1-First Step: Preparation and Mise en Place Begin by preheating your oven to 350°F (177°C) and preparing your muffin pan. Grease or spray a 12-cavity muffin pan well to prevent sticking, as paper liners might not work best for these banana baked oatmeal cups. This step sets the stage for even baking and makes cleanup easier, and for vegan adaptations, ensure your spray is plant-based.

2-Second Step: Mixing the Dry Ingredients In a large bowl, combine 2 and 1/4 cups of old-fashioned rolled oats, 1 teaspoon of baking powder, 1/2 teaspoon of ground cinnamon, and 1/4 teaspoon of salt. Stir them together until everything is evenly mixed this creates the base for your banana oatmeal cups and ensures the flavors blend well. For gluten-free versions, double-check that your oats are certified gluten-free to keep the texture light and airy.

3-Third Step: Preparing the Wet Ingredients In another bowl, mash 1 cup of banana (from about 2-3 very ripe ones) and then whisk it together with 3/4 cup of milk, 1/4 cup of honey, 1 large egg, and 1 teaspoon of pure vanilla extract. This mixture adds moisture and sweetness to your banana baked oatmeal cups, making them irresistibly tasty. If you’re going vegan, substitute the egg with a flax egg for the same binding effect without altering the low-calorie profile.

4-Fourth Step: Combining and Adding Mix-Ins Pour the wet ingredients into the bowl with the dry ones and mix until fully combined the batter will be a bit liquidy, which is normal for baked banana oatmeal cups. At this point, fold in any optional mix-ins like 1/2 cup of chopped walnuts, 1/2 cup of semi-sweet chocolate chips, or 1 cup of fresh blueberries for extra flavor and texture. This step allows for easy low-calorie modifications by reducing or omitting the mix-ins to suit your needs.

5-Fifth Step: Filling and Baking Evenly distribute the batter into the prepared muffin pan cavities, filling each one about three-quarters full to allow for rising. Bake at 350°F (177°C) for 20-25 minutes, or until the tops are set and firm this timing ensures the cups have a perfect chewy texture. For larger muffins or gluten-free adaptations, you might need to increase the baking time slightly to achieve that ideal doneness.

6-Final Step: Cooling and Serving Once baked, let the banana baked oatmeal cups cool in the pan for 10 minutes before transferring them to a wire rack to cool completely. This helps them set properly for easy handling, and you can serve them warm with a bit of yogurt for a complete meal. They’re versatile too, so for dietary tweaks like vegan options, they’ve held up well and taste just as great the next day. Explore more oatmeal recipes like this one for inspiration.
