It's good, somewhat buttery, definitely not very sweet, which I think is why we like it. I like it best when the cake is cold because it has a real texture to it- firm but not hard. When it's room temp it's soft/fluffy. Off the top of my head (because I am DEAD TIRED from this weekend and too lazy to get up and find the recipe), I want to say it's 2c milk, 1/4c flour, pinch of salt. Mix together until smooth and then heat, with stirring, until it gets very thick and bubbles a little. Refrigerate until cold. Cream together 1c crisco and 1c butter, then add 1t vanilla and 2c confectioners sugar. When this is creamed, cream it into the pudding mixture. I use my hand mixer to do all this.
I know that a stick of butter is a half-cup, and four sticks make a pound and all that. I looked at the butter wrapper and it's marked at 1/2, with an arrow, and then another arrow with another 1/2. Apparently this marks off half of a stick, and I just had a brain fart and thought that was 1/2 cup and then 1c. DUH. Anyhow, glad I finally figured it out and was able to make the frosting. At one point DD said to go ahead and use buttercream, but I know she doesn't like buttercream very much, and I'm pretty intimidated by the buttercream made with a syrup, so... Anyhow, wedding cake was beautiful, a big hit, and it was exactly what DD wanted for her wedding dessert!
