Banana and Blueberry Bread

I have adapted a recipe out of the Woman's Day ABC of Kids Cooking for this- thanks for the inspiration! First melt 125 g of unsalted butter at 70g for 3 mins speed 3. Add to that 3 mashed bananas, 3 eggs and 1 tsp vanilla extract and mix at speed 4 for 30 seconds (note if you are short on a banana you can successfully substitute 1/2 cup of other soft/stewed fruit). In a separate bowl sift together 1 cup plain flour, 1 cup wholemeal self raising flour and 2 tsp baking powder. Add 1 cup brown sugar (I have also substituted 1/2 cup rapadura sugar for half of the brown sugar) and stir until combined, breaking up any brown sugar lumps in need. Stir in 3/4 cup frozen blueberries then using a fork mix in the butter/egg mix until combined. Spoon into a lightly greased or non stick loaf tin and bake at 175 degrees fan forced oven for 55-60 minutes or until a skewer stabbed through emerges clean. This should freeze well for lunch boxes and is very nice served warm with butter!
