Peanut Butter & Jelly Baked Oatmeal Cups

Baked Oatmeal Cups are a simple, make-ahead breakfast recipe that makes a healthy grab-and-go breakfast or filling snack. Naturally sweetened and studded with peanut butter and jelly, these Oatmeal Cups are reminiscent of a childhood favorite sandwich!

Oatmeal is a staple at our house on weekday mornings. From Overnight Oats to Slow Cooker Maple Brown Sugar Oatmeal to Instant Pot Oatmeal to these Baked Oatmeal Cups, we rely on oatmeal to power us through our busy mornings.

On mornings when time is limited, these oatmeal cups are our breakfast of choice, as they can easily be enjoyed on the go!

Notes on Ingredients

• Oats: Use quick-cooking or old-fashioned rolled oats for this recipe. Steel-cut oats will not work for baked oatmeal cups.
• Banana: Ripe bananas will help to naturally sweeten the oatmeal cups without the need for adding sugar.
• Applesauce: Be sure to use unsweetened applesauce, not sweetened applesauce to control the added sugars. Homemade applesauce and Instant Pot applesauce work well.
• Milk: Use any variety of milk or nondairy milk.
• Peanut Butter: Use any peanut butter, or nut butter, you like for these muffins. Creamy is best for consistency, but if you only happen to have crunchy peanut butter on hand, it will work.
• Jelly: Use any jelly or jam you like to add flavor and interest to these oatmeal cups. I use All-Fruit Jam or Homemade Chia Jam, to control the added sugars.
• Flaxseed: Ground flaxseed is completely optional, but I love adding it to the oatmeal cups for added fiber, nutrients, and Omega fatty acids.

Oatmeal Cup Modifications

• Egg-Free Oatmeal Cups: Instead of using an egg in the oatmeal cup batter, mix 1 tablespoon of ground flaxseed with 3 tablespoons of water and let sit for 5 minutes before adding to the batter in place of the egg.
• Dairy-Free Oatmeal Cups: Use your favorite non-dairy milk.
• Vegan Oatmeal Cups: Use a flax egg in place of the egg AND non-dairy milk.
• Gluten-Free Oatmeal Cups: Be sure your oats are labeled certified gluten-free. Oats are naturally gluten-free, but there can be cross-contamination.
• Nut-Free Oatmeal Cups: Use soy butter or sunflower seed butter in place of the peanut butter.
• Peanut Butter Oatmeal Cups: Omit the jelly filling, and prepare the muffins as directed. You may also want to add a ¼ cup of maple syrup to the batter to account for the sweetness the jelly gives the muffins.
• Peanut Butter Chocolate Chip Oatmeal Cups: Omit the jelly and stir ½ cup of chocolate chips into the batter before baking.

How to Make Baked Oatmeal Cups

• Prepare a 12-cup muffin tin by lining it with muffin liners or greasing well.
• In a large mixing bowl, mash the bananas until smooth.

• Add the egg, applesauce, vanilla extract, milk, flaxseed, and peanut butter and mix until well combined.
• Add in the oats and stir until the oats are moistened and everything is well combined.
• Let the batter sit for 10 to 30 minutes for the oats to absorb the liquids and soften.

• Fill each muffin cup ½ of the way with the batter.
• Add a teaspoon of jelly to each muffin.
• Add another 1-2 tablespoons of the oatmeal batter to cover the jelly.

• Bake the oatmeal cups are set, like a muffin.

Storage and Reheating Instructions

These oatmeal cups are perfect to keep on hand for breakfast on the go, school lunches, car trips, or even just an afternoon snack.

• Refrigerate: Once the muffins are baked, cool them completely. If using silicone muffin liners, remove the muffins from the liners. Place the muffins in an airtight container and store them in the refrigerator for up to 5 days. Enjoy cold, at room temperature, or heat for 20-30 seconds until warmed through.
• Freeze: Alternatively, place the cooled muffins into a freezer-safe bag and freeze for up to 3 months. Reheat the oatmeal cup by placing the frozen oatmeal cup in the microwave for 45 to 60 seconds, or until fully defrosted and warm.
