Baking in Glass Baking Dish
If a recipe calls for a metal pan and you substitute a glass baking dish, always reduce the oven temperature by 25ºF. This is necessary since the glass dish conducts and retains heat better than the metal pan.
How to Bake as Individual Brownies
Prepare brownie and cookie batters as directed. Spoon brownie batter into 24 muffin pan cups sprayed with cooking spray. Top with cookie dough, adding about 2 Tbsp. to batter in each cup. Bake in 350ºF oven 24 to 26 min. or until toothpick inserted in centers comes out clean. (Do not overbake.) Makes 24 servings.
