¼ cup(s)

Vanilla extract

2 tsp(s)

Powdered sugar (confectioner's)

14 tbsp(s), (3/4 c plus 2 Tbsp)

All-purpose flour


Unsweetened cocoa powder

¼ cup(s)

Baking soda

¼ tsp(s)

Table salt


Bittersweet chocolate

1½ oz, (43 g), finely chopped (70% cocoa)

Light butter

2 tbsp(s), cut up


1 large egg(s)

Egg whites

2 egg white(s), large

Heavy whipping cream

¼ cup(s)

Powdered sugar (confectioner's)

1 tbsp(s)

Reduced-fat sour cream

¼ tbsp(s)

Vanilla extract

¼ tsp(s)

Pomegranate seeds

½ cup(s)


  1. Preheat oven to 180°C (350°F). Line an 20-cm (8-inch) square baking pan with parchment paper or nonstick aluminum foil so foil hangs over edges a little bit (or coat pan with cooking spray).
  2. Combine squash and water in a microwavable mixing bowl; cover with vented plastic wrap (or wax paper). Microwave on High until squash is fork-tender, 8 minutes. Mash squash with potato masher or large spoon; stir in 2 tsp vanilla extract and let cool until lukewarm.
  3. Meanwhile, in a medium bowl, sift together 210 ml (14 Tbsp) powdered sugar, flour, cocoa, baking soda and salt.
  4. Combine chocolate and butter in a small microwavable bowl; cover with wax paper and microwave on Medium 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; spread into an even layer. Bake until a toothpick inserted in center comes out with a few moist crumbs clinging, 25 minutes. Cool completely in pan on wire rack.
  7. While cake cools, in a small bowl, using an electric mixer, beat cream until thickened. Add powdered sugar; beat until stiff peaks form. Fold in sour cream and vanilla just until blended.
  8. Remove cake from pan; remove parchment or foil. Cut into 12 pieces and serve topped with cream and pomegranate arils.
  9. Serving size: 1 piece cake, 15 ml (1 Tbsp) vanilla cream and 15 ml (1 Tbsp) pomegranate arils
