Step‑by‑Step Instructions for Vegan Oreo Brownies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking pan and line it with parchment paper for easy removal of your delicious Vegan Oreo Brownies. This ensures they come out perfectly without sticking, making for a smoother serving experience.
Step 2: Make the Flax Egg
In a small bowl, mix 1 tablespoon of ground flax seeds with 2.5 tablespoons of water. Allow this mixture to sit for about 5-10 minutes until it thickens and resembles the texture of an egg. This flax egg serves as a great binding agent, perfect for our rich brownie batter.
Step 3: Mix Dry Ingredients
In a large mixing bowl, combine 1 cup all-purpose flour, 1 cup powdered sugar, 1/2 cup unsweetened cocoa powder, 1 teaspoon baking powder, and a pinch of salt. Whisk these dry ingredients together until well blended. This step is crucial for achieving the perfect structure in your brownies, so ensure even mixing for a consistent texture.
Step 4: Combine Wet Ingredients
In a separate bowl, whisk together 1 cup of unsweetened soy milk, the prepared flax egg, 1/3 cup vegetable oil, and 1 teaspoon vanilla extract. Mix until smooth and uniform. The wet ingredients infuse moisture and flavor into your Vegan Oreo Brownies, ensuring a fudgy texture that everyone will love.
Step 5: Mix Together
Pour the wet mixture into the bowl of dry ingredients. Stir just until everything is combined; be careful not to overmix, as this can lead to cakey brownies instead of fudgy ones. Once blended, your brownie batter should be thick and decadent, ready for the next step.
Step 6: Spread the Batter
Transfer the brownie batter into your prepared baking pan, smoothing it evenly to the edges with a spatula. Ensure an even layer for consistent baking. The rich, dark batter should fill the pan almost to the top, promising a delightful treat packed with flavor.
Step 7: Add Oreo Topping
Crush several Oreo cookies and sprinkle them over the brownie batter, pressing them in gently. This step combines chocolatey richness with a cookies ‘n cream element that will make these Vegan Oreo Brownies truly irresistible. Ensure the cookies are evenly distributed for that perfect crunch in every bite.
Step 8: Bake to Perfection
Place the baking pan in your preheated oven and bake for 30-35 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs. Keep an eye on them to prevent overbaking, which can affect their fudginess.
Step 9: Cool and Slice
Once baked, remove the pan from the oven and let the brownies cool in the pan for about 10 minutes. Transfer to a wire rack to cool completely. Once cooled, use a sharp knife to slice them into squares. Your Vegan Oreo Brownies are now ready to be served, offering a delightful treat that can surely bring smiles to everyone’s faces!

Expert Tips for Vegan Oreo Brownies
-
Fresh Flax Seeds: Use finely ground and fresh flax seeds for optimal binding. If they’re old, your brownies may not hold together well.
-
Avoid Overmixing: Stir just until combined to keep the texture fudgy. Overmixing can lead to cakey brownies, which isn’t the goal for these Vegan Oreo Brownies.
-
Oven Timers: Start checking for doneness a little before the suggested time. Every oven is different, and removing them a minute or two early can ensure perfect fudginess.
-
Uniform Baking: Ensure the brownie batter is evenly spread in the pan for consistent baking. Uneven baking can lead to some parts being overcooked while others remain gooey.
-
Customize Flavors: Feel free to get creative! Experiment with different flavored sandwich cookies or add nuts for extra texture. Always make sure that your mix-ins complement the fudgy brownie base.

Vegan Oreo Brownies Recipe FAQs
How do I choose the right ripeness of ingredients, like ground flax seeds?
Absolutely! When selecting ground flax seeds, look for a freshly ground option, ideally stored in a cool, dark place. If they smell nutty, they are fresh. Old flax seeds will lose their efficacy as a binding agent. You can also use chia seeds as a substitute if you can’t find flax.
How should I store Vegan Oreo Brownies and how long do they last?
You can store your Vegan Oreo Brownies in an airtight container at room temperature for up to 5 days, keeping their fudgy texture alive! If you want them to last longer, refrigerate them for up to a week; just let them come back to room temperature before enjoying for the best experience.
Can I freeze the Vegan Oreo Brownies? If so, how?
Very! To freeze your brownies, cut them into squares and place them in an airtight container or a freezer bag, separating layers with parchment paper to prevent sticking. They’ll stay delicious for up to 3 months! Simply thaw them overnight in the fridge or at room temperature when you’re ready to indulge.
What should I do if my brownie batter seems too dry or thick?
If your brownie batter appears too dry, it’s often due to measuring flour too densely. To fix this, add a tablespoon of plant-based milk at a time until it reaches a smooth consistency. Remember, the batter should be thick but not dry; aim for a fudgy texture that spreads easily in the pan.
Are there any dietary considerations for pets or allergies regarding this recipe?
Yes! This recipe is vegan, making it a great option for those avoiding animal products, but be cautious with Oreo cookies. They might contain allergens such as gluten or soy. If you have pets, especially dogs, avoid giving them these brownies, as chocolate can be harmful to them. Always check labels to ensure safety!
Can I use a different type of milk or flour in this recipe?
Definitely! You can substitute the soy milk with almond milk or any other plant-based milk you prefer. For the flour, a gluten-free flour blend works well, though the texture might vary slightly. Just make sure whatever substitutes you choose are suitable for your dietary needs!
