Ingredients

1/2 cup butter, softened3/4 cup sugar1 large egg, room temperature1 teaspoon almond extract1/4 teaspoon vanilla extract2 cups all-purpose flour1 teaspoon baking powder1/2 teaspoon salt1 ounce unsweetened chocolate, melted1/3 cup finely chopped pistachios5 drops green food coloring, optional

Preparation

Cream butter and sugar until light and fluffy, 5-7 minutes. Beat in egg and extracts. In another bowl, whisk together flour, baking powder and salt; gradually beat into creamed mixture.

Divide dough in half. Mix melted chocolate into 1 portion; mix pistachios and, if desired, food coloring into remaining portion. Divide each dough into 4 portions.

On a lightly floured surface, roll 1 chocolate portion into an 8x3-in. rectangle. Roll 1 green portion into an 8-in. log; place on chocolate rectangle 1 in. from a long side. Roll chocolate dough around green log; pinch seam to seal. Wrap in waxed paper. Repeat with remaining dough. Refrigerate until firm, about 1 hour.

Preheat oven to 350°. Unwrap and cut dough into 1/4-in. slices. Place 2 in. apart on lightly greased baking sheets. Bake until set, 8-10 minutes. Remove from pans to wire racks to cool.
