This lemon buttercream frosting has serious flavor to it! It's made with both lemon juice and lemon zest for that extra flavor punch. This icing is easy to make in just 5 minutes and perfect to add to all your favorite Spring desserts like lemon curd cake!
In the bowl of a hand or stand mixer fitted with a paddle attachment, combine the 3 1/2 cups confectioners sugar and 1 cup softened butter. Mix on low speed working up to medium as the sugar combines with the butter. About 2-3 mins.
Stop the mixer and scrape down the sides. Add the 2 tsp lemon zest and lemon juice.
Turn the mixer back to low speed and add 1 tbsp milk, and the pinch of salt if using. Mix on medium for 3 minutes and enjoy!
Notes
The salt can bring out the flavor a little bit more but you dont have to use it if you dont want to. If you use bottled lemon juice the flavor wont be as pronounced.If you want to use lemon extract leave out the zest and only use 1/4 tsp to start.
