PIN IT NOW TO SAVE FOR LATER

As always, I’m constantly trying to find new ways to make breakfast delicious and healthy. I don’t want yogurt or fruit or a green smoothie; I want a pastry or bowl of cereal.

That’s why I compromise with myself and make these oatmeal bars – they’re baked so they have a better texture than regular cooked oatmeal and they taste more like a sinful treat…but they aren’t!

Making oatmeal like this will change your opinion about oatmeal, I promise. Normally when I eat cooked oatmeal I have to add a ton of brown sugar and nuts to make it edible, but with baked oatmeal I can eat it plain!

Baked Oatmeal is one of my favorite easy breakfast recipes. It tastes sinful but it’s healthier and so much better than plain old cereal.

Easy Healthier Cinnamon Sugar Baked Oatmeal Recipe

This recipe is similar to the other baked oatmeal recipes I’ve made, one with blueberries and one that makes individual muffins. It’s one bowl, easy, no mixer, and you bake it. The texture is not like your normal oatmeal – I do not like regular oatmeal but I love it baked! It’s kind of like a soft granola bar when you bake it, and it’s not mushy at all.

How do you make oatmeal in the oven?

This is a one bowl oatmeal recipe! Simply mix up your ingredients and then place the mixture in a casserole dish. It bakes up like a soft granola bar.

Baked oatmeal with banana or applesauce is a healthier breakfast!

Instead of using oil I use mashed banana in this recipe. You could also use applesauce if you don’t want to use banana.

In addition to the mashed banana or applesauce, this recipe uses:

  • Eggs
  • Brown Sugar
  • Vanilla
  • Baking Powder
  • Milk
  • Cinnamon Sugar, for flavoring

When it comes to sugar, you can omit the brown sugar an instead use:

  • Honey (1-2 tablespoons)
  • Sugar-free sweetener, like Stevia or Splenda (use about 1 1/2 to 2 tablespoons)
  • Swerve brown sugar (which is completely sugar free brown sugar) – use about 2 tablespoons or to taste.

Easily make this vegan baked oatmeal!

There are two things in this recipe that are not vegan: milk and eggs.

To substitute milk, you can use any non-dairy milk. In fact, I most often use almond milk in this recipe (I always use unsweetened) but you can use any almond or soy or nut or even oat milk.

To omit the eggs you have a few choices:

  • Use an extra 1/2 cup mashed banana or applesauce
  • Use 1/2 cup soy yogurt
  • Use 2 tablespoons ground flaxseed mixed with 6 tablespoons water to create a paste

Normally in baked goods it’s hard to substitute egg to make things vegan, but this recipe is very forgiving.

I sprinkle the top with cinnamon sugar for extra flavoring but there are so many ways you can flavor it!

Other ways to flavor this oven oatmeal:

  • Add 1 cup blueberries, chopped strawberries, raspberries or other fruit
  • Add 1 cup chopped nuts or chocolate chips
  • Add 1 teaspoon pumpkin pie spice

Warm from the oven this baked oatmeal is sweet and chewy and everything breakfast is asking for.

Made as directed this recipe has only 135 calories per serving!

  1. Do you know of any substitute for the banana? I try to eat low glycemic index/low carb. Oatmeal does ok, and I can use a brown sugar substitute, but bananas spike my sugar ?

    1. She says above: “I used mashed banana in this version, but you can use an equal amount of unsweetened applesauce if you prefer”. 🙂
