Seeded Graham Biscotti

Preheat oven to 350 degrees. Whisk together flours, baking powder, baking soda, salt, allspice, and hemp and fennel seeds in a bowl. In another bowl, beat brown sugar, eggs, vanilla seeds and extract, and zest on medium speed until pale and thickened, about 4 minutes. Beat in flour mixture. Stir in almonds.

Shape dough into a 3-by-12-inch log. Combine sanding sugar and sesame seeds on a rimmed baking sheet; roll log in mixture to completely coat. Transfer to a parchment-lined baking sheet; bake until golden, about 30 minutes. Let cool completely on sheet on a wire rack.

Transfer log to a cutting board. Slice with a serrated knife into 1/3-inch-thick slices. Return slices to baking sheet. Bake until golden brown, rotating sheet once, about 10 minutes. Let cool completely on sheet on wire rack before serving. (Biscotti can be kept in an airtight container at room temperature up to 1 week.)
