Combine preserves and almond extract in a small bowl.
Lightly spoon flours into dry measuring cups; level with a knife. Combine flours, baking powder, baking soda, and salt in a large bowl; make a well in center of mixture.
Combine the brown sugar, egg, and egg white in a medium bowl, and stir well with a whisk. Add the buttermilk, oil, orange rind, and vanilla, and stir well. Add to the flour mixture, stirring just until moist.
Spoon 2 tablespoons batter into each of 12 muffin cups coated with cooking spray. Divide the apricot mixture evenly in the center of each muffin cup (do not spread over the batter), and top with the remaining batter. Sprinkle the batter evenly with 2 teaspoons granulated sugar and almonds.
Bake at 400 for 20 minutes or until the muffins spring back when touched lightly in center. Run a knife or spatula around the outer edge of each muffin cup. Carefully remove each muffin, and place on wire rack.
