2 cups melted butter
3/4 cup white sugar
1 (3 ounce) package instant chocolate pudding mix
2 teaspoons vanilla extract
1 cup confectioners' sugar for dusting
Preheat oven to 350 degrees F (175 degrees C). Grease and flour two 9 inch round pans.
In a large bowl, beat butter and sugar together until smooth. Beat in pudding mix, vanilla extract and confectioners' sugar; beat until mixture is more or less smooth. Spread evenly into the prepared pans.
Bake in preheated oven for 45 minutes, or until a toothpick inserted into center of the cake comes out clean. Allow to cool.
