1/2 cup butter at room temperature
1/2 cup packed brown sugar
2/3 cup maple syrup
2 eggs
1 tsp vanilla
2 3/4 cup all purpose flour
1 tsp baking powder
1/2 tsp baking soda
1/4 tsp salt
1 cup walnuts, toasted and coarsest chopped
Maple Glaze
1/4 cup icing sugar
1 1/2 tbsp maple syrup
In large bowl, using electric mixer, beat butter with brown sugar until fluffy. Beat in maple syrup and vanilla. Beat in eggs 1 at a time. Beat in vanilla. In separate bowl whisk together flour, baking powder, baking soda, and salt. Stir into butter mixture in two additions to form slightly sticky dough. Stir in walnuts.
Divide dough in half. On lightly floured surface form each into 12 inch long logs. Place 3 inches apart on parchment paper lined baking sheet. Press to flatten to 2 1/2 inches wide. Bake in 325 degree oven for 30 minutes or until firm.
Transfer logs to a cutting board; cut on diagonal into 1/2 inch thick slices. Stand slices up 1 inch apart on baking sheet. Bake in 300 F oven for 30 minutes or until almost dry. Transfer to a wire rack; let cool completely.
Maple Glaze
In small bowl, whisk icing sugar with maple syrup. With cooled biscotti sitting side by side, drizzle glaze over tops. Let stand until set about 15 minutes.
