1-teaspoon baking soda
1/2 teaspoon salt. (If you want this can be left out if making peanut butter cake)
3/4 cup sugar.
1/4 cup peanut butter more or less to taste
1/2 cup skim milk
1/3 cup water
1 teaspoon vanilla extract
3 tablespoons vegetable oil or apple sauce
Mix dry ingredients together then add wet ones and mix just enough to moisten. Don't worry if batter feels stiff sometimes it dose and other times it doesn't.
Spoon into an 8-inch square pan greased and floured
Bake for 30 minutes at 350°. When done sprinkle powered sugar over it or frosting.
I double everything and bake in a bunt tin for 45 minutes or till toothpick comes out clean...
If you change peanut butter for 1/4 cup unsweetened cocoa you can make a chocolate cake
