Ingredients Needed for Mary Berry Buttercream

  • Unsalted butter: 250 grams (about 1 cup), softened to room temperature
  • Powdered sugar: 600 grams (about 1.3 pounds), sifted for smoothness
  • Milk: 3 tablespoons, preferably whole milk for richness
  • Vanilla extract: 1 teaspoon for a hint of vanilla flavor


  • Large mixing bowl
  • Electric mixer or a whisk if mixing by hand
  • Spatula for scraping the sides of the bowl
  • Sifter for the powdered sugar
  • Measuring spoons and scales

Instructions to Make Mary Berry Buttercream

Step 1: Prepare Your Ingredients

Ensure your butter is at room temperature before you begin. This makes it easier to beat and combine with other ingredients, resulting in a smoother buttercream.

Step 2: Beat the Butter

In your large mixing bowl, beat the butter using an electric mixer on medium speed until it is pale, fluffy, and smooth, about 3 to 5 minutes. This process is crucial as it incorporates air into the butter, giving the buttercream its light texture.

Step 3: Gradually Add Powdered Sugar

Gradually add the sifted powdered sugar to the butter, one cup at a time. After each addition, mix on low to incorporate the sugar into the butter fully. This step should be done slowly to avoid the powdered sugar from clouding up and to help achieve a smooth consistency.

Step 4: Add Milk and Vanilla

Once all the sugar has been incorporated, add the milk and vanilla extract. Beat the mixture on high for an additional 2 minutes. This not only helps to thin the buttercream to a spreadable consistency but also adds lightness.

Step 5: Adjust Consistency

If your buttercream is too thick, add milk, one tablespoon at a time, until the desired consistency is reached. Conversely, if it is too thin, add more sifted powdered sugar to thicken it.

Step 6: Use or Store

Use the buttercream immediately or store it in an airtight container in the refrigerator for up to one week. Before using refrigerated buttercream, let it come to room temperature and give it a good stir to restore its creamy texture.
