Let’s Make It Together

How to Make 3 Ingredient Banana Oat Muffins

  1. Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or lightly grease it with cooking spray for easy removal.

  2. In a large mixing bowl, mash the ripe bananas with a fork until they’re creamy and smooth. The more overripe they are, the sweeter and more flavorful your muffins will be!

  3. Add the rolled oats to the mashed bananas, mixing until combined. The oats soak up the banana flavor and create a satisfying texture.

  4. Slowly pour in the milk, stirring until everything is evenly mixed. Don’t worry if the batter looks a bit thick; it will rise beautifully as it bakes.

  5. Spoon the batter into the prepared muffin tins, filling each cavity about two-thirds full. This will give them room to rise without overflowing.

  6. Bake in the preheated oven for 15-20 minutes, or until the tops are golden and a toothpick inserted in the center comes out clean. Your kitchen will fill with a heavenly aroma!

  7. Remove the muffins from the oven and allow them to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.

Delicious Variations to Try

While these 3 Ingredient Banana Oat Muffins are delightful on their own, the possibilities for customization are endless! Here are a few scrumptious ideas:

  • Add a sprinkle of cinnamon or nutmeg for a warm, spicy flavor that complements the bananas perfectly.
  • Stir in a handful of chocolate chips or dried fruits like cranberries or raisins for a rich, indulgent twist.
  • For a nutty crunch, fold in some chopped walnuts or pecans, adding a delightful texture to each bite.
  • Feeling adventurous? Swap out the milk for almond milk and add a dash of maple syrup for an extra layer of sweetness.

Chef Emma’s Helpful Tips

  • Make-Ahead Advice: You can easily double this recipe and freeze the leftovers. Simply pop them in a freezer-safe bag, and they’ll be ready for a quick breakfast or snack anytime.
  • Ingredient Swaps: If you’re out of rolled oats, quick oats will work just fine. Just keep in mind that the texture may be slightly different.
  • Slicing Tricks: For clean muffin tops, use a serrated knife to gently slice them in half when serving. This also makes for a lovely presentation when you butter them warm!
  • Storage Suggestions: Keep your muffins in an airtight container on the counter for up to three days. If you plan to keep them longer, store them in the fridge or freeze them.
