Banana Blueberry Bread

From Anne's Food

150 g wholewheat flour (I use spelt) 150 g all-purpose flour 75 g sugar 75 g brown sugar 1/2 tsp salt 1 tsp baking soda 4 bananas (about 450 g, peeled weight), mashed 100 ml canola oil 100 ml buttermilk (or Swedish filmjolk) 2 eggs 1 vanilla bean 200 g blueberries, fresh Start by mixing both flours and both sugars with salt and baking soda in a bowl. Mash the bananas and mix with oil, buttermilk and eggs. Score the vanilla bean and scrape out the "caviar" into the wet ingredients and mix well. Add all the wet stuff to the dry ingredients and stir together. Butter and flour two small bread tins (mine are 8 inches/20 cm) and divide the batter between them. Push the blueberries into the batter, half in each tin. Bake at 175°C for about 45 minutes. You can certainly use a larger tin or make muffins, but you do need to adjust the baking time.
