How to Make Cranberry Banana Oat Muffins

Mix and mash your way to the most dreamy muffins on the planet. Follow the simple steps below to nail this recipe each and every time.

  • Mash bananas. Whisk egg with buttermilk and vanilla extract. Incorporate mashed bananas into the mixture.
  • Combine dry ingredients. In small portions, mix your dry ingredients into your wet ingredients.
  • Stir in dry cranberries.
  • Pop liners into a muffin tin. Fill each hole with batter.
  • Make the crumble topping by mixing oats with brown sugar. Sprinkle on top of each muffin.
  • Bake at 350°F for 20-30 minutes. With a toothpick inserted, check the doneness of each muffin. If it comes out clean, the muffins are ready!
  • Let cool to room temperature.

Hot Tip: If you prefer, swap the brown sugar crumble for coarse white sugar. It will add a nice crunch.


What ingredient makes muffins fluffy?

Allow your buttermilk and eggs to reach room temperature before you incorporate them into the batter for the fluffiest muffins possible. This will create a smooth batter that traps heat and causes the muffins to expand and pop up.

Can you use fresh cranberries instead of dry for muffins?

Opt for dried cranberries over fresh for muffins. When fresh cranberries bake in the oven, they can turn to mush and make your muffins turn soggy. With dried cranberries, you are sure to get a sweet and tart burst of flavor without any potential for mush.

Can you bake with frozen cranberries?

You can definitely bake with frozen cranberries. However, allow them to defrost completely on the counter before using them. Strain out any excess liquid to prevent diluting your batter.

What berries are great for muffins?

Blueberries, raspberries, cranberries, and blackberries all work great for muffins. As long as the berry is seasonal and fresh, you should feel free to add it to your muffin rotation.

Storing Cranberry Muffins

  • Room Temperature – Store cranberry muffins in an airtight container on the counter for a couple of days. If you’re planning on eating them quickly, there’s no need to take up space in your fridge.
  • Refrigerator – If you plan on eating your muffins a bit more slowly, store them in an airtight container in the fridge. They should stay fresh for up to a week.
  • Freezing – If you prepped a couple of batches and want to have muffins on hand for quick breakfasts or the occasional sweet tooth, allow muffins to cool completely and place them on a baking sheet. Pop the entire baking sheet in the freezer and allow muffins to freeze in a single layer. Transfer to a freezer safe plastic bag.

Reheating Muffins: Reheat your muffins by zapping them in the microwave for 45 seconds to 1 minute. Or, pop a handful in the oven at 350°F and heat through (about 5 minutes).
