1. Heat oven to 350 degrees F. Lightly spray an 8-inch square metal baking pan with cooking spray. 2. Pour contents of No Pudge! Fudge Brownie Mix into a medium bowl. Using a spoon, stir in 2/3 cup of non-fat vanilla yogurt. (You can substitute with plain yogurt. Just add one teaspoon of vanilla extract). The batter will be very thick. Stir well until the batter is smooth. Spread into pan. 3. Bake for 30 to 35 minutes. Makes about 12 brownies. Single Serve in a Minute: In a small microwavable container, stir 2 tablespoons of No Pudge! Fudge Brownie Mix for every 1 tablespoon of non-fat vanilla yogurt. Stir until smooth. Microwave on high for about 1 minute. Top with non-fat whipped topping or frozen yogurt for a delicious treat. Helpful Extras: Cutting Tip: When pan is no longer hot, refrigerate until chilled. Run sharp knife or pizza cutter under hot water and cut, rinsing under hot water after each cut. Cake-Like Brownies: Reduce yogurt to 1/2 cup and add 1 egg white. Bake as directed. Lactose Intolerant: Can substitute yogurt with applesauce, non-fat sour cream, silken tofu or soy yogurt. Add 1 teaspoon vanilla extract.
