🧁 How to Make 2-Ingredient Buttercream (Step-by-Step)
Step 1: Soften the Butter
Let the butter sit at room temperature until it’s soft but not melted. This ensures a smooth and airy whip.
Step 2: Whip the Butter
In a stand mixer (or with a hand mixer), beat the butter on medium-high speed for 3-5 minutes until it’s pale, fluffy, and smooth.
Pro Tip: Scrape down the sides of the bowl to ensure even mixing.
Step 3: Add Sweetened Condensed Milk
Gradually pour in the sweetened condensed milk while mixing on low speed. Once added, increase to medium and whip until fully combined and silky—about 2 more minutes.
Step 4: Use or Chill
Use immediately to frost your cake or cupcakes, or chill in the fridge for a firmer consistency.
