This is from Williams-Sonoma - http://www.williams-sonoma.com/recipe/pizzelle.html
It is the recipe a good friend uses for hers, and we like it a lot.
Ingredients:
3 eggs
3/4 cup sugar
8 Tbs. (1 stick) unsalted butter, melted, plus
more for brushing
2 tsp. vanilla extract
1 tsp. finely grated lemon zest
1 3/4 cups all-purpose flour
2 tsp. baking powder
Directions:
In a mixing bowl, whisk together the eggs and sugar until light yellow and thick ribbons fall from the whisk, 2 to 3 minutes. Add the 8 Tbs. melted butter, the vanilla and lemon zest and whisk until blended.
Over a sheet of waxed paper, sift together the flour and baking powder. Fold the flour mixture into the egg mixture in two additions, folding each addition just until blended.
Heat a pizzelle maker according to the manufacturer's instructions. Brush lightly with butter and spoon about 1 Tbs. of the batter onto the pizzelle maker. If any batter oozes out, cut it off immediately. Cook according to the manufacturer's instructions until golden brown. Transfer the pizzelle to a wire rack and let cool. Repeat with the remaining batter.
Makes about 25 pizzelle.
