This recipe is supposedly for Devil Dog cream filling but it tastes just like a Hostess Cupcake cream filling also. Hope it works for you.

1/4 cup melted butter
Add 3 tablespoons of flour
Stir to paste

Add 3/4 cup milk
Cook until thick. It will turn thick like pudding.

Make sure it is cool before adding
3/4 cup sugar
1/2 cup Crisco
1 1/2 tsp vanilla
Beat with egg beater until creamy.

Note: By itself, this wasn't all that sweet tasting but put between 2 devil's food cake layers and frosting, it worked out great. Received many compliments.
