Preheat oven to 350°F. Line a 10x15 jelly roll pan with foil and spray with cooking spray.

Whisk together flour, baking soda, salt, cinnamon, and allspice. Set aside.

Beat sugar, butter, and molasses until well combined. Add egg and mix thoroughly.

Gradually add dry ingredients to the wet mixture until a stiff dough forms.

Press dough evenly into the prepared pan. Bake for 15 minutes until golden and set.

Cool for 5 minutes. Remove from pan using foil overhang, place on a surface, and cut into sticks.

Melt white chocolate chips with Crisco or oil in 30-second intervals, stirring until smooth. Drizzle over the sticks.

Press Twix bars into the dough before cutting into sticks. Decorate with sprinkles if desired.

Store in an airtight container for up to 4 days or freeze for longer storage.
