Preheat the oven to 350 degrees. Line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, herbes de Provence, baking powder, and salt.
In a stand mixer, beat the butter and goat cheese together until smooth.
Beat in the sugar and eggs.
Add the flour mixture in batches and beat until just combined.
Transfer the dough to the prepared baking sheet.
With dampened hands, form the dough into a 13"L x 3 1/2" wide loaf.
Bake for 30 minutes.
Cool on the baking sheet for 20-30 minutes, or cool enough to handle.
Transfer the loaf to a cutting board. Using a serrated knife, cut the log on the diagonal into 1/2 inch thick slices. Place the biscotti, cut side down, on the baking sheet. Bake until pale golden, about 15 minutes. Transfer the biscotti to a wire rack and cool completely.
