How to Make Swiss Iced Coffee with Egg and Brandy

If you’ve ever wanted a sweet, creamy, and surprisingly satisfying iced coffee that breaks the rules — think egg yolk, liqueur, and ice cream — then Swiss iced coffee might be your next obsession. It’s not your usual espresso-based drink. It’s a layered, old-school treat that combines strong coffee flavor with custardy richness and a boozy kick.

To make traditional Swiss iced coffee, you’ll need just one egg yolk, ½ fluid ounce of honey, ⅓ fluid ounce of brandy, a dash of cinnamon, one scoop of chocolate ice cream, chilled sweetened iced coffee, whipped cream, a few coffee beans for garnish, and crushed ice. That’s it — 8 ingredients, bold flavor.

What Is Swiss Iced Coffee?

Swiss iced coffee isn’t a typical cold brew or espresso shake. It’s a blended-style coffee drink that originated as a rich, indulgent way to enjoy coffee cold. Unlike American iced coffee or Vietnamese iced coffee, it uses raw egg yolk, sweetener, alcohol, and sometimes ice cream to create a thick, dessert-like texture. It’s sweet, aromatic, and surprisingly balanced — if made right.

Why Add Egg Yolk and Brandy?

Egg yolk adds a silky, custard-like mouthfeel and boosts the coffee’s body. When whisked properly with sweetener, it creates a frothy, creamy texture without dairy. Brandy, meanwhile, contributes a gentle warmth and depth. But both require care: too much brandy overwhelms the coffee, and egg yolk can taste overly eggy without the right spices. That’s where cinnamon comes in — just a pinch cuts through the richness and tones down any raw egg smell.

Key Ingredients & Measurements

• 1 egg yolk
• ½ fluid ounce (1/2OZ) honey
• ⅓ fluid ounce (1/3OZ) brandy
• A small pinch of cinnamon
• 1 scoop of chocolate ice cream
• Sweetened iced coffee (quantity: enough to blend well)
• Whipped cream (to garnish)
• A few whole coffee beans (for garnish)
• Crushed ice

How to Make Swiss Iced Coffee — Step by Step

Start by placing the egg yolk in a mixing bowl or blender. Add the ½OZ of honey, followed by the ⅓OZ of brandy. Sprinkle in a small amount of cinnamon. Then, add one scoop of chocolate ice cream. Pour in a suitable amount of pre-sweetened iced coffee — just enough to achieve a smooth, pourable consistency. Mix or blend everything thoroughly until fully combined and frothy. Once smooth, pour the mixture over a glass filled with crushed ice. Top with a swirl of whipped cream and garnish with a few coffee beans.

Flavor Profile & Texture

The result is a thick, dessert-like coffee drink: creamy from the egg and ice cream, sweet from the honey, aromatic with cinnamon and coffee, and lightly spiked with brandy. It’s indulgent but not heavy, sweet but balanced, cold but deeply flavorful.

Common Mistakes to Avoid

• Using too much brandy — it should be ⅓OZ or less to avoid overpowering the coffee.
• Skipping the cinnamon — it’s essential to reduce the raw egg aroma and balance sweetness.
• Not using sweetened iced coffee — the base needs to be already sweetened for proper balance.
• Over-blending — mix just enough to combine; don’t turn it into foam.

Frequently Asked Questions

Can I use a different liquor instead of brandy in Swiss iced coffee?

No, the recipe specifically calls for ⅓ fluid ounce of brandy. Substituting with other liquors like rum or whiskey will change the flavor profile significantly. Brandy provides a particular warmth and depth that pairs well with coffee and egg yolk without being too harsh.

Is it safe to consume raw egg yolk in coffee?

Yes, in small amounts and when mixed well with other ingredients like honey and alcohol, raw egg yolk is generally considered safe for most healthy adults. However, if you’re concerned about salmonella, use a pasteurized egg yolk or skip it altogether.

Can I make Swiss iced coffee without ice cream?

You can, but the texture will be thinner and less creamy. The chocolate ice cream adds both sweetness and body, making the drink richer. Omitting it means relying more on the egg yolk and honey for texture.

What’s the best coffee to use for the iced coffee base?

The original recipe doesn’t specify the coffee type, but a dark or medium-dark roast works best to stand up to the sweet and boozy layers. A strong brewed coffee, chilled and sweetened, is ideal for balancing the other flavors.

How do I get the whipped cream to sit nicely on top?

Use a spoon or piping bag to add a swirl of whipped cream on top after pouring the drink. Add coffee beans while the cream is still fresh. Avoid mixing the cream into the drink — it’s meant as a garnish.
