I got this from my all-time favorite cookbook, Fannie Farmer. It's Northern-style cornbread -- sweet and yellow.
¾ C yellow cornmeal
1 C flour
1/3 C sugar
1 T baking powder
½ tsp salt
1 C milk
1 egg, well beaten
2 T oil or melted butter
Preheat oven to 425°. Grease an 8" square pan. Combine the dry ingredients in a large bowl, then add the rest. Mix well. Pour into pan and bake for about 20 minutes. Cool and cut into squares.
Variations: Add cheese, corn, green chilis, cubed ham, etc.
