Preheat oven to 350° F. Line baking sheets with parchment paper.
In a mixer fitted with a paddle attachment, mix almond paste, both sugars, flour and egg whites until well-blended and smooth. Pipe one-inch rounds onto a paper-lined pan using a plain piping tip fitted in a pastry bag. With damp fingertips, press down any peaks. Bake until lightly golden, about 10 to 12 minutes. Allow to cool on pans before removing from paper.Makes 1 dozen Source:
