Rum-Soaked Raisin Biscotti

Preheat oven to 350 degrees. In a large bowl, whisk together flour, sugar, baking powder, and salt. Using an electric mixer, beat in eggs and vanilla until combined. Combine raisins and rum. Microwave 2 minutes; let cool. Add rum-raisin mixture and orange zest and beat until combined.

Divide dough in half and transfer to a parchment-lined rimmed baking sheet. Form each half into a 2 1/2-inch-wide, 3/4-inch-tall log. Bake until dough is firm but gives slightly when pressed, 20 to 25 minutes, rotating sheet halfway through. Let cool on sheet on a wire rack, 20 minutes.

With a serrated knife, cut logs into 1/4-inch slices on the diagonal and arrange, cut side down, on two parchment-lined rimmed baking sheets. Bake until biscotti are crisp and golden, about 15 minutes, rotating sheets and flipping biscotti halfway through. Let cool on sheets on wire racks.
