Key Lime Baked Oatmeal Cups

For a sweet, yet heart-healthy breakfast, these key lime baked oatmeal cups are fantastic! Perfect to make ahead and enjoy all week long!

Baked oatmeal is one of my favorite breakfast options! A little prep on Sunday means a fun and healthy breakfast ready for the week! There are so many flavor variations and it's something I always look forward to! Cute and tasty, my niece and nephew even refer to them as muffins or cupcakes.

In the spring and summer, citrus often becomes my flavor go-to.

Steps to Make Key Lime Baked Oatmeal

  1. Preheat the oven to 350 degrees.
  2. In a large mixing bowl, whisk the melted butter, applesauce, maple syrup, lime zest, lime juice, and eggs. Then, whisk in the baking powder, salt, and flour or protein powder. Carefully whisk in the milk. Next, fold in the old-fashioned or rolled oats and white chocolate chips.
  3. Scoop about 1/4 cup of batter into 12 lined muffin cups. I recommend lightly spraying paper muffin liners. Then, bake for 30 minutes. You can also bake in a greased 9x13 baking dish.
  4. If desired, melt about 1/4 - 1/3 cup of white chocolate chips and drizzle over the oatmeal cups. Or you can whisk together melted butter, lime juice, and powdered sugar until a thick glaze forms. Then, use a spoon to drizzle over the oatmeal.

What are key limes?

Grown in Florida and California, key limes are small with a light yellow color. They are known for being tart and fragrant. Their skin is much thinner, making them last for only a few days. Most notably, they are used for key lime pies. These little babies only produce about 2-3 tsp. of juice. I often can't find them in my local grocery store. For this recipe, you can use regular limes. So, technically this is not key lime baked oatmeal...but it just sounds so much better!

Can I add protein powder to my baked oatmeal?

Absolutely! I usually do. If you’re not going to serve the oatmeal with a protein (eggs, yogurt, etc.), I would definitely add some protein to help balance the carbs. For a baked version, I will use flour OR protein powder, not both.

Can you freeze baked oatmeal?

Yes, baked oatmeal freezes very well! Keep in an airtight container for up to 3 months!

Storage

Baked oatmeal should be stored in the fridge for 4-5 days. To reheat- simply microwave for 20-30 seconds. Baked oatmeal can also be enjoyed cold!
