Kahlua Buttercream Frosting
Ingredients
Method
Step 1: Whip the Butter Until Light
Add the softened butter to a large mixing bowl. Using a stand mixer with a paddle attachment (or a hand mixer), beat on medium speed for about 2–3 minutes. You’re looking for a pale, airy texture—this is your base for ultra-smooth frosting.
Step 2: Create the Coffee-Kahlua Blend
In a separate small bowl, mix the espresso powder with the heavy cream and Kahlua. Stir until fully dissolved.No granules allowed—this step guarantees a smooth, even coffee flavor throughout.
Step 3: Add the Sugar Gradually
Lower the mixer speed and slowly incorporate the powdered sugar, about one cup at a time. Pause to scrape the bowl as needed. Once fully combined, increase speed to medium-high and whip for 2 minutes. This builds structure and gives your frosting that dreamy, fluffy body.
Step 4: Flavor It Up
Pour in the espresso mixture, vanilla extract, and a pinch of salt. Beat again for 2–3 minutes until everything looks silky and holds soft peaks. If the frosting feels too thick, add a splash of cream (one teaspoon at a time) until it spreads easily.
Step 5: Taste & Customize
Give it a quick taste test. Want it bolder? Add a little more Kahlua or espresso. Prefer it sweeter? Mix in extra powdered sugar. This is your moment to make it exactly how you like it.
