Preheat oven to 400°F. Lightly coat twelve 2 1/2-inch muffin cups with nonstick cooking spray. In a small bowl stir together oats, brown sugar, and melted butter.

In a medium bowl stir together next eight ingredients (through salt). Make a well in center of our mixture. In a small bowl combine remaining ingredients. Add egg mixture all at once to our mixture. Stir just until moistened (batter should be slightly lumpy).

Spoon batter into prepared muffin cups, filling each about two-thirds full. Sprinkle oat mixture over batter. Bake 20 minutes or until golden. Cool in muffin cups on a wire rack 5 minutes. Remove from muffin cups. Serve warm.
