They should achieve a creamy texture with quite a thick consistency. The longer and faster the butter and sugar are creamed the lighter the cake will be when cooked.","Add both eggs and mix well.","Add all the flour using a fine sieve from a height, adding air to the flour, and beat with wooden spoon in a circular motion, trying to incorporate as much air as possible.","Add any food coloring, flavoring etc. at this point. If you add liquid ingredients, add the same volume again of sugar-and-flour mix to compensate. If adding dry ingredients, ensure to use equal parts less flour than any extra ingredient added.","Grease 1–2 cake pan(s) with butter. You may wish to use a springform pan for this recipe.","Scrape the batter into the pan(s). If using two pans, try to ensure that both tins have an equal amount of batter in them and that both are not more than ¾ filled.","Put the cake tins into the oven and leave them for approximately 10 minutes before checking them. The cooking time should eventually reach around 15 minutes: keep checking them regularly after about 8 minutes since ovens vary.","Turn the cake out onto a wire rack to cool.","If assembling 2 layers of cake, turn one of them upside down and spread the jam or buttercream onto its base. Stick the other cake top-side up onto the upside-down cake.","Dust the cake with icing sugar using a fine sieve."],"categories":["Cake recipes","Recipes for cake","English recipes","Baking recipes","Recipes using butter","Recipes using egg","Dessert recipes","Recipes using baking powder","Recipes using superfine sugar","Recipes using powdered sugar","Recipes using self-raising flour","Recipes using food coloring","Recipes using fruit preserves","Recipes using margarine"],"prep_time_minutes":null,"cook_time_minutes":null,"total_time_minutes":null,"servings":null,"yield_text":null,"difficulty":"easy","source_name":"wikibooks","source_url":"https://en.wikibooks.org/wiki/Cookbook:Sponge_Cake_I","source_ref":"4516957","authors_url":"https://en.wikibooks.org/w/index.php?title=Cookbook:Sponge_Cake_I&action=history","license":"CC BY-SA 4.0","license_url":"https://creativecommons.org/licenses/by-sa/4.0/","extraction_confidence":null,"content_hash":"7ec2c9a083c8609aa2334da46bc19b9bd897a844b543c8440f874d20b09899ba","created_at":"2026-08-02T14:43:23Z","updated_at":"2026-08-02T14:43:23Z","notice":null,"url":"https://recipecontextprotocol.com/recipes/sponge-cake-i"}
