Mix-in ideas: Add ½ to ¾ cup dark chocolate chips, chopped walnuts, or chopped pecans into the batter before baking.
Streusel topping variation: Combine ¼ cup rolled oats, 2 tablespoons flour, 1 teaspoon pumpkin pie spice, ¼ cup turbinado sugar and ¼ cup salted butter cut into pieces. Cut in the butter using a pastry cutter or fork until a crumbly streusel forms. Sprinkle on top before baking.
Glaze topping variation: Make 1 recipe of this Maple Glaze and drizzle it over the muffins with a fork. Or, use the Salted Caramel Glaze from this Brown Butter Banana Bread recipe.
