Ingredients

  • 3 1/2 - 4 cups flour
  • 3/4 cup sugar
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1/2 cup sweet butter, cut up
  • 1 ripe banana
  • 3 eggs, separated
  • 1/2 pint low-fat vanilla yogurt
  • jelly or preserves, for filling

Method

  • You really need to do this with clean bare hands (or gloves, if you prefer)--mash the butter and banana into all the dry ingredients in a large bowl until the mixture is crumblike.
  • Smush in the egg yolks and yogurt. If it's very sticky, add more flour a bit at a time until it is a good, doughy texture.
  • Divide it into four parts and stick them in the freezer for 20-30 minutes.
  • When you take out the first part, transfer the others to the fridge.
  • Roll the first part flat, but not too thin.
  • Flour the rim of a drinking glass and use it to punch out circles of dough, placing them on a greased cookie sheet.
  • Put a spoonful of filling in the center of each circle and squish up the edges in the shape of a triangle, leaving some of the filling exposed in the middle.
  • Brush the dough with the egg whites and bake at 350° for 10-15 minutes or until golden brown.
  • Repeat this process with the other three sections of dough.
  • Remove from cookie sheets, let cool on a wire rack and enjoy.
