This whipped cream buttercream frosting is the lightest airiest and most delicious fluffy white frosting you will ever find: it's buttercream without butter. This crisco shortening- based buttercream icing is very similar to grocery store bakery frosting. Everyone who has ever tried it loves it and agrees it's "not too sweet"! Bonus: you can also make it into CHOCOLATE frosting!
Add shortening to large bowl and gradually add powdered sugar. Beat with stand mixer for about 5 minutes until mixture is very creamy and fluffy. Set this aside.
In a very clean bowl mix dry ingredients. Add boiling water and immediately beat with mixer on high speed. Beat until stiff peaks form, about 8 minutes. When mixture begins to get stiff add flavoring. * you can use a hand mixer for this part
Combine both mixtures and beat together for another 8 minutes with stand mixer.
When finished, use a rubber spatula to down beat a little to remove some of the air bubbles. Frosting will be very light and creamy. Cover. ***DO NOT REFRIGERATE. Can be stored for up to 2 months at room temperature (I keep it in the pantry).
