I am currently reading my way through a long list of science fiction and fantasy titles. (http://www.npr.org/2011/08/07/138938145/science-fiction-and-fantasy-finalists if you are interested in the list).
Cinnamon Swirl Banana Bread
Preheat the oven to 350⁰F.
Combine crumble ingredients and set aside.
Cream butter and sugars with an electric mixer for 2-3 minutes until fluffy. Add eggs one at a time. Add vanilla and mix in bananas one at a time, until well mixed. Combine dry ingredients and add them alternately with buttermilk, ending with dry ingredients.
Spray a loaf pan with cooking spray. Pour half of the batter into it and spread it out. Sprinkle with ¾ of the crumble. Pour in remaining batter, sprinkle with remaining crumble and press into the loaf. Bake for 50-55 minutes until a toothpick comes out clean.
I used Robin Hood’s blend of gluten free flour. I also find that the amount of crumble is a bit much & try to scale it back a bit. The bananas blend in better if you use thawed bananas (I’m always pitching over-ripe bananas into the freezer).
