01 - Preheat oven to 350°F. Line a baking sheet with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt until well blended.
03 - In a large bowl, beat butter and sugar together until light and fluffy, about 2-3 minutes.
04 - Add eggs one at a time, beating thoroughly after each addition. Mix in vanilla and almond extract.
05 - Gradually incorporate dry ingredients into wet mixture, mixing until just combined. Do not overmix.
06 - Divide dough in half. On a lightly floured surface, shape each half into a 12-inch by 2-inch log.
07 - Place logs on prepared baking sheet, spacing apart. Flatten slightly and sprinkle with coarse sugar if desired. Bake for 25-28 minutes until lightly golden.
08 - Remove from oven and let cool for 10 minutes. Reduce oven temperature to 300°F. Slice logs diagonally into 3/4-inch pieces using a sharp serrated knife.
09 - Arrange slices cut side down on baking sheet. Bake for 12-15 minutes, flip, then bake an additional 10-12 minutes until crisp and golden.
10 - Cool completely on wire rack. Drizzle with melted white chocolate if desired and allow to set before serving.
