Lightly coat a baking sheet with cooking spray; set aside.
In a small saucepan combine water and butter. Bring to boiling. Add flour all at once, stirring vigorously. Cook and stir until mixture forms a ball. Remove from heat. Cool for 10 minutes. Add eggs, 1 at a time, beating well with a wooden spoon after each addition. Drop mixture in 8 mounds, 3 inches apart, on the prepared baking sheet.
Bake in a 400 degree F oven about 30 minutes or until golden. Transfer cream puffs to a wire rack; cool. Cut tops from cream puffs; remove soft dough from inside. Cool completely on a wire rack.
Meanwhile, for filling, prepare pudding mix according to package directions using the fat-free milk. Stir in peppermint extract. Cover surface with plastic wrap. Chill.
To serve, spoon about 1/4 cup of the filling into the bottom half of each cream puff. Replace tops. Sprinkle with sifted powdered sugar. If desired, garnish with fresh strawberries. Makes 8 servings.
