Ingredients
1 box (1 lb 6.25 oz) Betty Crocker™ Supreme original brownie mix
Water, vegetable oil and eggs called for on brownie mix box

Miniature candy canes (2 inch), unwrapped
Directions
• 1 Heat oven to 350°F (325°F for dark or non-stick pan). Line 9-inch square pan with foil so foil extends about 2 inches over sides of pan. Grease bottom only of foil with shortening or cooking spray.
• 2 Make brownie mix as directed on box for 9-inch square pan. Cool completely, about 1 1/2 hours. Remove from pan by lifting foil; peel foil away. To cut brownie into triangles, cut into 3 rows. Cut each row into 5 triangles (See diagram below in Expert Tips). Save smaller pieces for snacking.
• 3 Stir food color into frosting. Spoon frosting into small resealable food-storage plastic bag; partially seal bag. Cut off tiny bottom corner of bag. Squeeze bag to pipe frosting over brownies. Sprinkle with decors.
• 4 Break off curved end of candy cane; insert straight piece into bottoms of triangles to make tree trunks.
