Step 1

Preheat the oven to 375 degrees F (190 degrees C). Grease a 9x5-inch loaf pan.

Step 2

Sift flour, sweetener, baking powder, cinnamon, baking soda, and salt in a bowl; set aside.

Step 3

Mix avocado, buttermilk, egg, and vanilla together in a separate bowl. Add dry ingredients and mix until just combined. Stir in pecans. Pour batter into the prepared pan.

Step 4

Bake in the preheated oven until a toothpick inserted in center comes out clean, 60 to 75 minutes. Cool in the pan for 10 minutes. Invert onto a wire rack and cool completely before slicing.
