"This is the same recipe my Taught me 35 years ago. However, instead of the above ingredients, she taught me to use the actual cake batter that had been made and bring to a slow boil. It thickened and if your batter was say lemon the flavor came through. After all the batter is all of these ingredients. Has anyone ever done this. It's more like a curd glaze maybe...it was a sticky frosting not fluffy tho."
