Key Ingredients & Substitutions
Rolled Oats: These oats provide a chewy texture and are the base of the dish. If you need a gluten-free option, choose certified gluten-free oats.
Protein Powder: I recommend using vanilla-flavored protein for a nice taste. If you’re looking for a dairy-free option, plant-based protein powders work well. You can also skip it entirely, but consider adding more yogurt for protein.
Greek Yogurt: This adds creaminess and extra protein. If you want a dairy-free option, use coconut yogurt or silken tofu blended until smooth.
Milk: Any milk works here—dairy, almond, oat, or soy. If you prefer a creamier texture, use whole milk or nut milk alternatives.
Sweeteners: Maple syrup or honey adds sweetness. For lower sugar, consider mashed ripe banana or applesauce. Adjust to your taste!
How Do I Ensure the Perfect Bake?
Getting that perfect texture for your baked oatmeal is crucial. Aim for a moist but set consistency. Here are tips to achieve that:
- Preheat your oven for even cooking. An accurate temperature is key.
- Check for doneness at around 25 minutes. The top should be slightly golden and a toothpick should come out clean.
- Let it cool for a few minutes before serving. This allows it to firm up more.
By using these tips, you can enjoy a delicious and satisfying baked protein oatmeal every time! Happy baking!

- 1 cup rolled oats
- 1 scoop vanilla protein powder (about 25-30g)
- 1 tsp baking powder
- 1/2 tsp ground cinnamon
- Pinch of salt
- 1 large egg
- 1 cup milk (dairy or unsweetened plant-based)
- 1/2 cup plain Greek yogurt
- 1-2 tbsp maple syrup or honey

- 1/2 cup fresh or frozen blueberries (plus extra for topping)
- 1/4 cup fresh raspberries (for topping)
- 1-2 tbsp peanut butter or almond butter (for drizzling)
How Much Time Will You Need?
This recipe will take about 10 minutes to prep and around 30 minutes to bake. In total, you’re looking at about 40 minutes from start to enjoying your delicious baked protein oatmeal!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This helps your oatmeal bake evenly. While your oven is heating, lightly grease an 8×8-inch baking dish or any similar size ramekin to prevent sticking.
2. Mix the Dry Ingredients:
In a large mixing bowl, combine the rolled oats, protein powder, baking powder, ground cinnamon, and a pinch of salt. Stir them well so that everything is evenly mixed.
3. Combine the Wet Ingredients:
In another bowl, whisk together the egg, milk, Greek yogurt, maple syrup or honey, and vanilla extract until you have a smooth mixture. This will give your baked oatmeal a nice creamy texture!
4. Combine Both Mixtures:
Pour the wet mixture into the bowl with the dry ingredients. Stir everything together gently until just combined. Take care not to overmix it!
5. Add Berries:
Now it’s time to fold in the 1/2 cup of blueberries. Gently stir them in, so they’re spread throughout the mixture without getting mashed!
6. Bake:
Pour the mixture into your prepared baking dish, spreading it out evenly. Pop it in the oven and bake for about 25-30 minutes, or until the top is set and slightly golden brown. You can check for doneness with a toothpick; it should come out clean.
7. Cool and Serve:
Once it’s done, take it out of the oven and let it cool for a few minutes. This will make it easier to serve!
8. Top and Enjoy:
Before serving, sprinkle the top with the remaining blueberries and raspberries. You can also drizzle some peanut butter or almond butter for an extra delicious touch. Enjoy your warm baked protein oatmeal as a fulfilling and healthy breakfast!
This baked protein oatmeal is hearty, protein-packed, and bursting with fresh berries — a wholesome way to start the day!
Can I Use Steel-Cut Oats Instead of Rolled Oats?
While steel-cut oats can add a delicious texture, they won’t work well in this recipe without modification. If using steel-cut oats, increase the baking time and consider soaking them overnight to soften them up before baking.
Can I Make This Recipe Vegan?
Absolutely! To make the Baked Protein Oatmeal vegan, substitute the egg with a flax egg (1 tablespoon flaxseed meal mixed with 2.5 tablespoons water, let sit for 5 minutes) and use a plant-based yogurt. Also, ensure your protein powder is plant-based.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3-4 days. You can reheat individual portions in the microwave or enjoy it cold as a quick snack!
Can I Freeze Baked Protein Oatmeal?
Yes, you can freeze it! After baking, let it cool completely, then slice it into portions and wrap each slice tightly in plastic wrap before placing in a freezer-safe bag. It will keep well for up to 3 months. To reheat, thaw overnight in the fridge and warm in the microwave.
