Chocolate Buttercream

3/4 cup Crisco
3/4 cup butter, softened (6 ounces, 1 & 1/2 American sticks)
1 1/4 cups cocoa
1 1/2 teaspoon vanilla
2 pounds powdered sugar
about 1/2 cup of water, give or take a little

(If you have a splash guard for your bowl, this is a good recipe to use it with.)

Mix the Crisco and butter at a slow speed until creamy.
Add the cocoa. Mix again until the cocoa is all incorporated.
Add the powdered sugar, vanilla, and most of the water. Beat at medium speed for a few minutes.
Test the spreadability and add water if necessary
