Whisk the low-fat quark, raisins and eggs into a mixture. Process the oatmeal into a flour with a mixer. Mix the flour well with the egg white powder, spelled flour, powdered sugar, baking powder and vanilla sugar. Then add the flour mix in portions to the low-fat quark mix and whisk. If necessary, add a little sweetener and lemon flavor. When everything is whisked together, add 2 more large shots of mineral water and mix. The dough should be quite tough. Now bake the batter in a waffle iron of your choice. Makes about 11 large waffle hearts.
