Preheat your oven to 350°F (180°C) and line a 9-inch (22 cm) cake pan with parchment paper.
In a large bowl, beat the eggs and granulated sugar until light, pale and fluffy.
Sift in the flour, baking powder, and a pinch of salt. Gently fold into the egg mixture.
Melt the butter, then mix it with the freshly squeezed orange juice and grated orange zest.
Gently fold the butter-orange mixture into the sponge cake batter until evenly combined.
Pour the batter into the cake pan and bake for 30-35 minutes, or until golden brown and a toothpick inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes, then invert it onto a wire rack and let it cool completely.
Whip the heavy cream until stiff peaks form. Decorate the cake with whipped cream and dust with powdered sugar before serving.
