Instructions
- Preheat oven to 350 degrees F.
- Beat the egg whites and when soft peaks begin to form, gradually beat in about half the sugar and set aside.
- (Tip: If using an electric mixer, use the lowest speed possible; high speeds break down the egg protein and don't get job done much faster.) In a separate bowl, beat yolk and butter; gradually add the remaining sugar and when well combined add the remaining ingredients, beating until smooth.
- Fold the egg whites into the cake mixture with a whisk or spatula, and pour into a non reactive 8x8 baking pan that has been sprayed or buttered.
- Set the pan with the cake in a larger pan; pour hot water in the larger pan half way up the sides of the cake pan and carefully place in the oven.
- Bake for 45 minutes until top is lightly browned.
