Tips for making Banana Walnut Chocolate Chip Baked Oatmeal
When it comes to my banana recipes, I always have a huge stockpile of bananas. Once they are past the point where anyone in my house will eat them I stick them into the freezer in their peels and let them stay there until I need them for a recipe. When I’m ready to use them I either let them defrost on the counter or stick them in the microwave for 30 seconds at a time until they are defrosted.

Feel free to change up the mix-ins! If you don’t like chocolate chips or walnuts those can be substituted for any kind of chocolate or other candy chips, other nuts, dried fruit, etc. Another delicious baked oatmeal recipe to try is our Raspberry Chocolate Chip Baked Oatmeal Muffins.

Either quick or old fashioned oats will work well for this recipe. Do not use instant oats as they are cut too thin for them to work in baking.
Baked oatmeal is best stored in an air tight container with a paper towel underneath (to absorb moisture) for up to 3 days. If you want to keep these longer, go ahead and individually bag and store in the freezer. Defrost at room temperature before eating.
Yes, just be sure to use certified gluten-free oats as other oats are often contaminated with gluten containing ingredients.
