Assuming you like to make your own frosting for this éclair cake, rather than utilizing locally acquired, attempt this formula: Utilizing an electric blender, beat together ½ cup mellowed margarine and ¼ cocoa powder until smooth. Gradually include 2 ½ cups powdered sugar and ½ tsp vanilla concentrate. Gradually pour in 2 tbsp milk and whip the icing until light and cushy. Spread over cake
This cake can be made ahead and frozen, or extras can be frozen as well. Cover the entire dish or extras firmly with cling wrap and store in the cooler for as long as 90 days. Permit the cake to defrost before serving.
