster sugar, 15ml Baileys, 1g instant coffee or 40ml espresso, 100ml heavy cream, plus 2 egg whites and 20g sugar. That’s ten times the original single-serving quantities shown in the photos. Total prep and freeze time is around 3 hours.

What You’ll Need: Ingredients Breakdown

This coffee ice cream is built on a classic French custard base, lightened with whipped egg whites and cream. Every ingredient has a role:

• 2 egg yolks – for rich custard base
• 30g caster sugar – sweetens the yolks
• 15ml Baileys (Irish cream liqueur) – adds depth and alcohol note
• 1g instant coffee powder OR 40ml fresh espresso – the coffee flavor
• 100ml heavy cream – for texture and richness
• 2 egg whites – to add lightness and volume
• 20g caster sugar – to sweeten and stabilize the meringue

The quantities listed are scaled up to serve multiple people. The original test used much smaller amounts, pictured in the photos.

Step-by-Step: How to Make It

1. Separate the Eggs

Start by separating 2 eggs, placing the yolks in one bowl and the whites in another. You’ll use them at different stages.

2. Make the Coffee Custard Base

To the egg yolks, add 30g sugar, 15ml Baileys, and either 1g instant coffee or 40ml freshly brewed espresso. Whisk to combine.

Place this mixture over a bowl of hot water (not boiling) and whisk continuously until it becomes pale, fluffy, and roughly doubles in volume. This step cooks the yolks gently and builds airiness. Once thickened, chill this custard base in the fridge.

3. Whip the Egg Whites to Stiff Peaks

In a clean, grease-free bowl, beat the 2 egg whites along with 20g sugar until they form stiff peaks—the volume should increase by more than 5 times and hold firmly when the bowl is turned upside down. Chill the meringue once done.

4. Whip the Cream

Using the same or a different chilled bowl, whip 100ml of heavy cream with an electric mixer until it holds stiff peaks—this means it should stand upright when the whisk is lifted. Don’t overwhip. Keep this refrigerated too.

5. Combine Everything

Use a rubber spatula to gently fold the chilled custard base into the whipped cream until smooth. Then fold in the stiff egg white meringue. Be careful not to deflate the mixture—fold gently but thoroughly.

6. Freeze

Transfer the combined mixture into a container and freeze for at least 3 hours, or until firm. After that, it’s ready to scoop and serve.

The photos show the process scaled up to 10x the original recipe, suitable for serving a group. The individual serving version used much smaller measures.

Why This Works

This coffee ice cream combines custard richness (from egg yolks and sugar cooked gently with coffee and Baileys), airy volume (from whipped egg whites), and luxurious texture (from whipped cream). The alcohol in the Baileys helps keep it smooth while lowering the freezing point slightly for easier scooping. The espresso or coffee powder provides a clear, strong coffee flavor without bitterness.

Frequently Asked Questions

Can I use fresh espresso instead of instant coffee?

Yes. The recipe works with either 1g of instant coffee or 40ml of freshly brewed espresso. Both deliver a strong coffee flavor. Use what you have on hand—just don’t reduce the amount or the coffee taste will be too weak.

Do I really need to whip the egg whites separately?

Yes. Whipping the egg whites to stiff peaks and folding them in adds lightness and volume to the ice cream. Skipping this step will result in a denser, custardy texture but less airiness.

Can I skip the Baileys?

Yes, but the Baileys adds a subtle creaminess and depth that complements the coffee. If you omit it, increase the sugar slightly or replace it with another liqueur like Kahlúa for a similar effect.

How long does it keep in the freezer?

Properly stored in an airtight container, this coffee ice cream will keep for up to 2 weeks. It may start to absorb odors from the freezer, so wrap or seal it well.

Is it safe to eat raw eggs in this recipe?

This recipe uses cooked egg yolks (tempered over hot water) but raw egg whites. If you’re concerned, use pasteurized eggs or a pasteurized egg white product. The custard base is cooked gently via the water bath method.

Can I use a different alcohol?

Yes. You can substitute Baileys with other coffee-friendly liqueurs like Kahlúa, Tia Maria, or even a splash of rum or vodka. Adjust to taste, but keep the quantity similar for texture balance.
