Recipe from Susie Groesbeck...
This was always my favorite breakfast when my sisters and I slept over at our Aunt Susie's when we were little. They require an Ebelskiver pan and a little extra effort, but my kids think they are pretty special. We eat them plain and serve powdered sugar, jam and cinnamon and sugar on the side. The Danish serve these with sweetened lingonberries. You can also fill them with jam or diced apples with cinnamon and sugar. ***See the comments: Adding a few chocolate chips in the middle makes them irresistible!
5 eggs, separated
2 cups Bisquick baking mix
3/4 cup milk
Beat egg whites until stiff but not dry. In another bowl blend egg yolks, Bisquick and milk until smooth. Add a bit more milk if batter seems too firm. Fold in egg whites. Heat pan over medium heat. Butter each cup in pan or spray with non-stick cooking spray. Pour batter into cups to 2/3 full (I use a large cookie scoop to fill cups). Add a Tablespoon of jam or fruit filling, if desired. Cook until surface is bubbly and underside is light brown. Turn carefully with metal or wooden skewers or a toothpick. Cook on the other side until golden brown and set in the middle.
