Recipe type: Brunch
Cuisine: American
Serves: 4-6
  • ¾ cup sugar
  • ½ cup butter, softened
  • 1 egg, slightly beaten
  • 1 cup fresh buttermilk
  • 2 cups flour
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • Sugar Topping:
  • ½ cup sugar
  • ¾ teaspoon cinnamon
  1. Preheat oven to 375 degrees.
  2. In a medium mixing bowl, cream together the butter and sugar until light and fluffy.
  3. Break an egg and beat slightly. Beat into the butter and sugar mixture.
  4. Slowly add in 1 cup of fresh buttermilk and mix well with a whisk. Set aside.
  5. In a separate medium mixing bowl, measure the flour, baking powder, baking soda, and salt into a fine sieve and sift all into the mixing bowl.
  6. Stir the dry ingredients into the wet and mix until well combined. The batter will be thick.
  7. Butter an 8" x 8" square baking dish (you can also use a 7" x 11" baking dish) well and spread the batter evenly. In a small dish, mix the sugar and cinnamon together. Sprinkle liberally on top of the batter.
  8. Bake in a 375 degree oven for 30 minutes or until a toothpick inserted in the center come out clean.
Serve warm or make the cake ahead the day before. The flavors will mellow and taste even better the next day.

You can also substitute powdered buttermilk if you cannot purchase fresh buttermilk. Just follow the instructions on the can of powdered buttermilk so you add the correct amount of power and liquid.
