“Killer brownies” is the nickname for these intensely rich, fudgy treats. Each bite is full of deep chocolate flavor and has an incredible texture. These are sure to delight your valentine.

Directions:
1. Center a rack in the oven and preheat to 350°F. Spray the inside of an 8-cavity 2" heart-shaped silicone pan with non-stick spray and place on a baking sheet.
2. Melt the chopped chocolate and butter in a microwave-safe bowl on low power for 30-second bursts. Stir after each burst.
3. Use an electric mixer to beat the egg and yolk in a bowl until frothy. Add the sugars and whip until very thick and pale colored, about 5 minutes. Add the melted chocolate mixture and blend completely.
4. Sift together the flour and cocoa powder and add the salt. Add to the mixture in 3 stages, blending well after each addition. Stir in the walnuts.
5. Divide batter evenly among cavities of the pan. Bake 35 minutes, until a tester comes out slightly moist. Remove from the oven and cool the pan on a rack. Turn the pan upside-down and gently peel away from the brownies, then turn brownies top-side up.
6. Store in a single layer in a tightly sealed container or covered with foil at room temperature up to 5 days.

Makes 8, 2" heart-shaped brownies.
