You gotta try this recipe for my favorite Mini Lemon Pudding Cake. It all comes together in one batter and once the mini puddings bake, the batter starts to separate into two luscious layers.
Preheat the oven to 325F.
Grease 8 ramekins (6 ounces each) with the unsalted butter for individual servings or one 2-quart baking dish; set aside.
In a large bowl, whisk together the egg yolks, ½ cup of sugar, butter, lemon zest, lemon juice, and milk.
In a separate bowl, mix together the flour and baking powder.
Add the flour mixture to the egg yolk mixture and mix well.
In a clean bowl and with clean beaters, whip the egg whites by using room temperature egg whites and whipping on high speed with a pinch of salt until soft peaks form.
Gradually add the remaining sugar while continuing to beat the egg whites until stiff peaks form.
In 3 additions, gently fold in the egg white mixture into the batter using a spatula; be careful not to over fold or deflate the batter.
Divide the batter among the ramekins and place on a towel-lined deep roasting pan.
Pour hot water into the roasting pan to come halfway up the sides of the ramekins.
Bake until the cakes are puffed and slightly golden, about 30 minutes.
When done, remove the ramekins carefully using kitchen tongs and a small kitchen towel.
Allow them to cool to room temperature or chill them if you prefer a cold cake.
Just before serving, dust the tops with icing sugar.
