I have shared countless baked oatmeal flavors in the past, and I love them all. But, some days, you are on your own, and all you need is a single-serve baked oatmeal recipe.

This baked oatmeal for one, is perfect if you are after an easy healthy breakfast and classic baked oatmeal recipes are too big for you. Or, simply try the flavor and taste of baked oatmeal.

What’s A Single-Serve Baked Oatmeal?

A single-serve baked oatmeal is a baked version of oatmeal for one person.

It’s not the same as a blended baked oats recipe where the ingredients are blended in a blender before baking.

Both are single-serve oat recipes, but baked oatmeal is made from whole oats. It’s creamier, not as firm and cake-like as baked oats, and has pieces of chunky oats in the batter.

How To Make Single-Serve Baked Oatmeal

This recipe is very easy to put together, and there’s an option to make it allergy-friendly, see notes below.


All you need to make a single serving of baked oatmeal are:

  • Quick Cooking Oats – You can also use old-fashioned rolled oats or a combination of both. I prefer quick oats for the single-serving recipe because oatmeal taste closer to a single-serve cake.
  • Cinnamon
  • Baking Powder – This is optional, but it raises the oatmeal a bit and makes the recipe fluffier.
  • Maple Syrup or any refined sugar-free liquid sweetener you love, including coconut nectar, date syrup, or rice syrup.
  • Egg – You can make this baked oatmeal without eggs. See options below.
  • Milk of Choice – I like unsweetened almond milk, but soy milk, regular milk, or coconut milk works well.
  • Vanilla Extract
  • Berries to chocolate chips for flavors.
  • Pinch of Salt – optional.


Preheat the oven to 350°F (180°C). Grease a small baking dish (mine is a 5-ounce oven-safe ramekin) with cooking oil spray.

You can use a wider dish, but the recipe bakes faster. Set aside.

In a mixing bowl, beat the egg with milk, vanilla extract, and maple syrup.

Stir in the oats, cinnamon, and baking powder.

Finally, mix in some berries or chocolate chips.

Pour the baked oatmeal batter into the prepared ramekin.

Bake on the center rack for 25 to 35 minutes or until the top is golden brown, set, and not jiggly in the center.

The baking time varies depending on the texture of the oatmeal you love. I like my oatmeal dry, so I slightly overbake mine.

Serve your baked oatmeal in the ramekin used for baking, don’t unmold it.

This means you need to wait a few minutes before serving to avoid burning yourself, as the ramekin is hot.

Serve plain, or with a drizzle or a pinch of:

  • Nut Butter like peanut butter or almond butter
  • Maple Syrup
  • Chopped Nuts for some crunch

Baked Oatmeal Flavors

This recipe is extremely versatile and can be adapted to create a range of delicious breakfast flavors.

My favorite variations are:

  • Carrot Cake – Stir two tablespoons of grated carrots with one tablespoon of chopped walnuts and dried raisins.
  • White Chocolate Cranberries – Stir one tablespoon of each white chocolate chips and another one of dried cranberries.
  • Mixed Berries – Add two tablespoons of mixed berries to the batter. You can roll them in cornstarch before adding them to prevent the berries from sinking to the bottom of the ramekin.
  • Banana Bread – Replace the egg with 3 tablespoons of mashed banana and stir in 1 tablespoon of chopped pecan.
  • Protein Baked Oatmeal for one. Replace the egg with one tablespoon of protein powder, a tablespoon of chia seeds, and two extra tablespoons of milk.
  • Chocolate – Stir one tablespoon of cocoa powder and a teaspoon of chocolate chips.

Storage Instructions

You can double or triple the recipe to make more single-serve oatmeal and rewarm it the following days in the microwave.

Store the recipe, in the ramekin, with a piece of foil or plastic wrap on top of it to prevent the top from drying out. Place it in the fridge and keep it for up to 4 days.

Allergy Swaps

Below are some ingredient substitution ideas if you need them.

  • Egg-Free – There are many options to replace eggs in this baked oatmeal recipe. Try 3 tablespoons of mashed banana, unsweetened apple sauce, or a tablespoon of chia seeds.
  • Dairy-Free – The best dairy-free milk for this recipe is almond milk, oat milk, or coconut milk.
  • Vegan – Use both options above.
  • Gluten-Free – Use certified gluten-free oats and wheat-free baking powder
  • Nut-free – swap almond milk for soy milk, milk, or coconut milk
  • Sugar-free – you can skip sweeteners, or use mashed banana for natural sweetness

Frequently Asked Questions

Below are my answers to your most current questions about this recipe.

Why Does My Baked Oatmeal Taste Eggy?

Single-serve oatmeal contains one egg for a small portion.
It makes it a relatively large egg-to-oat ratio compared to large-batch oatmeal recipes. As a result, you can taste the egg.
You can fix that by replacing the egg with a flax egg – stirring one tablespoon of flax meal into three tablespoons of water. When the mixture is thick, use it as an egg replacer.

How Much Oat Should I Eat A Day?

There is no maximum amount of oats you should eat per day.
Like any food, you shouldn’t overeat it. A balanced diet is about eating the rainbow and a variety of food.
A regular serving of oats for breakfast is from 1/3 cup to 1/2 cup. If you eat more oats, it can cause bloating because it’s a high-fiber grain.

What is one serving of old-fashioned oats?

A serving of oats varies from 1/3 cup to 1/2 cup, depending on body size and workout activity.
If the oats are combined with other ingredients like eggs or milk, the recipe often calls for 1/3 cup as the mix of ingredients makes the recipe very filling with just 1/3 cup of oats.

Is Baked Oatmeal As Good For You As Regular Oatmeal?

Absolutely yes! Both use the exact same ingredients, except that baked oatmeal often uses an egg to add creaminess and proteins.
