In a stand mixer with the paddle attachment, cream butter and shortening on medium-high until fully combined and fluffy, about 3 minutes.
With the mixer on low speed, add lemon juice and salt.
Slowly add confectioners' sugar, one cup at a time. Add meringue powder. (The mixture will appear dry.)
Pour in milk. Turn the mixer up to medium-high (or high) and beat until light and fluffy, approximately 5 to 8 minutes. If the buttercream is too dry, add more milk, 1 tablespoon at a time, and mix on low speed until you reach your desired consistency.*
Place directly into piping bags and seal with a rubber band. Can be stored in piping bag until ready to use, up to 3 months.
Notes
*For extra smooth frosting with fewer air pockets, add buttercream to a food processor ½ batch at a time. Process for 3-5 minutes on high, or until frosting appears smooth and creamy like ice cream.
