Ingredients :

• Bananas — Take the ugliest ones you can find — half-black skin is no problem at all. The riper they are, the sweeter and more fragrant your batter will be. Three medium bananas are the right proportion for this pan size.
• Applesauce — Only two tablespoons, but they make a real difference in the moistness. Get it plain, unsweetened. The brand doesn’t matter at all here.
• White whole wheat flour — It’s a bit more rustic than classic white flour, but much lighter than regular whole wheat. If you can’t find it, T65 flour works great. For a gluten-free version, Bob’s Red Mill AP blend does the trick.
• Blueberries — Fresh or frozen. If using frozen, definitely do not thaw them first — they will dye the whole batter purple. Fold them in directly from the freezer, just before baking.
