I came to this sweet little recipe here, and she found it in Feeding the Whole Family

Mary’s Buttermilk Chocolate Cake

1 1/4 cups whole wheat pastry flour

1/8 cup cocoa powder

1/4 tsp sea salt

1/2 tsp baking powder

1/2 tsp baking soda

1/2 buttermilk

1/4 cup butter, melted

1/2 cup maple syrup

2 tsp vanilla

Preheat oven to 375 F. Lightly oil an 8″ square baking pan. Whisk dry ingredients together in a bowl. In a separate bowl, combine remaining ingredients, then stir into flour mixture. Pour batter into pan. If you’re like us, sprinkle the top with dark chocolate chips. Bake 25-30 minutes or until a tooothpick inserted into the middle of the cake comes out clean. Serve with sliced strawberries!
