Growing up in suburban New Jersey in the late 80's/early 90's, a kid's coolness in school could easily be determined by what treat they brought in for their class party on their birthday.
Water, vegetable oil and egg whites called for on cake mix box
24 flat-bottom ice cream cones
1. Heat oven to 350°F (325°F for dark or nonstick pans). Place paper baking cup in each of 24 regular-size muffin cups.
2. Make cake batter as directed on box. Fill each cup 2/3 full of batter (1 heaping tablespoon each). Place ice cream cone upside down on batter in each cup.
3. Bake 15 to 20 minutes or until toothpick inserted in cake comes out clean (cones may tilt on batter). Cool completely, about 30 minutes. Remove paper baking cups. Generously frost cake with frosting, and decorate as desired. Store loosely covered.
High Altitude (3500-6500 ft): Follow High Altitude directions on cake mix box. Fill cones about 1/2 full to make 36 to 40 cones. Bake 20 to 25 minutes.
