Oatmeal is a great, easy breakfast, but some days even spending 10 minutes to make it up... well that just isn't going to happen. Instead of making fresh creamy oatmeal every morning, make a bigger batch of oatmeal cups so you can have single serving baked oatmeal in the morning without actually making it every morning. If it's too hot to use your oven, try these overnight oats recipes: Overnight Oats with Yogurt, Peanut Butter Banana Overnight Oats, and Apple Cinnamon Overnight Oats.

How will this recipe make your life easier?
I saw recipes for single serving baked oatmeal on the internet and thought that sounded great, but whipping up the oatmeal, pre-heating the oven, and then baking oatmeal in the oven for one morning. Well that just isn't worth the 30+ minutes when you can make it on the stove in just 10 minutes. So instead of spending all that time and energy for one serving, let's take that same time and energy to make breakfast for the week. Refrigerate these single serving baked oatmeal cups or freeze them for later!
What makes them so good?

How do I make this oatmeal?

Preheat oven to 350 degrees, you'll bake your single serving baked oatmeal cups after assembling them. The next step is to mix the oatmeal ingredients together. Add 1 c rolled (old-fashioned) oats, 1 egg, 1 soft banana, 1-2 T honey, ½ teaspoon baking powder, 1 teaspoon cinnamon, 1 teaspoon vanilla, ½ teaspoon salt, 1 tablespoon ground flaxseed, and ¾ c milk to a medium mixing bowl.

After these ingredients are well incorporated, fold 1 c frozen berries into oatmeal mixture. I used mixed berries, but you can use any berries you want. If you want to use blackberries, cherries, or strawberries, I recommend cutting them into pieces that are about the size of a blueberry.
Next, place 6 silicone or paper muffin liners into muffin tin, spray with cooking spray. Spoon batter into muffin cups. Fill to top of cup.

Bake for 25-30 minutes, or until muffin tops are golden brown and cooked through. Test with a fork or toothpick. Transfer the single serving baked oatmeal cups to a cooling rack and then refrigerate or freeze until use. I recommend eating your single serving baked oatmeal cups warm with a smear of peanut butter.
Expert tips
- Easily double this single serving baked oatmeal cups recipe for more breakfasts. Pop the cups you won't eat within about 5 days into the freezer.
- You can use a frozen banana or a fresh one. Either way, choose a really ripe one.
- Substitute the frozen berries with fresh ones. Still cut to the size of blueberries so they're not too big to make the cups soggy.
- Refrigerate the single serving baked oatmeal cups for up to 5 days.

FAQ
My friend, Julie Harrington who is a dietitian and chef breaks down the difference between quick oats/1 minute oats and rolled oats/old fashioned oats HERE. She explains that 1 minute oats are steamed for longer than rolled oats and can't absorb as much water as rolled oats. Using 1 minute oats in this recipe may lead to oats that break apart. I recommend using rolled oats/old fashioned oats in this single serving baked oatmeal recipe for a better texture.
Yes, since the eggs in it have been cooked it's safe to keep out. But I recommend refrigerating these single serving baked oatmeal cups so they last longer. Or, if you don't want to eat them all in one week, freeze for later!
Again, Julie compares and contrasts different types of oats in her article HERE. Oatmeal is a general term for cooked oats, you can use quick oats, old fashioned oats, or steel cut oats to make oatmeal. It just depends on how much time you have to make it and which texture you prefer. I recommend using old fashioned oats in these single serving baked oatmeal cups.

What can I make with leftover ingredients?
- Oats: Peanut Butter Banana Oatmeal, Oatmeal Cherry Bars, Protein Granola
- Berries: (just swap berries for what you have) Strawberry Banana PB Smoothie, Blueberry Chocolate Muffins, Blueberry Oreo Ice Cream.
- Eggs: Sausage Egg Casserole, Breakfast Egg Sandwiches, Freezer Breakfast Tacos
