Mary Berry Lemon Buttercream Recipe
Are you looking for the perfect topping for your cakes? This Mary Berry Lemon Buttercream Recipe is the answer. It is light, fluffy, and full of zingy flavor. Mary Berry is the queen of baking for a reason.
Ingredients
- Unsalted Butter: 250g must be very soft at room temperature
- Icing Sugar: 500g sifted to remove all lumps
- Fresh Lemons: 2 large you will need the zest and juice
- Milk: 1-2 tablespoons only if needed for a softer texture
- Yellow Food Coloring: 1 drop optional, for a brighter look
Instructions
Soften the Butter
- Place your room-temperature butter into a large bowl. Beat it with an electric mixer for three minutes. It should look pale and very creamy. Soft butter is the secret to a smooth frosting.
Sift the Icing Sugar
- Sift your icing sugar into a separate bowl. This prevents any tiny lumps from ruining your smooth buttercream. Never skip this step if you want a professional finish for your cakes.
Add Sugar Gradually
- Add half of the icing sugar to the beaten butter. Mix on a low speed at first so the sugar doesn't fly everywhere. Once combined, add the remaining half and beat again until fluffy.
Zest and Juice the Lemons
- Grate the zest of two lemons directly into the bowl. Squeeze the juice into a small cup and remove any seeds. The fresh zest provides the most intense citrus aroma and flavor.
Combine the Citrus
- Add two tablespoons of the fresh lemon juice to the mixture. Beat on high speed for another two minutes. The frosting will become light, airy, and very easy to spread or pipe.
Adjust the Consistency
- Check the texture of your buttercream. If it is too stiff, add a splash of milk. If it is too runny, add a little more icing sugar. It should be firm but spreadable.
Notes
- Use Real Butter: Never use margarine from a tub. Real block butter gives the best flavor and stability.
- Room Temperature: Ensure your butter is soft before starting. Cold butter will create greasy lumps that are hard to remove.
- Lemon Curd Swirl: For an extra treat, marble some lemon curd into the buttercream at the very end.
- Orange Version: You can swap lemons for oranges or limes. This creates a different but equally delicious citrus frosting.
- Extra Zesty: If you love a sour kick, add a tiny pinch of citric acid to the mix.
