A luscious old fashioned cake filling from the US Regional Cookbook, Chicago Culinary Arts Institute, 1947. Enough filling for two 9-inch layers. Cooking time is approximate.
- Mix sugar and cornstarch together and add to egg yolk.
- Stir in sour cream and cook in double boiler until it coats the spoon.
- Add flavoring, stir well.
- Let cool to room temperature before assembling cake.
Fabulously easy! I used this to fill a two layer chocolate cake by substituting vanilla for the lemon extract.
