Ingredients for Coffee Frosting

- 2 Tablespoons instant coffee
- 2 Tablespoons very hot water (steaming works best)
- 1 cup (226 g) unsalted butter, softened (leave at room temperature for 30 minutes)
- 3 ½ cups (440 g) powdered sugar (sifted for smoother texture)
- 1 teaspoon vanilla extract
- ⅛ teaspoon table salt
Step-by-Step Instructions
- Dissolve the coffee: Place the instant coffee in a measuring cup and pour the hot water over it. Whisk until smooth. Let it cool completely (you can refrigerate it for faster cooling).
- Beat the butter: In a large mixing bowl, use an electric mixer to beat the softened butter until it’s smooth and creamy.
- Add powdered sugar: With the mixer on low speed, gradually add the powdered sugar, mixing until fully combined. Stir in the vanilla extract and salt.
- Incorporate the coffee: Gradually drizzle the cooled coffee mixture into the bowl while stirring. Mix until fully combined. Scrape the sides and bottom of the bowl to ensure everything is well incorporated.
- Use as desired: Spread or pipe the frosting onto your baked goods. Enjoy!
Perfect Pairings: What to Frost with Coffee Frosting
This rich and creamy coffee frosting is a dream on chocolate cake, cupcakes, or even brownies. For a delightful twist, try it on vanilla or caramel-flavored desserts. It also pairs beautifully with mocha cookies or as a filling for whoopie pies.
Storage Tips: Keep Your Frosting Fresh
Store your coffee frosting in an airtight container in the fridge for up to 5 days. If it hardens, let it sit at room temperature for 15-20 minutes, then give it a quick whip with a mixer to restore its creamy texture. You can also freeze it for up to 2 months—just thaw and re-whip before using.
Time-Saving Hacks for Busy Bakers
To speed up the cooling process for the coffee mixture, pop it in the freezer for 5-7 minutes instead of the fridge. If you’re in a rush, use cold brew concentrate instead of instant coffee—just skip the water step and add it directly to the frosting for a bold flavor.
Recipe Variations: Customize Your Coffee Frosting
For a decaf version, use decaffeinated instant coffee. Add a pinch of cinnamon or cocoa powder for a spiced or mocha twist. If you prefer a stronger coffee flavor, increase the instant coffee to 3 tablespoons and reduce the water to 1 tablespoon.
