Description

Lemon buttercream frosting made with a classic American-style base and flavored with homemade lemon curd. (Yields enough to frost a 6-inch layer cake or decorate about 10 cupcakes)

Ingredients

  • 200 g (1 ¾ sticks) unsalted butter – very soft
  • 350 g (2¾ cups) powdered sugar, sifted
  • 80 ml  (⅓ cup) heavy cream
  • 1 teaspoon vanilla extract
  • 100 g (⅓ cup + 1 tbsp) homemade lemon curd 

Instructions

Make the lemon curd

  1. Start by preparing a half batch of my homemade lemon curd recipe to get about 100 g (roughly ⅓ cup + 1 tbsp) — just the right amount for this frosting.
  2. Let it cool completely before adding it to the buttercream.

Make the buttercream

  1. Place the softened butter in the bowl of a stand mixer fitted with the whisk attachment. Whip on high speed for 5 to 7 minutes, until very pale and fluffy.
  2. Add the sifted powdered sugar in two additions. Mix slowly at first to avoid a sugar cloud, then increase the speed to fully incorporate.
  3. Next, add the vanilla extract and heavy cream. Whip again until the frosting is light, smooth, and creamy.
  4. Finally, add the cooled lemon curd and whip for another 2 minutes, until the frosting is silky and evenly mixed.
  5. Finish by mixing on low speed to smooth out the texture and remove air bubbles.
  6. Use right away, or cover with plastic wrap pressed directly on the surface and refrigerate until ready to use.

Equipment

Notes

Storage: Store in the fridge for up to 5 days in an airtight container, with plastic wrap pressed directly onto the surface.

Tips:

  • Use very soft butter for a smooth texture.
  • Sift the powdered sugar to avoid lumps.
  • Add the lemon curd once fully cooled to keep the frosting stable.
  • Mix on low speed at the end to smooth out the buttercream.
  • Let it sit at room temperature for about 30 minutes before using.
  • If it firms up too much, give it a quick whip to bring back the creamy texture.
  • For best accuracy, use a kitchen scale instead of measuring cup
