Aunt Margaret Harsen McCarthy, circa 1952
But the really important thing about Aunt Mar was her sponge cake recipe. As far back as I can remember, on all of our birthdays, we waited with baited breath for her to arrive with our birthday cakes. We loved them. My aunt was sweet enough to write down all her recipes when I married and the birthday cake was among them. And yes, I continued the tradition and made the identical cake for each of my children until they were grown and gone. It is really a very basic recipe with old fashioned 7 minute frosting. Of course, the cake called for lemon flavoring which results in a slightly different flavor than other sponge cakes. I use extract in my recipe and had to adjust the amount as it is stronger than flavoring. It’s really not that unusual a sponge cake recipe but it does make a picture-perfect birthday cake- all that fluffy frosting. And when Aunt Mar added the birthday candles, we thought it was enchanting!

Aunt Mar’s Birthday Cake
Ingredients:
1 1/2 cups sugar
1 1/2 cups flour
6 eggs, room temperature
1 1/3 teaspoons cream of tartar
1/2 cup cool water
1/4 teaspoon salt
1 teaspoon vanilla
3/4 teaspoon lemon extract
Method:
Place room temperature egg whites in a bowl and beat until foamy. Add 3/4 teaspoon cream of tartar and beat until soft peaks. Slowly add 1/2 cup sugar and the vanilla, beat until stiff peaks and set aside.
In another bowl, beat yolks until lemon colored. Add lemon extract and the remaining sugar.
Sift the flour and the remaining cream of tartar. Beat the flour and cream of tartar into the egg/sugar mixture alternately with the cold water. Fold in egg whites carefully by hand and pour into an angel food cake pan. Bake 350° for 1 hour and cool upside down on a funnel.
Sift some confectioners sugar on a cake plate. Run a knife around the edge of the cake pan and around the center. The cake should release easily. Invert on the cake plate. (My aunt always served the cake top side down, but this is your choice.)
Frost generously with 7 minute frosting.

Seven Minute Frosting
Ingredients:
2 unbeaten egg whites, room temperature
1 1/2 cups sugar
5 Tablespoons cool water
1/4 teaspoon cream of tartar
1 1/2 teaspoons corn syrup
1 teaspoon vanilla
Method:
Place all ingredients except the vanilla in the top of a double boiler. Beat constantly with electric beater while it cooks for 7 minutes or until at least double in volume and holds stiff peaks. Remove from heat. Add vanilla. Beat again to mix.
