  • Optional: ½ cup peanuts or raisins, chopped

Yield: 8 Bars

Preheat the oven to 375°

Combine the dry ingredients in a large bowl, adding any optional ingredients. Mix together the liquid ingredients in another bowl. Make a well in the dry ingredients and add the liquid ingredients, using a rubber spatula to combine. The batter should be thick.

Press the mixture into a 9×9-inch square coated cake pan. Bake the bars for 14 to 15 minutes, or until the edges are browned. Let cool in the pan and cut into 8 servings.
