Preheat oven to 350 degrees F.

In a large bowl, stir together flour, sugar, baking powder and salt. Cut in the butter using two forks (or your hands) until the mixture resembles crumbs.

Set aside 1 Tbsp of the beaten eggs. Add the rest of the eggs, extract of your choosing, and mix ins to the flour mixture and knead until the dough comes together. 

Turn the dough out into the USA PAN Biscotti pan, pressing the dough down into an even layer. Brush the tops with the remaining beaten egg.

Bake 23-25 minutes. Remove from the oven and cool 10 minutes. Keep the oven on!

Once cooled, turn out onto a cutting board. Using a sharp serrated knife, cut the logs into 1/2-inch thick slices and place cut-side down on a baking sheet. 

Return to the oven and bake for 15 minutes, flipping halfway through. They should be toasted and golden brown. Cool for 15 to 20 minutes.

Melt chocolate of your choosing in microwave in 30 second intervals, stirring between, until smooth. Add melted chocolate to a Ziplock bag and trim the corner. Drizzle the cookies with both chocolates and sprinkle any desired toppings on top.
