Honeyville because it's more finely ground and works best
1 teaspoon baking soda
1 tablespoon baking powder
1/2 cup xylitol or a combination of 1/4 cup xylitol and 1/4 cup erythritol** (see notes, taste a bit of the dough to check sweetness and add more to taste)
Variations: Add these things, if using, as a last step before turning the batter out into the loaf pan.
Add 1 1/4 cup toasted, coarsely chopped walnuts
1/2 cup semi-sweet chocolate chips (contain sugar so this will no longer be sugar-free)
Instructions
Adjust oven rack to lower middle position and preheat oven to 350°. Grease a regular 9" x 5" x 3" loaf pan with butter or coconut oil.
In a large bowl, mash enough bananas to equal 1 1/2 cups (pour into a measuring cup to check and then add back into the bowl). You should need about 3 regular bananas or 6 apple bananas.
Add butter, eggs, yogurt, and vanilla to bananas in bowl and stir to combine.
Add almond flour, baking soda, baking powder, and xylitol/erythritol to bowl. With a large spatula, stir to combine well. No need to worry about over mixing since there is no gluten in the almond meal. Add walnuts and/or chocolate chips if using. Stir to combine.
Pour batter into prepared pan. Slice remaining banana (1 regular or 2 apple bananas) into 1/4" thick rounds and lay, overlapping like shingles, on top of batter, creating 2 rows along the sides. Leave the middle open so that the bread will rise properly. This decorative step is optional.
Bake for approximately 55 minutes, or until a toothpick comes out clean when inserted into the center. Let cool in pan for 10 minutes.
Run a sharp knife around the edges of the pan and gently invert bread to remove.
Notes:
* Apple bananas are a variety of banana commonly found in Hawaii. They are smaller and sweeter than a regular banana. Their name comes from the supposed idea that they have a slight apple flavor. It makes no sense to me.
** The jury is still out on which sweetener is better for you. So I'm using some of each to hedge my bets.
