Preparation

• Preheat an oven to 350ºF. Grease and flour a loaf pan 8 1/2" x 4 1/2" x 2 3/4" high also called 1lb loaf pan
  
  In a small bowl, stir and toss together the flour, baking powder, baking soda and salt. Set aside.
  
  In a bowl, using a whisk, beat the butter until smooth, then slowly add the maple syrup, whisking constantly. Whisk in the sour cream and egg. Stir in the pecans. Add the flour mixture and stir until just blended.
  
  Spoon the batter into the prepared pan and bake until a toothpick inserted into the center of the loaf comes out clean, 50 to 60 minutes. Transfer the pan to a wire rack and let cool for 15 minutes, then turn the loaf out onto the rack and let cool completely.
