Why I Love This Recipe
Pumpkin baked oatmeal became one of my favorite breakfasts because it gives me all those cozy fall flavors without needing to make breakfast from scratch every morning. I can mix everything in one bowl, put it in the oven, and have breakfast ready for several days.
I also like that this version has more staying power than basic oatmeal. Greek yogurt, eggs, milk, and protein powder work together to add protein, while pumpkin and oats keep every serving soft and satisfying.
- It is great for meal prep. One pan gives you 8 easy servings.
- It stays moist. Pumpkin puree and Greek yogurt keep the oats from becoming dry.
- It is filling. Oats, eggs, yogurt, and protein powder make a balanced breakfast.
- The flavor is cozy but simple. Cinnamon and pumpkin pie spice give you plenty of warm flavor.
- It is easy to change. Add chocolate chips, nuts, berries, or your favorite toppings.
What You’ll Need
- 2 cups old-fashioned rolled oats
- 1 cup vanilla protein powder
- 1 teaspoon baking powder
- 2 teaspoons ground cinnamon
- 1 teaspoon pumpkin pie spice
- 1/4 teaspoon salt
- 1 1/2 cups 100% pumpkin puree
- 2 large eggs
- 1 cup plain Greek yogurt
- 1 1/4 cups milk
- 1/4 cup pure maple syrup
- 1 teaspoon vanilla extract
- 2 tablespoons melted butter, plus a little extra for greasing the baking dish
- 1/3 cup mini chocolate chips, optional
Pro Tips
- Use rolled oats, not steel-cut oats. Steel-cut oats will not soften properly with this amount of liquid and baking time.
- Check your protein powder. Some protein powders absorb much more liquid than others. If your batter seems unusually thick and dry, stir in 2–4 tablespoons of extra milk.
- Do not overbake it. The center should look set but still moist when the pan comes out of the oven.
- Let it rest before cutting. Ten minutes of cooling makes the oatmeal much easier to slice.
- Keep toppings flexible. You can leave part of the pan plain and add chocolate chips or nuts only to one side.
Tools You’ll Need
- 9-by-9-inch baking dish
- Large mixing bowl
- Medium mixing bowl
- Whisk
- Silicone spatula or wooden spoon
- Measuring cups
- Measuring spoons
- Cooling rack
- Knife and spatula for serving
Substitutions and Variations
Milk: Dairy milk, almond milk, soy milk, or oat milk can all work. Higher-protein milk will increase the protein per serving.
Greek yogurt: Plain skyr is a good substitute. For a richer version, use full-fat Greek yogurt.
Butter: Use melted coconut oil or a neutral cooking oil instead.
Maple syrup: Honey can be used in the same amount.
Protein powder: Vanilla gives the oatmeal a sweeter flavor, but unflavored protein powder also works. Different powders absorb liquid differently, so you may need a small splash of extra milk.
Chocolate chips: Leave them out, or replace them with chopped pecans, walnuts, raisins, or dried cranberries.
Make Ahead Tips
You can mix the dry ingredients the night before and keep them covered at room temperature. Mix the wet ingredients separately and refrigerate them. In the morning, combine everything and bake.
For an even easier breakfast, bake the entire oatmeal ahead of time. Cool it completely, cover it, and refrigerate it. Individual pieces reheat well throughout the week.
High Protein Pumpkin Baked Oatmeal Recipe and Instructions
Step 1: Preheat the Oven and Prepare the Pan
Preheat the oven to 350°F (175°C). Lightly grease the bottom and sides of a 9-by-9-inch baking dish with a small amount of the extra butter.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, add 2 cups old-fashioned rolled oats, 1 cup vanilla protein powder, 1 teaspoon baking powder, 2 teaspoons ground cinnamon, 1 teaspoon pumpkin pie spice, and 1/4 teaspoon salt.
Whisk until the protein powder and spices are evenly spread through the oats. Break up any small clumps of protein powder as you mix.
Step 3: Mix the Wet Ingredients
In a medium mixing bowl, add 1 1/2 cups pumpkin puree, 2 large eggs, 1 cup plain Greek yogurt, 1 1/4 cups milk, 1/4 cup pure maple syrup, 1 teaspoon vanilla extract, and 2 tablespoons melted butter.
Whisk until smooth. The mixture should be creamy and orange with no large streaks of egg or yogurt.
Step 4: Make the Oatmeal Batter
Pour the wet pumpkin mixture from Step 3 into the dry oat mixture from Step 2.
