Pre-heat oven to 350 degrees
Mix flour, sugar, cocoa, food color, baking powder, & salt in the mixer bowl & turn it on the slowest setting. (stir)
Combine eggs, & vanilla in small bowl & beat lightly with a fork.
Add the egg mixture to the flour mixture & mix well until combined. It will be sticky but firm.
Fold in the white chocolate chips.
Divide the dough in half for 2 large loaves - I did 3 medium-sized instead. (You should end up with 2 rectangles measuring approximately 4-5 inches on the short end & 7-8 inches on the long end.)
On a lightly floured surface, form each log & place on a parchment-lined baking sheet.
Bake for about 30 minutes or until tops are set.
Remove from the oven & reduce oven temperature to 300 degrees.
Allow logs to cool & then slice about ½ - 1 inch wide.
Lay slices on their side on the baking sheet & bake at 300 for 10 minutes.
Remove- flip the slices over & bake an additional 8-10 minutes.
Cool on a wire rack before decorating or placing them in an airtight container for storage.
