If you’ve ever wanted to eat a brownie for breakfast and feel good about it, this one’s for you. My Peanut Butter Brownie Baked Oatmeal is warm, gooey, chocolatey, and secretly good for you. It’s made with simple pantry ingredients, comes together in minutes, and tastes like a peanut butter cup in oatmeal form. I love baking this on slow mornings when I want something cozy but still packed with nutrients. And yes, I drizzle mine with brownie batter granola butter because why not?

Method

1. Preheat the Oven

Start by preheating your oven to 350°F (175°C). This step is key because you want your oven to be hot and ready once your batter is blended and poured. If your oven isn’t preheated, the oatmeal may bake unevenly or take longer to cook through.

2. Blend the Ingredients

In a blender or small food processor, combine all the main ingredients   ½ a ripe banana, ⅓ cup of rolled oats, 1 tablespoon of cocoa powder, 1 tablespoon of peanut butter powder (or regular peanut butter if you’re substituting), ¼ teaspoon of baking powder, a pinch of salt, ½ cup of milk (any kind works), 1 tablespoon of maple syrup, and a splash of vanilla extract. Blend everything until the mixture is completely smooth. You’re looking for a thick, creamy batter similar to brownie batter. This step is important for the final texture. If you skip the blending, the oatmeal won’t bake into that soft, cake-like consistency.

3. Prepare the Ramekin

Lightly grease an oven-safe ramekin or small baking dish with oil or non-stick spray to prevent sticking. You can also use a non-stick ramekin if you prefer to skip the oil. This makes cleanup easier and ensures your oatmeal lifts out without breaking apart.

4. Pour and Top

Pour the blended batter into your prepared ramekin. Use a spoon or spatula to smooth the top if needed. Now comes the fun part topping it off with chocolate chips. I usually go with a small handful scattered across the top. As it bakes, these will melt slightly and create that gooey, chocolatey finish.

5. Bake the Oatmeal

Place your ramekin on the center rack of the oven and bake for 20 minutes. Every oven is different, so it’s a good idea to start checking around the 18-minute mark. You’ll know it’s done when the top looks set and slightly cracked. A toothpick inserted in the center should come out mostly clean if there’s a little chocolate from the chips or a touch of moisture, that’s totally fine.

6. Cool and Finish

Once baked, carefully remove the ramekin from the oven using oven mitts and let it cool for a couple of minutes. This gives the chocolate chips time to settle and the oatmeal time to firm up slightly. To finish, I love drizzling a spoonful of brownie batter granola butter over the top. You can also use regular peanut butter or skip the drizzle altogether it’s up to you. Either way, you’re in for a warm, rich, brownie-like breakfast that feels like dessert.

• Make it even more indulgent with a drizzle of melted dark chocolate.

Fun Fact

Did you know peanut butter powder is made by pressing roasted peanuts to remove most of the oil and fat? You still get that peanutty flavor with fewer calories and it blends perfectly into batters like this one.
