YUM!! You guys. This is a winning recipe. I promise, you’ll want to save this one, or pin it, or print it or SOMETHING!!

Most mornings I eat oatmeal, so it’s important to me that I have a zillion ways to prepare it. You can see the basic structure of my current meals every single day here. But one of those ways I like oatmeal is BAKED OATMEAL.

It started with my cinnamon roll baked oatmeal here. It was my first attempt at baked oatmeal, and it did NOT disappoint!

Now, that original recipe has transformed into many different ways I make it, with many more to come.

For this Birthday Cake Baked oatmeal, I took the original recipe, made it into mini muffins, and used cake batter flavorings and sprinkles.

The full recipe made 20 mini baked oatmeal cups, which brought the calories down for each cup to 15! HOLY MOLY. That’s definitely a low calorie win to me. Of course, I’ll eat 10, but I like feeling like I have big volume for fewer calories.

How to make Baked Oatmeal

Baked oatmeal is actually very easy to make. The only hard part, is that it does take a while to cook. These mini muffins took 20 minutes, but regular size muffins, or a cake pan cake take up to an hour.

Just keep in mind the cooking time when you want to make these. The bonus, is that it stores VERY WELL. In fact, I think the leftovers, cold, are actually tastier than eating it warm. But, you decide!

Ingredients for Birthday Cake Baked Oatmeal

Here’s a list of the ingredients I used to make the baked oatmeal, with birthday flavors.

  • Almond milk (vanilla unsweetened). I do think the almond milk has a birthday batter flavor. Plus, it’s only 30 calories per cup, so that’s a definite win to me!
  • Plain nonfat Greek Yogurt– I use this a lot, especially in baking. It gives baked goods a nice texture and more protein, for not a lot of calories.
  • cake batter flavoring – This is a product I just started using when I saw it at Walmart last year. Massive flavor for zero calories!
  • Liquid egg whites – This helps the oatmeal stick together well, while bumping the protein a little more.
  • Monk sugar. You all know I use the Lakanto zero calorie sugar everywhere. It is a delicious substitute for low calorie baking, and there is no after taste to me!
  • Rolled oats – It is Oatmeal, so yeah. I used oats.
  • Baking powder, to help with the rise.
  • Salt, for flavor.
  • And then 2 tablespoons protein cookie butter, birthday cake. In total transparency, I made this recipe with and without the birthday cake protein powder, and I actually did NOT notice a difference in taste. Without the protein powder, you won’t have as much protein. However, using vanilla, or any flavor you have in your pantry would probably work. I think it doesn’t need it because of the cake batter extract.

What can you eat with baked oatmeal?

Since I’m a BIG fan of balance, (see my balanced plate meal plans here), I would look at this dish and ask myself, what’s it missing?

The only food groups missing are fruit and veggies. And since I don’t think it’s necessary to eat both at breakfast, I would just add some fruit to this meal and it covers my grains, my protein, and fruit!

If I didn’t add the protein powder, than eating baked oatmeal with eggs or turkey bacon is also a great idea.
