Ingredients You’ll Need for Banana Peanut Butter Baked Oatmeal Cups

Here’s everything you’ll need to make these easy and wholesome baked oatmeal cups:

• Rolled oats: For a hearty, chewy texture, use old-fashioned rolled oats, not quick-cooking oats.
• Bananas: Ripe bananas add natural sweetness.
• Peanut butter: Use natural peanut butter for the best flavor and a rich texture.
• Egg: Helps bind the ingredients together and gives structure to the oatmeal cups.
• Milk: Any milk works here (dairy or plant-based) to keep the batter moist.
• Honey or maple syrup: Adds a touch of extra sweetness to complement the bananas and peanut butter.
• Baking powder: Helps the oatmeal cups bake up light rather than dense.
• Vanilla and cinnamon: Vanilla adds depth, while cinnamon brings a warm flavor that pairs perfectly with banana and peanut butter.
• Chocolate chips: Add just the right amount of sweetness and make these oatmeal cups feel extra special.

How to Make Banana Peanut Butter Baked Oatmeal Cups

These banana peanut butter baked oatmeal cups start with mashed bananas for natural sweetness and moisture. The remaining ingredients are combined to create a thick oatmeal batter, which is portioned into a muffin pan and baked until set and lightly golden. The finished oatmeal cups are soft, hearty, and easy to enjoy as a make-ahead breakfast or snack.

This recipe is made entirely in one bowl using simple kitchen tools- no mixer required. The quick, no-fuss method keeps prep and cleanup to a minimum, making these baked oatmeal cups perfect for busy mornings or meal prep.

Serving Suggestions

These baked oatmeal cups are delicious warm or at room temperature. For a little extra, drizzle some peanut butter on top or add a few banana slices before serving. They’re great on their own and easy to grab for busy mornings or quick snacks.

Storage & Make-Ahead Tips

Store the oatmeal cups in an airtight container in the refrigerator for up to 5 days. They’re ideal for make-ahead breakfasts and snacks throughout the week.
For longer storage, freeze the fully cooled oatmeal cups in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator or reheat briefly before serving.

Variations & Substitutions

• These baked oatmeal cups are easy to customize.
• You can swap the chocolate chips for nuts or dried fruit, or use dairy-free milk and chocolate chips if needed.
• To make them gluten-free, use certified gluten-free oats—the texture stays just as good.

Helpful Tips for Best Results
