Big Buch Breakfast Raisin Bran Muffins

This is the legendary refrigerator muffin batter that’s been passed around church cookbooks and family kitchens for decades. The whole batch (enough for three dozen) gets mixed once and stashed in the fridge in a sealed jar, ready to scoop and bake whenever the mood strikes. The batter improves over time, turning thicker and more flavorful as it sits, so day-five muffins might actually beat day-one.

Buttermilk is what makes this work. The acid keeps the leavening reactive even after a week in the fridge, so muffins still rise tall and tender. Pumpkin pie spice carries warm cinnamon-clove-ginger notes through every bake without any extra effort.

Keeps in the fridge for up to six weeks. Bake fresh batches as needed for breakfast, after-school snacks, or quick gifts.

Pro Tips

• Use a quart-sized mason jar or a tightly sealed plastic container. Loose lids invite stale air.
• Don’t stir the chilled batter before scooping. Disturbing it deflates the leavening.
• The hot 425 degrees F (220 degrees C) oven is what makes muffin tops dome high and crackle.
• Bake muffins straight from the cold batter without warming. Cold batter holds its shape in the tin.

Variations

• Stir 1 cup chopped walnuts, pecans, or sunflower seeds into the bowl when scooping for crunch.
• Add fresh blueberries or chopped apple to individual scoops just before baking.
• Substitute molasses for half the brown sugar for a deeper, almost gingerbread flavor.
