Simple yet festive, these adorable COOKIES 'N' CREME Tree Bars are perfect for the holidays. Enjoy!
Preheat oven to 350°F (180°C). Grease 9-inch (23-cm) square baking pan or line with parchment paper, extending parchment above pan edges.
Beat butter, sugar, brown sugar, egg and vanilla in large bowl until well combined. In a separate bowl, stir together flour, baking soda and salt; add to butter mixture. Stir in baking pieces and spread in prepared pan.
Bake 25 to 30 minutes or until lightly browned on the edges. Cool for 10 minutes. Using a tree-shaped cookie cutter (or any other holiday themed cookie cutter of your choice), cut out as many shapes as you can. Place cut-out bars on a baking sheet and let cool completely.
While bars cool, place ¼ cup (50 mL) reserved white chocolate chips and milk in a microwave-safe bowl. Microwave on HIGH for 30 seconds. Stir until melted. Using a fork, drizzle bars with melted baking chips and decorate with green sprinkles.
