Grease a deep non-metal baking dish. (I use an 8" x 8" baking dish)
Preheat oven to 375 degrees.
Soften 2 tablespoons of butter.
Mix 1 cup flour, 1 teaspoon baking powder, and ½ teaspoon salt. Set aside.
With whisk or electric mixer, vigorously beat 2 eggs with 1 cup sugar.
Add any flavors, such as splash of vanilla, lemon zest, almond extract, or cinnamon.
Add 2 tablespoons milk and the softened butter, mix well.
Sprinkle half of flour mixture over wet ingredients. Mix lightly with spoon/spatula. Combine the rest, being careful not to over-mix.
Pour batter into prepared dish. Cover with fruit.
Bake for almost one hour. The center may seem a little raw, but it will solidify once it has cooled down.
