3-Ingredient Chocolate Orange Buttercream

I developed this Chocolate Orange Buttercream specifically to pair with my Chocolate Almond Cake. The buttercream complements that cake’s rich, not-too-sweet dark chocolate profile while adding a bright orange kiss in every bite.

Beyond that pairing, this buttercream works beautifully on many other cakes. Use it to add a grown-up chocolate-orange twist to orange poppy seed cake, orange olive oil cake, simple vanilla cupcakes, or a classic pound cake. It’s a surprisingly excellent match for a warm spice cake and transforms a chocolate loaf or brownie-style cake into a chocolate lover’s dream.

When you want a frosting that feels indulgent, slightly boozy, and sophisticated, this is the buttercream to reach for.

Ingredients Needed to Make this Recipe

You only need three main ingredients plus salt to make this luscious buttercream.

• Orange liqueur. Cointreau or any triple sec works well. Avoid stronger brandy-forward liqueurs if you want the orange flavor to stay clean and bright.
• Orange-flavored chocolate. Choose a high-quality dark chocolate with orange flavoring. Some bars include dried orange pieces or nuts, which add texture; choose a smooth orange-flavored chocolate if you prefer a perfectly silky buttercream.
• Unsalted butter. Use unsalted butter so you can control the final seasoning. If you use salted butter the frosting may taste too salty, especially given the amount of butter used.

Step-by-Step Photos and Instructions

1. Place the chopped chocolate and the orange liqueur in a double boiler.

A double boiler is a heat-safe bowl or small pan set over a larger pan of simmering water; the gentle steam melts the chocolate evenly without risking scorch or seizing.

2. Warm the water to a gentle simmer and stir the chocolate until about three-quarters melted. Remove from heat and keep stirring until fully melted and smooth.

3. Transfer the melted chocolate to a mixing bowl. With an electric mixer, beat in the butter one tablespoon at a time, adding slowly so the mixture emulsifies into a smooth buttercream.

4. Once all the butter is incorporated, add about 1/4 teaspoon of salt and beat on high for 2–3 minutes until the buttercream is light, glossy, and spreadable. Taste and adjust salt if needed.

The buttercream is now ready to frost cakes, cupcakes, or to be piped as desired.

What is a double boiler?

A double boiler is two nested vessels: a smaller pot or heatproof bowl set over a larger pan filled with simmering water. The steam from the water provides gentle, indirect heat that melts chocolate evenly without burning it.

If you don’t have a dedicated double boiler, you can create one with a small saucepan or heatproof bowl set over a larger saucepan, or rest a fine mesh strainer or bowl on a pot as shown in the photos.

How to Store and Freeze this Buttercream

Store Chocolate Orange Buttercream in an airtight container in the refrigerator for up to one week.

The frosting firms when cold and can be difficult to spread. About an hour before using, remove it from the fridge, let it come to room temperature, and then beat it briefly with an electric mixer to restore its silky texture.

You can also freeze the buttercream for up to three months in an airtight container. Thaw overnight in the refrigerator, then bring to room temperature and re-whip before using.
