This is an easy shortcake recipe that can be made using an egg pan without an oven or cake pan. Mix eggs and granulated sugar with a hand mixer, then add cake flour, milk, and melted butter to make the batter. Steam-bake the batter in an egg pan, let it cool slightly, then cut it in half. Spread strawberry jam on one half, and whipped cream and strawberries on the other half, then decorate the whole thing with more whipped cream. Finally, garnish with strawberries and sprinkle with non-melting powdered sugar to complete a cute shortcake.
