Way too much milk!!!!!!
Try indydebi's recipe. If you like the butter flavor in your frosting. Use indydebi's recipe with butter. To use butter i replaced the 1/3 cup crisco with 1/3 cup butter. Works awesome, this is an amazing crusting BC recipe. You may add milk a little at a time after the amount given to get to the desired consistancy.
If you find it too sweet, add a little bit of salt, to cut the sweet flavor.
Indydebis Crisco-Based Buttercream Icing
* 1-1/3 cups Cricso
1/3 to 1/2 cup milk, depending on consistency needed
3 Tbsp powdered Dream Whip (*)
2-3 Tbsp clear vanilla, depending on your personal taste
2 lbs powdered sugar
(*) A powdered whipped topping mix made by Kraft Foods, usually found in the cake/sugar aisle in the grocery.
Theres no wrong way to mix this. I usually mix all but the powdered sugar for a minute or two, then gradually add the sugar, but the only reason I did this was to avoid the sugar-splash factor. The longer the mixer runs, the smoother it gets. Sifting the powdered sugar before blending helps with smoothness but is not necessary.
