Ingredients for Brownie Baked Oatmeal
Brownie Baked Oatmeal Recipe
- 2 cups rolled oats (use gluten-free oats for a gluten-free option)
- 1/3 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 1 1/2 cups almond milk (or milk of choice)
- 2 flax eggs (2 tablespoons flaxseed meal mixed with 5 tablespoons water, let sit for 5-8 minutes) or 2 eggs
- 1/4 cup agave or maple syrup (add more to taste)
- 1/2 cup unsweetened applesauce or mashed banana
- 1 scoop chocolate or peanut butter protein powder
- 1 teaspoon vanilla extract
- 1/2 cup chocolate chips
- Optional toppings: peanut butter, Biscoff or Nutella drizzles, Greek yogurt dollops, whipped cream, sliced strawberries, raspberries, maple syrup, chopped almonds, walnuts, pecans, or peanuts

How to Make This Brownie Baked Oatmeal Recipe
- Preheat your oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly spray the parchment paper with non-stick cooking spray.
- If using flax eggs, in a small bowl, whisk together 2 tablespoons of ground flaxseed meal with 5 tablespoons of water. Let it sit for 5-8 minutes to thicken and form a gel-like consistency. This mixture will act as an egg replacement in the recipe.
- In a large mixing bowl, combine the dry ingredients: 2 cups of rolled oats, 1/3 cup of unsweetened cocoa powder, 1 teaspoon of baking powder, and 1/4 teaspoon of salt. Whisk the ingredients together until they are well combined and evenly distributed. Set the bowl aside.
- In a separate mixing bowl, prepare the wet ingredients. Whisk together the flax eggs (or regular eggs), 1 1/2 cups of almond milk (or your milk of choice), 1/4 cup of agave or maple syrup (adjust the amount to your desired sweetness), 1/2 cup of unsweetened applesauce or mashed banana, 1 scoop of chocolate or peanut butter protein powder, and 1 teaspoon of vanilla extract. Ensure all ingredients are thoroughly mixed.
- Pour the wet ingredients into the bowl with the dry ingredients. Gently stir the mixture until everything is just combined. Be careful not to overmix, as this can result in a tougher baked oatmeal.
- Stir in 1/4 cup of the chocolate chips into the batter. This will add delicious pockets of melted chocolate throughout the baked oatmeal.
- Pour the batter into the prepared baking pan, spreading it evenly. Sprinkle the remaining 1/4 cup of chocolate chips on top of the batter. This will create a beautiful chocolatey crust on the finished baked oatmeal.
- Bake in the preheated oven for 40-50 minutes, or until the oatmeal is set in the center. To check for doneness, insert a toothpick into the center of the baked oatmeal. If it comes out with just a few moist crumbs, it’s ready. Avoid overbaking, as this can make the oatmeal dry.
- Remove the baked brownie oatmeal from the oven and let it cool in the pan for about 10 minutes before serving. This will allow it to set further and make it easier to slice.
- Lift the baked oatmeal out of the pan using the parchment paper overhang. Cut into squares or slices. Add your favorite toppings, such as peanut butter, Biscoff or Nutella drizzles, Greek yogurt, whipped cream, fresh berries, maple syrup, or chopped nuts.
- Serve warm and enjoy!

How to Store Baked Chocolate Oatmeal
- Room Temperature: Cover the pan tightly with plastic wrap or transfer individual slices to an airtight container. Store on the counter for up to 2 days.
- Refrigerator: For longer storage, keep the brownie baked oatmeal covered in the fridge for up to 5 days. This is an excellent option for meal prepping breakfast for the week. Reheat individual portions in the microwave for 30-60 seconds, or enjoy it cold.
- Freezer: To freeze, cut the baked oatmeal into individual portions and wrap each piece tightly in plastic wrap. Place the wrapped slices in a freezer bag or airtight container. Freeze for up to 3 months. When ready to eat, thaw overnight in the refrigerator or microwave from frozen for 1-2 minutes.
More Oatmeal Variation Ideas
- Peanut Butter Brownie Oatmeal: Swirl 2-3 tablespoons of creamy peanut butter into the batter before baking. The combination of chocolate and peanut butter is simply irresistible!
- Double Chocolate: Enhance the chocolate intensity by using chocolate protein powder instead of vanilla or peanut butter flavor. This variation is perfect for serious chocolate lovers.
- Mocha Brownie Oatmeal: Add 1 teaspoon of instant espresso powder to the dry ingredients for a delightful coffee kick that will truly wake you up in the morning.
- Mint Chocolate: Infuse a refreshing twist by adding 1/4 teaspoon of peppermint extract and using dark chocolate chips. The combination of mint and dark chocolate is a classic for a reason.
- Mexican Hot Chocolate: Add 1/2 teaspoon of ground cinnamon and a pinch of cayenne pepper to the dry ingredients for a warm and spicy flavor. This variation adds a subtle heat and complexity to the brownie oatmeal.
- Nut Butter Swirl: After pouring the batter into the pan, dollop spoonfuls of almond butter, cashew butter, or Biscoff spread on top. Use a knife or skewer to create beautiful swirls. This adds a rich and nutty flavor and a visually appealing touch.
Healthy Brownie Oatmeal FAQs
Can I make this without protein powder?
- Absolutely! Simply omit the protein powder from the recipe. The baked oatmeal will still hold together and taste delicious. If you want a slightly more structured texture, you can add an extra tablespoon of rolled oats.
What can I use instead of applesauce?
- Mashed ripe banana is an excellent substitute for applesauce. It adds natural sweetness and a slightly different flavor profile. You can also use pumpkin puree or plain Greek yogurt (though yogurt isn’t vegan).
How do I know when it’s done baking?
- The edges of the baked oatmeal will begin to pull away slightly from the sides of the pan, and the center should be set but not jiggly. A toothpick inserted into the center should come out with just a few moist crumbs, not wet batter.
Can I double this brownie baked oatmeal recipe?
- You bet! To double the recipe, use a 9×13 inch baking pan. Increase the baking time by approximately 10-15 minutes. Check for doneness starting at 50 minutes.
Is this baked chocolate oatmeal kid-friendly?
- Kids absolutely love this recipe because it tastes like a decadent brownie! To make it even more appealing, add extra chocolate chips on top or let them choose their own toppings.
