Gluten-Free Banana Bread

My husband, who is not Gluten-Free (yet), devours this bread. He absolutely loves it!!
TO UP THE CALORIES: use organic olive oil in place of the butter and add about 1/8 teaspoon of salt
2 cups Gluten-Free flour
1 teaspoon baking soda
1/2 teaspoon xanthan gum
1/2 cup butter
less than 1 cup raw sugar/honey
2 eggs
3 ripe bananas (peeled and mashed)
1/2 cup chocolate chips (optional)

Combine flour, baking soda and xanthan gum. In small bowl, cream butter until white. Add the sugar and beat until fluffy (a couple minutes.) Add eggs. Stir in bananas. Stir in dry ingredients just until blended. Fold in chocolate chips. Place batter in greased and lightly floured (rice of course) loaf pan. Bake 1 hour at 350 degrees
