Healthy Oatmeal Brownies

These Healthy Oatmeal Brownies are a delicious guilt-free treat perfect for any occasion. Made with nutrient-rich ingredients, our healthy brownies combine the classic richness of chocolate with the hearty goodness of oats for a perfect balance of flavor and nutrition.

For the recipe I use high-quality oats, unsweetened cocoa powder, semisweet chocolate and natural sweeteners like honey or maple syrup to offer just the right amount of sweetness, while keeping these brownies free from refined sugars.

To add an extra layer of nourishment, I’ve included creamy peanut butter and buttermilk, which not only enhance the texture but also boost the overall health benefits. The result is a moist brownie that’s rich in protein, vitamins, and minerals.

Perfect for breakfast, a midday snack, or a post-dinner dessert, our healthy oatmeal brownies are a great addition to any diet.

How to make oatmeal brownies

Begin by preheating the oven to 350°F (180°C). Butter the sides and bottom of an 8-inch (20 cm) square baking pan and line it with parchment paper for easy removal.

In a large bowl, whisk together the eggs and honey until well combined. Add the vanilla extract and peanut butter (or vegetable oil) and mix well to combine. Incorporate the buttermilk, continuing to mix until the batter is smooth.

Next, add the salt, baking powder, cocoa powder, and oats to the bowl, mixing well to ensure all ingredients are evenly distributed. Fold in ⅓ cup (60g) of chocolate chips or chunks, blending them into the batter.

Pour the batter into the prepared pan, spreading it evenly. Sprinkle the remaining chocolate chips or chunks on top for an extra chocolatey finish.

Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center comes out clean. Allow the brownies to cool slightly before serving. Enjoy these delicious, chocolatey treats warm or at room temperature.
