Flatten toasts with a rolling pin and thinly spread Nutella on top. Mash raspberries. Add mashed raspberries to toasts.
Mix eggs and buttermilk. Roll up toasts, then roll them in the egg-buttermilk mixture.
Combine sugar and cinnamon. Fry toasts on all sides in butter until golden, briefly pat dry on paper towels, then quickly roll in sugar-cinnamon-mixture.
Serve with berries, honey and/or yogurt. For a better look, you can also halve the rolls. Want to publish your own recipe? Send it to us at firstname.lastname@example.org
