Preheat oven to 350 F. Line baking sheets with parchment paper or a non-stick baking mat. In a large bowl, beat together butter and sugar until light and fluffy. Beat in egg yolks, vanilla extract and salt. Gradually stir in flour. Form dough into 20 1-inch diameter balls. Dip in lightly beaten egg whites, then roll in nuts. Place 1 inch apart on prepared cookie sheets. Press down center of each with thumb to make a thumbprint. Place a cherry half in each indentation. Bake for 16 to 18 minutes, or until golden brown. Cool on baking sheet for 5 minutes, then remove to a wire rack to cool completely.
Preheat oven to 375 F. Roll pastry thin and cut into 12 4-inch circles. Fit each round into muffin cup and press in gently. Beat eggs until they are light; add sugar and mix well. Add butter, salt, and vanilla; mix well. Combine walnuts and raisins and fill each cup 1/2 full. Add egg mixture to fill each cup three-quarters. Bake filled cups 20-25 minutes.
Preheat oven to 350F. Grease a 9×13″ baking pan and set aside. In the microwave, melt the butter. In a medium bowl, combine flour, baking powder and salt; set aside. In a large bowl using an electric mixer, beat butter and brown sugar. Slowly beat in the eggs and vanilla, mixing until batter is smooth. On low speed, gradually mix in the flour mixture. Batter will be very stiff. Stir in the chocolate chips and nuts. Spread the batter in the baking pan, smoothing it into the corners. Bake 25 minutes or until the blondies begin pulling away from the sides of the pan. Let cool to room temperature in the pan on a wire rack, then cut into bars.
