- Beat margarine and sugar together in a large bowl until smooth. Combine cornmeal, flour, baking powder, and salt in another bowl. Stir eggs and milk in a third bowl. Pour 1/3 milk mixture and 1/3 flour mixture alternately into margarine mixture; whisk until just mixed. Repeat with remaining ingredients and stir in jalapeno peppers. Spread mixture evenly into prepared baking pan.
