2 teaspoons baking powder

Add brown sugar and simmer over moderate heat until sugar is melted and the mixture is sticky, about 4 minutes. Remove from heat. Arrange Starfruit on top of sugar mixture.  Set aside.
Sift together flour, making powder, and salt. Beat butter in a large bowl with an electric mixer until light and fluffy, then gradually add sugar, and eggs, 1 at a time.
