Fudgy chocolate cake

Instructions

1. Preheat oven to 350°F. Line 8-inch square baking pan with nonstick aluminum foil (or coat with cooking spray if you prefer).
2. Combine squash and water in a microwavable bowl; cover with vented plastic wrap or wax paper. Microwave on High until squash is fork-tender, 8 minutes. Mash squash with a potato masher or large spoon; stir in vanilla and cool until lukewarm (place in refrigerator to cool faster).
3. Meanwhile, sift together powdered sugar, flour, cocoa, baking soda and table salt into a medium bowl.
4. Combine bittersweet chocolate and butter in a small microwavable bowl; cover with wax paper. Microwave on Medium (50% power) until chocolate softens and butter begins to melt, 15 seconds; stir until smooth.
5. Stir melted chocolate into squash until blended; beat in egg and egg whites by hand. Gently fold in flour mixture just until blended.
6. Pour batter into prepared pan and spread into an even layer; sprinkle top with cereal, chocolate chips and sea salt. Bake until a toothpick inserted in center comes out with just a few moist crumbs clinging to it, 25 minutes; cool completely on rack. Remove foil from pan; cut into 12 equal pieces.
7. Serving size: 1 piece
