Mary Berry Buttercream Icing Ingredients
A classic, foolproof frosting for all your baking needs.
- 250g (approx 1 cup or two sticks) unsalted butter, softened
- 500g (4 cups) icing sugar (confectioners’ sugar), sifted
- 2-3 tbsp milk (preferably whole milk)
- 1½ tsp pure vanilla extract
How To Make Mary Berry Buttercream Icing
Simple steps for a perfectly smooth and fluffy buttercream.
- Cream the Butter: In a large bowl or the bowl of a stand mixer, beat the softened butter on medium-high speed for 2-3 minutes, until it is very pale, creamy, and fluffy.
- Add the Sugar: Reduce the mixer speed to low and gradually add the sifted icing sugar in a few batches, mixing until it is just combined. Scrape down the sides of the bowl.
- Add Flavor and Liquid: Add the vanilla extract and 2 tablespoons of the milk.
- Whip Until Fluffy: Increase the mixer speed to medium-high and beat for another 3-5 minutes, until the buttercream is incredibly light, airy, and smooth. If the icing is too stiff, add the remaining tablespoon of milk to reach your desired consistency.

Recipe Tips
For the smoothest, most delicious buttercream every time.
- How do you get buttercream perfectly smooth and not grainy? There are two secrets. First, always use properly softened, room temperature butter. Second, you MUST sift your icing sugar. This removes any tiny lumps and is the key to a silky, non-gritty texture.
- Why beat the butter first? Whipping the butter on its own until it’s pale and creamy is a classic Mary Berry tip. This step incorporates air into the butter, which is the foundation for a light and fluffy frosting, rather than a dense, heavy one.
- Can I use a different butter to unsalted? It’s best to use unsalted butter so you can control the salt content yourself. If you only have salted butter, you can use it but omit any extra salt you might add.
- How do I get the right consistency for piping? The consistency can be easily adjusted. If your buttercream is too stiff to pipe easily, add more milk, just a teaspoon at a time, until it loosens up. If it’s too soft or runny, beat in a little more sifted icing sugar until it thickens.

Keeping your frosting fresh and ready to use.
- Room Temperature: The buttercream can be stored in an airtight container at room temperature for up to 2 days.
- Refrigerate: For longer storage, keep it in an airtight container in the refrigerator for up to a week.
- Freeze: Buttercream freezes exceptionally well for up to 3 months.
- Re-whipping: After being chilled or frozen, the buttercream will be very hard. Let it come back to room temperature on the counter, then re-whip it with an electric mixer for a few minutes to restore its light and fluffy texture before using.
