8Oz(226g) full-fat brick-style cream cheese*, room temperatureNOT the spread
4Cups(480g) powdered sugar
1 1/2tsplemon juice
Pinch of salt, or to taste
Instructions
In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and cream cheese together on medium-high speed until light and creamy (no lumps), about 5 minutes, scraping down the bowl and paddle as needed.
Add the powdered sugar a few cups at a time and mix on low speed until combined, scraping down the bowl and paddle between additions. Add the lemon juice and salt and continue mixing on low speed until fully combined and smooth.
Notes
*It’s very important to use full-fat brick-style cream cheese in the lemon cream cheese buttercream recipe (I use Philadelphia brand), not the spread or low-fat variations. The spreadable kind and reduced fat versions contain much more water content and will add too much liquid to the frosting, making it impossible to work with. If you don’t have access to brick-style cream cheese, I recommend trying mylemon buttercream as an alternative.Yield: This buttercream makes enough to:
Frost 15-20 cupcakes with a piping bag
Fill and crumb coat a three-layer 6-inch cake or two-layer 8-inch cake. To have enough for frosting and decorating as well, double the recipe.
To Make Ahead: This lemon cream cheese buttercream can be made ahead and stored in an airtight container in the refrigerator for up to two weeks. When you’re ready to use it, bring it back to room temperature and re-mix it with your stand mixer on low speed until it’s smooth and uniform.
