Pinch of Salt (optional): Helps balance the sweetness and enhances the depth of the coffee flavor.

How to Make Coffee Buttercream Frosting

Dissolve the coffee: In a small bowl, dissolve the instant coffee or espresso powder in hot water. Set it aside to cool slightly.

Cream the butter: In a large mixing bowl, beat the room-temperature butter using a stand mixer or hand mixer. Beat on medium-high speed for 3-4 minutes, until the butter is light, fluffy, and pale in color.

Add powdered sugar: Gradually add the powdered sugar, one cup at a time, mixing on low speed after each addition to prevent the sugar from flying out of the bowl. Once all the sugar is incorporated, increase the speed to medium and continue beating for 2 more minutes.

Add the coffee mixture and vanilla: Slowly add the dissolved coffee mixture and vanilla extract to the butter mixture. Beat on medium speed until fully combined and smooth.

Adjust the consistency: Add heavy cream or milk one tablespoon at a time, beating after each addition, until the frosting reaches your desired consistency. If the frosting is too thick, add more cream; if it’s too thin, add a bit more powdered sugar.

Final beat: Beat the frosting for an additional 2-3 minutes to ensure it is light, fluffy, and smooth.

Pro Tip: Creaming the butter properly at the start is essential for a light, fluffy texture. If the butter isn’t beaten long enough, the frosting may turn out dense.

Customization and Flavor Variations

Add chocolate: Mix in melted dark chocolate for a mocha twist.

Adjust coffee strength: Use more or less coffee depending on how strong you want the flavor to be. You can also substitute brewed coffee or espresso shots for instant coffee.

Try other extracts: Experiment with adding almond, peppermint, or hazelnut extract for a unique flavor combination.

Coloring tips: If you want to add color to your coffee frosting, use gel food coloring rather than liquid. Gel food coloring won’t affect the consistency of the frosting.

Common Problems and Fixes

Frosting too runny: This can happen if too much liquid is added. To fix it, add more powdered sugar a little at a time until the frosting thickens.

Frosting too thick: If the frosting is too stiff, add more heavy cream or milk, one tablespoon at a time, until you reach the desired consistency.

Butter too soft or melted: If your butter was too soft, the frosting might become greasy. Pop the frosting in the fridge for 15-20 minutes, then re-whip until smooth.

Storage Tips

At room temperature: The frosting can sit at room temperature for up to 8 hours if you're using it the same day.

In the refrigerator: Store in an airtight container in the fridge for up to one week. Before using, let it come to room temperature and re-whip to restore the smooth consistency.

In the freezer: You can freeze coffee buttercream frosting for up to 3 months. To thaw, transfer it to the refrigerator overnight, then allow it to come to room temperature before re-whipping.

FAQs

Can I make coffee buttercream frosting ahead of time?
Absolutely. You can make the frosting up to a week in advance and store it in the refrigerator. Just bring it to room temperature and re-whip before using.
