Combine flour and sugar in a mixing bowl; make a well in center of mixture.
Combine remaining ingredients except for confectioners' sugar; add to dry ingredients,
stirring just until moistened. Spoon into greased and floured 1 1/2-inch muffin
pans, filling about two-thirds full.
Bake at 400 degrees F for 12 to 14 minutes or until edges are lightly browned.
Remove from pans; sprinkle with confectioners' sugar.
