Black and Blueberry and Oat Muffins

5 from 3 votes
Recipes for baked goods often call for the cold ingredients to come to room temperature before mixing. This is especially helpful when using melted butter, coconut oil, or honey which tend to re-harden upon contact with cold ingredients. If this happens, I very gently and slowly heat the batter in the microwave until I can incorporate the ingredients fully–but not cook them.

Ingredients
 

  • 1 1/2 cups all-purpose flour
  • 1 cup whole wheat flour
  • 1 cup old-fashioned oats
  • 1 cup granulated sugar
  • 1 tablespoon baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 2 cups plain 2% Greek yogurt
  • 1/2 cup milk
  • 1/4 cup coconut or canola oil (melt the coconut oil; melted butter may also be used)
  • 2 teaspoons vanilla extract
  • 1 large egg, lightly beaten
  • 1 large or 2 small overripe bananas, well mashed
  • 2 cups fresh blueberries (or half blueberries, half black raspberries)

Optional toppings

  • crumble topping (see notes), coarse sugar, sliced almonds, additional oats, or shredded coconut

Instructions

  1. Preheat oven to 400℉ and grease or line 20 muffin cups.
  2. Combine flours, oats, sugar, baking powder, baking soda, and salt in a large bowl. Make a well in center of the mixture and set aside.
  3. Combine the yogurt, milk, oil, vanilla, egg, and banana in another large bowl.
  4. Gently fold in the berries, stirring just enough to incorporate.
  5. Add the yogurt and fruit mixture to the flour mixture and stir just until moistened.
  6. Using a large ice cream scoop, fill the muffin cups.
  7. Sprinkle with one of the desired toppings if you wish, and then bake for 15-18 minutes or until the muffins pass the toothpick test. Be careful not to over-bake.
  8. Cool in pans for 10 minutes, and then remove to a wire rack.

Notes

For a crumble topping: In a medium bowl, combine ½ cup all-purpose flour and ⅓ cup granulated or brown sugar (can use half and half), and ½ teaspoon cinnamon (optional). Slowly drizzle in 4 tablespoons melted butter (I use salted; may use unsalted), stirring the crumbs with a fork. Avoid over-mixing; otherwise you'll end up with a thick paste. You're aiming for large crumbles. Store the mixture, covered, in the refrigerator for use on muffins, quick breads, and pies.
