How to Make Brownie Baked Oatmeal
For the complete recipe and measurements, scroll to the recipe card at the bottom of this post.
Step 1: Preheat the oven to 350 degrees Fahrenheit. Prepared a 9 x 13-inch baking pan with non-stick cooking spray.
Step 2: In a large mixing bowl, whisk together all of the wet ingredients until combined.
Step 3: Add the oats, gluten-free flour, salt, cocoa powder, and protein powder (if using). Whisk until the clumps of cocoa powder are dissolved.
Step 4: Pour the oatmeal batter into the prepared baking pan. Sprinkle the chocolate chips on top. Bake for 35 - 37 minutes, or until the baked oatmeal doesn’t jiggle in the center and bubbles rapidly around the edges.
- Grease the Baking Pan. The oatmeal mixture gets a bit sticky as it bakes up and solidifies, so you will want to spray the pan liberally with non-stick cooking spray.
- Adjust the Maple Syrup for Sweetened Protein Powder. If using sweetened chocolate or vanilla protein powder, you will likely want to reduce the maple syrup by 1-2 tablespoons. Otherwise, the oatmeal brownies can be overly sweet.
- Use Old Fashioned Oats, not quick-cook oats or steel-cut oats. Neither quick-cook or steel-cut oats have the appropriate texture or cooking time for this recipe.
- Dark Chocolate: Enjoy an extra rich chocolate experience by using dark cocoa powder and dark chocolate chips!
- Cinnamon: If you like the flavor of Mexican hot chocolate, try mixing 1 teaspoon of ground cinnamon into the baked oat batter.
- Nuts: Add crunch and extra healthy fats to your brownie baked oats by stirring ½ cup chopped walnuts or almonds into the batter. Alternatively, you can sprinkle the nuts on with the chocolate before baking!
Serve squares or scoops of this baked chocolate oatmeal piping hot with fresh hot coffee, lattes, or even coffee boba. Drizzle it with runny nut almond butter or peanut butter or even dollop whipped cream or whipped coconut cream on top.
Thanks to their high protein and fiber content, these brownie oats are a filling breakfast on their own. For extra-hungry mornings, however, they are perfectly complemented by sliced bananas, fresh berries, yogurt, and even a blueberry spinach smoothie!
- Dairy-Free: To make this recipe without dairy, use plant-based milk, vegan butter, and vegan chocolate chips. You can also substitute coconut oil for the vegan butter if desired.
- Gluten-Free: To make gluten-free chocolate baked oatmeal, be sure to use certified gluten-free old fashioned oats.
- Refrigeration: Leftover brownie baked oats keep covered in an airtight container in the refrigerator for 3-4 days.
- Freezing: Baked oatmeal can be frozen in a freezer-safe container for up to 3 months. Defrost in the refrigerator for 4-8 hours, or until thawed through.
- Reheating: Warm individual servings of baked brownie oatmeal in the microwave on medium heat for 45 seconds - 1 minute, or until heated through.
Your baked oats are runny because they were either made with too much liquid or have not baked through entirely. Double-check the ingredient measurements to ensure that you are using the directed about of milk and make sure the oats are firm in the center before removing from the oven.
Baked oats are a delicious way to get whole-grain nutrition, protein, and more. They are also a great breakfast recipe to make ahead of time and enjoy throughout the week on easy mornings. Just heat up individual servings of the baked oatmeal and you are good to go! Furthermore, with so many ways to prepare and make baked oats, they're a great recipe to keep in your breakfast repertoire for when you want to switch things up.
Your baked oats are likely not cooked in the middle because they did not bake long enough. Always follow the recipe directions for baking times and jiggle the pan of oats before removing it from the oven. If the oats jiggle in the center, return the pan to the oven to bake further.
