1-First Steps: Softening and Mixing Basics Begin by softening the butter at room temperature for about 15 minutes; this makes it mix smoothly. Once it’s ready, beat the 1 cup of softened unsalted butter on low to medium speed for 30 seconds to 1 minute until it’s nice and creamy. Then, sift your 3 cups of powdered sugar to avoid lumps and add it gradually while mixing on the lowest speed to prevent any mess. After that, crank up to medium speed and mix for about 2 minutes to blend everything well. Now, stir in the 1 teaspoon of vanilla extract and 2 teaspoons of cream or milk, then beat on medium-high speed for 1 to 2 minutes until stiff peaks form. This step ensures your frosting holds its shape without being runny, giving you that firm texture ideal for decorating.