Use a silicone spatula to stir until all 2 cups oats, 1 cup vanilla protein powder, 1 teaspoon baking powder, 2 teaspoons cinnamon, 1 teaspoon pumpkin pie spice, 1/4 teaspoon salt, 1 1/2 cups pumpkin puree, 2 eggs, 1 cup Greek yogurt, 1 1/4 cups milk, 1/4 cup maple syrup, 1 teaspoon vanilla, and 2 tablespoons melted butter are evenly combined.
If using them, fold in 1/3 cup mini chocolate chips. Let the mixture sit for about 2 minutes so the oats can begin soaking up the liquid.
Step 5: Fill the Baking Dish
Pour the prepared pumpkin oatmeal batter into the greased 9-by-9-inch baking dish. Use the spatula to spread it into an even layer, making sure the oats reach all four corners.
If you are using the 1/3 cup mini chocolate chips, make sure they are spread evenly through the batter rather than gathered in one spot.
Step 6: Bake
Place the baking dish in the preheated 350°F (175°C) oven.
Bake for 35–40 minutes, until the center is set and the edges are lightly golden. A toothpick inserted near the center should come out mostly clean with a few moist crumbs.
Do not wait for the oatmeal to become completely dry. It will continue to set as it cools.
Step 7: Cool, Slice, and Serve
Remove the oatmeal from the oven and let it cool for 10 minutes. Cut it into 8 servings.
Enjoy the baked oatmeal warm as it is, or add your favorite toppings.
Why This Recipe Works (Quick Science)
Pumpkin adds moisture. Pumpkin puree contains plenty of water, which hydrates the oats as they bake and helps prevent a dry result.
Eggs create structure. As the eggs heat, their proteins firm up and help the oatmeal hold together well enough to slice.
Protein powder boosts protein but absorbs liquid. Protein powder pulls in moisture, which is why the milk, yogurt, and pumpkin are important. Using too much protein powder can make baked oatmeal dry.
Greek yogurt adds protein and softness. Its thick, creamy texture helps keep the finished oatmeal tender.
Resting helps it set. Fresh from the oven, baked oatmeal is very soft. As it cools for 10 minutes, the oats continue absorbing moisture and the proteins firm up.

Common Mistakes
Using pumpkin pie filling: Make sure the can says 100% pumpkin puree. Pumpkin pie filling already contains sugar and spices.
Using quick oats or steel-cut oats: Rolled oats give this recipe the best balance of moisture and texture.
Adding extra protein powder: More is not always better. Extra powder can quickly turn baked oatmeal dry and rubbery.
Overbaking: Take it out once the center is set. It should still feel moist rather than hard.
Cutting immediately: Give it 10 minutes to cool so the pieces hold together.
What to Serve With
For an easy breakfast, serve a warm square with fresh berries, sliced banana, or apple slices. A spoonful of Greek yogurt adds creaminess and even more protein.
For something richer, try peanut butter or almond butter on top. A small drizzle of maple syrup is also delicious if you prefer a sweeter breakfast.
Leftovers and Storage
Let leftovers cool completely before storing them.
Keep individual pieces in an airtight container in the refrigerator for up to 5 days. Reheat a serving in the microwave for about 30–60 seconds, or until warm.
You can also freeze the oatmeal. Wrap individual cooled portions well and place them in a freezer-safe container or bag for up to 3 months. Thaw overnight in the refrigerator, then reheat.
FAQ
Can I use canned pumpkin?
Yes. Canned 100% pumpkin puree is exactly what you want. Do not use pumpkin pie filling.
Can I leave out the protein powder?
You can, but the recipe’s liquid balance and protein content will change. If you leave out the full cup of protein powder, this particular version may be too wet, so it is better to use a baked oatmeal recipe designed without protein powder.
What protein powder works best?
Vanilla whey or a whey-casein blend works well. Plant-based powders can also work, but they often absorb more liquid. Add a few tablespoons of extra milk if the batter looks too dry.
Can I make it without chocolate chips?
Absolutely. They are completely optional.
How do I know when baked oatmeal is done?
The edges should be lightly golden and the center should look set. A toothpick should come out mostly clean, although a few moist crumbs are fine.
Can I eat it cold?
Yes. Once refrigerated, the oatmeal becomes firmer and is easy to eat cold. You can also warm it in the microwave.

This High Protein Pumpkin Baked Oatmeal is the kind of breakfast that makes busy mornings much easier. It is warm and cozy straight from the oven, keeps well for meal prep, and gives you pumpkin-spice flavor with a satisfying protein boost.
