Preheat oven to 400F, prepare pans. In a small saucepan (or e)
heat chocolate chips & butter until melted, stirring constantly; remove
from heat & reserve. In a bowl stir together flour, sugar, b/pdr & salt. In
another bowl stir together milk, p/butter, oil, egg & vanilla. Add dry mix
to wet mix until just combined. Spoon half of batter into pans. Divide

until lightly browned. Makes 9 muffins. Variation: A ripe banana cut into
1/2″ thick slices & dipped in orange juice may be used instead of the fudge
filling.
