Preheat oven to 375º F. Spray a 9 inch round or square cake pan with cooking spray.
In a large mixing bowl, combine flour, Truvia, salt, baking powder and baking soda.
In a smaller bowl, mix the buttermilk, egg and melted coconut oil with a whisk. Pour into the flour mixture and stir until blended. Batter will be thick and crumbly.
Scoop batter into pan and mound in the center. Brush top of dough with 1 Tbsp. melted butter and let the bread rest for 5 minutes before putting in the oven.
Bake for 35-40 minutes or until golden brown and a toothpick inserted into the center comes out clean.
Cut bread into wedges and serve warm. Store in an air-tight container
Notes
*If you don't have buttermilk on hand, use 1 1/2 cups milk and add 1 1/2 Tbsp. either vinegar or lemon juice to the milk and let sit for 5 minutes. Use this in place of the buttermilk.
