The slight acidity of buttermilk tenderizes and moistens baked goods while allowing you to cut way back on butter or oils. Here, it also lends a slight tanginess to the winning combination of bananas and blueberries.
Make Ahead Tip: Wrap and store at room temperature for up to 2 days or freeze for up to 1 month. To defrost and heat frozen muffins, remove plastic wrap, wrap in a paper towel and microwave on High for 30-45 seconds.
Equipment: Muffin tin with 12 (1/2-cup) cups.
Note: Whole-wheat pastry flour, lower in protein than regular whole-wheat flour, has less gluten-forming potential, making it a better choice for tender baked goods. You can find it in the natural-foods section of large supermarkets and natural-foods stores. Store in the freezer.
Storage smarts: For long-term freezer storage, wrap your food in a layer of plastic wrap followed by a layer of foil. The plastic will help prevent freezer burn while the foil will help keep off-odors from seeping into the food.
