About this recipe:Here's an astounding achievement: chocolate-nut biscuits with less than one gram of fat each! The secret is meringue. These biscuits contain no butter or margarine and no egg yolks, yet they're tender and rich tasting.
Preheat the oven to 150°C. Line 2 baking trays with baking paper. Toast the walnuts in a small saucepan, stirring frequently, until crisp and fragrant, about 7 minutes. When cool enough to handle, coarsely chop.
Sift together 1/2 cup icing sugar, cocoa powder and cinnamon.
Place the egg whites in a large bowl and beat with an electric mixer until stiff peaks form. Gently fold in the cocoa mixture with a spatula. Gently fold in the nuts.
Drop generous teaspoonfuls of the mixture onto the baking trays, spacing them 2 cm apart. Bake until set, about 20 minutes. Remove and cool on a wire rack. Dust with the remaining icing sugar just before serving.
