Make this for our Cocoa Buttermilk Cake.
Preheat oven to 375 degrees. Put egg whites and sugar into the bowl of an electric mixer fitted with the paddle attachment; mix on medium speed until combined. Mix in flour and salt. Add butter, cream, and vanilla; mix until just combined.
Spoon 4 teaspoons batter onto a baking sheet lined with a nonstick baking mat. Thinly spread into a 5-by-5 1/2-inch rectangle. Repeat. Bake until pale golden around edges, about 6 minutes.
Transfer sheet to a wire rack. Immediately loosen cookies with a spatula; flip. Starting at 1 short side, quickly roll cookie to the halfway point using the handle of a small wooden spoon. Repeat on opposite side. Repeat with remaining batter. Transfer to a wire rack; let cool.
Cut candy belts in half lengthwise, about 3/8 inch wide. Wrap 1 candy strip around each scroll, and knot.
